Abstract

The invention relates to the technical field of brain computer interfaces, in particular to an idea collection device, telephone terminal and system based on a brain computer interface. The collection device comprises a head wearing ring, the middle of the head wearing ring is provided with a stretching elastic plastic member provided with an EEG signal acquiring unit, a signal preprocessing module and a wireless transmitting module which are connected electrically and sequentially; the EEG signal acquiring unit is composed of four electrodes, including one reference electrode and three EEG signal acquiring electrodes; the reference electrode and the EEG signal acquiring electrodes are fixed to the stretching elastic plastic member through electrode caps, are arranged according to an 'international, 10 / 20 standard lead system' and are connected to the signal preprocessing module. Signal processing and analysis are simplified, the lead number is decreased, and the equipment complexity is lowered.

Description

technical field [0001] The invention relates to the technical field of brain-computer interface, in particular to an idea collection device, telephone terminal and system based on the brain-computer interface. Background technique [0002] Voice communication is the main mode of modern communication, but almost all telephones are designed for people with healthy limbs (especially upper limbs), and telephones need to be manually dialed before they can be used normally. However, in today's society, people with upper limb dysfunction have gradually formed a huge group. They are unable to use existing telephones to communicate due to disabilities of both upper limbs or neuromuscular diseases (such as amyotrophic lateral sclerosis, brainstem stroke, cerebral palsy, brain or spinal cord injury, etc.). [0003] The development of brain-computer interface (Brain-computer interface, BCI) technology, electronic technology and biomedical science provides a feasible method to solve the...
