This paper describes an innovative solution to perform mouse functionality ("navigation") and image reconstruction ("scanning"). The application uses a recursive block-matching motion estimation algorithm and an optical or capacitive sensor. Results show this solution provides integrated mouse and scanner functionality at a very low cost.
