Effects of Hand Feedback Fidelity on Near Space Pointing Performance and User Acceptance

Participants : Sabine Coquillart, Olivier Martin, Andreas Pusch.

We conducted an experiment to test the effects of different hand representations on near space pointing performance and user preference. Subjects were presented with varying levels of hand realism, including real hand video, a high and a low level 3D hand model and an ordinary 3D pointer arrow. Behavioural data revealed that an abstract hand substitute like a 3D pointer arrow leads to significantly larger position estimation errors in terms of lateral target overshooting when touching virtual surfaces with only visual hand movement constraints. Further, questionnaire results show that a higher fidelity hand is preferred over lower fidelity representations for different aspects of the task [18] .
