Description

Technical field

The invention relates to the field of computer technology and can be used to enter data into a computer or other devices using keys.

State of the art

A device for inputting information is known that improves the usability and speed of inputting information by reducing the distance the finger moves (RU 2159462, G06F 3/023). For this, the input device contains a key located on the panel and four pairs of emitter - radiation receiver, forming four optical axes with the possibility of their interruption by the working body when the key is pressed. The disadvantage of this device is the limited number of input characters on a single key.

Closest to the proposed is a data entry device comprising a panel, first and second keys located on the device panel, fourteen emitters and fourteen radiation receivers that form fourteen optical axes and a plurality of working areas on the surface of the keys (RU 2246749, G06F 3/02, the implementation option in Fig. 2). The operator clicks on the necessary working areas on the key, as a result, the corresponding codes are generated at the device output.

The disadvantage of this device is the interdependence of the keys due to the common optical axes (you cannot press a key until the cycle of the other key is completed), which complicates the design (some of the optical axes pass through the holes in the keys) and reduces the speed of information input. It is inconvenient to enter information with two hands while holding the device due to the large surface area of the keys. It is difficult for the finger of the hand to navigate on the surface of the keys when entering information, incl. "Blind" method (without looking at the keys). There is no possibility of selection of one working area with simultaneous exposure of a working body to several working areas.

SUMMARY OF THE INVENTION

The technical result achieved in the proposed device is the ability to work while holding the device in hands at a higher speed, ease of use and the ability to enter information "blind" by reducing the distance by which you need to move your finger, highlighting the working areas in height and a given priority, as well as reducing the size and simplification of the device.

The technical result is achieved in that the information input device comprising a panel located on the device panel of the first and second keys, fourteen emitters and fourteen radiation receivers is additionally equipped with a controller, the first and second inputs of which are connected respectively to the outputs of the first and second keys, the group input is connected with the corresponding outputs of the radiation receivers, the group output is connected to the corresponding inputs of the emitters, and the output is the output of the device, and on the panel Each key has seven emitters and seven radiation receivers, which pairwise form three longitudinal optical axes and four transverse optical axes for each key, parallel to the plane of the surface of the keys at a given distance, with the corresponding upper longitudinal optical axis passing in front of each key and the corresponding nearest to the center of the device, the transverse optical axis passes in front of the corresponding side of each key, which ensures the formation of twenty working zones for each key Vichy, which can be influenced by the working body, both on the surface and outside the keys at a distance that allows the radiation to overlap with the working body when they are pressed, and the working areas can differ in a given height and have the corresponding marking, and with the above-mentioned action on the keys and / or on the optical axes, the controller program according to the state of the radiation receivers of all closed and open optical axes provides the ability to program the corresponding codes, and when exposed to a working body, several workspaces controller program allocates a work area, located near the center and top of the unit as of the respective detectors.

List of drawings

In FIG. 1 shows a functional diagram of a device;

In FIG. 2 shows a top view of the device and a section along AA.

An example embodiment of the invention

The information input device comprises a panel 1, on which the first 2 and second 3 keys are located, the first 4 and second 5 groups of three longitudinal radiators, the first 6 and second 7 groups of four transverse radiators, the first 8 and second 9 groups of three longitudinal receivers radiation, the first 10 and second 11 groups of four transverse radiation receivers, which form the corresponding longitudinal and transverse optical axes of each key, the controller 12, the output of which 13 is the output of the device.

The first group 4 of three longitudinal emitters and the first group 8 of three longitudinal emitters form three longitudinal optical axes above the first key 2 (left), and the first group 6 of four transverse emitters and the first group 10 of four transverse emitters form four transverse optical axes above the first key 2, which are perpendicular to the longitudinal optical axes, with the upper longitudinal axis passing in front of the key 2, and the transverse right axis passing on the right side of the key 2, and the remaining optical Its axes extend above the surface of the key 2 and provide the formation of twelve working areas on the surface of the keys, and the longitudinal optical axis in front of the key and the transverse optical axis on the right side of the key 2 (closer to the center of the device) provide the formation of eight more working areas.

Similarly, the working areas of the second key 3 (right) are formed from the corresponding optical axes, only the leftmost transverse optical axis passes to the left of the second key 3 (closer to the center of the device).

Thus, the device has 40 working areas, when clicked, you can retrieve 40 codes (without switching registers).

One embodiment of the device with the corresponding marking of the working areas is shown in FIG. 2.

The optical axes of each key form twenty working zones in the form of five columns of four rows, with the marking of the top row and the column closest to the center of the device located on the device’s panel, and the remaining rows and columns are marked on the surface of the keys, respectively. Symbols that are removed with a finger extended beyond the key when it is pressed are marked on the surface of panel 1. In this case, when the key is pressed, the fingertip is above the corresponding marking.

With such an optimal number of working areas, it is most convenient to hold the device in your hands and simultaneously enter information with your thumbs from the corresponding keys.

After pressing the button, the controller of the device sequentially turns on the emitters and analyzes the state of their respective radiation receivers.

If the user presses, for example, with the right thumb on the “G” symbol on the second key 3 (right), then the second longitudinal (from the top) and second transverse (from the center) optical axes overlap. The controller program analyzes the state of radiation receivers of open and closed optical axes and generates the symbol code “G” at the output of the device, and the state of other closed optical axes is ignored. For example, if all the optical axes defining the symbols “D, W, U, Z, O, L, D, W, L, B, U” are blocked by the working body when the right button is pressed, the controller will set the symbol code at the output of the device "G" because radiation receivers that have identified the “G” symbol are closest to the center and top of the device, respectively.

To transfer, for example, the first key 2 to “Shift” mode, it is necessary to overlap the upper transverse optical axis at the second key 3 (in zone “S”). Similarly, you can put the second key 3 into this mode.

To switch the register in the controller 12, which would change the values of the codes of the working areas of the right (left) key (for example, numbers or other signs), it is necessary to block one of the optical axes of the left (right) key closest to the center of the device (in the zone “F ").

Switching the case allows you to enter an additional 40 codes. To increase the number of input codes, it is possible by analogy to overlap other optical axes.

Factors such as reducing the distance when moving the thumbs when entering information, the ability to maintain a fixed position of the hands while holding the device and simultaneously working on it with two hands, different height of the working areas, allowing the user's finger to navigate on the surface of the keys, ignoring side characters that fall under the finger in the process, allow you to enter information at a higher speed and greater convenience (including the "blind" method).

Industrial applicability

The proposed device has wide operational capabilities and provides convenient retention and simultaneous work with two hands, high speed data entry, as well as quick user training in the "blind" method. The device has a simple design with reduced dimensions, technologically advanced in production, which helps to reduce its cost.
