This thesis firstly presents the exploration of an engaging user interface and navigation design for local community mobile applications. Furthermore, it seeks for the best suitable tool for both rapid prototyping and production development. The research and content is structured based on design and creation research methodology which is a user-centric and iterative process. To evaluate the suggested interface design and the selected tool, an interactive prototype was developed in this thesis. The results argues that card-based user interface and navigation design has the potential to enhance user engagement. In addition, AngularJS as the selected tool is a suitable framework for rapid prototyping as well as production development.

This thesis argues for a new theory of medical humanities practice and research, known as Mind Interface Theory. It begins with the claim that Sigmund Freud expanded medical metaphysics considerably in "A General Introduction to Psychoanalysis," and that this expansion affords the possibility of thinking of the mind as a user interface. Capitalizing on this affordance, the work then introduces mind interface theory as one possible imagining of Freud's metaphysical system, separate from his well-known theory, psychoanalysis. More specifically, it uses his discussion of dreamwork to reveal reprocessing as mind interface's mechanism of healing, before utilizing this reprocessing principle to orient the medical humanities' research, providing a theoretical framework for increased collaboration between humanists and physicians and a foundation for two distinct modes of activist scholarship: product-based and process-based. / Master of Arts / This thesis participates in medical humanities scholarship by advocating for a specific theory of the field that stems from a reading of Sigmund Freud’s Introduction to Psychoanalysis, a brief series of lectures which were written down for public consumption. Instead of using psychoanalysis itself to form a theory of the medical humanities, my work abstracts the broader suppositions on which psychoanalytic interpretation is rooted. This broader framework I call Freud’s medical metaphysics and define as the assumptions about causation and disease which form the basis for his philosophy of medical treatment. In making this distinction, I can more ably build my own theory of a mind interface on the fact that the basic structure of the metaphysics advocated in the lectures implies a vision of the mind that can be likened to a modern user interface. Through conceiving of the mind in terms of a user interface, I use mind interface theory to frame treatment in such a way as to promote a humanist theory of healing. The purport of the method is that humanists can assist patients through helping them utilize signs, language, and symbols to reprocess their experience. The advocation of this method is then applied to current threads in medical humanities scholarship to suggest that efforts in the field would be best served if they were directed towards studying the artifacts of patient populations for narrative and rhetorical strategies which were effective with coping with a specific illness and fostering an environment where patients are encouraged to produce such artifacts.

The increasing popularity of the World Wide Web (WWW) has created a new market: Web access through television to accommodate those who either cannot afford existing hardware or are intimidated by computers. Current efforts to combine the WWW and television have targeted potential novice users. One of the approaches for creating a WWW browsing system that is both simple to use and inexpensive is the utilization of the existing cable system to provide Web access through television. Some unique characteristics of this browsing system are fast access to the Web, the use of nine buttons on a universal remote control, and an index structure for reaching Web sites. Since browsing the Web through television is relatively new, many interface issues need to be examined. The purpose of this research was to investigate potential user interface designs for this WWW browser and to evaluate the usability of the nine-button interface. Sixteen volunteers participated in the experiment and were asked to navigate to specific Web sites with two interface formats, five different system lag times (0.2, 0.7, 1.3, 2.0, and 3.0 seconds), and three feedback styles (active feedback, passive feedback and no feedback). Participants were prescreened for their experience with computers and browsing the Web. The experiment was conducted in a living room setting to simulate real life situations and participants were given a total of 42 tasks to complete throughout the experiment. Each task consisted of navigating through the tree structure with either one of the two interface formats until reaching a designated Web site. The number of errors committed and task completion times were recorded. In addition, participants were asked to rate the WWW browser system after each task as well as after the entire experiment. Participants preferred the 0.2 second system lag and the active feedback style. Overall, they committed fewer errors and took less time to complete tasks with the tabbing interface than with the one-to-one mapping interface. Experienced participants committed more errors than did the inexperienced ones. Increase of system lag time was determined to have a greater adverse effect on the tabbing interface than on the one-to-one mapping interface. / Master of Science

The purpose of this thesis is to explore and study the usability issues within Technical Data Management Systems (TDMS). The research has been conducted as a single case study at the gardening and landscape maintenance company Husqvarna. The inductive research led to conducting 10 interviews, 2 expert focus groups and a observational study. An artefact was produced during the research to emulate a potential system. During the research, the researchers identified ten heuristic usability issues within TDMS. Fur- thermore the functional and non-functional needs of Husqvarna have been identified. The artefact was created, based on existing usability guidelines, addressing the usability issues and the needs of Husqvarna. The artefact was used to answer if the applied guidelines have solved the identified usability issues. The conclusion was set, that the applied guidelines had solved the identified issues. With the research being conducted with a single case study, the result may lack generalisability. Future researchers are encouraged to conduct a multiple case study to further identify issues within the research area.

This thesis investigates embedded databases and graphical interfaces for the MicroBaseJ project. The project aim is the development of an integrated database and GUI user interface for a typical 3G, or 2.5G, mobile phone with Java MIDP2 capability. This includes methods for data acquisition, mobile data and information communication, data management, and remote user interface. Support of phone delivered informatics will require integrated server and networking infrastructure research and development to support effective and timely delivery of data for incorporation in mobile device-based informatics applications. A key research and development (R&D) challenge is to support effective and timely delivery of data for incorporation in mobile device-based informatics applications. Another important aspect of the project is determining how to develop efficient graphics for the small mobile screen. The research investigates and analyses the architecture of a mobile monitoring system. The project developed a generic solution that can be implemented in a number of commercial sectors, such as horticulture, building management and pollution/water management. The developed concept is tested using data relevant to the horticultural area of application. The system also addresses the main issues related to mobile monitoring, including real-time response, data integrity, solution cost, graphical presentation, and persistent storage capabilities of modern mobile devices. Four embedded databases based on J2ME have been investigated. Two of the four have been evaluated and analysed. The Insert function, Sequence Search, and Random Search of Perst List and RMS (Record Management System) databases have been tested. The size of the processed data was limited to 20,000 records when using the wireless toolkit simulator, and 11,000 records when using a mobile phone. Perst Lite reflects good performance and has out-performed RMS in all tests. User interface software such as J2ME Polish for mobile phones has been investigated. Custom J2ME class for graphical interface is developed. This provides the graphical presentation of the data collected from the sensors; including temperature, wind speed, wind direction, moisture, and leaf wetness. The graphical interface, bar charts, and line charts with trace ball for collected data have been designed and implemented. The embedded database performance and project performance have been investigated and analysed. The performances of Perst Lite and RMS are evaluated in terms of the insert, sequence search, and random search functions based on simulation and real devices. The record numbers vary from 1,000 to 20,000. The project performance contains data receiving and storage, and data presentation and configuration. The performance of data storage and configuration can be negated due to the running mode and the response time. Thus, data presenting performance is the key focus in this project. This performance was divided into the categories of initial, data search, data selection, and charting. The initial performance includes the initialisation of the project parameters, and the reaching of the welcome interface. Data search performance refers to the retrieval of the specified data from the embedded database, measured on 48 data points, which only can be presented on the mobile screen from the retrieved data. These four performance types are measured in thousands of record numbers, varying from 1,000 to 18,000 record numbers, with the retrieved data range varying from 1 day to 30 days.

<p>The aim of this thesis project is to create a user interface for a web based film production project management portal. This implies creating a site map and a functionality specification based on the needs of the people working in the film production industry. The project was made on account of The Chimney Pot, a post production company in Stockholm. For the scope of this project, the research was concentrated on the part of film production that concerns The Chimney Pot, i.e. the procedures that take place after a film has been recorded. The research also focused on people working in the area of Stockholm, even if their clients and customers in other areas of Sweden and abroad were indirectly included in order for the project portal to be a usable tool in projects where these people are involved. </p><p>Before any visible results can be seen in a web production project, a range of preparation steps needs to be taken. Planning is essential if the final product shall work properly. Extensive research has to be done into the industry. In order to make the product usable, the intended users, their requirements, work procedures and environment need to be examined. Only when there are substantial results and enough knowledge about the industry, the actual implementation can start. The first step is to make a functionality specification, next a site map should be produced and the technical architecture should be specified. These are the areas that are covered in this project, but there are also recommendations about how the further development should be made. Important aspects in the next phase are to create a budget, to put together a development team and to create a graphic user interface. In the whole process the issues of usability need to be considered, i.e. efficiency, flexibility, learnability and satisfaction. </p><p>The key requirements for the project portal turned out to be speed and effectiveness. The user interface was designed to be intuitive and to be shallow, which means that the user should be able to perform any task with the least amount of mouse clicks possible. Another intention with the produced user interface is for it to be clearly divided into the four main areas that could be extracted from the user requirements. They are planning, project details, communication and file sharing. Directly after logging on to the project portal, the user should get an overview of all these areas. Other important considerations were security, version control and seamlessness. These issues demand a thorough planning of the technical architecture and this thesis provides some useful tips for the further development of the technical specification.</p>

Museums can be perceived as stuffy and forbidding; web technologies can enable museums to expand access to their collections and counterbalance these perceptions. Museums are searching for new ways to communicate with the public to better make a case for their continued relevance in the digital information age. With the emergence of multitouch computing, other diverse forms of digital access and the popularization of the user experience, challenge museum design professionals to synthesize the information seeking experience that occurs on multiple computing platforms. As a means of addressing these issues, this Master’s Report summarizes the One Butterfly design project. The project's goal was to create a design for a multitouch interface for federated search of Smithsonian collections. This report describes the project’s three major phases. First, an idea for an interface was developed and designs based on that idea were captured and clarified. Second, a formal review of related research was undertaken to ground these designs in the museum informatics, user interface design, and multitouch interaction design literatures. Finally, the report concludes with a review and reflection on the designs and their underlying ideas in light of things learned in the previous phases. / text

The field of computer user interface design is rapidly changing and diversifying as new devices are developed every day. Technology has risen to become an integral part of life for people of all ages around the world. Modern life as we know it depends on computers, and understanding the interfaces through which we communicate with them is critically important in an increasingly digital age. The first part of this paper examines the technological origins and historical background driving the development of graphical user interfaces from its earliest incarnations to today. Hardware advancements and key turning points are presented and discussed. In the second part of this paper, skeuomorphism and flat design, two of the most common design trends today, are analyzed and explained. Finally, the future course of user interface is predicted based off of emergent technologies such as the Apple Watch, Google Glass, Microsoft HoloLens, and Microsoft PixelSense. Through understanding the roots and current state of computer user interface design, engineers, designers, and scientists can help us get the most out of our ever-changing world of advanced technology as it becomes further intertwined with our existence.

In the past decade and more than any time before, new technologies have been broadly applied in various fields of interaction between human and machine. Despite many functionality studies, yet, how such technologies should be evaluated within the context of human computer interaction research remains unclear. This research aims at proposing a mechanism to evaluate/predict the design of user interfaces with their interacting components. At the first level of analysis, an original concept extracts the usability results of components, such as effectiveness, efficiency, adjusted satisfaction, and overall acceptability, for comparison in the fields of interest. At the second level of analysis, another original concept defines new metrics based on the level of complexity in interactions between input modality and feedback of performing a task, in the field of classical solid mechanics. Having these results, a set of hypotheses is provided to test if some common satisfaction criteria can be predicted from their correlations with the components of performance, complexity, and overall acceptability. In the context of this research, three multimodal applications are implemented and experimentally tested to study the quality of interactions through the proposed hypotheses: a) full-body gestures vs. mouse/keyboard, in a Box game; b) arm/hand gestures vs. three-dimensional haptic controller, in a Slingshot game; and c) hand/finger gestures vs. mouse/keyboard, in a Race game. Their graphical user interfaces are designed to cover some extents of static/dynamic gestures, pulse/continuous touch-based controls, and discrete/analog tasks measured. They are quantified based on a new definition termed index of complexity which represents a concept of effort in the domain of locomotion interaction. Single/compound devices are also defined and studied to evaluate the effect of user’s attention in multi-tasking interactions. The proposed method of investigation for usability is meant to assist human-computer interface developers to reach a proper overall acceptability, performance, and effort-based analyses prior to their final user interface design.
