In spite of the radical enhancement of web technologies, many users still continue to experience severe difficulties in navigating web systems. One way to reduce the navigation difficulties is to provide context information that explains the current situation of users in the web systems. In this study, we empirically examined the effects of two types of context information, namely, structural and temporal context. In the experiment, we evaluated the effectiveness of the contextual navigation aids in two different types of web systems: an electronic commerce system and a content dissemination system. In our experiment, subjects performed several browsing tasks and answered a set of post-questionnaires. The results of the experiment reveal that the two types of contextual navigation aids significantly improved the performance of browsing tasks regardless of different web systems. Moreover, context information changed the users' navigation patterns, and increased their subjective ease of navigation. This study concludes with implications for understanding the users' browsing patterns and for developing effective navigation systems. Copyright ACM 2000.

Retaining customer loyalty is crucial in electronic commerce because the value of an Internet store is largely determined by the number of its loyal customers. This paper proposes a multi-phased model of customer loyalty for Internet shopping, which fully takes the characteristics of the Internet and cyber shopping into consideration. In order to validate the model, we conducted a web-based survey of the customers of various Internet stores, and the data was processed using structural equation analysis. The results indicate that several factors can effectively increase customer loyalty towards an Internet store and that the relative importance of the identified factors varies according to the level of involvement with the product purchased through the store. We suggest several managerial implications in developing Internet stores for higher customer loyalty based on these results. Copyright ACM 2000.

We are developing a prototype storytelling robot for use with children in rehabilitation. Children can remotely control a large furry robot by using a variety of body sensors adapted to their disability or rehabilitation goal. In doing so, they can teach the robot to act out series of movements or "emotions" and then write stories - using a storytelling software - including those movements in the story. The story can then be "played" by the remote controlled robot, which acts out the story. We believe that this robot can motivate the children and help them reach their therapy goals through therapeutic play, either by exercising muscles or joints (e.g. for physically challenges children) or by reflecting on the stories (e.g. for children with developmental disabilities). We use an innovative design methodology involving children as design partners.

The development of navigational tools for a web site devoted to a catalog of musical compositions offers a variety of design challenges. A combination of techniques developed from information visualization research - including starfield displays, dynamic queries, and zoomable user interfaces (ZUIs) - was used to construct a prototype browser for possible use in a web site dedicated to the work of Philip Glass. After a discussion of the goals and potential users of the site, this paper describes several prototypes that were developed and how they informed the design of a zoomable starfield browser. Unresolved design challenges and possibilities for future work are also discussed.

Multiple coordinated visualizations enable users to rapidly explore complex information. However, users often need unforeseen combinations of coordinated visualizations that are appropriate for their data. Snap-Together Visualization enables data users to rapidly and dynamically mix and match visualizations and coordinations to construct custom exploration interfaces without programming. Snap's conceptual model is based on the relational database model. Users load relations into visualizations then coordinate them based on the relational joins between them. Users can create different types of coordinations such as: brushing, drill down, overview and detail view, and synchronized scrolling. Visualization developers can make their independent visualizations snap-able with a simple API. Evaluation of Snap revealed benefits, cognitive issues, and usability concerns. Data savvy users were very capable and thrilled to rapidly construct powerful coordinated visualizations. A snapped overview and detail-view coordination improved user performance by 30-80%, depending on task.

GOMS is many things to many people, It is the only validated analytic usability evaluation method (UEM) in the field of human-computerinteraction. It is being used by practitioners at some of the world's largest and some of the smallest software companies. It is a research agenda that is being pursued at umversities the world over. It is a task analysis technique with roots in both cogmtive psychology and artificial intelligence. It is a flexible tool that can be used with protocol analysis. It is a technique that makes detailed profiling possible. It is an important adjunct to usability testing. It is something that can be done at the early stages of the: design process. It is a way of intelligently playing what /f games with interface possibilities. It is all of these things and more.

Costly props, complicated authoring technologies, and limited access to space are among the many reasons why children can rarely enjoy the experience of authoring room-sized interactive stories. Typically in these kinds of environments, children are restricted to being story participants, rather than story authors. Therefore, we have begun the development of StoryRooms, room-sized immersive storytelling urrent technology implementation and example StoryRooms.
We have begun the development of a new robotic pet that can support children in the storytelling process. Children can build their own pet by snapping together the modular animal parts of the PETS robot. After their p...
