Lean and Elegant Motion Cueing in VR

Lean and Elegant Motion Cueing in VR

How do we best design locomotion interfaces for VR that provide "enough" physical motion cues (vestibular/proprioceptive) while still being effective, affordable, compact, and safe? Despite amazing progress in computer graphics and VR displays, most affordable and room-sized VR locomotion interfaces provide only little physical motion cues (e.g., vestibular & proprioceptive cues). To provide...

Transition into VR: TransLocation

Transition into VR: TransLocation

How can we ease users' transition from the real surroundings into the virtual world? Many of today’s virtual reality (VR) setups are very much focused on technical aspects rather then the benefits of a coherent user experience. This work explores the idea of enhancing the VR experience with a transition phase. On a physical level, this transition offers the user a meaningful metaphor for en...

iSpaceMecha

iSpaceMecha

Collaboration between the iSpace lab at SIAT and Mechatronics Undergraduate Interns to design and build a unique, virtual reality multi-modal motion simulator The iSpace program is centered on investigating what constitutes effective, robust, and intuitive human spatial orientation and behaviour. This fundamental knowledge will be applied to design novel, more effective human-computer interfaces ...
