Centrale Nantes and AAU-CRENAU Laboratory will participate to the IEEE VR 2019. The 26th IEEE Conference on Virtual Reality and 3D User Interfaces will be held from March 23rd through March 27th, 2019 at the Osaka. Etienne Peillard (AAU-CRENAU) and the researchers from Université de Rennes 1, INRIA, INSA Rennes, CNRS, IRISA, IRT b<>com, Centrale Nantes will present the design of ten different 3D user interactions using passive haptics and embedded in an escape game scenario in which users have to escape from a pyramid in a limited time. Their solution is innovative by its modularity, allowing interactions with virtual objects using tangible props manipulated either directly using the hands and feet or indirectly through a single prop held in the hand, in order to perform several interactions with the virtual environment (VE). They also propose a navigation technique based on the “impossible spaces” design, allowing users to naturally walk through several overlapping rooms of the VE. All together, their different interaction techniques allow the users to solve several enigmas built into a challenging scenario inside a pyramid. See the video which describes this innovative solution.
