Abstract
A computer accessory device configured to communicate with a computer includes a two-dimensional sensor array configured to generate image data as the device is moved over a surface. A first memory is configured to store a first set of images based on a first set of the image data. A second memory is configured to store a second set of images based on a second set of the image data. The second set of images is configured to be stitched-together into a stitched-together image. At least one controller is configured to generate navigation information based on the first set of images. The navigation information is indicative of displacement and rotation of the device.
