Virtual reality displays introduce spatial distortions that are very hard to correct because of the difficulty of precisely modelling the camera from the nodal point of each eye. How significant are these distortions for spatial perception in virtual reality? In this study we used a helmet mounted display and a mechanical head tracker to investigate the(More)
When people move there are many visual and non-visual cues that can inform them about their movement. Simulating self-motion in a virtual reality environment thus needs to take these non-visual cues into account in addition to the normal high-quality visual display. Here we examine the contribution of visual and non-visual cues to our perception of(More)
When simulating self-motion, virtual reality designers ignore non-visual cues at their peril. But providing non-visual cues presents significant challenges. One approach is to accompany visual displays with corresponding real physical motion to stimulate the non-visual, motion-detecting sensory systems in a natural way. However, allowing real movement(More)
Serological surveys were made on individual sera of small animals trapped on Taiwan and offshore islands. The animals were shrews of the species Suncus murinus, and rats of the species Rattus rattus and R. norvegicus. The tests showed that on MaKung in the Peng-hu Islands (Pescadores), 66% of the shrews, 30% of the R. rattus and 15% of the R. norvegicus had(More)
