This paper presents the designing process of Tourist Guiding app on iPhone. This app aims for assisting tourists to schedule their trip plan in detail. The designing process consisted of three phases: research, interface design, user evaluation. In order to focus on user-centered  research, two methods were carried out questionnaire survey, interview with participants. After the research was done, the results of research were analyzed and summarized so that the potential requirements were collected. Those requirements would decide the inclusive features of this app, such as navigation,plan a trip,search for transportation.  Meanwhile, the interfaces of this app were designed on the platform: Photoshop. Lastly, the paper prototype's evaluation was conducted with four participants. The valuable feedbacks was given and the improvements of the interfaces were done.

Electronic medical records (EMR) and computerized provider order entry (CPOE) are recognized as a means to improve quality of care and patient safety. This research examines factors that contribute to clinician acceptance of an EMR implemented in a pediatric hospital system and applies this knowledge to improve implementation methods to ensure they foster acceptance. A framework for User-Centered Implementation (UCI) was developed based on previous EMR and CPOE, technology acceptance, user-centered design, and change management research. The UCI framework identifies tools from change management and user-centered design and links them to the systems development lifecycle stage(s) at which they can be applied to achieve improved user acceptance. Next, a study examined clinician EMR acceptance in a pediatric hospital system at various points during their EMR implementation which employed a UCI-based methodology. Surveys before and after implementation of each phase examined physician, nurse, and other staff perceptions about the systems usefulness (performance expectancy (PE)) and ease of use (effort expectancy (EE)). Results indicate users had positive perceptions of system ease of use (EE) after implementation. Post-implementation PE ratings were neutral or positive for most users. Pre- and post-implementation regression models indicate the factors that influence PE change over time. Compatibility with clinician work practices was important both before and after implementation. Before implementation, users who perceived a greater need for the system and felt their needs were represented during design had higher expectations of system usefulness. After implementation, system characteristics including how well it supports clinical decision making and how easy it is to use influenced PE. Support provided by super users positively influenced both PE and EE after implementation. Based on these findings, guidelines for using UCI to improve clinician acceptance of EMR are presented. Designing EMR systems that are usable within the clinical work context enables clinicians to focus on the patient, rather than the system. Accomplishing this in practice is difficult given the complexity of EMRs and the dynamic clinical processes they support. This studys results indicate the UCI framework can be effectively applied to EMR implementations to improve the usability, utility, and, consequently, acceptance of these systems.

A great deal of effort has been put into developing Embodied Conversational Agent (ECA) systems that provide a human-like assistant in the user interface. However, little is known whether improvements to ECA interfaces made by such efforts can ever be significant from the users point of view. I studied user experiences with ECA interfaces and evaluated the ECA style of interaction with respect to user expectation, perception, behavior and performance. I introduce a conceptual framework that offers a holistic view of the design space of ECA systems. I also have created a middleware toolkit that facilitates rapid development of application content across different speech and animation platforms. A series of user studies has been carried out to investigate the similarities and differences between human-computer interaction and human-ECA interaction and between human-ECA interaction and human-human interaction. Results from these studies provide strong evidence that people are consciously aware of the capabilities and limitations of ECAs. Traditional GUI design heuristics should be carefully followed when designing ECA interfaces. Furthermore, the results soundly suggest that designers of ECA interfaces take extra care to accommodate individual differences and preferences. Social norms that guide human-human interaction greatly affect individuals expectation and perception of ECA characteristics. The findings support the argument that drawing from both human-computer interaction and human-human interaction can be significantly advantageous to the design of both effective and affective human-ECA interaction.

Public services have been provided in an electronic format to reduce time and cost and to improve service quality. In this context, significant investments have been made since 2003 in Turkey and many government agencies started to provide services via the Internet. Government agencies need to learn the effectiveness of the offered services and the benefits of these services to citizens. The purposes of this thesis are to evaluate e-government websites in a comprehensive manner and to identify website design related problems. Especially, the study focuses on user-centered design of the e-government application. For this purpose, 33 e-government websites are evaluated, and an interview was conducted with eight government agencies websites&rsquo / designers. As a result of these studies, the problems encountered while using government electronic services are identified. Also, causes of these problems are found out. The study aims to provide a guideline in order to design user-centered e-government applications.

Information access suffers tremendously in wireless networks because of the low correlation between content transferred across low-bandwidth wireless links and actual data used to serve user requests. As a result, conventional content access mechanisms face such problems as unnecessary bandwidth consumption and large response times, and users experience significant performance degradation. In this dissertation, we analyze the cause of those problems and find that the major reason for inefficient information access in wireless networks is the absence of any user-activity awareness in current mechanisms. To solve these problems, we propose three user-activity aware strategies for mobile information access. Through simulations and implementations, we show that our strategies can outperform conventional information access schemes in terms of bandwidth consumption and user-perceived response times.
