Embodiment 1

[0038] as Figure 1As shown, a virtual scene experience system having haptic simulation and emotional perception, including a scene computer 1 and a display terminal 3 connected to its communication respectively, a haptic simulation and feedback device 2, a haptic simulation and feedback device 2 is worn in the hands of the user, which includes a microprocessor 201 and a second communication module 202, a positioning module 205, a skin haptic simulation module 203, a memory 206 and a gyroscope sensor 207 The physiological signal module 208 includes a blood pressure sensor, an electromyography sensor and an EEG sensor, respectively, connected to the microprocessor 201. The second communication module 202 is connected to the communication module of the scene computer 1 via the wireless network. Scene calculation 1 using a haptic simulation and feedback device 2 of the positioning module 205 and gyroscope sensor 207, accurately tracking the trajectory and attitude of the user's hand. ...

Embodiment 2

[0051] Skin haptic simulation apparatus, comprising a fiber cloth 2031 worn on the user limb and a haptic sheet 2036 arranged in the fiber cloth hole, the haptic sheet 2036 is provided with a limit ring 2032 fixedly connected to the fiber cloth, the haptic sheet 2036 is surrounded by a plurality of connection points and a fiber rope 2033 evenly distributed along the limit ring 2033 End connection, the fiber rope 2033 away from the haptic piece end and the micro piston in the thin tube 2034 fixed connection, the thin tube 2035 is connected to the hydraulic mechanism, The thin pipe 2035 is full of hydraulic fluid, driven by the hydraulic mechanism, the hydraulic fluid in the thin pipe in different directions around the haptic sheet 2036 has different pressures, so that the fiber rope connected with the piston in the thin pipe in different directions produces different tensile forces, and the haptic piece 2036 produces pressure and shear force on the skin of the user body in contact ...

Abstract

The present invention relates to a virtual scene experience system with tactile simulation and emotional perception, including a scene computer, a display terminal respectively connected to it in communication, a tactile simulation and feedback device, and the tactile simulation and feedback device is worn on a user's limb, and it includes a microprocessor device and the second communication module, positioning module, skin tactile simulation module, and physiological signal module respectively connected thereto; the skin tactile simulation module produces different effects on the skin contacted by the skin tactile simulation module according to the scene displayed by the display terminal and the position of the user's limbs. Pressure, shear force, simulate the tactile sensation of the user touching the objects in the scene. The system of the present invention provides users with virtual scenes, accurately tracks the motion trajectory and posture of the user's hands, simulates a more realistic tactile experience, and can be widely used in virtual simulation of various scenes, greatly improving the user's experience.

Description

Technical field [0001] The present invention belongs to the field of smart wearable devices, specifically relates to a virtual scene experience system having tactile simulation and emotional perception. Background [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, with force feedback gloves, car seats and other external equipment, you can feel the driving experience close to the real in the virtual reality scene. However, the perception provided by the above external devices has certain limitations. For example, the user's sense of touch is generated by directly touching the above-mentioned steering wheel and seat, and when the user touches other surfaces with his hand in the virtual reality scene, it cannot produce a sense of touch, which reduces the user experience to a certain extent. [0003] At present, most of...
