The sensitivity of presence to collision response

The paper describes an approach to collision detection and response, and an experiment to examine the sensitivity of subjective presence to varying collision response parameters. In particular, a bowling game scenario was used with 18 subjects, and parameters representing elasticity, friction and accuracy of collision detection were varied. Presence was assessed through a questionnaire following the experiment. The results suggested that presence was sensitive to variation in these parameters, and in particular to the value of the parameter representing friction
