Electroencephalogram interface system, electroencephalogram interface providing apparatus, method of operating electroencephalogram interface, and program

An electroencephalogram interface providing apparatus comprising:

• a selection flicker control section for flickering each of a plurality of options on a presentation section, the plurality of options being manipulable items concerning manipulations of a device;
• an inference section for inferring one option corresponding to a desired manipulation of the user by utilizing an event-related potential of an electroencephalogram contained in an electroencephalogram signal from the user measured by a biological signal detection section, the event-related potential being based on the flickering of each of the plurality of options as a starting point;
• a confirmation flicker control section for effecting confirmation flickering of the one option inferred;
• and
• a determination section for determining whether the inferred option corresponds to the desired manipulation of the user by utilizing an event-related potential of an electroencephalogram contained in the electroencephalogram signal, the event-related potential being based on the confirmation flickering of the one option as a starting point, wherein
• the electroencephalogram interface providing apparatus causes an output section to execute a process which is in accordance with a result of determination by the determination section.

A method of operating an electroencephalogram interface system, comprising the steps of:

• presenting a plurality of options to a user, the plurality of options being manipulable items concerning manipulations of a device;
• flickering each of the plurality of options;
• measuring an electroencephalogram signal from the user;
• inferring one option corresponding to a desired manipulation of the user by utilizing an event-related potential of an electroencephalogram contained in the electroencephalogram signal, the event-related potential being based on the flickering of each of the plurality of options as a starting point;
• effecting confirmation flickering of the one option inferred;
• determining whether the inferred option is an option corresponding to the desired manipulation of the user by utilizing an event-related potential of an electroencephalogram contained in the electroencephalogram signal, the event-related potential being based on the confirmation flickering of the one option as a starting point;
• and
• executing a process which is in accordance with a result of determination by the determination step.
