Haptic Augmentation by a Wrist Mounted Device with Laser Speckle Vibration Sensing and Hand Projection

Le résumé fourni par la source

We propose the wrist-mounted human augmentation device with laser speckle vibration sensing and hand projection that intuitively presents the vibration characteristics of distant objects to the user. By improving the portability limitations of conventional stationary systems, our wearable device can be used while moving or performing tasks. The system consists of a laser speckle vibration sensing unit using a high-speed event camera and a projection-based extended hand via a video projector. It suppresses body sway noise through threshold processing while providing tactile feedback to the user. Additionally, the visual representation of the extended hand allows users to recognize the source of the tactile stimuli intuitively. The proposed system holds potential for various applications, such as remote object inspection.
