Method, system, signal and software for sensing remote battery life based upon cursor characteristics

摘要

The present invention describes a method, signal, system, and software for use in a system including a host device and at least one battery powered cursor control device. The status of the battery in the device is estimated by evaluating the periods of inactivity in the cursor and/or the cursor control device and by evaluating the movement of the cursor and/or the cursor control device across a display to determine unusual behavior. Upon unusual behavior determination, the battery's status is then communicated to the user via the host device. The entire method can be implemented without consuming any device battery power except the power consumed during normal device operation.
