Spilling: Expanding Hand held Interaction to Touch Table Displays

We envision a nomadic model of interaction where the personal computer fits in your pocket. Such a computer is extremely limited in screen space. A technique is described for “spilling” the display of a hand held computer onto a much larger table top display surface. Because our model of nomadic computing frequently involves the use of untrusted display services we restrict interactive input to the hand held. Navigation techniques such as scrolling or turning the display can be expressed through the table top. The orientation and position of the hand held on the table top is detected using three conductive feet that appear to the touch table like three finger touches. An algorithm is given for detecting the three touch positions from the table’s sensing mechanism.
