Description:

This paper examines the issue of spatial reality reproduction (SRR) caused by the natural difference between the human eye and the camera viewpoint in video see-through (VST) of the head-mounted display. We present a set of indicators and methods to objectively evaluate the performance of SRR, including scaling, positioning, distortion, motion distortion and stereo depth. Furthermore, we delineate the corresponding measurement equipment and measurement methods. A comprehensive evaluation of these indicators will allow us to establish a theoretical model. The model could, for instance, include the appropriate weighting of each indicator, which would then allow for the calculation of a final score after a weighted average. This would enable us to judge the strengths and weaknesses of the SRR performance of the headset.
