In some embodiments, an electronic device performs an action in response to detection of a sequence of one or more motion gestures. Motion gesture information of a first electronic device optionally includes a first portion representing a respective attitude of the first electronic device relative to a frame of reference and a second portion that includes movement of the first electronic device from the respective attitude of the first electronic device. In accordance with a determination that the movement of the first electronic device during the second portion of the motion gesture meets movement criteria for a movement gesture that corresponds to the respective attitude of the first electronic device, a process is initiated to control the first electronic device or a second electronic device in accordance with the second portion of the motion gesture.

System and method of controlling devices using motion gestures

An electronic device may include control circuitry, sensors, and wireless circuitry having antennas. The sensors may generate sensor data that is used by the control circuitry to identify an operating environment for the device. The sensor data may include a grip map generated by a touch-sensitive display, infrared facial recognition image signals or other image signals, an angle of arrival of sound received by a set of microphones, impedance data from an impedance sensor, and any other desired sensor data. The control circuitry may use the sensor data, radio-frequency spatial ranging data, information about whether audio is being played over an ear speaker, and/or information about communications protocols in use to identify the operating environment. The control circuitry may adjust antenna settings for the wireless circuitry based on the identified operating environment to ensure that the antennas operate with satisfactory antenna efficiency regardless of operating conditions.

Electronic device having adjustable antenna settings

An electronic device may include an antenna having a resonating element, an antenna ground, and a feed. First and second tunable components may be coupled to the resonating element. Adjustable matching circuitry may be coupled to the feed. Control circuitry may use the first tunable component to tune a midband antenna resonance when sensor circuitry identifies that the device is being held in a right hand and may use the second tunable component to tune the midband resonance when the sensor circuitry identifies that the device is being held in a left hand. For tuning a low band resonance, the control circuitry may place the antenna in different tuning states by sequentially adjusting a selected one of the matching circuitry and the tunable components, potentially reverting to a previous tuning state at each step in the sequence. This may ensure that antenna efficiency is satisfactory regardless of antenna loading conditions.
