Description

A touch screen for visually impaired mobile phone capable of touch recognition and its response method

technical field

The invention relates to the technical field of mobile phone touch screens, in particular to a touch-recognizable touch screen for a visually impaired mobile phone and a response method thereof.

Background technique

At present, low-vision patients, especially blind people, mainly rely on hearing and touch to live and work. Taking mobile phones as an example, they usually use general-purpose keyboard-type mobile phones (only a few styles) with blind TTS screen reading software installed, which can make calls, send and receive text messages, and so on. However, each button of a universal keyboard type mobile phone is relatively small, and the buttons cannot be identified in Braille. It is very difficult for the blind to perceive the mobile phone keyboard, the probability of input error is high, and it is very inconvenient to operate. For modern high-end intelligent terminals such as smartphones and tablet computers that are increasingly popularized, almost all of them use touch screens and have no buttons. Low-vision patients, especially blind people, cannot accurately identify the content of the corresponding buttons on the touch screen, so they cannot use them. Smartphones and tablets are gone, making it impossible to enjoy modern civilization.

At present, using the smart phone platform and the super large display screen of the touch screen mobile phone, we have further developed more functions that meet the needs of people with low vision, especially blind users. The super large display screen has three advantages: 1. For the visually impaired, you can increase the zoom level to see more content and larger images; 2. Put the simplified button definition on the super large The area is more suitable for finger operation and reduces the chance of input errors; 3. You can customize a better touch-operated keyboard.

The Chinese patent application whose publication number is CN 101909100A discloses "a kind of braille mobile phone, which is characterized in that the buttons of the mobile phone are provided with braille, and the mobile phone is provided with buttons for directly dialing emergency calls, as well as buttons for querying date and address, The phone is equipped with a high-power speaker." But what this document discloses is only common button mobile phone.
