Problems solved by technology

[0005] The inventors found that the current sensory reconstruction system mainly focuses on establishing a suitable neural interface between the human-physical device, which can convert the signal of the physical device into an easy-to-use The sensory feedback pathway and motor control between the physical equipment and the human body can achieve the effect of closed-loop control, but there is still no vibration stimulator based on a multi-channel modulation system, which cannot realize the tactile perception of precise force enhance

Embodiment 1

[0045] Embodiment 1 of the present disclosure provides a wearable vibration and tactile somatosensory device. The entire vibration device includes a cuff made of 8cm*20cm high-elastic cloth. The elasticity of the cloth ensures that the vibration motor attached to it will not It drives the rest of the body to vibrate, making it difficult for the wearer to distinguish. The 4 vibration motors are pasted in the middle of the fabric, distributed in a circular shape, and the distance between them also ensures that they do not affect each other when vibrating. The motor uses a 5mm disc vibration motor, the minimum vibration voltage of the motor is 1.3V, and the maximum input voltage is 5V. There is a loophole in the middle right of the cuff, which can be put on the thumb or directly tied to the upper arm when using it with the hand. There are Velcro fasteners at both ends of the cuff for easy wearing and taking off.

[0046] The structure of the cuff is as figure 1 As shown in A, t...

Embodiment 2

[0049] Embodiment 2 of the present disclosure provides a control method of a wearable vibratory tactile somatosensory device, which is used to convert input stimuli into vibration stimuli. Since the effect of human body perception of vibration stimuli depends on the sensitivity of skin touch, it needs to be used according to The guidelines in Part IV test skin tactile sensitivity to determine the lower limit of the intensity of the vibration output.

[0050] Since the vibration amplitude and frequency of the vibration motor are in a linear relationship with the input DC voltage between 1.3V-5V, the working voltage of the motor is set in this linear working area. If the motor input voltage is set as a linear function of the input stimulus intensity, a linear mapping relationship is established between the input stimulus intensity and the output vibration intensity. In practical application, the pulse-width modulation (Pulse-width modulation, pwm) wave of the single-chip microco...

Abstract

The invention provides a wearable vibration tactile motion sensing device and a control method, the wearable vibration tactile motion sensing device comprises a wearable part made of an elastic material, wherein the wearable part is provided with a plurality of vibration motors circularly distributed along the center of the wearable part, and each vibration motor is in communication connection with an external control terminal; the control terminal sets the vibration amplitude of the vibration motor according to a preset mapping relation between the input stimulation intensity and the output vibration intensity. A vibration feedback mechanism is adopted, tactile stimulation and ontology sense stimulation are converted and coded into vibration stimulation which is easily perceived by a human body, the vibration stimulation is generated by the wearable vibration device, and a wearer can learn a mapping relation from tactile stimulation and ontology sense stimulation to vibration stimulation after short-time training. Then, the degree of related input stimulation can be efficiently obtained in real time through vibration stimulation, and the accuracy of vibration sensing is greatly improved.

Description

technical field [0001] The present disclosure relates to the technical field of wearable tactile somatosensory equipment, in particular to a wearable vibrotactile somatosensory device and a control method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Human limbs have a sophisticated tactile perception system, which is an important basis for dexterous and fine movements. When touching an object with the arm, the mechanoreceptors in the skin will convert the obtained vibration sensation into a tactile signal and transmit it to the central nervous system; Analysis, decision-making and planning, sending movement commands to peripheral nerves, mobilizing limb joints to complete corresponding movements. This fusion of perception and movement is at the heart of precise motor control in the human body. [0004] However, a variety of centra...
