The
Interactive Window
Simple passive acoustic pickups turn a large sheet of
glass into an interactive surface, locating and characterizing
knocks and taps.
Innovation
Passive acoustic tracking of knocks and taps on glass
coupled with non-contact microwave sensing.
Vision
Although glass is a very common construction material,
it is generally passive, unless outfitted with a potentially
expensive and fragile touch-screen technology. Our technique
is a very simple retrofit, where four contact pickups
adhered to the inside surface of the glass are able to
track and characterize knocks on the outside surface.
Applications abound in areas ranging from retail (for
example, a new era of window browsing, where users can
explore content related to a store's merchandise or services
by appropriately knocking) to interactive museum cases
(for example, museum visitors could knock near a particular
object to hear its story).
