Billboard 'Whispers' At Passersby:
BlueBlastMedia's JP Freeley incorporated sound with the Audio Spotlight system along with regular billboard. Using the Audio Spotlight technology, sound can be focused to only a specific area, and provide audio just to that small region - all the way from a rooftop. The system projects sound down onto a focused area of the sidewalk and people who pass by the billboard are entertained by the sudden message, and their attention is directed to the billboard itself. The sound of a women's voice whispers, "Who's there? Who's There? ...It's not your imagination."
Billboard: Tailor Made Digital Display:
These are equipped with tiny cameras which gather the details about the passersby; their gender, approximate age and how long they looked at the billboard which are transmitted to a central database. Its said that the cameras use software to determine that a person is standing in front of a billboard, then analyze facial features to judge the person's gender and age. And the end result is to tailor a digital display to the person standing in front of it.
