Methods and devices provide an efficient user interface for initiating a function by detecting an ellipsoidal continuous touch path on a touch surface of a computing device. In an embodiment the initiated function may end an application. A user may initiate the function operation by tracing an ellipsoidal shape (e.g., a circle) a touchscreen or touchpad. A display image may be contorted to inform the user about the progress towards accomplishing the function. The function operation of contorting the display image may begin at a minimum measure of the traced path and complete at a maximum measure of the traced path. In an embodiment, terminating an application and returning to the home display may be achieved in response to a clockwise path trace and minimizing of an application and returning to home display may be achieved in response to a counterclockwise path trace, or vice versa.
