UnverifiedOptical tactile sensors such as GelSight, which provide high-resolution information about the contact surface, are one research direction for flexible object manipulation.79% similarUnverifiedThe GelSight tactile sensor was developed by Edward Adelson's team at MIT, capturing images of elastomer deformation via an internal camera and reconstructing the three-dimensional geometry of the contact surface using photometric stereo.74% similarUnverifiedTactile sensors such as GelSight and DIGIT have made important advances in recent years.71% similarUnverifiedGesture recognition typically first acquires images through a camera, then uses skin-color segmentation, contour extraction, or deep learning models to locate hand keypoints, and finally maps the hand pose to specific commands.70% similarUnverifiedTactile observation usually refers to force, pressure distribution, or contact event information obtained through contact sensing, and is direct evidence for judging whether the hand has actually acted on an object; in datasets that rely only on vision, contact can often only be inferred indirectly from occlusion relationships, which easily fails during fast motions or when the hand is occluded by itself.68% similar
