PORTABLE INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

摘要

A portable information processing device includes: a sensor configured to detect physical amount which changes according to a location within predetermined space; a first storage unit configured to store an association between the information of the physical amount and location information; a first processor configured to execute an application program; a second storage unit of which the storage capacity is smaller than that of the first storage unit, configured to store a part of the associations; and a second processor, which is connected to the sensor, configured to acquire the current location from the information of the physical amount detected by the sensor, and the associations stored in the second storage unit; wherein the first processor extracts a part of the associations from the associations stored in the first storage unit according to change in the current location due to movement of the portable information processing device.

1. A portable information processing device comprising:
a sensor configured to detect physical amount which changes according to a location within predetermined space; a first storage unit configured to store an association between the information of the physical amount and location information; a first processor configured to execute an application program; a second storage unit of which the storage capacity is smaller than that of the first storage unit, configured to store a part of the associations; and a second processor, which is connected to the sensor, configured to acquire the current location from the information of the physical amount detected by the sensor, and the associations stored in the second storage unit; wherein the first processor extracts a part of the associations from the associations stored in the first storage unit according to change in the current location due to movement of the portable information processing device, and after transmitting the extracted part of the associations to the second processor, goes into a power-saving state; and wherein the second processor updates information stored in the second storage unit using the part of the associations received from the first processor.
