The idea addresses the issue of tactile feedback when walking in Immersive Virtual Environments (IVE). The sense of presence sometimes falls flat when the texture of the physical floor does not match the perceived ground of the virtual environment. Experiments into improving the sense of self-motion are usually induced by stimulation of the haptic modality through use of vibrating actuators. While this is a sensible method, vibrating grounds is seldom a natural occurrence (especially at that frequency). Hence the illusion can be broken in situation when the participant e.g. stands still on a bumby surface in the virtual world with no haptic modality to support the sensation.
We propose a more static solution similar to tactile pavement but changeable:
3DUI Controller for VR-environment By: Kevin, Johan & Emil
The idea extends our own semester project that addresses ‘telekinesis’ as an extended sense, without being yet another IMU-based data-glove. In that sense the concept is closer to the MYO gesture-control armband. While the MYO relies on an IMU and muscle electrical impulses, we propose gesture controls via tracking of the flexor tendons in the wrist. We don’t know if this is feasible through optical tracking or of subcutis movement (or feasible at all).
As of now, we are merely working with a potential design, and have not yet been able to do observations. We are planning to observe how people (believe they) would utilize telekinesis as an extended sense. The observation needs to be semi-structured, possibly in the shape of a “wizard of Oz” experiment to determine the proposed interaction.
Besides being a completely new way to map gestures, we are proposing a relatively affordable 3DUI-controller, in our case with a VR-purpose in mind. The possibilities are broad, and such an artifact could inter alia be used for presentation, VR, game-controller and as an aid for people with e.g. muscular dystrophy. Most 3DUI controllers cost between 200-15’000$, and with an accelerometer/IMU and simple sensors the costs could be significantly reduced.
