Abstract
The advent of touch-sensitive and camera-based digital
surfaces has spawned considerable development in two
types of hand-based interaction techniques. In particular,
people can interact: 1) directly on the surface via direct
touch, or 2) above the surface via hand motions. While
both types have value on their own, we believe much more
potent interactions are achievable by unifying interaction
techniques across this space. That is, the underlying system
should treat this space as a continuum, where a person can
naturally move from gestures over the surface to touches
directly on it and back again. We illustrate by example,
where we unify actions such as selecting, grabbing, moving,
reaching, and lifting across this continuum of space.
