JP2006065438A - Keyboard with mechanism for causing protrusion to protrude from key top using magnetism - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide the keyboard of a computer or the like with a mechanism that allows easily learning touch typing (blind-touch operation). <P>SOLUTION: A mechanism for causing a protrusion to protrude using magnetism under software control is provided at each key top of a keyboard, which is an input device for a computer or the like, to guide the user through touch to a key position to be struck so as to help the user practice pressing desired keys without viewing them. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  A keyboard that is an input device such as a computer can be easily learned by the keyboard mechanism of the keystroke technique without looking at the board surface.

When learning keyboard-type keyboards that are input devices such as computers and typing without looking at the board surface, which is called touch typing or blind touch, from the home position (the key position where each finger is placed when not typing) to other keys It was necessary to rely on each person's experience and feeling to move their fingers. For this reason, it takes time to learn touch typing (blind touch), and there is a drawback that ineffective typing is performed without wearing it.
Moreover, although the keyboard is a contact type input device, there has been no keyboard having an operation guide function based on active and dynamic tactile sense.
The present invention focuses on these points.

  Learning the technique of typing without looking at the keyboard, called touch typing (blind touch), is easily made possible by the mechanism of the keyboard.

  A key top of a keyboard, which is an input device such as a computer, is provided with a mechanism for projecting protrusions by magnetic force by software control, and the position of the key to be pressed next is guided by tactile sensation and the target key is pressed without visual observation. Assist.

  Touch typing (blind touch) technology can be easily acquired in a keyboard which is an input device such as a computer. This improves the key input speed. It leads to prevention of eyestrain, visual loss, stress (so-called VDT syndrome) and the like. Further, there is an effect that the computer can be used more effectively by improving the type technology.

Although the mechanism is not limited to this, FIG. As shown in Fig. 1, for example, a mechanism for pushing out the wire dots of the print head of a dot impact printer is applied to this keyboard, and this is controlled by software. Specifically, use the typing practice software to project the protrusion of the key to be pressed next, and store the protrusion after pressing, or protrude the protrusion of the key at the home position (position where each finger is placed when not keyed) Let
In order to realize this function, the keyboard needs to be connected to the computer through an interface capable of bidirectional communication.
In addition, if miniaturization of the keyboard, power saving, and smooth operation are required, it is desirable that the mechanism for projecting the protrusion is as compact as possible.

As described above, it is used in combination with typing practice software, but in conjunction with finger guidance by touching this keyboard, the keyboard is shown on the screen, and the next key to be pressed and the key to be pressed are displayed as a movie. This is most effective when combined with software.
In addition to practicing touch typing, when explaining functions using function keys and various extended keys in software online manuals (operation manuals that are expanded in sequence on the screen), etc. Usage is also possible.
