Abstract: Aiming at future haptic communication with low time delay, high reliability, and bi-directional interactions, the acquisition and representation methods of haptic signals are given based on touch sensation and characteristics. For the damage and loss of haptic signals in typical haptic and multi-modal scenarios such as remote industrial manipulation, telesurgery, immersive games, architectures of haptic signal recovery are proposed from perspectives of both the within-modal and cross-modal, respectively. Moreover, several haptic communication prototype systems are built, which can effectively realize remote haptic perception and feedback, promote the user’s immersive experience.
