The present disclosure relates to an information processing device, an information processing method, and a program that enable simple and appropriate calibration. When a pen-type device incorporating an inertial measurement unit such as an IMU is moved and a drawn image corresponding to a track is displayed, calibration is implemented on the basis of a measurement value of the inertial measurement device in one stationary attitude and a latitude and an absolute azimuth of the inertial measurement device at that time when the pen-type device is inserted into a pen stand to be fixed in a predetermined direction. It is applicable to a device including an IMU.

Described herein are methods and systems for controlling a sensor assembly with a plurality of same type sensors. Sensors are operated in active and inactive states and have a corresponding performance parameter and reliability parameter that may be determined. The activation state of at least one of the sensors is changed based on an operational parameter. The performance parameter and/or the reliability parameter can then be updated.

A calculated current lapse rate is determined for a geographical area that includes a location of a mobile device. The calculated current lapse rate provides an estimated air temperature variation with respect to altitude variation for the location of the mobile device. An altitude of the mobile device is estimated. An uncertainty of the altitude of the mobile device is estimated based on a reference pressure and a reference temperature for a reference plane that is within the geographical area, a device pressure for the mobile device, and the calculated current lapse rate.
