Description

A device for entering commands into a computer relates to the field of computer technology, in particular to peripheral data input devices, and can be used to quickly and reliably enter service commands for switching lowercase and capital letters and switching the input language.

Currently, several generally accepted standards are used for keyboards of various devices. For desktop computers, the standard is the IBM PC-XT keyboard, with a QWERTY layout, its principle is partially transferred to laptops. The principle of operation of the keyboard is that the controller built into it monitors the state of pressing and releasing one or more keys, sequential or simultaneous, and transmits messages about the current state to the device’s processor.

The closest set of essential features can be considered a multilingual keyboard system described in the source US 5387042, 02/07/1995, B41J 5/00, which contains a set of standard keys, as well as several multimedia keys and keys designed for the user to work with many languages, encodings and keyboard layouts. When working on such a keyboard, using the so-called ten-finger blind method, the operator actually uses only eight fingers, since the natural physiological movement of the thumbs allows you to press only the space bar.

The purpose of the claimed utility model is to provide a technical result to increase the ergonomics of the operation of the keyboard by providing the ability to move the fingers along a more natural physiological path of the fingers.

Today, there are many millions of laptops and desktop personal computers equipped with standard keyboards.

The difference of the proposed utility model is the expansion of the scope, this compact device makes it possible to increase the speed of inputting information using laptops and standard keyboards of desktop computers that are currently held by users. Thus, the scope of the computer keyboard is expanded.

The utility model proposed in the application provides greater usability, which, in turn, increases the speed of inputting information.

To characterize the input device, and in particular the keyboard, the relative position of the elements is of great importance.

The time for entering a character from the keyboard is T = S / V, where V is the speed of movement of the fingers is a subjective quantity. Therefore, objectively, the time a character is entered for any person depends only on the path S traveled with the tip of the finger from its original position to the desired character. Time T the less, the smaller the distance from the starting position (figure 1) to the desired sign. Thus, although the advantage with each stroke is hundredths of a second, but, in general, the speed of data input is increased, which objectively increases the overall efficiency of using a computer keyboard. The technical result is manifested objectively, regardless of the individual characteristics of the user.

The proposed utility model is characterized in that two functional control keys are located in a position selected from the condition that they can be pressed with the thumbs when a row of keys of the middle line of the computer keyboard is used as the starting position for the index, middle, ring fingers and little finger. The right function key 1 (figure 1) provides switching alphabets (RUSSIAN, Latin), and the left 2 (figure 1) switches lowercase and uppercase letters.

The ultimate goal of any input device is to increase the speed of inputting information, and this, in turn, depends on the convenience of using the input device. The purpose of the claimed utility model is to provide a technical result to increase the ergonomics of keyboard operation by providing the ability to move fingers along their more natural physiological trajectory. The goal is achieved as follows: a small-sized device for entering commands into a computer is located outside the standard keyboard in the most convenient way for the user (Fig. 1) and contains a housing, on the top of which are located the alphabet switching key 1 (Fig. 2) and the lowercase and uppercase letters 2 (figure 2). On the right side of the case there is a switch that provides a choice between ALT / SHIFT and CTRL / SHIFT 3 (figure 2), this switch allows you to work regardless of the setting of the way to switch alphabets in the computer. Inside the housing is located connected to the keys of the controller 5 (Fig.3). The controller using cable 6 (figure 2) through the USB connector 7 (figure 3) is connected to the computer processor. The base of the housing has an anti-slip surface 8 (figure 2).

The essence of the utility model is illustrated by drawings, which show:

Figure 1. The working position of the device for entering commands into the computer.

Figure 2. General view of the device for entering commands into a computer.

Figure 3 Connection diagram of the controller and control keys.

Combining the keyboard with the proposed utility model allows you to create a combined desktop computer control device that significantly improves the working conditions with it and increases the input speed. This is especially noticeable when working with large amounts of text input and browsing the Internet.
