Large screen projection-based display systems are very often not used by a single user alone, but shared by a small group of people. We have developed an interaction paradigm allowing multiple users to share a virtual environment in a conventional single-view stereoscopic projection-based display system, with each of the users handling the same interface and having a full first-person experience of the environment.Multi-viewpoint images allow the use of spatial interaction techniques for multiple users in a conventional projection-based display. We evaluate the effectiveness of multi-viewpoint images for ray selection and direct object manipulation in a qualitative usability study and show that interaction with multi-viewpoint images is comparable to fully head-tracked (single-user) interaction. Based on ray casting and direct object manipulation, using tracked PDA's as common interaction device, we develop a technique for co-located multi-user interaction in conventional projection-based virtual environments. Evaluation of the VRGEO Demonstrator, an application for the review of complex 3D geoseismic data sets in the oil-and-gas industry, shows that this paradigm allows multiple users to each have a full first-person experience of a complex, interactive virtual environment.

“…When these individuals gather in a meeting, they can selectively publicize these notes by transferring them to the shared display. Rekimoto has developed a similar system involving a shared display and private mobile devices [18]. Rekimoto introduces mobile computers and PDAs as common, spatially tracked interaction devices into his shared environment.…”

“…Wide-screen stereoscopic walls, CAVEs or even bigger theatre-like installations like the i-Cone [18] are an established part of the infrastructure for 3D graphics visualization, not only at research labs and universities, but also in large corporations, in particular in the automotive and in the oil-and-gas industry. Although these systems are large, expensive and difficult to maintain, they have eclipsed the use of small, inexpensive, personal head mounted displays (HMDs) in all but a few application areas.…”

Abstract.Conventional interaction in large screen projection-based display systems only allows a "master user" to have full control over the application. We have developed the VRGEO Demonstrator application based on an interaction paradigm that allows multiple users to share large projection-based environment displays for co-located collaboration. Following SDG systems we introduce a collaborative interface based on tracked PDAs and integrate common device metaphors into the interface to improve user's learning experience of the virtual environment system. The introduction of multiple workspaces in a virtual environment allows users to spread out data for analysis making use of the large screen space more effectively. Two extended informal evaluation sessions with application domain experts and demonstrations of the system show that our collaborative interaction paradigm improves the learning experience and interactivity of the virtual environment.

It is an interesting challenge to design input devices that are easy to learn and use and that allow a wide range of differentiated input. We have developed a novel joystick-like handheld input device as a 6DOF elastic rate controller for travel and ratecontrolled object manipulation in virtual environments. The NOYO combines a 6DOF elastic force sensor with a 3DOF source-less isotonic orientation tracker. This combination allows consistent mapping of input forces from local device coordinates to absolute world coordinates, effectively making the NOYO a "SpaceMouse to go". The device is designed to allow one-handed as well as two-handed operation, depending on the task and the skill level of the user. A quantitative usability study shows the handheld NOYO to be up to 21% faster, easier to learn, and significantly more efficient than the SpaceMouse desktop device.
