KR-20260066974-A - Keypad for disabled people

Abstract

The present invention discloses a secure keypad for the visually impaired and an input method on the secure keypad, wherein vibrations are provided at the boundaries of each area through mapping of a screen on a user terminal such as a smartphone with a Braille area for the visually impaired, thereby enabling the user (visually impaired) to know the location of the Braille character to be input, and the screen appears black to ensure efficiency in Braille-based information input and prevent others other than the user from knowing the relevant information, and additionally provides encryption-based security. A secure keypad input method for a visually impaired person may include the steps of: dividing a portion of a screen into n braille areas (where n is a natural number greater than or equal to 6) and assigning a separator to each of the n braille areas; identifying an event braille area among the n braille areas where a touch-down and a touch-up after a move occur on the screen; generating bit data using the separator assigned to the event braille area; and inputting text identified by the bit data onto the screen.

Description

Keypad for disabled people The present invention relates to a secure keypad for the visually impaired and an input method on a secure keypad, wherein vibrations are provided at the boundaries of each area through mapping of a screen on a user terminal such as a smartphone with a Braille area for the visually impaired, thereby enabling the user (visually impaired) to know the location of the Braille character to be input, and the screen appears black to ensure efficiency in Braille-based information input and prevent others other than the user from seeing the relevant information, and additionally provides encryption-based security. Thanks to recent technological advancements, smartphones are easily used by many people, and most smartphones allow for information input through touch methods as well as feedback such as vibration, sound, and visual effects. However, visually impaired individuals face inconveniences in using such smartphone input methods. There is a disadvantage in that Braille-based information input is difficult for the visually impaired, and visual effect-based input and feedback methods may be vulnerable to over-the-shoulder attacks. Furthermore, most smartphone applications do not provide the necessary security and countermeasures against such attacks. Therefore, input means and methods capable of simultaneously providing input efficiency and security for the visually impaired in a smartphone environment are required. FIG. 1 is a drawing showing the overall shape of a horizontal keypad for the disabled according to an embodiment of the present invention. FIG. 2 is a drawing showing the front portion of a horizontal keypad for the disabled according to an embodiment of the present invention. FIG. 3 is a drawing showing the overall shape of a vertical keypad for the disabled according to an embodiment of the present invention. FIG. 4 is a drawing showing the front portion of a vertical keypad for the disabled according to an embodiment of the present invention. Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or restricted by the embodiments. Identical reference numerals in each drawing indicate identical components. FIG. 1 is a drawing showing the specific configuration of a security keypad for a visually impaired person according to an embodiment of the present invention. The security keypad (100) for a visually impaired person according to the present invention may be configured to include a processing unit (110), a verification unit (120), a generation unit (130), and an input unit (140). Additionally, the security keypad (100) may be configured to additionally include an execution unit (150) and a vibration unit (160) according to an embodiment. First, the processing unit (110) can divide a portion of the screen into n braille areas. That is, the processing unit (110) serves to divide the central portion, which occupies most of the screen and where finger touches on the screen mainly occur, into multiple braille areas. Here, the number of braille areas n divided can be set to a natural number of at least 6, taking into account 6-dot braille (BANA code). After dividing the braille areas, the processing unit (110) can assign a separator to each of the n braille areas. That is, the processing unit (110) maps a separator that independently separates each braille area to each braille area, so that, for example, when a touch-up occurs in a specific braille area, a user who may be visually impaired can recognize the braille they wish to input based on the separator mapped to the specific braille area. In the assignment of the above-mentioned separators, the processing unit (110) may sequentially assign separators with different values to each of the n braille areas. For example, under the condition that the braille area is divided into 6, the processing unit (110) may prepare 6 numbers from 1 to 6 and use them as separators assigned to each of the 6 braille areas. Additionally, the processing unit (110) can switch the entire screen to black in conjunction with the touchdown, so that the event braille area where the touchup takes place is not exposed. That is, as the user touches the screen to input braille, the processing unit (110) processes the arrangement of the braille area, etc., by covering it with black, so that even if a third party outside sees the user touching the screen to input braille, they cannot accurately perceive the braille area where the touchup actually takes place. The verification unit (120) can verify the event braille area where a touchdown and a touch-up after a move occur on the screen among the n braille areas. That is, the verification unit (120) reads the manner in which the user touches on the screen and identifies the braille area where the touch-up actually occurs as the event braille area where the event occurred. In verifying the ab
