Abstract

The embodiment of the invention discloses a touch interaction method, a touch interaction device and a touch wearable device, which are suitable for a process of interaction between a hand of a user and a virtual reality (VR) or augmented reality (AR) scene. The method comprises the following steps of obtaining the gesture information of the hand of the user; obtaining a three-dimensional hand model corresponding to the gesture information of the hand of the user according to the gesture information of the hand of the user; detecting a collision model colliding with the three-dimensional handmodel through a collision detection algorithm; determining a stress model corresponding to the collision model, and determining the stress information of the three-dimensional hand model according tothe stress model; generating a collision touch instruction according to the stress information; and sending the collision touch instruction to the touch wearable device, wherein the collision touch instruction is used for enabling the touch wearable device to control a vibration motor in the device to vibrate. According to the embodiment of the invention, the vibration touch feedback which is based on the user gesture interaction and corresponds to the stress information is realized, and more real and richer touch experience is provided for the user.

Description

technical field [0001] The present invention relates to the technical field of tactile sensation, in particular to a tactile interaction method, device, and tactile wearable device. Background technique [0002] Haptic technology (Haptics) is an interactive technology that simulates the real sense of touch through electrical signal-driven tactile devices that are in direct or indirect contact with human skin. The sense of touch is an important channel for human beings to interact with the outside world besides vision and hearing. Human touch can be classified into: hardness, strength, vibration, friction, material, shape and temperature according to tactile clues; it can also be classified according to the technical means used: motor, vibration motor, air pressure, electrostatic force, air bag, temperature control , electromuscular stimulation, and tactile redirection. Due to the constraints of devices, research on the frontier of haptics is more focused on specific areas,...
