Device control system and method of determining altitude

摘要

A gaming system has a pressure measurement in the remote control (which may be the complete gaming apparatus) and this is used to derive a height of the remote control. In this way, barometric pressure measurement allows precise determination of the altitude of the game controller. The altitude information is then used to control the game.

1. A system comprising:
a base unit comprising a processor, the base unit hosting a software application; a remote control, wherein the remote control comprises
a hand-held controller configured to control the software application, anda pressure sensor configured to provide relative altitude information adapted to be used in the control of the software application; and a reference pressure sensor provided in the base unit or in a separate unit at a fixed height, wherein the processor is adapted to
determine calibration information depending on a relation between outputs of the pressure sensor of the remote control and the reference pressure sensor when a difference between an altitude of the pressure sensor of the remote control and an altitude of the reference pressure sensor is zero, anddetermine a relative height of the remote control with respect to the reference pressure sensor based on an output of the pressure sensor, on an output of the reference pressure sensor and on the calibration information.
