Brain-computer interface-based telephone system for double-upper limb disabled people

Abstract

A brain-computer interface-based telephone system for double-upper limb disabled people is provided. The brain-computer interface-based telephone system comprises a visual stimulator, an electroencephalography acquisition platform, a system control and data processing unit, a telephone control module and a telephone set; when a user watches a certain LED of the visual stimulator, a steady-state visual evoked potential is generated in a specific area of the brain of the user; the electroencephalography acquisition platform acquires electroencephalography signals in a real-time manner; after being subjected to amplification, filtering and analog-to-digital conversion, the electroencephalography signals are inputted to the system control and data processing unit; the system control and data processing unit processes the electroencephalography signals in a real-time manner so as to detect the frequency of the steady-state visual evoked potential signals, identify the LED display watched by the user, and transmit a command corresponding to the display to the telephone control module; and the telephone control module controls the telephone system and makes the same execute corresponding operation according to the received control command. According to the brain-computer interface-based telephone system for the double-upper limb disabled people of the invention, operation intentions can be expressed through vision, and therefore, body movements of the user can be avoided. The brain-computer interface-based telephone system for the double-upper limb disabled people is advantageous in natural operation, easiness in use, high accuracy in dialing, stable work and almost no need for training users. With the brain-computer interface-based telephone system for the double-upper limb disabled people, basic functions of telephone communication can be realized.

AI Technical Summary

Benefits of technology

This patented method uses an electronic device called Blindness Eye Control (BCE) that helps people who have lost their hands cannot communicate effectively when they don’t want them around because there may be no way to talk back over without having any movement from one side. It allows us to send messages wirelessly instead of just sending numbers like phone rings at home. Users won't feel annoyed about constantly moving outdoors while talking due to lack of eyesight. Overall this makes our devices more efficient than traditional phones.

Problems solved by technology

The technical problem addressed in this patented text relates to improving accessibility to speech impaired individuals who have difficulties controlling themselves while still being able to speak freely because there may also exist other ways like touch screens instead of physical buttons.
