Abstract
An information processing device includes a global positioning system (GPS) device configured to execute position calculation processing based on data received from a satellite; a power supply controller configured to control power supply to the GPS device; and a device controller configured to monitor a state of use of the information processing device by a user, to calculate a use frequency of the information processing device per unit time, and to cause the power supply controller to intermittently supply power to the GPS device if the calculated use frequency is lower than a predefined threshold value.
Claims13
An information processing device, comprising:
- a global positioning system (GPS) device configured to execute position calculation processing based on data received from a satellite;
- a power supply controller configured to control power supply to the global positioning system device;
- and
- a device controller configured to monitor a state of use of the information processing device by a user, to calculate a use frequency of the information processing device per unit time, and to cause the power supply controller to intermittently supply power to the global positioning system device if the calculated use frequency is lower than a predefined threshold value.
A power supply control method in an information processing device including a global positioning system (GPS) device, the method comprising:
- monitoring a state of use of the information processing device by a user and calculating a use frequency of the information processing device per unit time;
- and
- controlling power supply so that power is intermittently supplied to the global positioning system device if the calculated use frequency is lower than a predefined threshold value.
A computer program for causing execution of a power supply control method in an information processing device including a global positioning system (GPS) device, the power supply control method comprising:
- monitoring a state of use of the information processing device by a user and calculating a use frequency of the information processing device per unit time;
- and
- controlling power supply so that power is intermittently supplied to the global positioning system device if the calculated use frequency is lower than a predefined threshold value.
