Haptic Feedback of Trapping Force in Manipulating Optical Tweezers
An optical tweezer is a technology that can trap under submicron diameter small objects by the translation of momentum of the photon. Because no reaction force is provided, manipulating particles with keeping adequate force is difficult. This study aims to develop an advanced optical tweezer system that measures the trapping force and present it to the operator as perceptual haptic feedback. Some experiments confirmed the developed system interactively generates viscous drag force and supports user’s manipulation.
