Gesture-based object manipulation methods and devices

摘要

Gesture based control of objects displayed on touch screen displays is described. An object is displayed on a touch screen display, and a first touch operation is detected at a first position on the display. The first position is within an area that is associated with the displayed object. A second touch operation is detected within the area. After detecting the first and second touch operations another, a third touch operation is detected at a third position. A distance between the third position and the first position is calculated. When the distance is greater than a predetermined value, a copy of the object is displayed on the touch screen display.

主权项

1. A computer implemented method performed on a processing system that includes at least one processor, the processing system coupled to a memory, the processing system coupled to a touch screen display, the method comprising:
displaying a first object on the touch screen display; detecting a first touch input on the touch screen at a first position within an area that is associated with the first object; detecting a second touch input on the touch screen within the area at a second position that is different from the first position; detecting a third touch input on the touch screen at a third position after detecting the first and second touch inputs, the third position being different from the second position; determining a distance between the third position and the first position; and displaying a copy of the first object on the touch screen enabled display as a result of determining that the distance is greater than a predetermined value, wherein the second touch input and the third touch inputs are included in a continuous touch input connecting at least the second and third positions, wherein the detected first touch input is not included as part of the continuous touch input between at least the second and third positions.
