VR Grabbers: Ungrounded Haptic Retargeting for Precision Grabbing Tools
summary
A passive system provides realistic feeling for tweezerlike tools by visually retargeting handle convergence while keeping only passive hardware, built as a chopsticklike controller with tracking and a potentiometer called VR Grabbers. The paper claims and measures that Ungrounded Haptic Retargeting yields an unnoticed control-display range of 0.71–1.77 control-display ratio and positional offsets around (-1.48, 1.95) cm, with a user study showing ~2s faster task times and higher realism for objects under 2.95 cm.
