Google Research Team — has developed a prototype system that uses a home computer’s internal microphone to listen to the ambient audio in a room, determine what is being watched on TV and offer web-based supplemental information, services and shopping contextual to each program being watched. It’s strange, but it sounds like it works and people might really like it.

The system compresses the captured audio into irreversible (emphasis theirs) summary statistics which are then compared to a database of mass media statistics and used to determine what the browser should display. Possible service offerings discussed in the paper fall into four categories:

• Personalized information layers
• Ad hoc social peer communities
• Real-time popularity ratings
• TV- based bookmarks |
