Nomad devices for interactions in immersive virtual environments

Abstract

International audienceRenault is currently setting up a new CAVE™, a 5 rear-projected wall virtual reality room with a combined 3D resolution of 100 Mpixels, distributed over sixteen 4k projectors and two 2k projector as well as an additional 3D HD collaborative powerwall. Renault's CAVE™ aims at answering needs of the various vehicle conception steps [1]. Starting from vehicle Design, through the subsequent Engineering steps, Ergonomic evaluation and perceived quality control, Renault has built up a list of use-cases and carried out an early software evaluation in the four sided CAVE™ of Institute Image, called MOVE. One goal of the project is to study interactions in a CAVE™, especially with nomad devices such as IPhone or IPad to manipulate virtual objects and to develop visualization possibilities. Inspired by nomad devices current uses (multi-touch gestures, IPhone UI look'n'feel and AR applications), we have implemented an early feature set taking advantage of these popular input devices. In this paper, we present its performance through measurement data collected in our test platform, a 4-sided homemade low-cost virtual reality room, powered by ultra-short-range and standard HD home projectors

From driving simulation to virtual reality

“…Extended HUD and AR systems now can be experimented in driving simulator and CAVE experiments. Convergence between driving simulation and VR technologies can also be observed in the recent evolution of driving simulation software (SCANeR © Studio, OpenSD2S) which integrate now virtual cockpit and stereoscopic view [39] as well as of high end visualization software tools (DeltaGen from RTT Dassault Systems) which integrates a real driving module with IPG's Carmaker vehicle dynamics solution. Along with those applications high quality finger tracking technics shall also be integrated for complete virtual immersion both for driving simulation and virtual reality systems [40].…”

“…Today, the advents of high resolution 4K digital display technology allows near eye resolution stereoscopic 3D walls and integrate them in high performance CAVEs. High performance CAVEs now can be used for vehicle ergonomics, styling, interior lighting and perceived quality [36]. One of the new application domains for both driving simulators and CAVEs, including CAVE like display system equipped driving simulators (Renault has recently invested in the upgrade of its motion based CARDS driving simulator with CAVE like display system with approximately 2 arc min resolution) is Augmented Reality (AR) vehicle equipment.…”

Evaluation of smartphone-based interaction techniques in a CAVE in the context of immersive digital project review

“…According to future assessment, the first implementation of this new metaphor in current industrial software versions used at Renault will be carried for SCANeR © Studio [19] used with Catia from Dassault Systems, merging virtual mockup data with virtual environment thanks to Techviz Fusion. First use-cases will concern exterior vehicle design and lightning [20].…”
