Abstract:

Visual programming is a programming paradigm commonly used for game scripting, it also has applications in other areas such as for example patcher languages for music and animation and even a few languages for general purpose programming. By using visual programming complex tasks can be made easier by abstracting the code and letting the user express a flow of commands instead. This also gives a better overview of the problem and how the different parts connect. By graphically connecting nodes the program flow will be made clear even for those new to programming. Unfortunately, visual programming is mostly limited to laptops and stationary computer systems. Touch enabled mobile devices which perhaps would be even better suited for a visual programming approach are left with textual programming environments, which doesn’t use the capabilities of the touch screen, and a few non-graph-like visual programming languages, which use interlocked blocks to represent code. To explore how well graph-like visual programming would work on mobile devices a study will be conducted in which a lo-fi design is created and iteratively evaluated and improved using a modified NEVO process. The design will be created and improved based on existing visual programming interfaces and research in the area of visual programming, interaction design and information design, combined with the input from the test subjects. In this work a mobile, visual, graph-like, general purpose programming language has been designed. A lo-fi prototype of the language has been created to display how the language would look on a mobile system if realized. The lo-fi prototype was then tested with a method given by Rettig to give an indication of the systems usability measured by its task completion time compared to the task completion time of a mobile textual system. There is also a qualitative analysis on the responses from the test users. The tests were conducted both on people new to programming as well as people who have been programming for a while.

Abstract:

In an ever faster changing environment, software developers not only need agile methods, but also agile programming paradigms and tools. A paradigm shift towards declarative programming has begun; a clear indication of this is Microsoft's substantial investment in functional programming. Moreover, several attempts have been made to enable visual programming. We believe that software development is ready for a new paradigm which goes beyond any existing declarative paradigm: visual compositional-relational programming. Compositional-relational programming (CRP) is a purely declarative paradigm -- making it suitable for a visual representation. All procedural aspects -- including the increasingly important issue of parallelization -- are removed from the programmer's consideration and handled in the underlying implementation. The foundation for CRP is a theory of higher-order combinatory logic programming developed by Hamfelt and Nilsson in the 1990's. This thesis proposes a model for visualizing compositional-relational programming. We show that the diagrams are isomorphic with the programs represented in textual form. Furthermore, we show that the model can be used to automatically generate code from diagrams, thus paving the way for a visual integrated development environment for CRP, where programming is performed by combining visual objects in a drag-and-drop fashion. At present, we implement CRP using Prolog. However, in future we foresee an implementation directly on one of the major object-oriented frameworks, e.g. the .NET platform, with the aim to finally launch relational programming into large-scale systems development.

Abstract:

Visual Programming Languages and Visual Programming Tools incorporate non-procedural coding mechanisms that may duplicate, or perhaps even conflict with, the analysis and design mechanisms promulgated by the mainstream Software Engineering methodologies. By better understanding such duplication and conflict, software engineers can take proactive measures to accommodate and, ideally, eliminate them. Better still, there may be opportunities for synergy that can be exploited if one is looking for them. This research explored, documented and classified the interactions and interdependencies, both positive (synergies) and negative (conflicts), between two closely related and rapidly evolving Computer Science subdisciplines: software engineering and visual programming. A literature search was conducted to surface, evaluate, and build upon (where appropriate) recent and ongoing research in this area. A mechanism was created to capture observations of conflicts and synergies. This capture mechanism was applied to an experimentation test bed that was established to provide concrete examples of gaps, overlaps, conflicts, and synergies. In this regard, two relatively simple applications, one data-base oriented and one algorithm oriented, were designed and implemented using multiple software engineering methods and multiple visual tools/languages. A software prototype, which bridges one of the gaps discovered during the research, was built to underscore the importance of eventually merging Computer Aided Software Engineering and visual development tools. The overall results as well as anticipated trends and developments in the area of software engineering and visual programming were summarized. The synergy/conflict observations, in conjunction with the literature search results, were used to develop strategies and guidelines for successfully using visual programming languages and tools in concert with sound software engineering methods.

Abstract:

Decreasing enrollments, lower rates of student retention and changes in the learning styles of today's students are all issues that the Computer Science (CS) academic community is currently facing. As a result, CS educators are being challenged to find the right blend of technology and pedagogy for their curriculum in order to help students persist through the major and produce strong graduates. Visual technologies are being explored as a way to present difficult programming concepts in a manner that is easier to visualize and simpler to use. Visual technologies can make learning programming easier by minimizing the syntax of the programming language being used and providing visual feedback to the students to aid in conceptualization of the programming constructs. The goal was to improve student retention and performance by incorporating visual technologies in the introductory programming course, CS1, at East Tennessee State University (ETSU). The ADDIE approach to instructional design was used to develop and implement a curriculum that incorporated visual technologies in CS1 at ETSU. Subsequently, quasi-experimental research methods, using the Post-Test Only Nonequivalent Groups Design approach, were used to perform assessment on the effects of the revised curriculum on student performance in the course and retention in the major as compared to student performance and retention as measured prior to the course redesign. The results of the study indicate a positive impact on student performance in CS1 and student retention in the major as a result of the use of two types of visual technologies in CS1 at ETSU. Visual technologies supporting algorithm development, such as RAPTOR, had a positive impact on student performance in the area of problem solving and algorithm development as well as the use of decision and repetition constructs in programming. Visual technologies supporting program development, such as Alice, had a positive impact on student performance in the area of object-oriented programming concepts such as objects and classes. The combination of these two types of visual technologies showed evidence of improvement among student performance as a whole in the course and slight improvement in student persistence in the major.

Abstract:

The objective of this dissertation was to design and implement a platform-independent, distributed visual programming language / visual programming environment (VPUVPE) called the PictGram system. PictGram (PICTorial proGRAMming) is based on the functional programming paradigm. The PictGram system required the development of three challenging components: (1) a visual lexical specification for graphical tokens, (2) a visual syntactic definition specifying rules by which expressions can be legally combined, and (3) a visual parsing mechanism for graphically represented programs. The construction of PictGram has required an intensive analysis of theories for distributed functional programming languages, and extensive experiments of possible VPUVPE implementation. The theoretical investigation developed a formalism of functional programming language in three design phases: (1) a lexical representation of a visual primitive, (2) visually-expressed syntactic rules for the lexical representation, and (3) semantic interpretation of the visual expression. The practical experiments have integrated such formalisms into two realistic implementation components: (1) a front-end of PictGram manages a construction of the visual expression and (2) a back-end of PictGram, a distributed interpreter, evaluates the visual expression. PictGram was constructed by integrating three sub-goals: (1) to develop a theory of PictGram VPUVPE, (2) to design and implement the PictGram VPUVPE, and (3) to integrate PictGram VPUVPE with distributed interpreters. Pic/Gram allows the users to construct a graphically-represented source program. Pic/Gram translates such a graphical expression into textual expression, then uses an interpreter to evaluate the expression. The result is then translated back to an appropriate graphical form. All programming activities are supported interactively through the system's graphical user interface. This dissertation has investigated visual programming methodologies based on a functional programming paradigm, and a visual programming system, PictGram, has been suggested. A lexeme is expressed by the graphical user components, and a syntactic relationship is specified by the click-and-drop operation. The semantics of the graphically-represented source programs are interpreted by the distributed interpreters. PictGram provides a simple interface that supports a general programming language paradigm.

Abstract:

Most current DFVPLs support flow control to facilitate experiments and complex problems. However, current approaches in DFVPLs still remain inefficient. We show that inadequacies in existing visual programming languages may be magnified in applications involving image analysis. These include a lack of efficient communication mechanisms and strong dependency on human involvement to customise properties. For instance, properties in one computational component can not be shared for other components. Moreover, conditional expressions used in control components hold data values that are unrelated with those computational components. Furthermore, since image processing libraries usua.lly only explicitly support pipeline processing, as exemplified by the widely used Insight Toolkit for Medical Image Segmentation and Registration (ITK), a looping algorithm would be difficult to implement without a feedback mechanism supported by the visual language itself. We propose a data-flow visual programming language that encompasses several novel control constructs and parameterised computational units. These components are facilitated by a novel hybrid data-flow model. We also present several conceptual models and design alternatives for control constructs. Several mechanisms and techniques are provided to enhance data propagation for these components. We demonstrate, in an environment that utilises ITK as the underlying processing engine, that the inadequacies in existing DFVPLs can be satisfactorily addressed through the visual components proposed in this thesis.

ENGLISH ABSTRACT: 3D virtual environments can be used as therapy tools in patients with autism spectrum disorders (ASDs); however, the development of such tools is time-consuming. A 3D virtual environment development platform for such tools has been developed specifically for the South African context, because of the language and culture sensitivity of these therapy tools. The 3D virtual environment development platform has a Lua scripting interface for specifying logic in the virtual environments. Lua is a textual programming language, and presents a challenge to ASDs therapists’ ability to create therapy tools without engaging an expert programmer. The aim of this research was to investigate the design and implementation of a visual programming environment to support non-expert programmers in scripting within the 3D virtual environment development platform. Various visual program representation techniques, reported in the literature, were examined to determine their appropriateness for adoption in our design. A visual programming language based on the “building-block” approach was considered the most suitable. The research resulted in the development of a visual script editor (VSE), based on an open source framework called the OpenBlocks library. The VSE successfully alleviated the syntax burden that textual programming languages place on non-expert programmers. The fitness of purpose of our VSE was exemplified in a sample 3D virtual environment that was scripted using the VSE. Despite the success, we argue that the applicability of the “building-block” approach is limited to domain-specific programming languages due to the absence of visual expressions for defining user-defined types, and for specifying hierarchy.

Abstract:

Presented through contextualisation of the portfolio works are developments of a practice in which the acts of programming and composition are intrinsically connected. This practice-based research (conducted 2009–2013) explores visual representation of sound in computer music software. Towards greater understanding of composing with the software medium, initial questions are taken as stimulus to explore the subject through artistic practice and critical thinking. The project begins by asking: How might the ways in which sound is visually represented influence the choices that are made while those representations are being manipulated and organised as music? Which aspects of sound are represented visually, and how are those aspects shown? Recognising sound as a psychophysical phenomenon, the physical and psychological aspects of aesthetic interest to my work are identified. Technological factors of mediating these aspects for the interactive visual-domain of software are considered, and a techno-aesthetic understanding developed. Through compositional studies of different approaches to the problem of looking at sound in software, on screen, a number of conceptual themes emerge in this work: the idea of software as substance, both as a malleable material (such as in live coding), and in terms of outcome artefacts; the direct mapping between audio data and screen pixels; the use of colour that maintains awareness of its discrete (as opposed to continuous) basis; the need for integrated display of parameter controls with their target data; and the tildegraph concept that began as a conceptual model of a gramophone and which is a spatio-visual sound synthesis technique related to wave terrain synthesis. The spiroid-frequency-space representation is introduced, contextualised, and combined both with those themes and a bespoke geometrical drawing system (named thisis), to create a new modular computer music software environment named sdfsys.

Abstract:

Despite two decades of empirical studies focusing on programmers and the problems with programming, usability of textual programming languages is still hard to achieve. Its younger relation, visual programming languages (VPLs) also share the same problem of poor usability. This research explores and investigates the usability issues relating to VPLs in order to suggest a set of design principles that emphasise usability. The approach adopted focuses on issues arising from the interaction and communication between the human (programmers), the computer (user interface), and the program. Being exploratory in nature, this PhD reviews the literature as a starting point for stimulating and developing research questions and hypotheses that experimental studies were conducted to investigate. However, the literature alone cannot provide a fully comprehensive list of possible usability problems in VPLs so that design principles can be confidently recommended. A commercial VPL was, therefore, holistically evaluated and a comprehensive list of usability problems was obtained from the research. Six empirical studies employing both quantitative and qualitative methodology were undertaken as dictated by the nature of the research. Five of these were controlled experiments and one was qualitative-naturalistic. The experiments studied the effect of a programming paradigm and of representation of program flow on novices' performances. The results indicated superiority of control-flow programs in relation to data-flow programs; a control-flow preference among novices; and in addition that directional representation does not affect performance while traversal direction does - due to cognitive demands imposed upon programmers. Results of the qualitative study included a list of 145 usability problems and these were further categorised into ten problem areas. These findings were integrated with other analytical work based upon the review of the literature in a structured fashion to form a checklist and a set of design principles for VPLs that are empirically grounded and evaluated against existing research in the literature. Furthermore, an extended framework for Cognitive Dimensions of Notations is also discussed and proposed as an evaluation method for diagrammatic VPLs on the basis of the qualitative study. The above consists of the major findings and deliverables of this research. Nevertheless, there are several other findings identified on the basis of the substantial amount of data obtained in the series of experiments carried out, which have made a novel contribution to knowledge in the fields of Human-Computer Interaction, Psychology of Programming, and Visual Programming Languages.

Abstract:

In this paper, I survey past and present tools available to text adventure game authors, and then describe a new product: the Text Adventure Design Assistant (TA DA!), a visual programming system for creating text adventure games. My system consists of two parts: an abstract framework which defines an archetypical game, and a user interface which allows for the construction of games in a visual manner by manipulating the elements of the abstract game to produce a concrete design. The two most popular contemporary programming languages for creating text adventure games, TADS and Inform, are compared and contrasted, and my abstract framework is adapted to both of these languages. The traditional pencil-and-paper design process used by adventure game authors is studied and its application to the development of TA DA! is described. Finally, the implications of TA DA! and similar advances in visual programming are discussed and I predict future trends in the design of both adventure games and other application domains based on this work.

Learning the syntax, semantics, and concepts behind software engineering can be a challenging task for many individuals. This paper examines the Alice 3 software, a three-dimensional visual environment for teaching programming concepts, to determine if it is an effective tool for improving student achievement, raising self-efficacy, and engaging students. This study compares the similarities and differences between a Fundamentals of Programming course with and without Alice integrated into the curriculum. Both the treatment and control Groups are using the same Java materials, assignments, and exams. The treatment group also completes Alice activities for each programming concept throughout the course; as well as two Alice assignments.

Full text

Abstract:

Memory is a part of cognition. It is essential for an individual to function normally in society. It encompasses an individual's lifetime experience, thus defining his identity. This thesis develops the concept of a machine-based personal memory manager which captures and manages an individual's day-to-day external memories. Rather than accumulating large amounts of data which has to be mined for useful memories, the machine-based memory manager automatically organizes memories as they are captured to enable their quick retrieval and use. The main functions of the machine-based memory manager envisioned in this thesis are the support and the augmentation of an individual's biological memory system. In the thesis, a model for a machine-based memory manager is developed. A visual programming environment, which can be used to build context aware applications as well as a proof-of-concept machine-based memory manager, is conceptualized and implemented. An experimental machine-based memory manager is implemented and evaluated. The model describes a machine-based memory manager which manages an individual's external memories by context. It addresses the management of external memories which accumulate over long periods of time by proposing a context aware file system which automatically organizes external memories by context. It describes how personal memory management can be facilitated by machine using six entities (life streams, memory producers, memory consumers, a memory manager, memory fragments and context descriptors) and the processes in which these entities participate (memory capture, memory encoding and decoding, memory decoding and retrieval). The visual programming environment represents a development tool which contains facilities that support context aware application programming. For example, it provides facilities which enable the definition and use of virtual sensors. It enables rapid programming with a focus on component re-use and dynamic composition of applications through a visual interface. The experimental machine-based memory manager serves as an example implementation of the machine-based memory manager which is described by the model developed in this thesis. The hardware used in its implementation consists of widely available components such as a camera, microphone and sub-notebook computer which are assembled in the form of a wearable computer. The software is constructed using the visual programming environment developed in this thesis. It contains multiple sensor drivers, context interpreters, a context aware file system as well as memory retrieval and presentation interfaces. The evaluation of the machine-based memory manager shows that it is possible to create a machine which monitors the states of an individual and his environment, and manages his external memories, thus supporting and augmenting his biological memory.

Abstract:

O presente trabalho buscou identificar e analisar as formas de mediação possibilitadas pelo Scratch no processo de ensino aprendizagem de programação no Ensino Médio. Para isso, tomou como pergunta norteadora: como o Scratch pode mediar a aprendizagem de programação no Ensino Médio com vistas ao desenvolvimento do pensamento computacional a partir da teoria vigotskiana? O quadro teórico foi baseado na teoria sociointeracionista de Vigotski (2007), nos conceitos de pensamento computacional e de programação de computadores, aspirando a formação de cidadãos para o século XXI, apoiado pelas três dimensões do framework de Brennan e Resnick (2012): conceitos computacionais, práticas computacionais e perspectivas computacionais. O percurso metodológico foi delineado por um estudo de caso. Para criá-lo, foi organizada uma oficina de introdução à programação de computadores para alunos de primeiro ano do Ensino Médio Técnico de uma instituição de ensino da Serra Gaúcha. O corpus foi constituído pelos cadernos de reflexão dos alunos, pelos programas criados pelos estudantes para resolver cada tarefa, pelas anotações do pesquisador e pelo questionário pós-oficina. A análise do corpus, na busca de compreender e explicar o contexto dos alunos, atuando na oficina e utilizando o Scratch, seguiu as seguintes etapas: tabulação dos dados dos questionários pré-oficina; submissão dos programas criados pelos estudantes para resolver cada tarefa à análise do Dr. Scratch; análise por parte do pesquisador dos programas criados pelos estudantes com base no framework de Brennan e Resnick; e, análise conjunta dos cadernos de reflexão dos estudantes, das anotações do pesquisador e dos questionários pós-oficina, articulando com os resultados das etapas anteriores para construir a resposta à pergunta de pesquisa. Os desfechos alcançados apontam que o ambiente Scratch tem potencial para mediar o aprendizado de programação, proporcionando um ambiente amigável, dinâmico e motivador, com características de micromundo. Indicam ainda que o papel do professor precisa ser redimensionado. Ele precisa atuar como mediador, assim como sugere a teoria vigotskiana, criando estratégias e intervenções que tenham o potencial de levar o aluno a dar sentido às ações desenvolvidas no ambiente Scratch. Podemos dizer ainda, com base no estudo desenvolvido, que nesse contexto, os alunos podem desenvolver habilidades relacionadas ao pensamento computacional e interagir com autonomia.
The present work sought to identify and analyze the forms of mediation made possible by Scratch in the process of teaching programming learning in High School. For this, it took as a guiding question: how does Scratch can mediate programming learning in High School with a view to the development of computational thinking from the Vygotskian theory? The theoretical framework was based on the socio-interactionist theory of Vygotsky (2007), in the concepts of computational thinking and computer programming, aspiring to the formation of citizens for the XXI century, supported by the three dimensions of the Brennan and Resnick framework (2012): computational concepts, practices, and perspectives. The methodological course was delineated by a case study. To create it, an introductory computar programming workshop was organized for first-year students of the Technical High School of a teaching institution in the state of Rio Grande do Sul. The corpus consisted of students' reflection books, the programs created by the students to solve each task, the researcher's notes and the post-workshop questionnaire. The analysis of the corpus, in the search to understand and explain the context of the students, acting in the workshop and using Scratch, performed the following steps: tabulation of the data of the pre-workshop questionnaires; submission of programs created by students to solve each task to Dr. Scratch's analysis; analysis by the researcher of the programs created by the students based on the Brennan and Resnick framework; and, joint analysis of the students' notebooks, the researcher's notes and the post-workshop questionnaires, articulating with the results of the previous steps to construct the answer to the research question. The results show that the Scratch environment has the potential to mediate programming learning, providing a friendly, dynamic and motivating environment with m icroworld characteristics. They also indicate that the role of the teacher needs to be resized. Teacher needs to act as a mediator, as suggested by the Vygotskian theory, creating strategies and interventions that have the potential to lead the student to give meaning to the actions developed in the Scratch environment. We can also say, based on the study developed, that in this context, students can develop skills related to computational thinking and interact with autonomy.

Abstract:

Reading and understanding algorithms is not an easy task and often neglected by educators in an introductory programming course. One proposed solution to this problem is the incorporation of a technological support tool to aid program comprehension in introductory programming. Many researchers advocate the identification of beacons and the use of chunking as support for code comprehension. Beacon recognition and chunking can also be used as support in the teaching model of introductory programming. Educators use a variety of different support tools to facilitate program comprehension in introductory programming. Review of a variety of support tools fails to deliver an existing tool to support a teaching model that incorporates chunking and the identification of beacons. The experimental support tool in this dissertation (BeReT) is primarily designed to encourage a student to correctly identify beacons within provided program extracts. BeReT can also be used to allow students to group together related statements and to learn about plans implemented in any semantically and syntactically correct algorithm uploaded by an instructor. While these requirements are evident in the design and implementation of BeReT, data is required to measure the effect BeReT has on the indepth comprehension of introductory programming algorithms. A between-groups experiment is described which compares the program comprehension of students that used BeReT to study various introductory algorithms, with students that relied solely on traditional lecturing materials. The use of an eye tracker was incorporated into the empirical study to visualise the results of controlled experiments. The results indicate that a technological support tool like BeReT can have a significantly positive effect on student comprehension of algorithms traditionally taught in introductory programming. This research provides educators with an alternative way for the incorporation of in-depth code comprehension skills in introductory programming.

Abstract:

The use of electronic mail (email) has evolved from sending simple messages to task delegation and management. Most mail clients, however, have not kept up with the evolution and as a result have limited task management features available. On the other hand, while issue tracking systems offer useful task management functionality, they are not as widespread as emails and also have a few drawbacks. This thesis reports on the exploration of the integration of the ubiquitous nature of email with the task management features of issue-tracking systems. We explore this using simple ad-hoc as well as semi-automated tasks. With these two working together, tasks can be delegated from email clients without needing to switch between the two environments. It brings some of the benefits of issue tracking systems closer to our email users.The system is developed using Microsoft VisuaI Studio.NET. with the code written in C#. The eXtreme Programming (XP) methodology was used during the development of the proof-of-concept prototype that demonstrates the integration of the two environments, as we were faced at first with vague requirements bound to change, as we better understood the problem domain through our development. XP allowed us to skip an extended and comprehensive initial design process and incrementally develop the system, making refinements and extensions as we encountered the need for them. This alleviated the need to make upfront decisions that were based on minimal knowledge of what to expect during development. This thesis describes the implementation of the prototype and the decisions made with each step taken towards developing an email-based issue tracking system. With the two environments working together, we can now easily track issues from our email clients without needing to switch to another system.

Abstract:

This design-based research provides design considerations for developing educational tools for teaching programming to blind primary schoolers, as an effort towards more inclusive classrooms, given that the tools available today are not accessible to these students. Existing tools were analyzed and tested, and co-design practices were applied in exploring ‘instructions’ as a main logic operation for computer programming, through experimenting with diverse types of interfaces, having visually impaired participants at the center of the process. Physical and mental patterns, relevant for improving the accessibility of such tools, are unveiled and further discussed in this study.

Abstract:

According to a study at Linköping University, students who study programming need additional assistance beyond the help provided in the course. According to the same survey, the majority of these students indicate that they would pay for private tuition in programming. At the same time, there are students who believe they have the competence to teach others in programming and could consider of doing this against financial compensation. To meet these needs of students, a solution tested in this thesis resulted in the development of a web application to create a C2C platform where students can meet up to exchange knowledge within programming. The development of the web application is varied by design and functionality substantiated by scientific theories. During the project, user testing is performed to get opinions from the potential target group. The work mainly focuses on answering the research questions regardingconsumer trust of the web application’s design. The report shows that it is possible to develop a web application according to the above criteria.

Abstract:

Tools development is a sometimes overlooked process that is crucial for developing high quality games. The experience of the users will vary which makes usability an important issue as well as having good guidelines for communications and development of user interfaces. This report presents the development process of two different tools used in production of high-quality projects at Avalanche Studios and describes both the added functionality as well as the methods used to provide them.

Programmering av verktyg är en process som ofta är förbisedd men som är mycket viktig för utvecklingen av hög-kvalitativa spel. Den varierande kunskapsnivån hos användare gör att det är viktigt att fokusera på användarbarheten samt även ha bra riktlinjer för kommunikationer och utvecklingen av användargränssnitt. Den här rapporten presenterar hela utvecklingsprocessen av två olika verktyg som används vid utveckling av högkvalitativa projekt vid Avalanche Studios, och går igenom både ny funktionalitet samt även använda metoder för att uppnå detta.

Abstract:

This thesis has been carried out at the company Stakkr AB in Stockholm. Stakkr have considered moving their existing C++ code to the visual programming language Blueprints in Unreal Engine 4. The objective of this study was to examine the performance of Blueprint if it’s suitable for mobile games, as well to provide Stakkr a suitability assessment of writing code in Blueprint and examine how well it performs compared with the language programming language C++. The assessment of suitability was performed by implementing a translation of two existing C++ classes to Blueprints and an assessment was made regarding development in Blueprint and performance testing between the existing C ++ and the developed Blueprint classes. The method of execution of the assessment was to work agile in short and structured iterations. The assessment of the suitability of the study showed that it was user-friendly to develop with Blueprint. However the existing C ++ classes outperformed the classes written in Blueprints. The reason why Blueprints perform worse has been identified and recommendations regarding the performance issues have been developed.
Detta examensarbete har genomförts på företaget Stakkr AB i Stockholm. Stakkr har övervägt att flytta över sin befintliga C++ kod till det visuella programmeringsspråk Blueprints i Unreal Engine 4. Målet med detta examensarbete har varit att undersöka om prestandan i Blueprints är lämplig för mobilspel samt att tillhandahålla Stakkr en lämplighetsutvärdering av att skriva kod i Blueprints och undersöka hur bra den presterar jämfört med språkstandarden C++. bedömningen av lämpligheten utfördes genom att genomföra en översättning av två befintliga C++ klasser till Blueprints, en bedömning av att utveckla i Blueprints har gjorts och prestandatester har utförts mellan de befintliga C++ gentemot de utvecklade Blueprintklasserna. Metoden för utförandet av bedömningen var att arbeta agilt i korta och strukturerade iterationer. Bedömningen från lämplighetsundersökningen visade att det var användarvänligt att utveckla i Blueprints. Dock presterade Blueprintklasserna sämre än de befintliga C++ klasser. Anledningen till varför Blueprints presterar sämre har identifierats och rekommendationer gällande detta har tagits fram.

Abstract:

This thesis presents VERTIPH, a visual programming language for the development of image processing algorithms on FPGA hardware. The research began with an examination of the whole design cycle, with a view to identifying requirements for implementing image processing on FPGAs. Based on this analysis, a design process was developed where a selected software algorithm is matched to a hardware architecture tailor made for its implementation. The algorithm and architecture are then transformed into an FPGA suitable design. It was found that in most cases the most efficient mapping for image processing algorithms is to use a streamed processing approach. This constrains how data is presented and requires most existing algorithms to be extensively modified. Therefore, the resultant designs are heavily streamed and pipelined. A visual notation was developed to complement this design process, as both streaming and pipelining can be well represented by data flow visual languages. The notation has three views each of which represents and supports a different part of the design process. An architecture view gives an overview of the design's main blocks and their interconnections. A computational view represents lower-level details by representing each block by a set of computational expressions and low-level controls. This includes a novel visual representation of pipelining that simplifies latency analysis, multiphase design, priming, flushing and stalling, and the detection of sequencing errors. A scheduling view adds a state machine for high-level control of processing blocks. This extended state objects to allow for the priming and flushing of pipelined operations. User evaluations of an implementation of the key parts of this language (the architecture view and the computational view) found that both were generally good visualisations and aided in design (especially the type interface, pipeline and control notations). The user evaluations provided several suggestions for the improvement of the language, and in particular the evaluators would have preferred to use the diagrams as a verification tool for a textual representation rather than as the primary data capture mechanism. A cognitive dimensions analysis showed that the language scores highly for thirteen of the twenty dimensions considered, particularly those related to making details of the design clearer to the developer.

Visual perception modeling is generally weak for game AI and computer generated forces (CGF), or agents, in computer games and military simulations. Several tricks and shortcuts are used in perceptual modeling. The results are, under certain conditions, unrealistic behaviors that negatively effect user immersion in games and call into question the validity of calculations in fine resolution military simulations. By determining what the computer-generated agent sees using methods similar to that used to generate the human players' screen view in 3- D virtual environments, we hope to present a method that can more accurately model human visual perception, specifically the major problem of a entity "hiding in plain sight"

Abstract:

Performance is something that is always of concern when developing real-time 3D graphics applications. The way programs are made today with object-oriented programming has certain flaws that are rooted in the methodology itself. By exploring different programming paradigms we can eliminate some of these issues and find what is best for programming in different areas. Because real-time 3D applications need high performance the data-oriented design paradigm that makes the data the center of the application is experimented with. By using data-oriented design we can eliminate certain issues with object-oriented programming and deliver improved applications when it comes to performance, flexibility, and architecture. In this study, an experiment creating the same type of program with the help of different programming paradigms is made to compare the performance of the two. Some additional up- and downsides of the paradigms are also mentioned

Abstract:

Este trabalho descreve o desenvolvimento de uma estrutura lógica de software para o controle do CAVE do LNCC e sua utilização na visualização de dados biológicos. Configuramos e adaptamos o framework InstantReality para fazer funcionar todos os componentes singulares do CAVE do LNCC ( uma parede não ortogonal, duas paredes com cinco lados, projetores convencionais, entre outros ) por meio de uma tecnologia emergente, o X3D, usado para distribuir conteúdo 3D multimídia pela Internet. Propomos um processo para o rápido desenvolvimento, recorrendo ou não a uma linguagem de programação, de aplicações para visualização de dados biológicos, tais como: descrição geométrica de parte do sistema cardiovascular humano, de parte de uma larva, visualização de modelos de proteínas e capsídios de vírus. Apresentamos questões importantes na visualização de superfícies complexas, como a importância do modelo de iluminação utilizado e descrevemos a implementação de um modelos de iluminação em GPU. Adicionalmente, justificamos o emprego da Realidade Virtual como ferramenta valiosa para a visualização em bioinformática, e mesmo na biologia. Finalmente, avaliamos a eficiência geral do CAVE e de cada componente,através dos resultados obtidos na visualização de cenários temáticos de interesse biológico. Identificamos possíveis problemas e sugerimos opções para uma melhoria geral do desempenho.
This work describes the development of a software structure that currently controls the CAVE at LNCC, as well as its use for biological data visualization. This work also includes the adaptation and configuration of the InstantReality framework considering all particularities of the CAVE built at LNCC, which amongst other things does not have square walls all around (two walls have a particular shape). In order to accompish this task we make use of the emerging X3D technology. This work also proposes a process for fast development of biological data visualization. Such process has been used to develop a series of sample applications, which included geometric description of parts of the human cardiovascular system as well as other structures such as parts of worms and other creatures, visualization of proteine models and virus envelops both relying or not on some programming language. This work also introduces important aspects of complex surface visualization and describes the implementation of a GPU based ilumination model. Additionally, some justifications are presented regarding the use of Virtual Reality as a tool for bioinformatics visuzalization or biologic applications. Finally, this work evaluates the CAVE prototype, considering each of its components, in the light of the results achieved in the biologic visualization applications developed. Problems are identified and further improvements are proposed.

Abstract:

CRM Treasury Systems AB is one of the Nordic Countries’ leading companies within treasury management. Their main product CRM Finance is a software program for financial administrators with roots back to the early 90s. Computer usage and software has changed considerably since then and the company is currently considering choosing a new technology to base future products upon. In this thesis Oracle ADF, Microsoft Lightswitch beta 1 and Silverlight with WCF RIA Services, are compared in order to select a suitable technology to base future applications on. The frameworks are used to implement a simple application with a small number of screens displaying database data in order to get to know the frameworks and capture the time required to get started. After the basic applications have been implemented in all the three frameworks and evaluated it is decided to continue by implementing a number of more advanced authorization and internationalization scenarios. It is decided to continue with only two of the selected frameworks due to lack of time once the simple application has been implemented successfully. Lightswitch beta 1 is chosen for discontinuation due to an uncertain future for the application as it is the first public available beta of the product. Based on the experience from the implementations performed, the time required for them as well as how the platforms fit the company’s requirements the .NET platform with Silverlight + WCF RIA Services is recommended as the base for future applications.
