The Responsive Window turns taps on glass into an information interface. Sensors capture all the characteristics of the window knock - location, intensity of hit, and type of hit (e.g., bare hand or hard object). Interactive graphics dynamically respond to all of these parameters and are projected onto a holographic screen placed behind the glass. This glass wall is again a boundary, this time between the real and the synthetic, across which we are invited to knock.
