Abstract:
The appeal of direct manipulation with multi-touch interfaces stems from the experience it offers. As the user slides their fingers along a touch surface, objects react by rotating, translating, and scaling themselves so that the same point on an object always remains underneath the same fingertip. Since objects move in a predictable and realistic fashion, users are given the impression of “gripping” real objects. Direct manipulation essentially provides an intuitive and controllable mapping between points in local space and points in screen space, without the need for any explicit gesture processing.
