Claim 11:
12. A method of controlling a display device, the method comprising:
retrieving multipath channel characteristic data based on a wireless signal transmitted by a wireless router;
performing preprocessing on the retrieved multipath channel characteristic data of the wireless signal;
determining representative values for each reference time by calculating a similarity for each time period of result data corresponding to a result of the preprocessing;
determining a motion within a specified region of the display device, based on a change in the representative values over time; and
controlling the display device based on the determined motion within the specified region of the display device,
wherein a number of subcarriers of the result data is less than a number of subcarriers of the multipath channel characteristic data before the preprocessing.
