Public Display Advertising Based on Bluetooth Device Presence

Public electronic displays can be used as an advertising medium when space is a scarce resource, and it is desirable to expose many advertisements to as wide an audience as possible. Although the efficiency of such advertising systems can be improved if the display is aware of the identity and interests of the audience, this knowledge is difficult to acquire when users are not actively interacting with the display. To this end, we present BluScreen, an intelligent public display, which selects and displays adverts in response to users detected in the audience. Here, users are identified and their advert viewing history tracked, by detecting any Bluetooth-enabled devices they are carrying, such as phones and PDAs.
