Abstract
Detecting local interactive wireless devices and an indication of services provided by or associated with them. A user's wireless device sends a ping signal based upon user input, a command from a server, or a command from another wireless device. The ping signal is used for short range wireless communication with other wireless devices. The other wireless devices within range receive the ping signal and transmit back a response. The user's wireless device assembles the responses into a structured format and can use them to display an identification of the wireless devices within the range or other information such as an indication of services of the wireless devices or services of entities associated with them. It can also transmit the responses to the server in order to obtain additional information about services within the range.
