Abstract

PURPOSE:To obtain the keyboard on which blind touch typing input can easily be mastered and high-speed input is possible by operating keys by easy motion by bending the fingers from their bases while holding the fingers straight. CONSTITUTION:A supporting base 3 while supporting the weight of the hands and arms in operation guide the respective fingers to specific key positions. The 10 keys (1st key) at the tips of the fingers can be operated most easily at a high speed. The keys (2nd key) arranged on the flat sides of the thumbs can also be operated to nearly the same extent with the 1st keys. The keys 2 between the 2nd and 3rd fingers counted from the tips of the fingers other than the thumbs are operated by bending the 3rd joints while the fingers are held straight. Thus, the motion of the fingers required for key operation is simple, so the keys can easily be operated at a high speed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a keyboard used in an information processing device.

[0002]

2. Description of the Related Art At present, most keyboards widely used in word processors, personal computers, computer terminals, etc. basically follow the key arrangement of a mechanical typewriter. Dozens of keys are arranged in a plane, and the fingertip is moved onto the desired key and pressed.

[0003]

The conventional keyboard is
For those who can input by blind touch, high-speed input is possible, but long-term rigorous training is indispensable for their skill acquisition. For this reason, many users have difficulty in high-speed input, and perform visual input in which eye fatigue is particularly significant.

An object of the present invention is to provide a keyboard capable of easily learning blind touch input and capable of high speed input.

[0005]

In order to achieve the above-mentioned object, in the keyboard of the present invention, a hand is placed on the support base (3) and each finger is placed at the position of the fingertip in a bent state. 1
Place the keys (1) one by one. Further, in the thumb, one key (2) is arranged on the ventral side of the finger, and in the fingers other than the thumb, the key (2) is placed inside the finger between the second and third joints counted from the fingertip. ) Is placed one on each finger.

[0006]

The support base (3) supports the weight of the hand / arm during operation and guides each finger to a predetermined key position.

The ten keys (1) of the fingertip (hereinafter referred to as the first key) can be operated most easily and at high speed.

A key (2) (hereinafter referred to as "key" disposed on the ventral side of the thumb)
The second key) is also as easy and fast to operate as the first key.

Second and third counting from the fingertips of fingers other than the thumb
The operation of the key (2) (hereinafter, referred to as the second key) on the inside of the finger between the th and th th is performed by bending the third joint while extending the finger as indicated by the alternate long and short dash line in FIG. Since the finger movement required for key operation is extremely simple, it can be operated easily and at high speed.

[0010]

EXAMPLES Examples will be described below with reference to the drawings. FIG. 1 is a perspective view showing a usage state. As shown in the figure, it is composed of two left and right keyboards, and two keys are arranged three-dimensionally on each finger according to the shape of the finger.

Since the keyboard is symmetrical, the left hand keyboard is shown in the following figures. 2 to 5 are views of the keyboard as seen from four directions.

The support base (3) supports the weight of the hand / arm and guides each finger to a predetermined key position. Therefore, it is desirable that the shape conforms to the shape of the hand as much as possible.

Regarding the position of the first key (1), it is not preferable that the fingers are bent deeply because the fingertips may hit each other or the adjacent key may be erroneously input.

The first key (1) of the thumb is the side of the finger and the second key
The key (2) is operated with the pad of the finger. The movements are almost orthogonal to each other and are therefore easily distinguishable.

The position of the second key (2) of the finger other than the thumb is
It is affected by the position of the base of the first key (1) and the finger, the degree of bending of the finger, and the key stroke. As shown by the broken line in FIG. 2, when the user bends his / her finger and presses the first key (1), the second key (2)
Must not be pressed. In addition, when the finger is extended and the second key (2) is pressed like the one-dot chain line, the first key (1) must not be pressed. If the key switch complies with Japanese Industrial Standards, there is no problem in practical use, but the shorter the keystroke, the better the operation feeling. Also, it is easier for the key pressing pressure to be smaller, which is suitable for high-speed input.

FIG. 6 shows an embodiment of a character array when the main purpose is to input English text. The left and right 10 squares correspond to the 10 keys of the left and right keyboards. From the inside
The upper row corresponds to the first key and the lower row corresponds to the second key in the order of thumb, forefinger, middle finger, ring finger, and little finger.

For example, in [1], if the first key of the left little finger is pressed, "A" is input. In [2],
An item such as "B" that connects two boxes with a broken line indicates an item that is input by simultaneous keying of the two keys. That is, if the first key of the right index finger and the first key of the right ring finger are simultaneously tapped, "B" is input. "●"
Indicates keys to be simultaneously typed. For example,
To input “P”, the first key of the right thumb with “●” and the first key of the right middle finger of “P” may be simultaneously tapped.

[0018]

With a conventional keyboard, blind touch input is difficult because it is difficult to move the keys arranged on a plane by moving a fingertip and striking the keys. Initially,
Even the index finger does not work as expected. Conversely speaking,
That is to say, this exercise is originally an unnatural and difficult exercise for the fingers. Much of the typing skills training is devoted to the development of motor skills to move fingers accurately and quickly. And this training is by no means easy. It is even more difficult for older people.

The keyboard of the present invention requires very simple movements. Even the second key of the fingers other than the thumb operates the keys by a motion that anyone can easily perform, such as "bend your finger from the base with your finger extended." That is, even if it is a first time person, all keys can be operated without looking at the keys. Therefore, if the character arrangement is memorized, blind touch input can be performed from the beginning. By gaining experience in keyboard operation in daily work, etc., faster input is possible without special training.

Further, in the character arrangement, as shown in [1] of FIG. 6, 17 of the 26 alphabetical characters, which are frequently used, can be input with one key. In ordinary English, these 17 characters occupy 90% or more of the whole. Moreover, since all of these keys are keys that can be input at extremely high speed, it is not difficult to imagine that the speed of input during training will be equal to or higher than that of a conventional keyboard.
