Patent ID: 8378985

Claim:
An electronic device, comprising: a first touch panel disposed on a first side of the device and configured to receive a first touch input; a display disposed on the first side of the device; a touch interface configured to receive a second touch input, wherein the touch interface is disposed on a second side of the device that is different than the first side of the device; a control unit configured to: receive an indication of the first touch input from the first touch panel, receive an indication of the second touch input from the touch interface, determine alterations to a three dimensional view of a background displayed on the display in x, y and z directions, or x, y or z directions, based on the first touch input, navigate within the three dimensional view of the background displayed on the display by causing changes, based on the indication of the second touch input, in an azimuthal angle θ and a polar angle φ with a radius r being held constant, within a spherical coordinate system associated with the three dimensional view of the background displayed on the display, wherein the spherical coordinate system includes coordinates θ, φ, and r, and cause the display to display the three dimensional view of the background.
