Display device and method for controlling the same

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.

A display device comprising:

• a memory configured to store one or more instructions;
• and
• a processor configured to execute the one or more instructions stored in the memory,
• wherein the processor is configured to:
• continuously retrieve multipath channel characteristic data based on a wireless signal transmitted by a wireless router,
• perform preprocessing on the retrieved multipath channel characteristic data of the wireless signal,
• determine representative values for each reference time by calculating a similarity for each time period of result data corresponding to a result of the preprocessing,
• determine a motion within a specified region of a display device, based on a comparison result between the representative values and an adaptive threshold, and
• control a power mode of the display device based on the determined motion within the specified region of the display device.
