Embodiment 1

[0038] like figure 1 As shown, the virtual scene experience system with tactile simulation and emotional perception includes a scene computer 1 and a display terminal 3 respectively connected to it in communication, a tactile simulation and feedback device 2, and the tactile simulation and feedback device 2 is worn on the user's hand, which includes The microprocessor 201 and the second communication module 202, the positioning module 205, the skin touch simulation module 203, the memory 206 and the gyroscope sensor 207 respectively connected thereto; the physiological signal module 208 includes a blood pressure sensor, a muscle Electrical sensors and EEG sensors. The second communication module 202 communicates with the communication module of the scene computer 1 via the wireless network. The scene calculation 1 utilizes the positioning module 205 and the gyroscope sensor 207 of the tactile simulation and feedback device 2 to accurately track the trajectory and posture of t...

Embodiment 2

[0051] The skin tactile simulation device includes a fiber cloth 2031 worn on the user's limb and a tactile sheet 2036 arranged in the hole of the fiber cloth. A limit ring 2032 fixedly connected to the fiber cloth is provided outside the tactile sheet 2036. Multiple connections are made around the tactile sheet 2036. The point is connected with the end of the fiber rope 2033 evenly distributed along the limit ring 2032, the fiber rope 2033 is fixedly connected with the micro-piston 2034 in the thin tube away from the end of the tactile piece, the thin tube 2035 is connected with the hydraulic mechanism, and the thin tube 2035 is filled with hydraulic fluid. Driven by the hydraulic mechanism, the hydraulic fluid in the narrow tubes in different directions around the tactile sheet 2036 has different pressures, so that the fiber ropes connected to the piston in the thin tubes in different directions produce different pulling forces, and the tactile piece 2036 moves in different di...

Abstract

The invention relates to a virtual scene experience system with tactile simulation and emotion perception. The virtual scene experience system comprises a scene computer, and a display terminal and a touch simulation and feedback device which are respectively in communication connection with the scene computer; wherein the touch simulation and feedback device is worn on a limb of a user and comprises a microprocessor, and a second communication module, a positioning module, a skin tactile simulation module and a physiological signal module which are respectively connected with the microprocessor; the skin touch simulation module generates different pressures and shearing forces on the skin contacted with the skin touch simulation module according to the scene displayed by the display terminal and the limb position of the user, and simulates the touch of the user touching an object in the scene. The system provided by the invention provides a virtual scene for a user, accurately tracks the motion trail and posture of the hand of the user, simulates more vivid touch experience, can be widely applied to virtual simulation of various scenes, and greatly improves the user experience.

Description

technical field [0001] The invention belongs to the field of smart wearable devices, and in particular relates to a virtual scene experience system with tactile simulation and emotion perception. Background technique [0002] At present, virtual reality technology has been widely used in the product experience industry. A typical application scenario is the car driving experience under virtual reality: the user wears a VR headset and cooperates with force feedback gloves, car seats and other external In the real scene, you can feel the driving experience close to the real one. However, the senses provided by the aforementioned external devices have certain limitations. For example, the tactile sensation felt by the user is generated by directly touching the above-mentioned steering wheel and seat, but when the user touches other surfaces with the hand in the virtual reality scene, the tactile sensation cannot be generated, which reduces the user experience to a certain exte...
