Abstract:
A device for controlling equipment comprising:a light projector adapted to project light onto a head of a living body,a light collecting section which collects the light having passed through the head from said light projector,a light measuring section which measures an intensity of the light collected by said light collecting section,a memory section which stores a history of changes of the intensity of the light measured by said light measuring section,a displayed section which displays the intensity of the light measured by said light measuring section, anda control signal generating section which generates a control signal to be supplied to external equipment,wherein said device for controlling equipment is configured such that said control signal is generated when the intensity of the light measured by said light measuring section has increased from a light intensity section B through a light intensity section C to a light intensity section D in succession, and the history of changes of the intensity of the light is reset when the intensity of the light measured by said light measuring section has decreased from the light intensity section B to a light intensity section A,where the light intensity section A is equal to or below a light intensity a,the light intensity section B is equal to or below a light intensity b, but above the light intensity a,the light intensity section C is equal to or below light intensity c, but above the light intensity b,the light intensity section D is above the light intensity c, andthe light intensity c> the light intensity be> the light intensity a.
