Abstract
A method for joining a communication group by receiving and processing light and/or sound signals in a mobile device. The signaling may be light or audible signals, such as lights and/or music, that may be emitted in particular sequences. The mobile device may receive the light and/or sound signals with sensors, such as cameras and/or microphones, and may process the light and/or sound signals to obtain information encoded within the signals. The mobile device may decode detected signaling information and identify connectivity data that may be used to join and transmit messages to the communication group. In an embodiment, light and/or sound signals related to unknown third parties may be used by the mobile device to identify the third party based on queries to the communication group. In an embodiment, the mobile device may determine parameters for receiving and/or transmitting signals based on ambient conditions, such as ambient noise.
