Traveling on foot is the most intuitive way for locomotion. Infinite surface driven by actuators is an ideal device for creation of sense of walking. We selected a torus-shaped surface to realize the locomotion interface. The locomotion interface employs twelve sets of treadmills. These trendmills are connected side by side and driven to perpendicular direction. Infinite surface is generated by the motion of the treadmills. The walker can go to any direction while his/her position is fixed in the real world. Effectiveness of the device is tested by motion analysis and study on sense of distance.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

Comparatively very little effort has been expended on the user interaction components of VEs. As a result, VE user interfaces are often poorly designed and are rarely evaluated with users. Although usability engineering is a newly emerging facet of VE development, user-centered design and usability evaluation in VEs as a practice still lags far behind what is needed. This paper presents a structured, iterative approach for the user-centered design and evaluation of VE user interaction. This approach consists of the iterative use of expert heuristic evaluation, followed by formative usability evaluation, followed by summative evaluation. We describe our application of this approach to a real-world VE for battlefield visualization, describe the resulting series of design iterations, and present evidence that this approach provides a cost-effective strategy for assessing and iteratively improving user interaction design in VEs. This paper is among the first to report applying an iterative, structured, user-centered design and evaluation approach to VE user interaction design.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

We present a description of both the traditional data analysis tools and our virtual environment, and results of an experiment designed to determine if an immersive environment based on the XGobi desktop system provides advantages over XGobi for analysis of high-dimensional statistical data. The experiment included two aspects of each environment: three structure detection (visualization) tasks and one ease of interaction task. The subjects were given these tasks in both the C2 virtual environment and a workstation running XGobi. The experiment results showed an improvement in participants' ability to perform structure detection tasks in the C2 to their performance in the desktop environment. However, participants were more comfortable with the interaction tools in the desktop system.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

Our goal is to develop and/or adapt existing 3-dimensional technologies to provide training scenarios across the Internet in a form as close as possible to the appearance and interaction expected of live situations with human participants. We have produced a prototype system, JackMOO, which combines Jack, a virtual human system, and LambdaMOO, a multiuser; network-accessible, programmable, interactive server: Jack provides the visual realization of avatars and other objects. LambdaMOO provides the Web-accessible communication, programmability, and persistent object database. The combined JackMOO allows us to store the richer semantic information necessitated by the scope and range of human actions that an avatar must portray, and to express those actions in the form of imperative sentences. We describe JackMOO, its components, and a prototype application with five virtual human agents.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

The lack of the normal complement of cues may contribute to cybersickness and may affect operator performance. Previously (1998) we described the effect of adding vestibular cues during passive linear motion and showed an unexpected dominance of the vestibular cue in determining the magnitude of the perceived motion. Here we vary the relative magnitude of the visual and vestibular cues and describe a simple linear summation model that predicts the resulting perceived magnitude of motion. The model suggests that designers of virtual reality displays should add vestibular information in a ratio of one to four with the visual motion to obtain convincing and accurate performance.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.
