Embodiment Construction
[0021] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] Such as figure 1 , figure 2 Shown, a kind of EEG dialing method comprises the following steps:
[0023] S1. First, the left-hand MI task, the right-hand MI task and the idle state in the motor imagery task are sequentially encoded to form a coding table, which includes twelve sequences with a length of three, and the coding table The sequence in is in one-to-one correspondence with the operation instructions during the dialing operation;
[0024] S2. The user performs the corresponding motor imagery task according to the code list and the operation instruction of dialing the phone, and the brain wave detection device obtains the corresponding EEG signal according to the user's motor imagery task and transmits it to the computer;
[002...

The invention particularly discloses an electroencephalogram dialing method. The method comprises the following steps: S1, sequentially encoding a left-hand MI task, a right-hand MI task and an idle state to form an encoding table, the encoding table comprises twelve sequences with the lengths being three, wherein the sequences in the encoding table are in one-to-one correspondence with operationinstructions in the dialing operation process; S2, enabling a user to perform a motor imagery task according to the coding table and the operation instruction of making the call, and enabling the brain wave detection equipment to acquire a corresponding electroencephalogram according to the motor imagery task of the user and transmit the electroencephalogram to the computer; S3, enabling the computer to carry out classification processing according to the electroencephalogram signals obtained in the step S2 to obtain corresponding operation instructions, thereby achieving automatic dialing ofthe brain-computer. According to the invention, the user can make a call only by thought, the system is of great significance to gun-holding soldiers, busy people and the like, the life self-care ability of patients with dyskinesia is improved, and the burden of families and society of the patients is reduced.
Description
technical field [0001] The invention relates to the technical field of brain-computer interface, in particular to a brain-electric dialing method. Background technique [0002] The basic principle of brain computer interface (brain computer interface, BCI) technology is to use various modern brain activity observation methods to collect brain nerve signals, extract the user's control intention contained in these signals through signal processing and pattern recognition methods, and It is converted into instructions to realize direct manipulation of external devices by ideas. Electroencephalography (electroencephalogram, EEG) is currently the most popular means of monitoring brain signals, which has the advantages of non-invasiveness, high real-time signal performance, good portability, simple and easy-to-use equipment, and relatively low cost. How to provide patients with motor function impairments with a way to directly use ideas to communicate with the outside world or au...
