Description

The present invention relates to a tactile sticker attached to a keyboard such as a computer or a typewriter, and an identification character forming body used for displaying alphabet characters in various household and industrial devices, in particular, without looking at the hand. Related to the technique for recognizing alphabet letters by touch.

For example, when inputting characters using a keyboard such as a computer or a typewriter, those who are proficient in keyboard input have a key arrangement such as the QWERTY arrangement in their heads and can read the characters printed on the surface of the keys. It enables so-called blind touch, which allows key input without looking.

On the other hand, it is difficult for those who are not familiar with keyboard input to learn the keyboard layout and the fingering corresponding to the arranged keys, and even if you practice with typing software, it takes time to learn blind touch. It was hanging.

Therefore, a keyboard as shown in Patent Document 1 has been proposed as a keyboard in which a convex portion is provided in the shape of a character corresponding to each key so that the character printed on the key can be recognized by the tactile sensation of a fingertip. (Patent Document 1).

Japanese Unexamined Patent Publication No. 2019-74941

According to the invention described in the cited document 1, a character-shaped protrusion that can identify the input items of each key is provided on the upper surface of the key, and the character can be recognized by touching the key with a fingertip. .. However, although the human fingertips are sensitive, there is no sense until the shape of the character itself, which consists of a complex combination of straight lines and curves, is specified. It is difficult to recognize which character the touched protrusion character is, even if the characters are placed.

On the other hand, Braille has long been used to simplify and display characters by using a combination of dots instead of the shape of the characters themselves. Braille is mainly used in stations and public institutions as a display for the visually impaired, but since the characters are expressed as a combination of only dots, the number of dots and combinations is large, and the Braille itself is complicated. There is a problem that there is. Therefore, it takes time to learn Braille, which is a factor that hinders the improvement of the penetration rate of Braille.

Further, it is desired to press a correct button without looking at the display printed on the button, such as a button for operating a remote controller of a household device or an operation button of a machine tool or the like. Furthermore, even if a container containing a beverage is described as containing alcohol in Braille, if a child or a pregnant visually impaired person cannot correctly judge the indication, he / she mistakenly drinks the beverage containing alcohol. There is a risk of getting pregnant.

As described above, it has been difficult to identify characters by relying only on the tactile sensation of the fingertips by the conventional method.

Therefore, the present application is intended to solve the above-mentioned problems, and provides an identification character forming body capable of easily identifying an alphabetic character only by the tactile sensation of a fingertip.

The present invention provides the following solutions.

The identification character forming body according to the first feature is provided with a convex portion formed in the shape of an identification character in which an alphabetic character is symbolized on a contact surface with a finger in at least a part of a base material. The identification character is a first vertical line element formed between the upper end portion of the frame body and the lower end portion of the frame body, the right end portion of the frame body and the frame body, on the frame body having a substantially rectangular shape in plan view and / or in the frame body. A horizontal line element formed between the left end portion, a second vertical line element formed between the upper end portion of the frame body and the center portion of the frame body, and a second vertical line element formed between the center portion of the frame body and the lower end portion of the frame body. Third vertical line element, a set of first diagonal line elements, a second diagonal line element and a third diagonal line formed so as to intersect between the right end of the frame and the left end of the frame. By any one character element selected from the element and the character element consisting of the element and the point element arranged at the substantially center of the frame and the four corners, or within any three. It is formed by a combination of character elements.

According to the invention according to the first feature, since the identification character is a simplified and symbolized alphabet character, it is easy to imagine the shape of the character by tactile sensation. Moreover, since the identification character is formed by at most three character elements, it is possible to grasp the character by recognizing only the three elements when the convex portion formed in the shape of the identification character is touched with a fingertip. This is possible, and even those who are unfamiliar with blind touch typing or who have acquired visual impairment can identify alphabetic characters by tactile sensation.

In addition, since the character element consists only of straight lines and points and does not use a curve, the identification character can be represented as a simpler character.

According to the present invention, it is possible to provide an identification character forming body capable of easily identifying a character only by the tactile sensation of a fingertip.
