    • There is described a method for extending battery life in an optical pointing device powered by one or more battery cells (30), the optical pointing device including an optical motion sensing device (10) for tracking motion with respect to a surface (S) and comprising motion sensing circuitry (12) coupled to an optical sensor (15) and at least one light source (14) for illuminating a portion of the surface. The method comprises the steps of (i) monitoring the power output of the said one or more battery cells (30), (ii) detecting when the said power output falls below a certain threshold indicative of a low battery status (EOL) and (iii) upon detection of the low battery status, switching the optical pointing device into a low power consumption mode where power consumption of the optical pointing device is reduced and performance of the optical motion sensing device is partially degraded. There is also described an optical pointing device implementing this method.

    • There is described a method of providing indication of low battery status of a battery-powered pointing device designed for detecting motion and outputting motion reports representative of the detected motion, the method comprising the steps of detecting low battery status of the pointing device and affecting output of the motion reports, upon detection of the low battery status, by adding determined and/or pseudo­random components of motion to the motion reports. There is also described a method of providing indication of low battery status of a battery-powered pointing device designed for detecting motion and outputting motion reports representative of the detected motion, the pointing device controlling motion of a cursor element on a computer screen, this method comprising the steps of detecting low battery status of the pointing device and affecting motion of the cursor element on the computer screen, upon detection of the low battery status, by adding determined and/or pseudo-random components of motion to the motion of the cursor element. There is also described a method of providing indication of the low battery status consisting of affecting the graphical representation of the cursor element upon detection of the low battery status. Also described are a pointing device and software applications implementing these methods.
