The utility model relates to devices for entering text into a computer.

State of the art

A known keyboard of a personal computer containing a panel of alphanumeric keys, a panel of command keys and a stencil superimposed on a panel of command keys. Moreover, the stencil having slots for the keys and on the surface of which the names and pictograms of the commands are applied can be turned over similarly to the sheets of the desk calendar. The stencil also contains a label made in the form of a bar code, the keyboard contains a device for reading code from stencil sheets, RU 2128361.

A more effective known keyboard of a personal computer, containing placed on the working panel of the case groups of main and auxiliary keys equipped with sign symbols and displacement or pressure sensors, the electrical outputs of which are connected through a signal conversion unit to one of the ports at the input of the computer; at least part of the keys of the main and / or auxiliary group are multi-positioned and are provided with several symbols of different signs, the corresponding number of independent sensors for their position or touch and a device to prevent the simultaneous operation of various signs and their sensors on each of the multi-position keys, at least one independent pair of main and / or auxiliary, including multi-position, keys made with the possibility of simultaneous operation for characters corresponding to this pair for generating additional signals at the outputs of their sensors through the matching circuit of the above-mentioned signs, the ergonomic size of the contact part of the multi-position keys remains the same, and the characteristic structural dimensions of the multi-position keys are smaller than the corresponding total dimensions of the single-position keys, RU 24006.

This technical solution was made as a prototype of this utility model.

The disadvantage of this technical solution is the need to move your fingers from key to key, which increases the time of entering information and complicates the operation of the device. Utility Model Disclosure

The objective of this utility model is to create a personal computer keyboard that reduces the time it takes to enter text (words) by eliminating the need to move fingers from key to key when typing one lexical unit (word) and thereby increase the usability of the device. According to a utility model, in the keyboard of a personal computer comprising a case with a working panel and multi-position keys located on the working panel provided with several symbols of different characters, programmable buttons T9 are used as keys provided with symbols of alphabetic characters.

The applicant did not find any known sources of information that contain information about using the T9 buttons as keys on the keyboard of a personal computer, which allows us to conclude that the utility model meets the “new” criterion (N).

The T9 button is a programmable button. The name T9 has been widely used for programmable buttons since 1996 and comes from the English phrase “Text on 9 keys”. The T9 button is used in cell phones, for example, SAGEM MC922 from SAGEM (France). Brief Description of the Drawings

In the future, the utility model is illustrated by a detailed description of examples of its implementation with reference to the drawings, in which: FIG. 1 - general view of the keyboard, only keys for entering letters are shown; in FIG. 2 - display on the monitor screen layout of letters of the Russian alphabet; in FIG. .3 - display on the monitor screen layout of letters of the Latin alphabet.

The best option for implementing a utility model

The keyboard of the personal computer contains a housing with a working panel 1, on which there are multi-position keys for entering letters, which are used as T9 programmable buttons. Four keys 2, 3, 4, 5 are for the fingers of the left hand, four keys 6, 7, 8, 9 are for the fingers of the right hand (that is, for the index, middle, ring fingers and little fingers). To create a space, use the 10 key.

When entering a word, the T9 softkey tries to predict which word to type using the built-in dictionary, the most used words are substituted first. Thus, the set of the desired word is significantly accelerated, since it does not require moving fingers from key to key. The lines on which the centers of the keys lie for the index, middle, ring fingers and little fingers of both the right and left hands are symmetrical convex curves, convex outward from the hand. This geometry of the placement of keys for the above fingers more closely matches the anatomy of the hand and increases the usability of the device.

All keys or part of them can be deepened relative to the surface of the working panel 1. This provides a more reliable contact of the finger with the corresponding key.

The following additional keys are provided in the keyboard: key 11 — mode switching, keys 12, 13, 14 — designed to replace one word with another, from a list of words compiled by a computer from a given set of letters. For example, you type the word “side”. Press the keys 4 (ABVG), 6 (MNOP), 3 (IKL) - Fig. 1 ~ computer will create five words: battle, side, howl, battles, ox. Suppose that one of these words - “fight” - is used more often than the other four words in the user's vocabulary, it will be inserted into the text, but at the same time the computer will offer as a possible option another list of 4 words, these words will appear on the monitor screen: 1) side 2) howl 3) fights 4) ox

When you press the key 12 (1 *) corresponding to the word number, the word “side” will be inserted into the text instead of the word “fight”.

The third additional key is designed in such a way that it contains the possibility of several taps. At one clicking on the text will insert the third version of the word, with two clicks - the fourth, etc.

If the word created by the computer corresponds to the intention of the user, then use key 10 - “Space”. The device in a specific example works as follows.

After opening the page for printing and selecting a language, the letters of the selected language, grouped by 4 letters, are displayed on both sides of the page image on the monitor (Fig. 2 and Fig. 3). The arrangement of these groups of letters in order from left to right corresponds to the location on the keyboard of eight keys 2 - 9, designed to print letters.

For example, you need to print the word "thread." Thanks to the use of T9 programmable buttons in the keyboard for entering letters, when you click on these buttons, all possible four-letter variants are sorted and compared with the existing dictionary database. We press the keys 6 (MNOP), 3 (IKL), 2 (RSTU), 9 (LEW): the computer inserts the word “drink” into the text, and below it gives two more possible options, in particular: 1) a thread, 2) Mitya. To replace the word “drink” with “thread”, press the key 12 (1 *) corresponding to the first variant of replacing the word, and the computer replaces the word. Before the next word, a “blank” will be automatically created. If the word "thread" is followed by a punctuation mark, then the "space" will appear after the sign.

Thanks to the additional keys 12, 13, 14, the time required for printing text is saved.

If the computer immediately "guesses" the right word, then to create a space, use the key 10 (Fig.l). If you need to print a word that is not in the computer's memory, for example, the abbreviation BMP, then by pressing key 11 we select the letter-by-letter mode, the so-called ABC. We press the key 4 (ABVG) - 2 times, the key 6 (MROP) - 1 time, again the key 6 (MROP) - 4 times, we get the BMP, we enter this letter combination into the computer memory.

The keys for entering the remaining characters and functions are located in the same way as on a standard keyboard.

Thanks to the use of an element such as the T9 programmable button in the keyboard, the time for entering text (words) is significantly reduced for people who do not know the method of “blind” ten-finger printing, since the need to visually search for the desired key and move fingers from key to key to enter each letter is eliminated one word. Due to the fact that the fingers lie on the keys and smoothly press them, and do not hit them after sudden movements, the likelihood of a professional hand disease is reduced.

Industrial applicability

For the manufacture of the keyboard used common materials and factory equipment, which, according to the applicant, allows us to conclude that this utility model meets the criterion of industrial applicability)) (IA).
