Description

The invention relates to electronic engineering, and in particular to devices for entering alphanumeric information in computer systems, universal, portable and handheld personal computers, smartphones and other devices requiring operator input, in alphanumeric form.

Keyboards are known and widely used for entering alphanumeric information in computer systems, universal, portable and pocket personal computers [1]. Keyboards, which are used as a separate unit and laptops, require a workstation for the operator. In handheld personal computers, the keyboard is mounted in the case and occupies a significant place, reducing the screen area and reducing usability.

Known devices that facilitate the operation and input of alphanumeric information in computer systems, universal and portable personal computers, which programmers and users of personal computers call the "mouse." Portable personal computers use the “touch panel” device, a more compact version of the “mouse,” and which performs the bulk of its functions [2].

The closest in technical essence to the proposed device is a device for entering alphanumeric information [3].

The prototype, an alphanumeric information input device, is made in the form of two supports spaced apart at some distance on the plane of the operator’s table, the outer surface of which is made orthopedic, under the corresponding palms of the operator, when the hands are horizontally placed in a naturally relaxed position, and the electrical contact sensors of the input signals characters are installed under the fingertips and the supporting surface of the brush and have the ability to change the distance and angles between the longitudinal and transverse axes n and the plane of the operator’s table.

The prototype combines the keyboard and the mouse, but at the same time the visibility of the keyboard is lost, the knowledge of the key encodings and their combinations is required for work, a working skill and a strictly defined workplace are required. The proposed device combines a keyboard and a "touch panel", but at the same time the clarity of a conventional keyboard is preserved. The number of options for encoding keys and their combinations is slightly larger than the usual keyboard, but an order of magnitude smaller and simpler than that of the prototype. The proposed device allows you to comfortably enter information while standing, sitting, lying down and even while riding, as a passenger.

A distinctive feature of the proposed keyboard, a device for entering alphanumeric information, is the placement of all electrical contact sensors of characters in elastic films made in the form of the operator’s right and left palms, “gloves” worn on the operator’s hands, which are equipped with processing and transmission devices entered alphabetically -digital information on the computer, as well as power sources, with two linear electrical contact sensors in the form of strips mounted on a large and index p Altsakh, act as the "touch panel" of the computer, and the electrical contact character sensors in the form of contact strips, mounted under the thumbs, are designed to enter 10 digits on the right glove and the functions of the F1-F10 traditional keyboard on the left glove.

The drawing shows the proposed keyboard for entering alphanumeric information in the form of right and left "gloves" of the operator with a view "in the palm".

Devices for processing entered alphanumeric information and transferring to a computer, as well as power sources are located on the back of the gloves and are not shown in the drawing.

(Hereinafter, the description of the keyboard - “gloves”, the terms of the arrangement of parts are similar to the terms of the arrangement of parts of fingers, brushes and palms of the operator)

In elastic "gloves" there are 3 types of electrical contact sensors of symbols, and visible, drawn, luminous or embossed symbols of symbols are applied to the surface of the sensors.

Electrical contact sensors of symbols of the 1st type are designed to enter letters, symbols and switch registers or modes and are placed on both “gloves” on the inner side of the surface of the phalanges of the fingers, the side surfaces of the phalanges of the fingers, as well as in place of each nail.

The electrical contact sensors of symbols of the 2nd type in the form of contact strips are designed to enter 10 digits on the right glove and 10 functions F1-F10 of the traditional keyboard on the left glove. Character sensors of the 2nd type are placed on the inner surface of the palms of the "gloves", under the thumb.

Sensors of the 3rd type are placed on the left glove, consist of 2 linear electric contact sensors in the form of strips and are intended for use as a “touch panel”. One of the linear electrical contact sensors in the form of a strip is placed on the inside of the thumb, and the other on the side surface of the index finger.

The assignment of certain symbols to the "contact gloves" electrical sensors depends on the language of the input information and the individual wishes of the operator, has the ability to reprogram and does not relate to the essence of the invention.

The keyboard is used as follows: the input of letters, symbols and the installation of the necessary modes or registers is carried out by electrical contact sensors of the first type, by contacting the surfaces of the sensors of the thumb with the sensors of other fingers on both hands. This creates many combinations. For example: the surface of the first or second phalanx of the thumb with the rest of the sensors, with sensors mounted on the interdigital spaces of the phalanges, as well as sensors on the nails of the remaining fingers.

Entering any of the 10 digits is done by electric contact sensors of the second type, by touching the 1st, 2nd, 3rd and 4th fingers of the contact strip on the right palm (10 options).

Entering any of the 10 functions of the F1-F10 traditional keyboard is made by electric contact sensors of the second type, by touching the 1st, 2nd, 3rd and 4th fingers of the contact strip on the left palm (10 options).

The cursor on the monitor screen is controlled by moving, at an angle close to perpendicular, two linear electric contact sensors of the third type in the form of strips that are mounted on the thumb and forefinger of the left palm.

The entered information is processed and transmitted to a computer using electronic devices mounted on the back of the gloves. The software of these electronic devices removes false signals that may occur when interdigital sensors interact.

The proposed keyboard allows you to work comfortably without support for the operator’s hands, standing, sitting, reclining and even lying in front of the monitor. Work is done with greater speed and with less operator fatigue. The proposed keyboard facilitates working with a computer for people with disorders of the musculoskeletal system and bedridden patients.
