[0023] The method of destination selection based on EEG signals described in this invention is particularly suitable for people with mobility impairments. Those skilled in the art can further expand other driving assistance systems based on the basic equipment and principles of this invention.
[0024] The basic principle of the present invention is that when the user needs to select a destination, he does not need to perform physical or voice actions, but only needs to look at figure 2 Shown is the destination to be selected in the stimulus display module 201 ( figure 2 Medium gray letter AI), the corresponding P300 waveform will appear in the corresponding area of the brain. The EEG signal on the scalp at the corresponding position will be collected through the EEG acquisition module and the EEG signal will be analyzed and processed through the EEG analysis and processing module. , Get the real intention of the user; then, look at figure 2 As shown in the stimulus display mo...
