Abstract
A scanning apparatus and method for entering a user input into the apparatus uses a non-electrical control device having a target undersurface, which can be manually manipulated to a particular setting. The particular setting of the non-electrical control device is determined by processing an image of at least a portion of the target undersurface captured by a scan sensor of the scanning apparatus.
