Description of the prior art.

The prior art device for inputting information and signals including five input nodes containing sensors. The number of input nodes corresponds to the number of fingers. Each input node for the fingers of the index, middle, nameless and little fingers contains four sensors mounted on its inner surface. The device for entering information includes a palm rest, in which the shape of the external convex surface is close to the shape of the surface of the impression made from the surface of the palm of a person’s hand in a relaxed state of the hand. Input nodes serve for placing fingers in a relaxed bent position. (RU178284U1, publ. 03/28/2018).

It is also known an information input device configured to be mounted on a user's hand, comprising a touch panel integrated in the body, characterized in that the device body is made in the form of a wave-like curved plate containing a concave part, with the possibility of its placement on the inner surface of the user's fingers , and an arcuate bend of one of the sides, with the possibility of covering it with part of the index and / or middle finger, the touch panel is placed on the concave part of the body and is made concave, pr and this on the surface of the housing, the opposite surface with the touch panel, made an attachment element provided with recesses for the fingers and equipped with a mechanism for moving it on the surface of the housing (RU157660U1, publ. 04/13/2015).

Patent RU179301U1 (published on 05/07/2018) describes a useful model of a device for working with interactive devices, which is a virtual reality glove containing sensors located on the fingers of a glove and characterized in that IMU sensors located inside the glove are used as sensors.

In the patent US 7205979 describes a device for generating control signals for manipulating virtual objects in a computer system in accordance with gestures of an operator or other parts of the body; the device includes a glove, which includes sensors for detecting hand gestures, as well as hand position sensors connected to the glove and connected to a computer system to determine the position of the hand in relation to the system.

The disadvantage of the above devices is the inconvenience of operation, due to the fact that the fingers and palm of the user are busy all the time and can not be used for domestic operations without removing the device.

Closest to the claimed technical solution is the human-computer interface (US20180307314A1, 10.25.2018), representing the cathedral a circular array of sensors that read electromyographic signals, and constructs a control signal based on these data. The disadvantage of this device is that the electromyogram does not carry complete information about the picture of muscle contraction, in particular, changes in the handicap of the muscle and movement under the skin and, as a result, does not allow tracking the user's movements with high accuracy and reliability. In particular, if the sensor is located above the muscle fiber, which in turn is located above the other muscle fiber, then the total electromyographic signal during their reduction will not allow to determine the degree of contraction of each muscle individually. This problem is solved by determining changes in muscle shape and their relative movement. Thus, to achieve high accuracy of tracking the movements of the operator, it is necessary to obtain complete information about muscle contractions, which is achieved by using sensors of electric potential.

The problem to which the claimed technical solution is directed is to expand the arsenal of technical means in the field of human-computer interfaces, as well as to increase the convenience of entering information and signals.

The technical result achieved by the implementation of the presented utility model is to expand the capabilities for recording the movements of the human body, as well as expand the capabilities for controlling technical devices by recording the movements of the human body, which is achieved by:

application of electric potential sensors;

the possibility of integrating sensors in clothes or on the surface of clothes;

portability and compactness of the device during operation;

no need to remove the device when performing various household operations;

increase the accuracy of motion detection;

wireless data transfer to an external device.

The essence of the utility model is explained by the drawings, where in FIG. 1 shows one embodiment of a device for inputting information, a general view from two angles; in FIG. 2 shows one of the possible applications of the device - the input of control signals and / or information into a computer, formed by analyzing hand gestures using a circular array of electric potential sensors located on the forearm.

The device is an array of electric potential sensors installed in the immediate vicinity of the skin surface. The sensors are interconnected wirelessly and equipped with fasteners. The information received from the sensor array is fed to the built-in microcontroller, which processes and analyzes data, as well as transfers data to an external device wirelessly. Power is supplied by a built-in rechargeable battery or batteries. The device is equipped with on and off elements.

The following device versions are possible:

Option 1.

A wireless module consisting of a housing in which are mounted: one electric potential sensor, IMU sensor, a wireless module for collecting, processing and transmitting data to an external device (for example, such as Bluetooth), a button for turning on / off, a battery, a body mount element with adhesive surface, light indication in the form of one RGB diode. The device is installed in an arbitrary part of the body by gluing. The adhesive surface is made in the form of a strip around the electric potential sensor.

The operation of the device is organized as follows: with muscle contractions, the device captures an electromyogram, a change in the cross section of the muscle, as well as its movement during the contraction. When the device moves in space with the user's body, by applying IMU sensors, the device determines changes in angles relative to the initial position of the device. This information, in particular, can be used to move the cursor on the computer. Information on muscle contractions, in particular, can be used to emulate computer mouse clicks. For example, one short contraction of a muscle is a left click, and a long contraction is a right click.

Option 2

The device consists of an array of devices similar to option 1. Using the array can improve the accuracy of determining the movements of the user.

Option 3

The device is implemented as a circular array of electric potential sensors (Fig. 1-2) located in the forearm area, which includes 1 or more electric potential sensors, 1 or more IMU sensors, a microcontroller, means for wireless transmission of information to an external device, and a battery. The sensors are placed in separate housings, while protruding beyond the edge of the housing, which is oriented inward to the circular array. As an element of attachment to the body, there are two closed elastic bands encircling the arm. The sensors are connected to the battery and the microcontroller in a wired way, by soldering or connectors. The device collects information about muscle contractions in order to determine the movements of the hand, hand and fingers. To interact with the user, the device is equipped with a light indication on each module. The device has an on / off button. A USBMicro connector is used to charge the device.

The device works as follows: put on in the area of the forearm of the right or left hand, the modules are randomly oriented. At the moment of switching on, the device remembers the initial position of the hand. When making hand movements, the device determines the current angle of the hand relative to the initial position. When making movements with a brush and fingers, there is a contraction of the muscles of the forearm located under the array of sensors. The device reads the data of the contraction (electromyograms, shape changes and muscle movements) and, through subsequent data processing, determines the current position of the hand of the hand and fingers, and also understands what gesture is being performed at the moment. The received information is transmitted to an external device, where it is used to enter information and / or control.
