摘要： A brain wave interface (IF) is started up using user's brain wave signals. A brain wave IF system comprises a brain wave measuring portion for measuring brain wave signals, a function controlling portion which analyzes an event-related potential contained in brain signals and outputs a function control signal for controlling the function of the apparatus based on the analysis results, and an output portion for outputting the function control signal. A start-up device comprises a start-up judging portion and a stimulus-attention judging portion. The start-up judging portion transmits, to the output portion, a stimulus control signal for controlling presentation/extinction of a visual stimulus which is a single item in the output portion when the brain wave IF system is not working, and compares a value of a P200 component of the event-related potential starting on a presentation timing of a visual stimulus out of the brain wave signals acquired from the brain wave measuring portion with a predetermined threshold value to determine whether or not to output a start-up trigger to the function controlling portion based on the comparison results. The stimulus-attention judging portion judges whether the user is paying attention to the visual stimulus based on an N100 component of the event-related potential starting on the presentation timing of the visual stimulus and makes the start-up judging portion start processing according to the judgment results. The brain wave IF system is started by the start-up judging portion outputting the start-up trigger.
