Welcome to Project Spatial Velocity!
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.
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
Initially, we would only invite up to two partners. If you are interested,
please contact Richard So for further
Thank you for your interest and we appreciate your help.
