Problems solved by technology

Recently, a kind of VRgluv glove has been introduced abroad. This glove uses a force feedback device to generate the squeeze feeling of the object, and uses the brake device to hinder the finger movement to reproduce the softness and hardness of the object. However, the device is large in size and weight, difficult to operate and will impedes free finger movement
It is relatively late to enter the research field of force-tactile interaction for virtual reality systems in China. At present, this technical field is basically blank.
And most o

specific Embodiment 1

[0019] The glove hardware device includes a glove main body and a control box thereof. The arrangement of the motors on the tactile glove is as follows: figure 1 As shown, there are 10 linear vibration motors arranged on a single glove, arranged according to two motors for each finger, and the vibration motors are numbered, and the corresponding serial numbers are used to indicate and control the motors of each part. The linear motor of this glove It is a spring mass that moves in the form of linear motion. Its advantage is that it has a sense of direction during the motion and has a smaller area. When in use, the user wears a glove control box on his arm. The control box includes a central control module, a motor drive module, a wireless Bluetooth module, and a power supply component. The microprocessor of the central control module can perform high-speed processing of tactile-related information. According to the instructions of the microcontroller, a voltage signal of a sp...

[0021] figure 2 System block diagram showing the tactile reproduction method of gloves. After wearing gloves, the user places both hands within the detectable range of the gesture recognition device. The gesture recognition device spatially locates the hand through the infrared camera and detects the bending angle of the finger, and transmits this information to VR. host. The unity engine software of the VR host models the information transmitted by the gesture input device to generate a virtual hand model. The virtual hand moves with the user's hand. When the virtual hand collides with an object in the virtual environment, a collision detection is triggered to record the serial number of the colliding finger. and the surface texture roughness of the virtual object. The VR host wirelessly transmits the collision information to the microcontroller of the tactile glove through Bluetooth communication, and the microcontroller generates waveforms with specific voltage amplitudes...

specific Embodiment 3

[0024] In the "Fruit Ninja" somatosensory game, players need to use their arms to simulate katana in the current game. The gesture recognition device (Kinect) detects the player's hand movements and inputs them to the game console. Fly the fruits to get high score. But the player can't feel the real sense of touch and the shape of the fruit when touching the fruit, but with the present invention, after the user wears the tactile glove, when the virtual hand (samurai sword) in the game touches the virtual fruit, the game console sends micro-control to the glove. The controller sends the collision information, and the glove microcontroller maps the motor serial number according to the contact position between the virtual hand and the virtual fruit, calculates the amplitude and frequency of the mapped linear motor drive voltage based on the roughness of the fruit surface texture, and finally realizes the tactile sensation through motor vibration Real reproduction.

Abstract

The invention discloses a VR (Virtual Reality) system tactile glove device and an implementation method of the VR system tactile glove device. The device comprises a glove main body, a motor, a central control module, a motor driving module, a wireless communication module and a power supply component, wherein the motor is arranged in an interlayer, positioned in a finger movement joint part, of the glove main body, and is connected with the central control module through a conducting wire; the central control module is connected with the wireless communication module, the motor driving module and the power supply component through a connecting circuit; then the central control module is interconnected with a VR host through wireless communication. The method disclosed by the invention has the advantages that hand movement is detected through a gesture recognition device; detected information is input into the VR host, and a virtual hand is created by means of modeling through a game engine; a waveform signal with a certain frequency and amplitude is generated by means of performing virtual hand collision detection and object texture modeling, and a special motor on the glove is driven to vibrate by the waveform signal, therefore the shape and texture touch of a virtual object is represented; the tactile experience effect brought by VR equipment is greatly improved, and the effects of good maneuverability and high convenience degree are achieved.

Description

technical field [0001] The invention belongs to the field of force-tactile interaction, and in particular relates to a virtual reality system tactile glove device and an implementation method thereof. Background technique [0002] Virtual reality technology, also known as VR (Virtual Reality) technology, brings people a very real immersive experience in today's life and entertainment, but the existing VR system generally only has two aspects of visual and auditory reproduction. , Lack of reproduction ability in terms of force and touch, so the VR system has certain deficiencies and deficiencies in experience, such as insufficient human-computer interaction. In the existing foreign technologies, force-tactile interaction devices for virtual reality systems are mainly realized based on vibration motors, airbags, piezoelectric actuators, force feedback devices, and electrostatic forces. NeuroDigital Technologies of Spain has developed GloveOne, a tactile glove that uses DC vib...
