Abstract
An emulation system receives a swipe along a finger sensor to set a computer display in motion. After the swipe is completed, the display continues along its previous path. Depending on their direction, subsequent swipes can be used to accelerate or decelerate the motion. Gradually, the display decelerates. In one embodiment, this deceleration simulates an inertial decay, providing the user with a pleasing display that gradually rolls to a stop. The deceleration is modeled on a joystick return-to-home inertial decay, allowing the user greater control when navigating over the display. The finger sensor is used to emulate different electronic devices, such as a mouse, a scroll wheel, and a rotating wheel.
