Mobile phone interactive system for blind and device thereof

Abstract

The invention discloses a mobile phone interactive system for the blind, comprising a signal acquiring and transmitting device and a mobile phone device. The signal acquiring and transmitting device is arranged on an arm of a person and comprises a signal acquisition module, an analog-to-digital conversion module and a transmitting module, wherein the signal acquisition module is used for acquiring signals generated based on gesture motion; the gesture motion is used as an input command of the mobile communication of the blind; the analog-to-digital conversion module is used for performing analog-to-digital conversion on the acquired signals; and the transmitting module is connected with the analog-to-digital conversion module to transmit the converted acquired signals. The mobile phone device comprises a receiving module, a signal processing module and a function control module, wherein the receiving module is used for receiving the acquired signals; the signal processing module is used for performing gesture recognition processing on the received acquired signals; and the function control module is used for supplying the interactive control with various functions according to a recognition result. The invention can provide a mobile phone which is convenient for carrying and interaction with high efficiency.

Description

technical field [0001] The invention relates to the technical field of gesture recognition and control input in human-computer interaction, in particular to a mobile phone that can be used by blind people. Background technique [0002] At present, with the rapid development of the information society, the mobile phone (mobile phone) has become an indispensable and portable information communication tool in people's daily life. Conventional mobile phone users complete the interaction process through keyboard input and display-based visual information output. This makes it almost impossible for blind people with visual impairment or elderly people with vision loss (hereinafter collectively referred to as blind people) to use conventional mobile phones. [0003] At present, there are a small number of mobile phone products specially designed for blind users. The principle of hand touch recognition for the blind is to engrave and highlight the represented Braille on the keyboar...

Problems solved by technology

However, these input devices must be special keyboards. In order to facilitate the touch of the blind, they are generally large in size and inconvenient to carry. They are very unsuitable for portable digital products the size of ordinary mobile phones.

Even if the size of the touch keyboard is reduced and it is installed on an ordinary mobile phone keyboard for blind people, the too small size will lead to too dense contacts, which is inconvenient for blind users to identify, and the input efficiency is not high
