Abstract:

Interface designs are currently tested in a mixture of fidelities and media. So far, there is insufficient research to indicate what level of fidelity and media will produce the best feedback from users. This experiment compared user testing with low- and high-fidelity prototypes in both computer and paper media. Task-based user tests of sketched (low-fidelity) and HTML (high-fidelity) website prototypes were conducted in each medium, separating the testing medium from other factors of prototype fidelity. We found that low- and high-fidelity prototypes are equally good at uncovering usability

Abstract:

This study compared usability testing results found with low- and high-fidelity prototypes for mobile phones. The main objective is to obtain deep understanding of usability problems found with different prototyping methods. Three mobile phones from different manufactures were selected in the experiment. The usability level of the mobile phones was evaluated by participants who completed a questionnaire consisting of 13 usability factors. Incorporating the task-based complexity of the three mobile phones, significant differences in the usability evaluation for each individual factor were found

Abstract:

This study investigated the effect of prototype fidelity on the information obtained from a usability test with potential users of a software product. Users engaged in a series of structured tasks using one of three prototypes which emulated a Microsoft® Windows 95™ based library search computer system and which differed only in their fidelity (low = paper; medium = screen shots, high = interactive Visual Basic prototype). Results indicated there were no significant differences as a function of prototype in the number and severity of problems encountered nor in the subjective evaluation of the

Abstract:

This paper describes about the design and development of PToolkit prototype. We used both low and high fidelity prototype techniques for development of PToolkit prototype interactive application with expert user collaboration in the design iterative phases. Low fidelity prototype enables exploration for the general layout and information contents, whereas high fidelity prototype allows experimentation in providing experience for intended context and target user group. Both techniques has proved provide experiences in design context, thus allows an early reflection and design transformation.

Abstract:

A case is made for using low-fidelity prototypes early in the design phase of new services. The rationale for this is based upon (1) a model of how user interface designs progress and (2) a call to expediency. The design process is viewed as the successive application of constraints that serve to prune the space of all user interfaces. Some constraints are external (i.e., placed on the service by limits of technology or cost). Other constraints are derived by application of heuristic design principles. Even after these constraints have been applied, the design is still not fully constrained an

Abstract:

A number of techniques, grouped under the umbrella term of usability inspection, have been devised in recent years to help software developers focus more closely on the needs of end-users during the development of interactive applications. Central to the use of such methods is the question of how proposed designs can be tested before a complete system has been implemented. This paper discusses the role of high and low-fidelity prototypes used for this purpose in software development and proposes the use of a “variable-fidelity” prototype as an aid to the development of interactive robotic syst

Abstract:

A versatile measurement system for systematic testing and measurement of the evolution of theI-Vcharacteristic curves of photovoltaic panels or arrays (PV generators) is proposed in this paper. The measurement system uses a circuit solution based on DC-DC converters that involves several advantages relative to traditional methods: simple structure, scalability, fast response, and low cost. The measurement of the desired characteristics of PV generators includes high speed of response and high fidelity. The prototype system built is governed by a microcontroller, and experimental results prove

Abstract:

Background Typical solutions for improving discharge planning often rely on one-way communication mechanisms, static data entry into the electronic health record (EHR), or in-person meetings. Lack of timely and effective communication can adversely affect patients and their care teams. Objective Applying robust user-centered design strategies, we aimed to design an innovative EHR-based discharge readiness communication tool (the Discharge Today tool) to enable care teams to communicate any barriers to discharge, the status of patient discharge readiness, and patient discharge needs in real tim

<span> With the tremendous technological progress and the widespread use of a variety of technologies, we note how smart cities are providing services efficiently by using technologies. The aim of this project is to build a Smart Traffic Control System (STCS) to facilitate and optimize traffic flow, minimize traffic congestion, and reduce the waiting time by detecting the density on each street. This work has been carried on four phases. Firstly, collecting data by a questionnaire and we received 331 responses. Secondly, using Proteus simulation. Thirdly, building a low fidelity prototyp

Abstract:

Reading comprehension of technical texts is a very important skill that engineering students need to develop. One of the first encounters of engineering students with technical texts in English occurs in programming activities when using a C/C++ compiler, and errors are produced at compilation time. In this work, we present preliminary results of the design of serious games to assist reading comprehension of C compiling errors. We designed and evaluated low fidelity prototypes of games designed so that players can improve their reading comprehension skills at the micro-, and macro-level, i.e.

Background The German Biobank Alliance (GBA) aims to establish a cross-site biobank network. For this endeavor, the so-called Sample Locator, a federated search tool for biospecimens and related data, has been developed, forming the heart of its information technology (IT) infrastructure. Objective To ensure the sustainable use of such a tool, we included researchers as participants in an end user–based usability evaluation. Methods To develop a prototype ready for evaluation, we needed input from GBA IT experts. Thus, we conducted a 2-day workshop with 8 GBA IT team members. The focus was on

Electronic devices are high-demand commodities in today’s world, and such devices will continue increasing in popularity. Currently, batteries are implemented to provide power to these devices; however, the need for battery replacement, their cost, and the waste associated with battery disposal present a need for advances in self-powered technology. Energy harvesting technology has great potential to alleviate the drawbacks of batteries. In this work, a novel piezoelectret foam material is investigated for low-level vibration energy harvesting.

Vehicle driveability is one of the important attributes in range-extender electric vehicles due to the electric motor torque characteristics at low-speed events. Physical vehicle prototypes are typically used to validate and rectify vehicle driveability attributes. However, this can be expensive and require several design iterations. In this paper, a model-based energy method to assess vehicle driveability is presented based on high-fidelity 49 degree-of-freedom powertrain and vehicle systems.

Abstract:

Several heat-to-power conversion technologies are being proposed as suitable for waste-heat recovery (WHR) applications, including thermoelectric generators, hot-air (e.g., Ericsson or Stirling) engines and vapour-cycle engines such as steam or organic Rankine cycle (ORC) power systems. The latter technology has demonstrated the highest efficiencies at small and intermediate scales and low to medium heat-source temperatures and is considered a suitable option for WHR in relevant applications. However, ORC systems experience variations in performance at part-load or off-design conditions, which
