Abstract
In this paper we investigate how different conditions aiding perception in an online Virtual Reality application affect depth perception. The VR was developed for parents
experiencing feeding difficulties with their infants. The role of effective use of stereoscopic viewing, head tracking and animation is examined. In a complete block designed experiment subjects were asked to determine the positions of the spoon in the 3D environment. Task was done under different conditions: the animation of the baby model was either on or off and four different viewing modes were used: monoscopic or stereoscopic viewing with or without head
tracking. The use of head tracking improved the position perception when monoscopic vision without any animation applied. However, adding head tracking to stereo vision did not improve the position perception. The use of animation positively affected the judgment of depth perception under the monoscopic vision and makes it comparable with the performance under the head tracking mode. The outcome of this study provides insight into how to create more
interactive scene and enhance depth-related visual tasks by exploiting dynamic scene changes
