RU2546441C2 - A. lavrovsky's validator for operation with keyboard and tablet - Google Patents

Abstract

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a training device. The technical result is achieved by designing a device which helps coordinate movement upon contact with a plane with physical data, provides comfortable contact with an object and reduces redundant body work. Essential features of the invention are that it consists of a closed tube bounded on two sides to form a container, the tube being partially filled with a liquid except the free space in the form of a bubble. The tube can have any diameter and the liquid can have any colour. The tube is made of flexible, transparent material and has six movable marks; five marks are located along the tube at a level corresponding to the proximal peak of metacarpal bones and are numbered according to the general numbering of fingers; the zero mark is placed between the marks of the first and second fingers. The marks can be made using any method, for example braces worn on top of the tube. The device is fastened in the distal part of the forearm near the protrusion above the wrist on the side of the first finger and at the head of the elbow bone on the side of the fifth finger using a strap and is placed on the back of the hand. Practice shows that the positioning of hands during manual contact with a working surface is made intuitively and, seemingly, convenient and comfortable arrangement of hands is often an illusion due to lack of skills for harmonic contact with the object. This further leads to motive problems, fast fatigue and in professional occupation, internal crisis and deep depression, which slows down professional growth and operation of the structure as a whole.

EFFECT: acquiring skills for correct positioning of hands during manual contact with a working surface - an external keyboard, active monitor display, tablet computer, control panel etc.

Description

Validator for working with the keyboard and tablet of A. Lavrovsky.

The invention relates to a training device, and, in particular, to the acquisition of skills in the correct position of the hands with manual contact with the work surface - an external keyboard, active monitor display, tablet computer, control panel, etc.

A utility model is known from the prior art [Russian Patent No. 66028, IPC G01C 9/34, Level / V.V. Klochikhin (Russia) - 2007110196/2; Announced March 20, 2007; Publ. 08/27/2007].

The disadvantage of the device is that the marks are applied to the viewing windows, they are not movable, another disadvantage is the inability to fix the device in the arm area - these facts do not allow the device to be used to train the correct position of the hands.

The invention is known from the prior art [Patent SU No. 1219047, IPC АВВ 5/02, Pulse Sensor / Sverdlovsk Research Institute of Occupational Health and Occupational Diseases (Russia); Stated April 18, 1984; Publ. 03/23/1986].

The disadvantage of the invention is that the sensor is only for measuring pulse and pressure.

The objective of the invention is to provide a device that will track the correct positioning of the fingers when in contact with horizontal, sogital and frontal planes, for example with an external keyboard, an active display monitor, tablet computer, etc.),

The technical result is achieved by creating a device that will help coordinate the movement in contact with the plane with our physical data, provide comfort of contact with the object, and reduce unnecessary body work.

The essential features of the invention is that it consists of a closed tube, bounded on both sides to form a container, inside the tube is partially filled with liquid except for the free space in the form of a bubble. The tube can have any diameter, and the liquid can have any color. The tube is made of flexible, transparent material, six movable marks are located on the tube, five marks are located along the tube at the level corresponding to the proximal crest of the metacarpal bones, and are numbered in accordance with the generally accepted numbering of the fingers, the zero mark is located between the marks of the first and second fingers. Labels can be made in any way, for example, it can be brackets that are worn on top of the tube. The device is mounted in the distal part of the forearm near the protrusion above the wrist from the side of the first finger and at the head of the ulnar bone from the side of the fifth, using a strap and is located on the back of the hand.

The work of the proposed device is as follows.

The device works when the angle between the hand and the horizontal plane does not exceed 50 degrees. The device is mounted in the distal part of the forearm near the protrusion above the wrist from the side of the first finger and at the head of the ulnar bone from the side of the fifth, using a strap and is located on the back of the hand. The device is being configured. To do this, it is necessary to lean on the table with the wrist area, put the nail phalanx of the fifth finger vertically on the table, without lifting the wrist from the table. The bubble should be in the lateral part of the forearm at the level of the proximal crest of the metacarpal bone of the fifth finger. At the bubble level, a fifth movable mark is set. The same actions are carried out with the fourth, third and second fingers, also exposing three more movable marks corresponding to the numbering of the fingers. To set a movable mark for the first finger, it is necessary to put on the table the medial part of the tubercle of the nail phalanx of the first finger and set the first movable mark at the level of the bubble. A zero movable mark is set at the level of the bubble when the wrist rests on a horizontal surface. With proper operation of the hand, the bubble should be at the level of the set mark of the contact finger with the working plane.

Figure 1 shows a General view of the device, figure 2 shows a General view of the prepared for operation of the device.

A closed tube - 1, partially filled with liquid, has a free space in the form of a bubble - 2, there are six movable marks on the tube - 3, 4, 5, 6, 7, 8. The device is attached to the hand using a strap - 9.
