Co-location and tactile feedback for 2D widget manipulation

This study investigated the effect of co-location and tactile feedback on 2D widget manipulation tasks in virtual environments. Task completion time and positioning accuracy during each task were measured for subjects under 4 situations (co-located vs no co-located and tactile feedback vs no tactile feedback). Performance results indicate that co-location and tactile feedback both significantly improve the performance of 2D widget manipulation in 3D virtual environments. Subjective results support these findings.
