Patent ID: 8678903

Claim:
A mobile device having a virtual spin wheel, comprising: a body having a display mounted thereon; a rotation sensor mounted in the body; and a processing module mounted in the body, electrically connected to the display and the rotation sensor, having a virtual spin wheel control procedure, and storing a spin wheel image and a pointer image, wherein the virtual spin wheel control procedure reads the spin wheel image and the pointer image and displays the spin wheel image and the pointer image on the display, divides the spin wheel image into multiple angular target zones with each target zone defined to correspond to a selection result, sets up an initial alignment direction on the spin wheel image for the pointer image to point to the initial alignment direction, receives rotation data outputted from the rotation sensor and calculates a rotation angle of the mobile device according to the rotation data, adds the rotation angle to the initial alignment direction to determine a final alignment direction, determines one of the target zones on the spin wheel image of the mobile device to which the final alignment direction points, points the pointer image to the final alignment direction on the corresponding target zone, and executes an operation corresponding to the selection result designated to the target zone.
