Description

Keypads for Telephones for the Visually Impaired

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keypad of a telephone, and more particularly to a keypad of a telephone for the visually impaired, which displays a predetermined braille type on a key button surface for the visually impaired.

In today's modern society, the use of telephones has become an essential life for modern people, and now it is impossible to live without them.

However, in the use of the above-mentioned telephones, only normal people were provided in reality, and only a handful of people were able to use them. Reference is made to the drawings below as an example.

1 is a plan view showing the keypad structure of a conventional telephone and a mobile phone.

In FIG. 1, the keypad structure of the conventional telephone is implemented by the visually impaired by implementing a predetermined protrusion on the reference numeral 101, which is a key button corresponding to the number '5', but the same function key button or other numerals as the reference portion 102. Since there is no indication on the key button, the position of the numeric key '5' was confirmed, and the position of the remaining key buttons was estimated by the approximation. In this case, however, the user had to memorize all the positions of the key button. In addition, as the performance of the telephone has been developed, various functions have been implemented, and correspondingly, the number of key buttons has increased, but it has become more difficult for the visually impaired to use the developed telephone. For example, reference numerals 103 and 104 of FIG. 1 indicate a function key button of a conventional mobile phone, but it is more difficult to use the visually impaired person.

An object of the present invention for solving the above problems is to display a braille type on the upper surface of the key button of the telephone keypad, so that the visually impaired can conveniently use the phone.

In order to achieve the above object, the present invention is characterized by displaying a predetermined braille on the upper surface of the key button on the keypad of the telephone, and allows the visually impaired to conveniently use the telephone through the braille.

1 is a plan view showing the keypad structure of a conventional telephone and a mobile phone.

2 is a plan view showing a keypad structure of a telephone and a mobile phone according to an embodiment of the present invention.

3 is a view showing braille corresponding to numbers and letters applied to the present invention.

4 is an international standard abbreviation braille table implemented in the present invention,

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a plan view showing a keypad structure of a telephone and a mobile phone according to the date and time of the present invention.

Referring to Fig. 2, reference numeral 201 denotes a key button corresponding to the numeric key '1' on the keypad of a general telephone, in addition to the key buttons of numbers 0 to 9 on the keypad of the telephone. . In the present invention, a braille type corresponding to each number is formed on the top surface of each key button so as to easily identify the visually impaired person on the top surface of the numeric key button, or a groove is displayed. Reference numeral 202 denotes a special function key button on a keypad of a general telephone, and corresponds to the '*' and '#' marks to form grooves and protrusions in the shape so that the visually impaired person can easily identify. Similarly, Figure 2 shows an example of the present invention applied to a general mobile phone. Reference numeral 203 denotes 'Snd' as a transmission key of a general mobile phone, and in the present invention, a braille-type projection corresponding to the letter 'S' at the top of the key button so that the visually impaired person can easily recognize the key. Form a groove. Similarly, the power key 'Pwr' also forms a braille-shaped projection or groove corresponding to 'P'. Reference numeral 204 denotes a function key used in a mobile phone, and is used to adjust the volume of the mobile phone and to select a menu from a function menu, thereby serving as UP / DOWN. The upper portion of the 'UP' key button forms a 'U' braille type, and the upper portion of the 'DOWN' key button forms a 'W' shaped braille protrusion or groove. In other words, the function abbreviation of the English abbreviation determines in advance one of the representative alphabetic characters of the alphabet and displays it in braille. In addition, another function is added to determine the representative alphabet letters on the top of the corresponding key button to display in braille.

3 is a view showing braille corresponding to numbers and letters applied to key buttons according to the present invention described above.

Referring to Figure 3, it shows a braille type corresponding to the numbers and special symbols, letters corresponding to the key button of a general telephone or mobile phone applied to the present invention. Numeric key buttons represent the braille types, special characters implement the braille type corresponding to the character, and function key buttons select the representative alphabetic characters of the English alphabet representing each function and display them in braille. If there is a key button of other functions implemented in each phone or mobile phone, the corresponding representative alphabet letters are embodied in braille.

Figure 4 shows the international standard abbreviation braille table implemented in the present invention.

Referring to FIG. 4, braille corresponding to Korean, numerals, English, and punctuation marks appears, and the braille is implemented and used in key buttons of the mobile phone or the phone.

As described above, the present invention displays the braille type on the upper surface of the key button implemented on the keypad of the phone so that the visually impaired person can identify the key button, so that the visually impaired person can easily use the phone.
