Welcome to Project Spatial Velocity!

Introduction
Spatial Velocity (SV) is a newly developed measuring metric to quantify scene movements perceived by an operator exposed to a virtual environment. Details of this SV metric can be found in the following reference:

So, R.H.Y., Ho, A. and Lo, W.T. (2000) A metric to quantify virtual scene movement for the study of cybersickness: definition, implementation, and verification. PRESENCE, 10, pp.193-216.

Initial studies have shown that for an exposure of 30 minutes, the level of SSQ Total Score increases with increasing SV in both fore-and-aft and yaw axes. It is hypothesised that SV x duration of exposure will correlate with the average level of cybersickness.

Invitations
Currently, we are seek overseas partners so as to verify the relationships between SSQ scores and SVs in different virtual environments. Once joined as a partner, we will help our partners to work out the SVs for their VR simulations. In return, our partners will share the SSQ data collected during the simulations. These data will then be published as a join-authored paper.

Initially, we would only invite up to two partners. If you are interested, please contact Richard So for further details.

Thank you for your interest and we appreciate your help.
