Natural and implicit interaction systems

Abstract

Humans constantly seek information about their environment. In doing so, they position their bodies and orient their sensory organs to obtain the best possible data. We see this behavior everyday for example, shoppers browsing items on shelves in a retail store will bend down and lean forward to more closely examine items that caught their eye. The notion that humans move purposefully to obtain information provides a guiding framework to interpret natural body movements and gestures as implicit cues. With the ability to infer what data a person is seeking, we can design novel interaction systems that provide that data without the need for an explicit input interface.
