Abstract: A control device includes: an output unit that outputs a signal for prompting an electronic device to execute a predetermined operation; a function switch unit that includes a plurality of switches each having a contactor formed such that at least a portion of the contactor is elastically displaceable in a predetermined direction; and a label body that has a display part and a protruding part protruding from the display part, the label body being mounted in a state where the protruding part is inserted into a hole in a housing and the display part is positioned on an outside of the housing. The protruding part of the label body determines a combination of open or closed states of the plurality of switches. The predetermined operation is determined according to the combination.

Abstract: An eyewear device which adjusts a transmitted light amount to a left eye and a right eye of a viewer to perform an assistance operation, which assists the viewer in viewing images so that the viewer stereoscopically perceives the images, comprising: a receiver configured to receive a synchronization signal in synchronization with display of the images; and a controller which analyzes a signal configuration of the synchronization signal after power supply is started for the assistance operation, and switches a control mode between a first control mode and a second control mode, which is different from the first control mode, based on an analysis result of the signal configuration.
