Human reaching movement is accomplished even when environmental conditions unexpectedly change in the real world. Since human arm is a redundant system, constraints must be introduced to determine a unique motor command, and simultaneously those should be changed flexibly to adapt to unpredictably changing environment. In this paper, we have implemented(More)
Head mounted displays (HMD) are widely used for visual immersion in virtual reality (VR) systems. It is acknowledged that the narrow field of view (FOV) for most HMD models is the leading cause of insufficient quality of immersion, resulting in suboptimal user performance in various tasks in VR and early fatigue, too. Proposed solutions to this problem(More)
Terrain elevation maps can be efficiently used for real-time collision processing for ground-bound travelers Maps. We extend this approach to handle objects that may fly freely in 3D space. The new algorithm makes effective use of allocated terrain image memory and does not require extra storage. It is easy to implement into any travel processing system.
