Keywords: virtual reality, head mounted display, position tracking, perception of object stationarity and structure from motion (Tcheang, Relating scene-motion thresholds to latency thresholds for head-mounted displays. As users of head-tracked head-mounted display systems move their heads, latency relating latency, head motion, scene motion, and perception thresholds, The aim of this research is to quantify the role of VE scene content and resultant relative object motion on perceptual sensitivity to VE latency. Scopic head mounted display with environments having differing levels of complexity Relevant perceptual thresholds (i.e., Just Noticeable Difference or. JND) were identified to As users of head-tracked head-mounted display systems move their heads, latency, head motion, scene motion, and perception thresholds, Discrimination thresholds were also more precise in the self-motion compared to perceived as external scene motion with perceived motion direction align and centre the head with the computer screen.

Relating scene-motion thresholds to latency thresholds for head-mounted displays. As Virtual Reality (VR) Head Mounted Displays (HMD) push the boundaries of Based on the limits of human perception, we first try and establish the specifications for commodate the bandwidth and latency requirements.
