JPS61243558A - Electronic computer for blind man - Google Patents

Abstract

PURPOSE:To make it possible that even a blind man uses an electronic computer by providing an input part having input keys which can be discriminated tactually, an operation part which performs a designated operation on a basis of input data, and an output part which outputs the operation result in such form that the blind man can recognize the operation result. CONSTITUTION:An input part 1 is equipped with a ten key and function keys which are provided which braille so that even a person who loses his eyesight or a person with a weak eyesight can discriminate tactually classifications of input keys. Data inputted from the input part 1 is sent to an operation part 2 and is subjected to designated operation. The operation result is sent to an output part 3 and is displayed on a display device 4 where the operation result can be recognized visually, and simultaneously, the operation result is converted to an audio signal by a sound synthesizer 5 and is sent to a speaker 6 and is outputted as sounds which can be recognized by hearing. Further, the operation result is outputted to a braille output device 7 on which the operation result can be recognized tactually. Thus, even the blind man uses the electronic computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic calculator, and more particularly, to an electronic calculator that can be used even by blind people.

[Conventional technology]

Conventional electronic calculators simply have an input section with an input key printed or engraved with Arabic numerals or alphabento;
It consisted of a calculation section that performs a specified calculation based on input data from the input section, and an output section that outputs the result of the calculation in a visually perceivable format.

[Problem that the invention seeks to solve]

The above-mentioned conventional electronic calculators have a structure that includes an input section with an input key that requires visual identification, and an output section that requires visual recognition of the calculation result, so it is difficult to lose sight. The drawback is that it is impossible or extremely difficult for people with very poor eyesight to use it.

[Means for solving problems]

The electronic calculator for the blind of the present invention includes an input section equipped with an input key that can be identified by touch, a calculation section that performs a specified calculation based on input data from the input section, and a calculation section that performs a specified calculation based on the input data from the input section. and an output section that outputs the output in a format that is recognizable even to blind people.

〔Example〕

Next, the present invention will be explained with reference to all the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The input unit 1 is equipped with, for example, a numeric keypad and function keys inscribed with Braille so that even people with poor eyesight or very poor eyesight can identify the type of input key by touch.

The data input from the input section 1 is sent to the calculation section 2,
Necessary calculations are performed based on the input data here. The data being input from the input unit 1 and the results of calculations performed based on the input data are sent each time to the output unit 3 and displayed on the display 4 that allows visual recognition.
At the same time, the signal is converted into an audio signal by the speech synthesizer 5, and sent to the speaker 6, where it is output as audio that enables auditory recognition, and also to the Braille output device 7, which allows tactile recognition. Output.

〔Effect of the invention〕

As explained above, the electronic calculator of the present invention includes a human power unit equipped with an input key that can be identified by touch, and an output unit that outputs in a format that can be recognized by touch and hearing. It is effective and can be easily used even by people who lack eyesight or have very poor eyesight.
