Ear-worn electronic device incorporating gesture control system using frequency-hopping spread spectrum transmission

A method using a first ear-worn electronic device worn by a wearer and wirelessly coupled to at least a second electronic device, each of the electronic devices comprising a wireless transceiver operably coupled to an antenna, the method comprising:

• transmitting, from one or both of the first ear-worn electronic device and the second electronic device, signals at a plurality of different frequencies in accordance with a frequency hopping sequence;
• collecting, from one or both of the first ear-worn electronic device and the second electronic device, two-dimensional (2-D) RSSI (Received Signal Strength Indication) data comprising an RSSI value as a function of frequency and of time in response to transmission of the signals;
• detecting a particular input gesture of a plurality of input gestures of the wearer using the 2-D RSSI data;
• and
• implementing a predetermined function of at least one of the first ear-worn electronic device and the second electronic device in response to detecting the particular input gesture.

A system, comprising:

• a first body-worn electronic device configured to be worn by a wearer;
• a second electronic device;
• a wireless transceiver operably coupled to an antenna disposed in each of the electronic devices, wherein one or both of the first body-worn electronic device and the second electronic device are configured to:
• transmit signals at a plurality of different frequencies in accordance with a frequency hopping sequence;
• collect two-dimensional (2-D) RSSI (Received Signal Strength Indication) data comprising an RSSI value as a function of frequency and of time in response to transmission of the signals;
• detect a particular input gesture of a plurality of input gestures of the wearer using the 2-D RSSI data;
• and
• implement a predetermined function of at least one of the first body-worn electronic device and the second electronic device in response to detecting the particular input gesture.
