Electronic apparatus and method of detecting tap operation

An electronic apparatus comprising:

• a setting unit that sets a sampling frequency for acceleration detection of an acceleration sensor;
• a processing unit that performs a determination of a tap operation based on sensor information from the acceleration sensor;
• and
• a wearing determination unit that determines a wearing state of the electronic apparatus,
• wherein, when the electronic apparatus is determined to be in a non-wearing state, the setting unit sets the sampling frequency to F1 as a lower frequency than the sampling frequency F2 before determination.

An electronic apparatus comprising:

• a setting unit that sets a sampling frequency for acceleration detection of an acceleration sensor and a threshold value for determination of a tap operation;
• and
• a processing unit that performs a determination of the tap operation based on sensor information from the acceleration sensor,
• wherein the setting unit sets the sampling frequency to F1 and sets the threshold value to Th1 in a first set mode of the acceleration sensor, and sets the sampling frequency to F2 as a higher frequency than F1 and sets the threshold value to Th2 as a larger value than Th1 in a second set mode of the acceleration sensor.
