<P>PROBLEM TO BE SOLVED: To provide a user detection method etc. which can efficiently save power. <P>SOLUTION: An embodiment of the present invention provides a method of detecting user presence, comprising registering a client associated with the user on a host associated with the user and setting up wireless communication power. While setting up a wireless communication pairing, the client measures the host wireless communication power and uses it as a calibration threshold for distance detection. The client measures beacon power of the host radio and, when the beacon power is above the threshold, the client is regarded as proximate to the host. <P>COPYRIGHT: (C)2013,JPO&INPIT |
