DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboardless keyboard which can input keying data based on a key arrangement of a virtual keyboard in a word processor, a personal computer, various information terminals, game machines and the like.
About computers.

[0002]

2. Description of the Related Art Generally, various computers for information processing are provided with a keyboard on which various keys for inputting information data are arranged. In this case, the keyboard is provided separately from the computer main body, or is an integral type in which keys are arranged on the computer main body.

[0003]

However, whether the keyboard is a separate type or an integrated type, the key arrangement space and weight occupy a considerable amount in the computer main body. There is.

[0004] In recent years, due to the penetration of computers in daily life, the operation of tapping various input keys on a keyboard has also become intensified, and many users have complained of tendonitis at the fingertips of both hands.

Accordingly, an object of the present invention is to reduce the size and weight of a computer main body by using a so-called keyboard-less system in which an input key and a key-arranged keyboard provided in various computers are not installed. Another object of the present invention is to provide a keyboardless computer which can protect a user from tendonitis by reducing the key operation of the user's finger.

[0006]

A keyboardless computer according to the present invention is provided with a myoelectric potential detecting means for detecting an action potential of each finger tapping operation based on a virtual keyboard key arrangement on both wrists of a user. The computer body is configured to process keying data based on the action potential detection signal from the myoelectric potential detection means. In this case, the myoelectric potential detection means can be configured to include a keying data conversion unit that converts the action potential detection signal into keying data. Also,
The computer main body is provided with a key input data input unit into which key input data from the key input data conversion unit is input. The transmission of the keying data to the keying data input unit can use an infrared LED provided in the keying data conversion unit.

Therefore, with such a structure, the computer body is not provided with a conventional arrangement of various keys or a keyboard, so that the installation space for these keys is reduced in size and the weight is reduced. At the same time, the user is only required to perform a slight keystroke operation of the finger based on the key arrangement of the virtual keyboard, and the burden of the conventional keystroke operation is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A keyboardless computer according to an embodiment of the present invention will be described below in detail with reference to the drawings.

As shown in FIG. 1, the keyboardless computer of the present embodiment can be applied to a computer main body 1 in various computer systems such as a personal computer. In such a personal computer or the like, the computer main body 1 is not provided with various input keys based on the conventional JIS standard or the like, and is not provided with a keyboard in which various keys are arranged. A key input data input unit 2 is provided in a suitable portion of the computer main body 1 in place of a conventional key input signal input port. Therefore, in the computer main body 1, the keying data input unit 2 receives the information data transmitted from the external peripheral device,
It will be processed by the built-in electronic control unit.

On the other hand, the user of the computer main body 1 puts a wristband 5 on both wrists 3 and 4 during the information input operation.
5 is wound and attached. Each thumb 3a (4a) of both hands and the index finger 3b (4)
b) When the middle finger 3c (4c), the ring finger 3d (4d), and the little finger 3e (4e) are pressed, a myoelectric potential detecting means 10 for detecting the action potential of the fingertip muscle is mounted.

The myoelectric potential detecting means 10 has a plurality of myoelectric sensors 11 fixed to the wrist bands 5, 5 of both wrists 3, 3, respectively. These myoelectric sensors 11
Is the thumb 3a (4a) of each hand and the index finger 3b (4
b), when the middle finger 3c (4c), the ring finger 3d (4d), and the little finger 3e (4e) are keyed, their action potentials can be detected. Also, the myoelectric potential detecting means 10
Has a tapping data conversion unit 12 that transmits and receives the action potential detection signal of each finger detected by the myoelectric sensor 11 between the left wrist 3 and the right wrist 4 and converts it into keying data. . The keying data conversion unit 12 includes a conversion data transmission unit 13 mounted on the left hand 3 and a conversion data reception unit 14 mounted on the right wrist 4. Further, the myoelectric potential detecting means 10 is provided on one of the left wrist 3 and the right wrist 4,
In the case of the present embodiment, the keying data converter 12
Is provided with a keying data light emitting section 15 for transmitting the keying data converted in step (1) to the keying data input section 2 of the computer main body 1 described above.

An infrared LED (light emitting diode) is used for each of the conversion data transmitting / receiving sections 13 and 14 provided between the two wrists 3 and 4 and the keying data emitting section 15 provided on the right wrist 4 side. Can be. Therefore, a light receiving unit that receives infrared data emitted from the keying data transmitting unit 15 is arranged as the keying data input unit 2 provided on the computer main body 1 side. Thus, optical communication is performed between the computer main body 1 and the user.

The user uses a virtual keyboard 20, for example, appropriately printed on the surface of a board or the like, and uses, for example, various keys 21, 2 arranged in a two-dimensional coordinate system of X and Y.
2, 23... Are the fingers 3a (4a) of the both wrists 3, 4, the index finger 3b (4b), the middle finger 3c (4c), and the ring finger 3d (4).
d) and key operation can be performed with the little finger 3e (4e). The user can select various keys 2 on the virtual keyboard 20.
Are operated by a slight touch operation, so that the burden on the wrist or the like as in the conventional keyboard operation can be greatly reduced.

The action potential due to the tapping operation is detected by the myoelectric potential detecting means 10, and the detected action potential detection signal of each finger is converted into keying data by the conversion data transmitting / receiving units 13 and 14. The converted keying data is
Light emission is transmitted from the key input data light emitting section 15 on the right wrist 4 side to the key input data input section 2 of the computer main body 1. The computer body 1 processes the received keying data in the same manner as the conventional information signal processing from a keyboard.

[0015]

As described above, the keyboardless computer according to the present invention has no arrangement of various input keys on the computer main body and does not require a separate keyboard as in the prior art. Small size and light weight can be realized. In addition, since the keying operation of the user is performed based on the virtual keyboard, the burden on the key input operation up to that time is reduced, which is effective in preventing tendonitis and the like.
