I posted a message last week sometime about a project that I am working on to try and isolate the flow of data in VR system - I just want to thank everyone who replied for their input. Another topic that I would like to hear peoples feelings on is what actions a user needs to perform in a virtual environment. Do you think that it is possible to isolate a small number of distinct actions which will satisfy all (or most) VR applications? If so, what are they? I currently have a list of 5 that I feel satisfy most applications. These deal only with interaction between the user and the environment: Grab - attatch to and manipulate an object Drop Point - select an object e.g. using ray-casting techniques UnPoint Press - currently used to activate virtual menus Any comments, suggestion, additions?
