Scroll disc input apparatus for a data processing device
First Claim
1. An apparatus comprising:
- a data processing device having a memory for storing program code and data and a processor for processing the program code and data, and a display for displaying graphical images and text; and
a scroll disc rotatably and communicatively engaged with the data processing device, the control disc rotating on an axis which is substantially perpendicular to a plane defined by the display, the control disc communicatively engaged with the data processing device to cause a graphic element on the display to move in a first direction by a first predefined amount when rotated in a first direction and causing the graphic element to move in a second direction by the first predefined amount when rotated in a second direction.
