A device for tactile sensing of information is known, which contains a block of Sensors of tactile sensitivity with the excitation windings of electromagnetic vibrators, which is connected via a block of information to a preparation unit for the presented information including a pulse distribution unit 1.

A disadvantage of the known device is the low perception efficiency of tactile impacts.

The aim of the invention is to increase the perception of tactile influences.

The goal is achieved by the fact that a device for tactile information transmission, containing a sensor unit of tactile sensitivity with excitation windings of electromagnetic vibrators, connected through an information interface unit with a training unit for presented information, having a pulse distribution unit, has a display unit for tactile symbols, the terminals of which are connected to the first terminals of the respective excitation windings of electromagnetic vibrators and information outputs of the impulse distribution unit c, the second terminals of the excitation windings of the electromagnetic vibrators are connected to the other terminals of the tactile symbol indication unit.

FIG. 1 is a circuit diagram of the device of FIG. 2 - sensors on the left hand, a general view.

 A device for tactile perception of information contains (Fig. IJ node 1 for preparing the presented information, which consists of a block 2 controlling the duration of stimuli by inputs connected to a source of information in a binary code (not shown), exits to inputs of a block 3 generating signals, second and the third inputs of the clock frequency and the signal connected to the buses; Triggering the inputs of the 4 interval unit and the sequential update block 5 connected to it, the outputs of which are connected to the additional inputs of the control unit 2, and t Also from the pulse distribution unit 6, the inputs of which are connected to the address outputs of the control unit 2, the outputs of the signal generating unit 3 and the power bus.

The outputs of the pulse distribution unit 6 are connected to the windings 7 for exciting the first 8 and second 9 groups of 10 tactile sensitivity sensors, respectively, for the left and

right hand. The node 1 is partially placed in the housing 11 (Fig. 2), connected to the bracelet 12 worn directly above the wrist 13 of the arm.

The device (Fig. 1) additionally includes a block 14 of indication of tactile symbols, made mainly on LEDs 15, one contacts of which are connected in parallel to the windings 7 of the excitation and the others to the common power bus 16.

The masks 17 with the image of the letter - equivalent to the tactile hum with the corresponding address are grouped into cells 18 of the display unit 14 so that their position is in the mass of the tab (taking into account the angle of rotation 75-80 ° corresponds to the sensor coordinate 19-23 on the fingers.

Structurally, the cells 18 of the display unit 14 are fixed on the elastic base 24, which is located on the back of the hand along the line A-A, connecting the radiocarpal joint 13 to the proximal joint 25 of the finger.

The sensor unit of tactile sensitivity consists of the first 8 and second 9 groups of 10 sensors of tactile sensitivity, with one pins of the display unit 14 tactile symbols connected to the first output of the corresponding electromagnetic exciter windings 7 and the information output of the pulse distribution unit b, the second terminals of the excitation windings 7 Electromagnetic vibrators are connected to other terminals of the tactile symbol indication unit 14.

Consider the operation of the device in the learning mode.

In this mode, the output of textual information from the accumulator, in which it is stored in the binary standard code, is carried out according to the address part of the code as requested by the signal conditioning unit 3, after the Start signal.

Block 2 is designed to generate a code equivalent to the duration of tactile stimuli (TC). In this mode, the vehicle duration is pre-recorded by the operator from the console (not shown / as averaged values separately for vowels and consonants of the vehicle, equivalent to speech signals. In block 3, by the time duration code, a wad of pulses is generated from the clock frequency by simultaneously generating a period separating consecutive signals. The operation of the code exchange unit 5 is carried out: a readiness signal is issued to an external device (accumulator), a gate generation control for interrogating the memory cells unit 2, pulse shaping, forming interval duration corresponding guide separated from a subsequent vehicle.

Thus, the inputs of the pulse distribution unit 6 from the output of block 2 receive the channel address code, which must be open for the period of formation of the vehicle. The signal input of block 6 receives a burst of pulses with a following frequency of 200-210 Hz and a duration formed in block 3. In addition, a constant voltage is applied from the source for the operation of the elements of node 1 and block 6. Unit 6, in accordance with the address part of the TC code, ensures that a burst of pulses goes along one or another winding 7 of the first 8 or second 9 groups of the sensor block.

In accordance with the transfer text, the sensor unit provides not only the excitation of skin receptors

analyzer on the surface areas of the fingers adjacent to the corresponding sensor 19-23, but also highlights in the corresponding cell 18 (FIG. 2) this or that mask 17 with the letter symbol equivalent to the current vehicle, since parallel to the winding 7 the pulses of the packet follow through corresponding LED 15.

Completing the visual analyzer with supporting stimuli provides an accelerated fixation of the quasi-speech reflex and shortens the duration of training.

The invention allows to extend the functionality and provides operator training in parallel with the perception of the vehicle. In addition, it reduces costs and shortens the duration of training. The sensor unit is characterized by simplicity and reliability of the design, which allows the operator to master the professional skills.
