A fundamental problem is that tracking technologies which work well in a small enclosed environment do not function well over longer distances. In this paper, we describe Trike-a 'rideable' computer system which can be used to generate and explore large virtual spaces both visually and physically. This paper describes the hardware and software components of the system and a set of experiments which have been performed to investigate how the different perceptual cues that can be provided with Trike interact within an immersive environment.","PeriodicalId":375299,"journal":{"name":"Proceedings IEEE Virtual Reality 2000 (Cat.

Therefore, fish tank VR systems provide only a limited virtual workspace. As a result, such systems are less suited for displaying virtual worlds that extend beyond the available workspace and depth perception problems arise when displaying objects (virtually) located on the edge of the workspace in between the viewer and the display screen. In this paper we present two techniques to reduce this disadvantage: cadre viewing and amplified head rotations. The first aims to eliminate the problems in depth perception for objects with negative parallax touching the screen surround. Subjective observations from an informal user study indicate a reduction of confusion in depth perception. The second provides a transparent navigation technique to allow users to view larger portions of the virtual world without the need for an additional input device to navigate. A user study shows it performs equally well when compared to a technique based on the use of an additional spatial input device.","PeriodicalId":375299,"journal":{"name":"Proceedings IEEE Virtual Reality 2000 (Cat.

Subsequently, a derived application is described. For this, we use a hand-held planar mirror and address two fundamental problems of applying head tracking with rear-projection planes: the limited viewing volume of these environments and their incapability of simultaneously supporting multiple observers. Furthermore, we describe the possibility of combining a reflective pad with a transparent one, thus introducing a complementary tool for interaction and navigation.","PeriodicalId":375299,"journal":{"name":"Proceedings IEEE Virtual Reality 2000 (Cat.

The capacity of VE technology to create dynamic three-dimensional (3D) stimulus environments, within which all behavioral responding can be recorded, offers clinical assessment and rehabilitation options that are not available using traditional neuropsychological methods. This work has the potential to advance the scientific study of normal cognitive and behavioral processes and to improve our capacity to understand, measure, and treat the impairments typically found in clinical populations with central nervous system (CNS) dysfunction. The paper provides a rationale for the application of VE technology in the areas of neuropsychological assessment and cognitive rehabilitation, presents a tabled summary of the VE literature targeting cognitive/functional processes in clinical CNS populations and briefly describes two of our VE applications targeting attention and visuospatial processing.","PeriodicalId":375299,"journal":{"name":"Proceedings IEEE Virtual Reality 2000 (Cat.

Concurrency control is required to avoid inconsistent views among replicas due to multiple concurrent updates. G. Lann has developed a prediction-based concurrency control scheme to allow real-time interactions for users and to eliminate the need for repairs. The existing scheme does not scale in terms of delivering ownership on time as the number of users increases. In this paper, we propose a scalable prediction-based concurrency control scheme with entity-centric multicasting: only the users surrounding a target entity multicast the ownership requests, by using the multicast address assigned to the entity. The experimental results and analysis reported in this paper show that the proposed scheme achieves the benefits of prediction-based concurrency control with efficiency and scalability for large distributed virtual environments.","PeriodicalId":375299,"journal":{"name":"Proceedings IEEE Virtual Reality 2000 (Cat.
