Abstract

The invention relates to the technical field of virtual reality, and discloses a virtual reality device and a posture perception and tactile reproduction control method. The virtual reality device comprises a glove which can be worn by a user, and the glove is internally provided with: a pressure sensor used for detecting the stress condition of each finger; a micro electronic gyroscope which is used for acquiring an acceleration signal and an angular velocity signal of the glove; a vibration type stimulation control and driving module which is used for generating vibration tactile sensation;and a single chip microcomputer which is used for calculating the position and the posture of the glove according to the acceleration signal and the angular velocity signal of the glove, and outputting an instruction to control the vibration type stimulation control and driving module. The position and the posture of the glove are obtained through calculation by detecting the acceleration signal and the angular velocity signal of the glove in real time, so that the hand action of a user is sensed, the spatial measurement precision is high, the real-time performance is good, the virtual realityequipment simulates touch sense through vibration, and touch sense feedback generated when the user experiences virtual reality is enhanced.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method for controlling haptic reproduction. Background technique [0002] With the continuous development of virtual reality technology (VR: Virtual Reality), people have higher and higher requirements for the dimension and level of VR product experience. A single 3D vision has been difficult to meet the needs of user experience. The requirements are getting higher and higher, and the requirements for real-time perception technology of space position and attitude are also getting higher and higher. [0003] In the invention patent of CN 107941208 A, a virtual reality spatial positioning method is mentioned. This method mainly uses 3D imaging glasses to realize spatial position measurement by using the principle of binocular distance measurement and positioning. The disadvantage is that the initial position of the target needs to be calibrated in advance. And must have ...
