<p>An optical navigation device may have an adaptive sleep mode for preventing unwanted scrolling inputs. A motion indicator may move a device between a sleep mode and an active mode. According to the sleep mode, a number of different sleep states are defined which have further reduced frame rates. The device may be only woken from the deeper sleep modes once repeated motion events are detected. This may prevent the device from being woken accidentally, while preserving the user experience.</p> |
