Manipulation of graphical objects

摘要

One or more graphical objects are displayed in a fixed orientation with reference to a sensed reference direction. Manipulation is achieved by fixing the orientation or position of a displayed graphical object with reference to an apparatus, such as the display itself or a proxy device, detecting a change in orientation of that apparatus and editing the orientation of the graphical object based on the detected change.

主权项

1. A method comprising:
displaying a first object on a display of a device at a first orientation, the first orientation set with respect to a reference direction, the display being fixed to the device such that rotation of the display requires an equal rotation of the device; displaying a second object on the display at a second orientation, the second orientation set with respect to the display; detecting a change in orientation of the display; and in response to detecting the change in orientation of the display:
continuing to display the first object at the first orientation, with respect to the reference direction, such that the first object appears to be stationary while the display rotates around the first object;determining an angle of rotation associated with the display; andwhen the angle of rotation exceeds a pre-defined threshold angle, rotating the second object by a specified increment to display the second object at a third orientation, the third orientation set with respect to the display.
