Electronic device, method for controlling electronic device, and computer-readable medium

A method for controlling an electronic device that is configured to be worn by a user and is provided with a light-emitter that is configured to emit light onto skin of the user and a light-receiver provided at a position for enabling reception of light reflected by the skin of the user when the electronic device is being worn by the user and the light-emitter is emitting the light, the method comprising:

• determining, on the basis of a quantity of light received by the light-receiver, whether the skin of the user satisfies a predetermined darkness condition;
• and
• determining, on the basis of at least the quantity of light received by the light-receiver, whether the user is wearing the electronic device,
• wherein the determination as to whether the user is wearing the electronic device is not performed in response to determining that the darkness condition is satisfied.

A non-transitory computer readable medium storing a program executed by a computer provided in an electronic device that is configured to be worn by a user and is provided with a light-emitter that is configured to emit light onto skin of the user and a light-receiver provided at a position for enabling reception of light reflected by the skin of the user when the electronic device is being worn by the user and the light-emitter is emitting the light, the program causing the computer to function as a controller, wherein the controller:

• performs a skin determination for, on the basis of a quantity of light received by the light-receiver, determining whether the skin of the user satisfies a predetermined darkness condition;
• performs a being-worn determination for, on the basis of at least the quantity of light received by the light-receiver, determining whether the user is wearing the electronic device;
• and
• does not perform the being-worn determination in response to determining in the skin determination that the darkness condition is satisfied.
