Abstract

An information input device comprises five input units containing sensors. The number of input units corresponds to the number of digits on a hand. Each input unit for the index finger, middle finger, ring finger and little finger, respectively, contains four sensors mounted on the inside surface of the unit. In the input unit for the thumb, the sensors are arranged on two lateral inside surfaces and on the end, lower and upper inside surfaces of the unit. The information input device comprises a palm rest, the shape of the outer convex surface of which is approximate to the shape of the surface of a cast taken of the surface of the palm of a person's hand when the hand is in a relaxed state. The input units serve to accommodate the fingers in a relaxed, semi-flexed position.

Description

NAME OF UTILITY MODEL: DEVICE FOR INPUT OF INFORMATION

TECHNICAL FIELD

The utility model relates to input devices and is intended, inter alia, to input (input) data or signals into a computer or other electronic device, play computer games, control various mechanisms directly and at a distance, for example, construction, road, military equipment, unmanned aircraft (drones, quadrocopters).

PRIOR ART

A device for entering alphabetic and symbolic information is known from the prior art, comprising letters and symbols input nodes mounted in a housing, a spacebar, register switch keys, configured to change the set of letters and symbols corresponding to each mentioned input node. The number of input nodes mentioned corresponds to the number of fingers of the right and left hands, with the exception of the thumbs. Each finger is designed to service one input unit of letters and symbols. Each of the above input nodes is designed as a body of rotation and a displacement sensor designed to register the direction of movement of the body of rotation, with the specified input node serviced by the little finger of the left hand to enter the following letters: A / F, Q / D, / I ; The specified input unit, serviced by the left-hand ring finger, is designed to enter the following letters: S / Y, W / C, X / H; The specified input node, served by the middle finger of the left hand, is designed to enter the following letters: D / B, E U, C / C; The specified input unit, serviced by the index finger of the left hand, is intended to enter the following letters: F / A, R / K, V M, T / E, G Π, B / I; The specified input node served by the index finger of the right hand is designed to enter the following letters: J / O, U / Γ, M / L, Y / H, H / P, N / T; The specified input node, served by the middle finger of the right hand, is designed to enter the following letters and symbols: К / Л, Ι / Ш, </ Б; The specified input node, serviced by the ring finger of the right hand, is designed to enter the following letters and symbols: L / D, O / Sch,> / Yu; The specified input node, serviced by the little finger of the right hand, is intended to enter the following letters and symbols :: / Ж, Р / 3,? /, {/ X, E,} / b (RU 2182352, 05.05.2002, IPC G06F 3/02).

An ergometrically enhanced keyboard is also known, having keys arranged and labeled so that they operate using movements. fingers, which largely mimic those that are currently used by the driver using the standard QWERTY keyboard. The keyboard is divided into two separate sections, one of which is intended for use by the operator’s right hand, and the other one is intended for use by the left hand to ensure independent positioning of the two sections relative to each other. Each section of the keyboard includes a case that has a raised central part designed for ergometric support and keeping the operator's hands in a natural, relaxed position, from which all keys can operate without significant hand movement. The fingers and thumb are located in the respective cavities, each of which has a plurality of pushbutton switches located therein for engagement with the thumb and fingers, with minimal and unique finger movement needed to activate any key. Each key touches a separate part of each finger, providing differential tactile feedback. The fingers and thumbs should never move out of the cavities, while the hands are constantly kept in one comfortable position. There is a wide use of thumbs (US 4913573, 04/03/1990, IPC B41J 5/10; G06F 3/023; NOSH 13/807).

The disadvantage of these devices is the inconvenience of operation, due to the need to exercise the fingers of the index, middle, nameless and little finger movements to the right and left to enter alphabetic and symbolic information. It is easy to carry out these movements only to people with special skills, for example, musicians. For people who do not have special training, it is difficult to perform these movements, therefore, when moving the fingers to the right - to the left, tension arises in the hand, which leads to its fatigue.

A keypad for a push-button activated device is known, including a plurality of keys designed to be driven by moving the operator’s fingers down, forward, backward and upward relative to the keys contained in each finger position: (a) the first key placed between the keys has essentially horizontal contact surface and is located for downward actuation; (B) the second key is located near and at an angle relative to the first key, located for direct actuation; (c) the third key is placed side by side, at an angle and oppositely opposite to the second key, located for reverse actuation; and (d) the fourth key is located above the first key and is located for lifting upwards (US 4,265,557, 05/05/1981, IPC B41J 5/08; B41J 5/10). This device has the following disadvantages:

1. The thumbs of both hands only affect the space bar, so that the functionality of the specified device is limited.

2. When working, the operator must move the hands, since the eight fingers must serve eleven input nodes. Thumbs are in contact with the space bar and do not work in input nodes. Due to the movement of the hands, tension arises in them, which leads to fatigue.

3. All input nodes are made of the same size, and fingers of the hand differ from each other in size. Therefore, in the input nodes one or two fingers can work, and the other fingers will not fit ergonomically: the little finger will not reach the far key, and the middle finger will rest against the far key.

As a prototype, a control keyboard is selected, containing keys actuated by the operator’s fingers. The purpose of the invention is to allow the keys to be operated without any movement of the operator’s hand. For this purpose, means are provided for immobilizing the keyboard case against the palm and back of the hand, allowing the fingers to move freely. Each key is positioned so as to be actuated with one finger. According to one embodiment, the various keys are activated by the first, second and third phalanges of the same finger (WO 8201345, 04/29/1982, IPC B41J 3/26; B41J 5/10; B41J 7/00; G05G 1/01; G06F 3 / 02; G06F 3/023; NOSH 13/12; NOSH 13/14; NOSH 13/807).

The disadvantages of this device are:

1. Due to the fact that the hand is fixed in the keyboard, there is no possibility to quickly extract it from the keyboard to perform other actions other than data entry by the hand.

2. When the control keyboard case is immobilized on the hand, the hand is squeezed, which leads to poor circulation and fatigue.

3. The thumb interacts with a small number of keys, which reduces the functionality of the device.

4. Since the index fingers, middle finger, ring finger, and little finger are in a bent state, tension arises in the hand, which leads to fatigue and increases the likelihood of false positives when the fingers are relaxed. DISCLOSURE OF USEFUL MODEL

The task, which the proposed utility model is aimed at, is to create such a construction of a device for entering information that would eliminate the disadvantages indicated above.

The technical problem solved by the creation of the claimed utility model is to create a more ergonomic and more user-friendly device for entering information that allows you to quickly release the brush for performing actions that are not related to data entry, which has great functionality by placing in the node for thumb more sensors. Using the proposed device will reduce the likelihood of false positives, the voltage in the hand will decrease.

Adjusting the device to enter information depending on the size of the user's hand is as follows:

- each input unit 1-5 moves from the palm rest 7 and back and is fixed depending on the length of the finger;

- palm rest 7 also moves from input nodes 1-5 and back, as well as in height, depending on the size of the palm. To fine-tune and increase and decrease the amplitude of the fingers, it is possible to replace the keys on the sensors 6, namely, to replace the low keys with the high keys and vice versa, which will allow the device to be more precisely adjusted to the user's brush.

The described adjustment allows to adapt the device to enter information under the user's hand of any size.

INDUSTRIAL APPLICABILITY

The claimed device for entering information is more convenient for operation and ergonomic, due to the following factors. The functionality of the presented device is increased by placing in the input node for the thumb a larger number of sensors placed on five internal surfaces: end, two side, top and bottom. The thumb is intensively involved when working on the device for entering information, due to the fact that it has greater coordination, sensitivity and greater amplitude of movement compared to other fingers. When using the claimed device, the palm is stationary, only fingers move. The hand is in a relaxed state, there is no tension in it. The use of the presented device for entering information is the prevention of tunnel syndrome or carpal tunnel syndrome - a neuralgic disease that is manifested by prolonged pain and numbness of the fingers. The claimed device is not fixed to the user's hand, which allows you to quickly remove it from the device and perform other actions not related to data entry. When the hand is in a relaxed state, the probability of involuntary finger movements and random effects on the sensors (false sensor alarms) is reduced.
