Gesture Detection System and Method Using Radar Sensors

A device comprising:

• a screen;
• a plurality of millimeter-wave radars mounted on the device;
• and
• a controller configured to:
• at a first time, detect a first presence of an object in a field of view of a first millimeter-wave radar of the plurality of millimeter-wave radars;
• at a second time, detect a second presence of the object in a field of view of a second millimeter-wave radar of the plurality of millimeter-wave radars, the second time occurring after the first time;
• determine a gesture signature based on detecting the first presence of the object in the field of view of the first millimeter-wave radar at the first time and detecting the second presence of the object in the field of view of the second millimeter-wave radars at the second time;
• and
• execute a command based on the determined gesture signature.

A method comprising:

• detecting, at a first time, a first presence of a first object in a field of view of a first millimeter-wave radar of a plurality of millimeter-wave radars mounted on a device having a screen;
• detecting, at a second time, a second presence of a second object in a field of view of a second millimeter-wave radar of the plurality of millimeter-wave radars;
• determining a gesture signature based on outputs of the first and second millimeter-wave radars;
• and
• executing a command on the device based on the determined gesture signature.
