    Abstract: A hand driving device includes first to third stepping motors, a driving circuit, a magnetic sensor, and at least one processor. The first to third stepping motors move hands. The driving circuit drives the first to third stepping motors. The processor controls a magnetic sensor, based on movement of the first to third stepping motors, determines whether or not the driving circuit has rotated the stepping motors while the magnetic sensor does not perform measurement, and, when determining that the motors have not rotated, makes the magnetic sensor start measurement.

    Abstract: The present disclosure provides as electronic device, a calibration method, and a program, which can suppress the power consumed by calibration of a geomagnetic sensor while maintaining high convenience. The electronic device operable in a plurality of types of usage modes including an activity mode associated with a predetermined activity, includes: a geomagnetic sensor that detects geomagnetic data; one or more processors; and one or more memories storing a program to be executed by the one or more processors. The program causes the one or more processors to perform the following: starting calibration of the geomagnetic sensor when it is determined. that the electronic device is operating in the usage mode of the activity mode associated with the predetermined activity.

    Abstract: An electronic timepiece includes a turnable hand and a processor that controls a turn of the hand. When the processor performs a rapid shift of the hand to a set target position, the processor performs a control of a damping of reciprocation of the hand in which the hand performs a predetermined reciprocation about the target position as a reference position and gradually decreases an amplitude of the reciprocation thereof during the rapid shift.

    Abstract: An electronic device includes a notifier and a processor. The notifier is capable of performing notification in a plurality of notification modes including a first notification mode in which the notifier outputs sound and a second notification mode in which the notifier outputs not sound but other. The processor determines whether the electronic device is being used underwater, and in response to determining that the electronic device is being used underwater, switches a notification mode of the notifier from the first notification mode to the second notification mode in a case where the first notification mode is set as the notification mode of the notifier.

    Abstract: Power consumption due to failed automatic calibration is suppressed. An electronic watch is provided with a magnetic sensor, a processor for performing calibration of the magnetic sensor and controlling two or more function modes, and an acceleration sensor for sensing movement of a user. The processor determines whether a state of movement sensed by the acceleration sensor is a calibratable state in which calibration of the magnetic sensor can be performed, performs discrimination of a function mode being executed among the two or more function modes, and performs the calibration of the magnetic sensor when (i) the state of movement sensed by the acceleration sensor is the calibratable state and (ii) the function mode is not a non-default mode, the non-default mode being a function mode executed in accordance with an operation by the user.

    Abstract: An information processing device includes, at least one processor that derives frequency characteristics of time-series data of a measurement result by an acceleration sensor and determines whether the time-series data indicates a running/walking state in accordance with whether all determination conditions including at least a first condition and a second condition are satisfied, the first condition being a condition that a frequency having maximum intensity in the derived frequency characteristics is equal to or higher than a lower limit frequency set in advance, and the second condition being a condition that at least one of the frequency having the maximum intensity or a frequency having second largest intensity in the frequency characteristics falls within a range equal to or higher than the lower limit frequency and equal to or lower than an upper limit frequency set in advance.
