for virtual reality along with the user’s degrees of ap-
preciation and control are open questions which will
guide the engine evolution. The significant engine
prototype response delay is not suited for a full au-
tomatic mode yet, but rather for punctual helps. This
drawback will be lessen but is an inherent part of our
approach. Ultimately the engine core will be tested
on more complex scenario. However, the next major
step is to obtain enhanced user’s intention hints.
