Abstract

PURPOSE:To provide facility for the use of visually handicapped persons, by adding a voice output function to an information processing device and improving its key input device. CONSTITUTION:A key input device 1 consists of plural keys where braille points are raised on the surface. A microcomputer (MC) 2 performs not only calculation processing but also information processing for voice output. Words for pronunciation of input data and calculation results are indicated. Since information (pitch, amplitude, reflection factor, etc.) for speech synthesis are written in a voice ROM 4, a speech synthesizing LSI 3 reads out successively synthesized information of words, whose pronunciation is indicated, from the voice ROM 4 to pronounce them.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing device including an audio output device and a key human power device.

BACKGROUND OF THE INVENTION Electronic desk calculators with audio output functionality have been known for some time.

In addition to this voice output function, the inventor of the present application considered providing an information processing device that is convenient even for visually impaired people by improving the key human power device.

An object of the present invention is to provide an information processing device that is easy to use even for visually impaired people.

Other objects of the invention will become apparent from the following description and drawings.

Hereinafter, this invention will be explained in detail together with examples.

FIG. 1 shows a block diagram of an embodiment in which the present invention is applied to an electronic desktop calculator.

The electronic desktop calculator of this embodiment is composed of the following circuit blocks. The key human power device (board) 1 is
The key is made up of a number of keys with Braille embossed on the surface so that even visually impaired people can easily identify the keys. The input information from this key human power device 1 is input to the microcomputer 2, although not particularly limited, and is subjected to calculation processing therein. In addition to the above calculation processing, this microcomputer 2 also performs
It also processes information for audio output. That is, the speech synthesis LSI 3 is instructed to use a word or phrase, which is not particularly limited, to make the input data and calculation results utter. As is well known, the speech synthesis LSI performs speech synthesis processing. Information for this voice synthesis, such as pitch, amplitude 2 reflection coefficient, etc., is written in the voice ROM (read only memory) 4, so the voice synthesis LSI 3 uses the microcomputer 2 to generate the voice. The synthesized information of the instructed words and phrases is read out one after another from the voice ROM 4 and uttered.

FIG. 2(A) shows a surface view of one embodiment of the electric key constituting the key-powered device 1, and FIG. 2(B) shows a sectional view thereof.

In this embodiment, although not particularly limited, Braille, which is most familiar to visually impaired people, is embossed on the surface of the electronic key KEY. Therefore, the numeric keys and funk sync keys can be easily identified by the tactile sensation of the fingertips.

Next, the general operation of this embodiment will be explained.

The arrangement of the keys on the human-powered device is recognized by the sense of touch, and when the key is pressed, a voice corresponding to the key is uttered to perform auditory confirmation while setting the input to be calculated. Then, the calculation process is performed by the microcomputer 2, and the total W result is used to produce the voice.

The electronic desktop calculator of this embodiment does not require special training and can be easily used even by visually impaired people. Note that the above-mentioned vocalization operation for confirming input data is extremely convenient for visually impaired people to practice memorizing the electronic key arrangement of a manual key device.

The invention is not limited to the above embodiments.

The type of characters stamped on the surface of the electric key may be special characters or symbols. Further, the shape may be any shape as long as it can be easily recognized by the sense of touch.

In addition, although it is convenient to perform a series of information processing using a microcomputer, it is not limited to this.
(Programmable Logic Array) or the like may be used.

Furthermore, as an output function, it may be possible to add a display function that can be recognized visually, such as a liquid crystal display, which is convenient for use by people other than visually impaired people.

The present invention can be widely used in information processing apparatuses equipped with a key input device and a voice output function, in addition to the electronic desktop δ1 calculator described above.
