Hoje em dia, o uso de dispositivos móveis se tornou bastante popular e criou maneiras diferentes de interação com sua interface sensível ao toque. Aplicações de visualização científica possuem um potencial muito grande de desfrutar dessas novas formas de interação, contudo o poder de processamento dos dispositivos móveis ainda não é suficiente para renderizar e-ou tratar o grande volume de dados que esse tipo de aplicação requer. Propomos um framework, seguindo um modelo cliente-servidor, que permite a utilização de dispositivos móveis para visualização e manipulação colaborativa de aplicações de visualização científica. No papel de servidor, a aplicação científica faz uso de uma biblioteca para compactar e enviar as imagens renderizadas para os clientes e também para tratar os eventos recebidos. No papel de cliente, está um aplicativo multiplataforma (iOS-Android) rodando nos dispositivos móveis, que interpreta os gestos de toque e exibe as imagens recebidas via rede Wi-Fi. O mesmo aplicativo é capaz de conectar em qualquer servidor, pois constrói a interface baseada numa descrição em Lua que o servidor fornece. Por fim, o framework proposto é avaliado em dois aplicativos industriais: Geresim e 3DReplay.
Nowadays, mobile devices have become very popular bringing new ways of interaction with their touch-based interface. Scientific visualization applications have a great potential to take advantage of this new kind of interaction, but the processing capabilities of mobile devices are still not enough to render or process the amount of data this type of application requires. We propose a framework, working as a client-server model, which allows the use of mobile devices to collaboratively visualize and manipulate scientific visualization applications. In the server role, the scientific application uses a library to compress and send rendered images to clients and also to process received events. In the client role, there is a multiplatform application (iOS-Android) running on mobile devices, which interpret touch gestures and show the images received through Wi-Fi network. The same application is able to connect in any server, since it builds its interface from a description in Lua language supplied by the server. Lastly, we evaluate the proposed framework with two industrial applications: Geresim e 3DReplay.

Full textAbstract:
Efficient methods for rapid evaluation of television (TV) interaction devices are missing. This thesis presents how the Cognitive Walkthrough method can be modified to suit the demands of engineers in a development process. Moreover, the thesis also investigates how Personas can be applied to support the Cognitive Walkthrough method. The Modified Cognitive Walkthrough method was applied and tested in an actual development project on remote control design. The study suggests that the method can detect usability problems on TV interaction devices at an early stage of development. Further, the results indicate that it is easy to understand the method and apply it as part of the engineering practices.

Full textAbstract:
In this thesis study, it is aimed to improve the performance of an Internet-based teleoperation system enabling the remote operation of a 6 DOF industrial robot. In order to improve the safety and efficiency of the teleoperation, stability and synchronization (hand-eye coordination) are considered.
The selected communication medium between the human operator and remote robot is the Internet. The variable time delays and nondeterministic characteristics of the Internet may lead to instability of the teleoperation system. Considering the disturbing effects of the Internet onto the transmission, an event-based control approach is used in order to improve the stability of the teleoperation system. Besides, a visual feedback system is developed and a force-feedback mouse is designed in order to improve synchronization between the human operator and robot during the command generation according to the feedback obtained from the control system. A client-server software application is developed to interface the human operator with remote environment.
It is observed that, using the event-based control approach in the operation makes the teleoperation stable and improves the synchronization ability. Implementation of visual feedback and force-feedback mouse to the teleoperation system improves the human operator&rsquos ability to perform remote operation.

Full textAbstract:
Haptic devices allow a human to interact physically with a remote or virtual environment by providing tactile feedback to the user. In general haptic devices can be classified in two groups according to the energetic nature of their actuators. Devices using electric motors, pneumatic or hydraulic cylinders or other similar actuators that can add energy to the system are considered "active." Devices using brakes, clutches or other passive actuators are considered "passive" haptic devices. The research presented here focuses on the use of passive haptic devices used during teleoperation, the remote control of a "slave" device by the haptic "master" device. An actuation scheme as well as three different control methods is developed for providing the user with haptic feedback. As a final step, the effectiveness of the controllers is compared to that of a commercially available active haptic device. Twenty subjects provide data that shows the usefulness of the passive device in three typical teleoperation tasks.

Thesis (MScEng) Stellenbosch University, 2014ENGLISH ABSTRACT: Teleoperation as a field has seen much change since its inception in the early 1940s with Dr. Raymond Goertz producing the first teleoperation system for manipulating radioactive materials. With advances in core and supporting technologies, the systems have grown in complexity and capability, allowing users to perform tasks anywhere in the world irrespective of physical distance. The feasibility of such systems has increased as the drive for use of telepresence robots, exploration robots as in space exploration, search and rescue robots and military systems such as UAVs and UGVs gain popularity. This prompted the development of a proof of concept modular, user centred telerobotic system. The current project is the second iteration in the development process. Teleoperation and more specifically telerobotic systems pose a challenge for many system developers. This may be a result of complexity or the wide assortment of knowledge areas that developers must master in order to deliver the final system. Developers have to balance system usability, user requirements, technical design and performance requirements. Several developmental process models are considered in context of Engineering Management (EM). A larger Systems Engineering developmental process is used, with focus on the primary and supportive EM components. The author used a hybrid developmental model that is user focussed in its approach, the User-Centred Systems Design (UCSD) methodology was adopted as the primary model for application within the two distinct developmental categories. The first category hardware and system integration utilised the UCSD model as is. The second - Software development - relied on the use of agile models, rapid application development (RAD) and extreme programming (XP) were discussed with XP being chosen as it could easily incorporate UCSD principles in its development process. Hardware systems development consisted of mechanical design of end-effectors, configuration management and design, as well as haptic and visual feedback systems design for the overall physical system. Also included is the physical interface design of the input (master) cell. Further software development was broken into, three sections, the first and most important was the graphical user interface, haptic control system with kinematic model and video feedback control. The force following and matching characteristics of the system were tested and were found to show an improvement over the previous implementation. The force magnitude error at steady state was reduced by 10%. While there was a dramatic improvement in system response, the rise time was reduced by a factor 10. The system did however show a decrease in angular accuracy, which was attributed to control system limitations. Further human-factor analysis experiments were conducted to test the system in two typical use-case scenarios. The first was a planar experiment and the second a 3D placement task. The factors of interest identified were field-of-view, feedback vision mode, and input modality. Heuristic performance indicators such as time-to-completion and number of collisions for a given task were measured. System performance was only showed significant improvement when used with haptic control. This shows that the research into haptic control systems will prove to be valuable in producing usable systems. The vision factor analysis failed to yield significant results, although they were useful in the qualitative systems analysis. The feedback from post-experimentation questionnaires showed that users prefer the Point of View as a field of view and 2D viewing over 3D viewing, while the haptic input modality was preferred. The results from the technical verification process can be used in conjunction with insights gained from user preference and human-factor analysis to provide guidance for future telerobotic systems development at Stellenbosch University.
AFRIKAANSE OPSOMMING: Telewerksverigting as ’n gebied het al vele veranderinge ondergaan vandat die eerste stelsels deur Dr. Raymond Goertz geimplementeer was in die vroeë 1940s vir die hantering van radioaktiewe materiale. Met vordering in kern en ondersteunende tegnologieë, het die telewerksverigtingstelsels toegeneem in kompleksiteit asook gevorder in vermoeënsvaardigheid, wat gebruikers in staat stel om take te verrig vanuit enige plek op aarde, ongeag die fisiese afstand wat die gebruiker en die werksarea skei. Die lewensvatbaarheid van hierdie stelsels het ook toegeneem weens die belangstelling in teleteenwoordigheidrobotte, ruimtevaardige-robotte, reddings-robotte en militêre-robotte soos onbemandelug- voertuie (OLV) en onbemande-grond-voertuie(OGV). As gevolg van die belangstelling in telerobotiese stelsels is die ontwikkeling van ’n modulêre, gebruikers-gesentreerde telewerksverigting stelsel onderneem. Die huidige projek is ’n tweede iterasie hiervan. Telewerksverigting, en meer spesifiek, telerobotika stelsels ontwikelling, vereis dat stelselontwikkelaars ’n verskeidenheid kennisareas bemeester. Die ontwikkelaar moet ’n belans vind tussen gebruiker vereistes, bruikbaarheid asook tegniese ontwerp en prestasie vereistes. Menigde ontwikkelingsproses modelle is oorweeg en behandel in die konteks van Ingenieursbestuur (IB). ’n Stelselsontwikkeling proses is gevolg met ’n fokus op primêre en ondersteunende IB komponente. ’n Gemengde ontwikkeling is toegepass tot die projek wat die gebruiker as ’n hoof komponent van die stelsel in ag neem. Die oorhoofse ontwikkelingsmodel is die User-centred Systems Design (UCSD) proses, wat vir beide hardeware en sagteware ontwikkeling gebruik is. Vir die hardeware ontwikkeling is die UCSD toegepas soos dit uiteengesit is in die literatuur. Die sagteware ontwikkeling is voltooi met behulp van ratse metodes, “Rapid Application Development” RAD en “Extreme Programming” (XP) was oorweeg en XP was gekies as ontwikkelingsmodel. XP was die natuurlike keuse weens die gemak waarmee UCSD metodes en prinsiepe kon geinkorporeer word in die ontwikkelings proses. Hardeware onwikkeling het bestaan uit meganiese ontwerp, manipulasiegereedskap ontwerp, konfigurasie bestuur en ontwikkeling asook haptiese en visueleterugvoer stelselsontwerp van die fisiese stelsel insluitend die fisiese koppelvlakontwerp van die meester sel. Verder is sagtewareontwerp opgedeel in ’n haptiesebeheerstel met ’n kinematiese model ontwikkeling, videoterugvoerbeheer en gebruikersintervlak ontwerp. Die vermoëe van die stelsel om krag insette na te boots was verbeter met ’n gestadigde verbetering van 10%. Die reaksietyd van die stelsel is verbeter met ’n faktor van 10. Die stelsel het ’n verswakking getoon in die algehele hoekakkuraatheid, die oorsprong van die verswakking kan aan die beheerstelsel teogeken word. Verdere menslikefaktoranalise eksperimente is voltooi om die stelsel in twee tipiese gebruikgeval scenario’s te toets. Die eerste, ’n platvlak-eksperiment en die tweede ’n 3D plasingingstaak eksperiment. Die faktore van belang is ïdentifiseer as, visie-veld, terugvoervisie modus en insette modaliteit. Heuristiese prestasie-aanwysers soos tyd-tot-voltooiing en die aantal botsings vir ’n gegewe taak is gemeet. Stelselprestasie het slegs aansienlike verbetering getoon wanneer die stelsel met die haptiesebeheer modus bedryf word. Die visiefaktor ontleding het geen noemenswaardige resultate opgelewer nie. Terugvoervorms was na elke eksperiment voltooi. Vraelyste het getoon dat gebruikers die oogpunt van ’n lae hoek en 2D video oor 3D video verkies, terwyl die haptic beheer modaliteit verkies word.

Thesis (MEng)--Stellenbosch University, 2014.ENGLISH ABSTRACT: The fairly recent introduction of low-cost depth sensors such as Microsoft’s Xbox Kinect has encouraged a large amount of research on the use of depth sensors for many common Computer Vision problems. Depth images are advantageous over normal colour images because of how easily objects in a scene can be segregated in real-time. Microsoft used the depth images from the Kinect to successfully separate multiple users and track various larger body joints, but has difficulty tracking smaller joints such as those of the fingers. This is a result of the low resolution and noisy nature of the depth images produced by the Kinect. The objective of this project is to use the depth images produced by the Kinect to remotely track the user’s hands and to recognise the static hand poses in real-time. Such a system would make it possible to control an electronic device from a distance without the use of a remote control. It can be used to control computer systems during computer aided presentations, translate sign language and to provide more hygienic control devices in clean rooms such as operating theatres and electronic laboratories. The proposed system uses the open-source OpenNI framework to retrieve the depth images from the Kinect and to track the user’s hands. Random Decision Forests are trained using computer generated depth images of various hand poses and used to classify the hand regions from a depth image. The region images are processed using a Mean-Shift based joint estimator to find the 3D joint coordinates. These coordinates are finally used to classify the static hand pose using a Support Vector Machine trained using the libSVM library. The system achieves a final accuracy of 95.61% when tested against synthetic data and 81.35% when tested against real world data.
AFRIKAANSE OPSOMMING: Die onlangse bekendstelling van lae-koste diepte sensors soos Microsoft se Xbox Kinect het groot belangstelling opgewek in navorsing oor die gebruik van die diepte sensors vir algemene Rekenaarvisie probleme. Diepte beelde maak dit baie eenvoudig om intyds verskillende voorwerpe in ’n toneel van mekaar te skei. Microsoft het diepte beelde van die Kinect gebruik om verskeie persone en hul ledemate suksesvol te volg. Dit kan egter nie kleiner ledemate soos die vingers volg nie as gevolg van die lae resolusie en voorkoms van geraas in die beelde. Die doel van hierdie projek is om die diepte beelde (verkry vanaf die Kinect) te gebruik om intyds ’n gebruiker se hande te volg oor ’n afstand en die statiese handgebare te herken. So ’n stelsel sal dit moontlik maak om elektroniese toestelle oor ’n afstand te kan beheer sonder die gebruik van ’n afstandsbeheerder. Dit kan gebruik word om rekenaarstelsels te beheer gedurende rekenaargesteunde aanbiedings, vir die vertaling van vingertaal en kan ook gebruik word as higiëniese, tasvrye beheer toestelle in skoonkamers soos operasieteaters en elektroniese laboratoriums. Die voorgestelde stelsel maak gebruik van die oopbron OpenNI raamwerk om die diepte beelde vanaf die Kinect te lees en die gebruiker se hande te volg. Lukrake Besluitnemingswoude ("Random Decision Forests") is opgelei met behulp van rekenaar gegenereerde diepte beelde van verskeie handgebare en word gebruik om die verskeie handdele vanaf ’n diepte beeld te klassifiseer. Die 3D koördinate van die hand ledemate word dan verkry deur gebruik te maak van ’n Gemiddelde-Afset gebaseerde ledemaat herkenner. Hierdie koördinate word dan gebruik om die statiese handgebaar te klassifiseer met behulp van ’n Steun-Vektor Masjien ("Support Vector Machine"), opgelei met behulp van die libSVM biblioteek. Die stelsel behaal ’n finale akkuraatheid van 95.61% wanneer dit getoets word teen sintetiese data en 81.35% wanneer getoets word teen werklike data.

Full textAbstract:
The purpose of this thesis is to develop a remote control application for personal computers. This application will have two devices implied, the computer to be controlled and a small portable device that will be used as remote controller.
In this specific case, the portable device picked is the Nintendo DS, for reasons discussed later in this document that make this device interesting as a remote controller.
The application should allow the final user to create his own set of remote controllers for any computer application he wants to control, and also, to define the commands the application should perform. This makes the developed solution a full customizable universal remote controlling application.
The first step taken was to do a small research about what kind of devices and software are present actually for remote control applications, so the differences, advantages and disadvantages of using the Nintendo DS will be shown. Then the developed solution will be explained and tested, controlling some computer applications under different scenarios.

Full textAbstract:
A few studies have examined the effects of a remote control tactile device (RCT) as an unobtrusive prompting method used to promote skills such as verbal initiations and play behaviors in children with autism. To date, however, no published studies have investigated the effects of the RCT as a consequence to increase and maintain conversation skills. This study was designed to determine whether the RCT, in conjunction with common training techniques (i.e. roleplays, visual feedback, and sibling coaching), could be used as a discrete and unobtrusive feedback system to promote conversation skills in high functioning children with autism. Results found that the RCT and training packages were effective in initially increasing rates of target responses. The effects however, did not always maintain with a return to baseline. Programming "naturally" maintaining communities of reinforcement was found to be a critical factor in the maintenance of the conversational responses.

Full textAbstract:
Context. Both smartphones and PC games are increasingly commonplace nowadays. There are more and more people who own smartphones and – at the same time – like playing video games. Since the smartphones are becoming widely affordable and offer more and more advanced features (such as multi-touch screens, a variety of sensors, vibration feedback, and others), it is justifiable to study their potential in new application areas. The aim of this thesis is to adapt the smartphone for the use as a game controller in PC racing games and evaluate this solution taking into account such aspects as race results and user experience. Objectives. To this end, two applications were developed - a game controller application for Android‑based smartphones (i.e. the client application) and a PC server application. The applications support a selected open-source PC racing game called SuperTuxKart. The evaluation of the smartphone encompasses both race results (whether the smartphone enables players to achieve comparable results to the keyboard – a standard game controller) and user experience (whether this game controller may be satisfying to players). Methods. An experiment was conducted where 20 participants controlled the SuperTuxKart game using first the smartphone, and then the keyboard or vice versa. The experiment was followed by a questionnaire-based survey of the user experience. Results. The experiment results indicate that the smartphone may achieve results which are comparable to those achieved by the keyboard. The race times corresponding to the smartphone were somewhat longer than those obtained with the keyboard, but the average relative difference was below 18%. The questionnaire results show that more than half of the participants enjoyed the smartphone more than the keyboard, despite the fact that the smartphone turned out to be a more challenging game controller for many players and did not provide so good control of the racing game as the keyboard. Conclusions. Overall, this study shows that the smartphone has a potential to be a suitable, satisfying and enjoyable controller for PC racing games.

Full textAbstract:
Several aesthetic, health, and plumbing quality issues can arise during new construction or renovation of premise plumbing. There has been little research done on many of these concerns and therefore few guidelines or regulations are in place to protect the health of the consumer or the integrity of the plumbing infrastructure. This work examines common construction practices including: 1) effect of residual construction debris, 2) shock chlorination of new plumbing lines, and 3) lead leaching propensity of new brass ball valves.
During installation of plumbing systems, residual chemicals and debris including copper brass particles and flux, can be left in plumbing lines following construction and installation. This debris is considered undesirable from health, aesthetic, and corrosion perspectives. Soldering flux is of particular concern due to its corrosive nature. Experiments were conducted to determine the effects of residual solder flux, PVC glue, and metallic debris and to quantify flushing velocities and durations to effectively remove them from a new plumbing system. A flushing velocity of 3 fps for 30 minutes is needed to remove water soluble flux, while petroleum based flux still persists after extensive flushing at 7 fps.
Currently a practice known as shock chlorination, whereby super chlorinated water is used for disinfection, is used in water mains after installation or repair as specified in the ANSI/AWWA C651 Standard. This practice is now starting to be required by some building codes in premise plumbing for new construction. Water mains are typically made of concrete where as premise plumbing using copper or PVC piping. Copper pipe is susceptible to attack by high chlorine, and this reaction will also remove the chlorine residual. There is concern about potential damage to copper from free chlorine and that in some systems targeted residuals of chlorine might not be obtained. Experiments did not detect serious damage to copper pipe, but in some waters it was not possible to meet targeted residual levels of chlorine. The addition of orthophosphate corrosion inhibitor or adjustment of pH can sometimes reduce the chlorine decay rate.
Extremely high and persistent lead leaching in a brand new building at the University of North Carolina (UNC) traced to leaded bronze ball valves, prompted an extensive forensic evaluation how existing standards (National Sanitation Foundation Section 8) could allow for installation of products that could create a human health hazard due to high lead. Diffusion of lead from within the device to water in the pipe, high velocity, microbial activity and other factors caused more leaching in practice than would be expected based on NSF testing and normalization factors applied to certify a valve as safe. Moreover, use of flux during soldering of joints, increased lead leaching by orders of magnitude relative to results of NSF testing without flux.Master of Science

Full textAbstract:
Despite increased awareness of threats against Critical Infrastructure (CI), securing of Supervisory Control and Data Acquisition (SCADA) systems remains incomplete. The majority of research focuses on preventative measures such as improving communication protocols and implementing security policies. New attempts are being made to use commercial Intrusion Detection System (IDS) software to protect SCADA systems. These have limited effectiveness because the ability to detect specific threats requires the context of the SCADA system. SCADA context is defined as any information that can be used to characterise the current status and function of the SCADA system. In this thesis the standard IDS model will be used with the varying SCADA data sources to provide SCADA context to a signature and anomaly detection engine. A novel addition to enhance the IDS model will be to use the SCADA data sources to simulate the remote SCADA site. The data resulting from the simulation is used by the IDS to make behavioural comparison between the real and simulated SCADA site. To evaluate the enhanced IDS model the specific context of a water and wastewater system is used to develop a prototype. Using this context it was found that the inflow between sites has similar diurnal characteristic to network traffic. This introduced the idea of using inflow data to detect abnormal behaviour for a remote wastewater site. Several experiments are proposed to validate the prototype using data from a real SCADA site. Initial results show good promise for detecting abnormal behaviour and specific threats against water and wastewater SCADA systems.

De nos jours, le maintien de l'asepsie dans la salle d'opération est vital pour la limitation de la transmission d'infections nosocomiales au patient lors de l'opération. Des mesures d'asepsie drastiques ont pour but de préserver la zone stérile de tout agent infectieux.Elles interdisent actuellement au chirurgien d'interagir avec les équipements non-stériles du bloc.Le chirurgien opérant souhaiterait cependant disposer d'un contrôle direct sur certains équipements spécifiques du bloc dans des situations données sans enfreindre ces mesures.Les travaux présentés dans cette thèse concernent le développement d'une Interface Homme-Machine permettant la commande gestuelle sans contact, et donc sans transmission d'agents infectieux, de tels équipements.Dans la continuité des travaux existants dans la littérature, une chaîne de traitement basée sur des techniques de vision informatique et un prototype de caméra portée par l'utilisateur ont ainsi été développés pour atteindre ces objectifs. Ce document présente les études comparatives menées sur des algorithmes issus de la littérature afin de sélectionner les plus aptes à être employés dans la chaîne logicielle. Un descripteur géométrique dédié aux mains est introduit, et des approches coopératives sont investiguées sur les étapes de localisation de la main et de classification de la posture prise.Les performances de la chaîne de traitement ainsi créée sont évaluées dans différentes situations à l'aide de bases d'images et de vidéos extensives acquises dans des conditions proches de celles du bloc opératoire, ainsi que sur des images synthétiques réalisées sur un modèle virtuel de main créé ad hoc.Un démonstrateur composé de la chaîne de traitement développée et d'un prototype de caméra frontale permet, associé à une simulation de bras-support d'éclairage opératoire, d'illustrer les possibilités ouvertes par le système développé au cours de cette thèseAsepsis preservation in operating rooms is nowadays compulsory for avoiding the spread of hospital-acquired diseases to patients during surgeries. Drastic asepsis measures aim at preserving the sterile area of the operating room from infective agents.These measures forbid surgeons from interacting with non-sterile devices. Surgeons wish nonetheless having direct control over some of these devices.The works presented in this thesis relate to the development of a Human-Computer Interface enabling remote, hence without transmission of infective agents, non-contact control over such devices.Following on from previous authors' works in the literature, an image processing chain based on computer vision techniques and a wearable camera prototype have been developed in order to achieve these goals.This document presents the comparative studies led with algorithms issued from the literature with the aim of selecting the most suitable for using in the processing chain. A dedicated geometry-based hand descriptor is introduced, and cooperative approaches are investigated in relation with the hand localization and posture classification steps.The performance achieved by the processing chain in various situations are quantified using extensive picture and video databases acquired in conditions close to those of the operating room. Synthetic pictures created using an ad hoc virtual model of the hand are used as well for this evaluation.A demonstrator composed of the developed processing chain, a wearable camera prototype and a surgical lighting arm simulator enables the illustration of the possiblities offered by the system developed during this thesis

Full textAbstract:
Magnetic Resonance Imaging (MRI) provides unique advantages such as superior soft tissue contrast, true multiplanar imaging, variable contrast mechanisms, measurement of temperature changes, perfusion and diffusion, and no ionizing radiation. Despite considerable research efforts in the field of interventional MRI, numerous challenges remain including restricted access to the patient, high acoustic noise and a shortage of MRI-safe devices. Novel methods and devices are presented in this thesis with the primary objective of enabling effective MRI-guided interventions, particularly abdominal needle and common catheter-based endovascular interventions. Firstly, a set of MRI-safe devices (guidewires, micro guidewires, catheters and micro catheters) were developed with passive or inductively coupling resonant markers for MRI visualisation. Secondly, a method was implemented for wireless tracking and dynamic guidance of instruments. Thirdly, a framework of technologies was developed for in-room display, wireless MRI remote control and multi-user communication along with a dedicated user interface and imaging protocol. These implementations were assessed in regards to MRI-safety, performance and usability and evaluated for MRI-guided liver biopsies, balloon angioplasty procedures and also for mechanical thrombolysis. Flow phantoms, Thiel soft-embalmed human cadavers with partially re-established perfusion and a porcine model were used for in vitro, ex vivo and in vivo validation, respectively. The results demonstrate that these interventions are experimentally feasible and practical when using the presented developments: automated device tracking and equipment designed for MRI-guided interventions streamlined procedural workflow. Specifically, it was shown that fast and accurate needle placements along complex trajectories were feasible using a wireless interactive display and control device with a dedicated user interface for interventions. Moreover, safe and efficacious balloon angioplasties of the iliac artery were practical using the described framework of technologies along with a dedicated MRI protocol. Finally, it was demonstrated that these developments could be adapted and applied to MRI-guided endovascular mechanical thrombolysis of the middle cerebral artery. The technologies, described in this thesis have been shown to overcome many of the present limitations and should therefore be useful for enabling MRI-guided interventions while not further constraining the operating physician in an already complex environment. Nevertheless, it is acknowledged that many crucial issues remain to be solved in the field of iMRI and in the context of the presented research. In particular further device optimisations, improvements of the tracking implementation along with further in vivo evaluations are required before moving towards clinical evaluation. This thesis sets the groundwork for moving ahead with the eventual clinical realisation of optimised MRI-guided interventions.

Based on Hierachy Transformation Method（HTM）, a supervisor on Manufacturing Execution System（MES） architecture is designed and implemented for a flexible conveyor system. In this architecture, the supervisor gives commands to a Virtual Manufacturing System（VMS）which maps onto a Physical Manufacturing System（PMS）via communication network for multi- user remote control. The supervisor is designed through the concept of segment resources. The intended behavior of each conveyor segment is analyzed, designed, verified, and implemented as four stages. At functional requirement stage, the material flows through each conveyor segment are specified. At designed stage, the information flows are designed to control material flows. At verification stage, the liveness of the controlled conveyor is verified by transformed Petri net models. At implementation stage, the verified Petri net models are transformed into sets of rules for real time control. Also the implementation of supervisors for the conveyor system at Production Automation Center, NCTU,successfully demonstrates the concept of segment resources, supervisor design for MES, and remote manufacturing control.

Taiwan is the leading country manufacturing a lot of hardware such as personal commuter, wire and wireless communication device, consumable electronic, information appliance, etc. In Taiwan, mobile phone and PDA are universal and the infrastructures of wire and wireless networks are also quite complete. But the applications to use these devices and infrastructures are not enough oppositely. Beside, people aspire to acquire any information content or monitor and control any devices at any time and anywhere. Therefore, we think to integrate the handheld devices such as mobile phone and PDA and WiFi 802.11, GPRS or 3G networks and the software technology like Java programming language to implement the dream of mobile and wireless monitoring and control. Due to the characteristic of platform independent and strong abilities in the network and multimedia, we select the Java programming language to integrate above-mentioned platforms. We adopt Java 2 SE, Java 2 ME and Personal Java individually to program the Server and Client applications for each PC, mobile phone and PDA. Nowadays, the technology of hardware is very progressive, but the software still needs us to explore. In the future, the limitation will not be the technology whether it is available or not. The limitation is if you have the ability of integration and any rich idea.

This dissertation describes the development and implementation of techniques to enhance
the accuracy of low-complexity lters, making them suitable for remote control devices
in consumer electronics. The evolution veri ed in the last years, on multimedia contents,
available for consumers in Smart TVs and set-top-boxes, is not raising the expected
interest from users, and one of the pointed reasons for this nding is the user interface.
Although most current pointing devices rely on relative rotation increments, absolute
orientation allows for a more intuitive use and interaction. This possibility is explored in
this work as well as the interaction with multimedia contents through gestures.
Classical accurate fusion algorithms are computationally intensive, therefore their implementation
in low-energy consumption devices is a challenging task. To tackle this
problem, a performance study was carried, comparing a relevant set of professional commercial
of-the-shelf units, with the developed low-complexity lters in state-of-the-art
Magnetic, Angular Rate, Gravity (MARG) sensors. Part of the performance evaluation
tests are carried out under harsh conditions to observe the algorithms response in a nontrivial
environment. The results demonstrate that the implementation of low-complexity
lters using low-cost sensors, can provide an acceptable accuracy in comparison with the
more complex units/ lters. These results pave the way for faster adoption of absolute
orientation-based pointing devices in interactive multimedia applications, which includes
hand-held, battery-operated devices.

In this thesis, the sensing properties of the chlorine and the pH sensing devices were discussed, and the chlorine and pH sensing devices applied to wireless measurement system and water quality monitoring system. The pH sensing membrane (ruthenium dioxide (RuO2)) was deposited on the silicon substrate by radio frequency (R. F.) sputtering system. The selective membrane of chlorine ion was prepared on the pH sensing membrane thin film by spin coating method. As well as, the sensing performance of the chlorine and pH sensing device with different manufacturing conditions were analyzed by using voltage-time system (V-T system) and electrochemical impedance spectroscopy (EIS). The quality of sensing device was measured by EIS before measurement, and the sensitivity and linearity of the sensing device was measured by V-T measurement system. The response time of the chlorine and pH sensing devices were less than 30 s and 10 s, respectively. The sensitivity and linearity of the pH sensing device were 55.27 mV/pH and 0.999, respectively. The sensitivity and linearity of the chlorine sensing device were 10.04 mV/ppm and 0.996 in sodium chloride (NaCl) solution, respectively. The sensitivity and linearity of the chlorine sensing device were 15.33 mV/ppm and 0.990 in sodium hypochlorite (NaClO) solution, respectively. Moreover, the lifetime of the chlorine sensing device was immersed at least 14 days in NaCl or NaClO solutions; the lifetime of the pH sensing device was immersed at least 15 days in pH buffer solutions. According to the experimental results, chlorine and pH sensing devices can be applied to water quality monitoring system with wireless measurement system for real-time measurement and long-term measurement.

This project report describes the work carried out to design and evaluate new
interfaces for media consumption in Smart TVs. The main goal is the study of the
different technologies that can integrate a new generation of remote controls, and the
development of prototypes (interfaces) that allow to connect all selected technologies
in order to find a combination that improves the users quality of experience (QoE).
Traditionally, the use of remote controls for television control uses only mechanical
buttons to execute different tasks but, due to constant technological progress,
an evolution is underway in the way users consume television content, moving
from traditional passive visualization of contents to interactive forms. In this
new interactive forms the user increasingly uses actions, adapts and interacts with
multimedia content, services on demand and applications that support multiple users
(games, social networks, etc). To keep up with these developments, it is necessary
to add features to the conventional remote controls to enable a dynamic control,
fast and accurate text input methods, and haptic feedback that is appropriate for
the tasks that users need to perform.
Two interfaces were developed integrating different haptic technologies that would
provide the features mentioned above (dynamic control, text input methods, and
haptic feedback). To assess the operation of the developed interfaces, tests were
performed with different users to obtain objective and subjective classifications. The
contribution of this work, was the integration of technologies that can improve the
users QoE when using a Smart Tvs/Boxes and collecting users satisfaction levels
regarding to the use of these technologies in remote controls. The tests show that
despite the large number of different haptic effects users preferred one for each type
of different technologies. Based on user rating, for the dynamic interaction case,
one technology has proved to be preferred. In the case of text input/editing, among
the various technologies, one of the technologies allows a fast text input with the
highest level of user satisfaction.

The issue of precision agriculture has received considerable critical attention. However, few studies to date have investigated variable-amount spraying device with dilution. The objectives of this research were to develop variable-amount device with dilution and examine its utility with liquid fertilizer. Using an Arduino-controlled hybrid system with Wi-Fi, the correlations between valve travel position and volumetric flowrate were calculated to determine the relationship of valve travel position and dilute factor. Results of this research revealed that a linear trend appear when the valve travel position is within 24% and 34% and the flowrate is within 0.17 L/min and 0.34 L/min, and also showed that dilution factor was highly accuracy within 1.5 and 3.0. Moreover, an app was developed so that users could assign the dilute factor and sent data via Wi-Fi. In conclusion, we have been successful in developing an accurate variable-amount spraying device with dilution and WiFi-controlled. This research expects in contribute to ongoing discussion about dilution in variable-amount application.

In this thesis, we use eigenvector method to capture the color of special object on the image retrieved by CCD. After processing with image recognition rules, the result is transmitted to remote servo motor to produce respective movement, and the goal of human machine interactive is achieved. The image tracking method used in this thesis is based on characteristic method; however, the method to obtain an object is different from characteristic method. Before sampling, the focus was to obtain appropriate RGB eigenvector. That is, if colored tag confirms with eigenvector, it is the target needed. Comparing with ordinary characteristic method, this method takes 0.0014 seconds more. But its credibility is increased and processing time needed afterward is reduced. This meets the design application for future research.

In practice, there are many jobs that are in highly dangerous and complicated environments, are limited by human force, or should be down by human knowledge with intelligence and experience. The most effective method is tackle the problems is to use the master-slave telerobotics with haptic behavior. Due to the fact that the master robot is maneuvered by the human arm and its dynamics and characteristics are always changed, the performance of the closed-loop system is not satisfied, and even to an unstable extent. One way to solve the problem is to incorporate the human dynamics into the closed-loop system such that the characteristic of the human can also be considered in the stability criteria. In order to include the human dynamics into the closed-loop, powered handlers must be used to transform the human force into electrical signals by force sensors. In addition, signals from the master side are run forward to the slave one by the haptic interface device and vice versa, such that the operator can feel the actual force feedback from the slave side just as she/he would from the real one. In this thesis, analysis and design of the telerobotics based on the haptic interface device for controlling the master slave robots and virtual reality (VR) for simulating the cutting clay system is proposed. The main components of the system include user interface, networking, actuators, and haptic interface simulated by the computer softwares. In order to guarantee the stability of the system, the Nyquist criterion and maximum modulus theorem are both used to find the stability bounds. By selecting a proper value ranged from the bounds, the satisfactory performance of the closed-loop system is also achieved. For controlling the cutting clay system, the slave robot and its environments are simulated by virtual reality that enables the operator to feel the actual force feedback from the virtual reality just as she/he would from the real environment. The haptic virtual system integrates the dynamics of the cutting tool and the virtual environment whereas the handle actuator consists of the dynamics of the handle and the operator in the physical side. It is shown that the proposed control scheme guarantees global stability of the system, with the output of the cutting tool approaching that of the handle if the ratios of the position and the force are selected. Experiments for an one dimensional master slave manipulator and a two dimensional master slave manipulator where the slave one is the cutting clay system and is simulated by the virtual reality are used to validate the theoretical developments.
