INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM

摘要

When an amount of a change of a temperature sensor output value is greater than a threshold, the occupation ratio is updated. When the amount of the change of the temperature sensor output value is equal to or smaller greater than the threshold, the occupation ratio is not updated and the background temperature is updated by using the occupation ratio at the time one sampling period before. When a difference between the temperature sensor output value and the background temperature calculated in this way becomes equal to or smaller than a threshold for an absence stated determination, it is determined an user is in an absence state.

主权项

1. An information processing apparatus, comprising:
an acquisition unit configured to acquire an output from a temperature sensor capable of outputting a signal depending on a temperature within a detection region; an occupation information storage unit in which information relevant to a percentage of a detection object in the detection region is stored as occupation information; a background temperature information storage unit in which background temperature information indicative a temperature of a background except for the detection object within the detection region; and an information update unit configured to update either one information out of the occupation information and the background temperature information based on the output of the temperature sensor and the other information out of the occupation information and the background temperature information.
