Abstract
The invention provides an independent relative motion sensor for use in navigation operations using a fingerprint that do not require the power demanded by conventional devices. The independent relative motion sensor includes a linear array of sensing elements that captures a narrow string of data that is indicative of fingerprint features along a relatively narrow sample. This string of data is used to determine the velocity of travel for use in navigation operations. Using multiple sensors, motion and direction data can be computed and used to provide two-dimensional direction for navigating an object, such as a cursor on a monitor. The invention can be incorporated in an electronic device to provide improved navigation operations that demand less power.
