A P300-based brain-computer interface dataset for television control comprising EEG recordings from 30 healthy subjects performing a visual oddball task. The dataset includes 31-channel EEG data acquired at 500 Hz using active electrodes in a standard 10-20 montage, with target and non-target stimulus classifications for home appliance control applications. Data were collected in an online feedback paradigm with visual flash stimuli presented at 750 ms stimulus onset asynchrony.
