摘要： In a biological signal utilizing appliance, an appliance control section controls the appliance in accordance with user's manipulation. At that time, an operation content is presented to a user through an operation presentation section. A biological signal detection section measures user's biological signal and detects from the biological signal the presence or absence of an event-related potential at the time point when time obtained by adding a predetermined shift time of approximately 150 ms to 600 ms elapses after a timing, as a starting point, when the operation content is presented. Upon detection of the event-related potential, a manipulation cancellation section instructs the appliance control section to cancel the presented operation content.

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.
