DETERMINATION SYSTEM, CONTROL SIGNAL OUTPUT SYSTEM, REHABILITATION SYSTEM, DETERMINATION METHOD, CONTROL SIGNAL OUTPUT METHOD, RECORDING MEDIUM, AND ELECTROENCEPHALOGRAM SIGNAL ACQUISITION SYSTEM
A determination system includes a mastoid electrode that is located on a left mastoid of a user when an intention of the user to move a portion on a right side of a body of the user is detected and that is located on a right mastoid of the user when an intention of the user to move a portion on a left side of the body of the user is detected an ear hole electrode that is located in an ear hole of the user an electroencephalogram signal measurer that obtains a voltage between the mastoid electrode and the ear hole electrode and a determiner that determines whether or not a change in the voltage includes the intention to move the portion on the right side of the body or the intention to move the portion on the left side of the body.
