- Abstract
SSVEP based BCI system helps Tetraplegia patients to communicate and control devices based on Steady State Visual Evoked Potentials (SSVEP). Home automation systems are in huge need for the Tetraplegia patients to control home appliances like nurse calling system, lights, and Television sets by using visual cues from a stimulator. A visual stimulator is developed which flares at frequencies 7Hz, 8Hz, 9Hz and 10Hz to control nurse calling device at 7Hz, light at 8Hz, fan at 9Hz and thirsty buzzer at 10Hz. A brain signal acquisition device Emotive EPOC is used to acquire EEG signal under visual stimulus operates at different flickering frequencies. EEG signal is processed by Power spectrum to detect the flickering frequencies of the visual stimulator. These flickering frequencies are used to generate control signals from a microcontroller to control various appliances. Experiments were conducted on 40 subjects with 4 trials on every subject and obtain Maximum Power Frequency (MPF) from the EEG signal. it is found that the Maximum Power Frequency of all the trails across all the suubjects is significant in detection of the flickering frequencies of the visual stimulator with p < 0.001. It is found that the flickering frequencies are detected with the accuracy of 99.98% and specificity and sensitivity of 99.89 and 99.87 respectively.Hence MPF is used to generate control signals to actuate the devices.
