Background

The touch sense is taken as an important source for acquiring information by a human body, and has the characteristics of quick response, obvious perception and the like. For patients with visual impairment and other special populations, tactile sensation is one of the important ways to obtain information instead of vision. The tactile expression device converts the characteristic information of a specific environment target into a specific sequence, and can comprehensively, accurately and quickly transmit the target information to a user under the conditions that visual and auditory sense is obstructed or visual and auditory channels are occupied and other special confidentiality requirements exist. The touch expression technology research refers to the research of a vibration touch stimulation device, the design of an information coding scheme, and the transmission of certain specific information to a user by generating specific touch stimulation to act on the skin of a specific part of a human body.

The existing touch sensing device relates to vibration touch stimulation of tongue tip, waist, back, fingers and other parts, and rarely relates to neck. Meanwhile, in different vibration tactile stimulation paradigms, the interaction between the spatial and temporal characteristics of stimulation may cause the perception illusion to comprise the motion illusion, the positioning illusion and the like. In addition, the existing coding of vibration tactile information is generally based on Braille codes, and the learning of the coding symbols and the tactile perception need long-time repetition and extensive training, which becomes a barrier for the user to learn to use the tactile perception device to a great extent.

Wherein, the energy supply control module 3 controls the four vibration motors 3 to work according to the vibration stimulation instruction.

The working principle of the embodiment is as follows:

(1) Selecting external information to be transmitted, and transmitting the information to the vibrotactile stimulation device;

(2) Finding out a corresponding vibration stimulation instruction according to a pre-coded vibration tactile letter code table from the received information on the vibration tactile stimulation device;

(3) The control energy supply module 4 receives the vibration stimulation instruction and starts the corresponding vibration motor 3 according to the coding rule;
