Methods and systems for selecting and controlling smart devices
Systems and methods are provided for identifying devices via a directional signal. A first directional signal having a first solid angle is emitted from a first device during a first time period, and a second directional signal having a second solid angle is emitted from the first device during a second time period. A second device that has received the first signal emitted during the first time period and has received the second signal emitted during the second time period is identified. A third device that has not received the first signal emitted during the first time period and has received the second signal emitted during the second time period is identified. A user interface element based on the identifying the second device and the identifying the third device is generated, for output at the first device.
