LOW POWER NAVIGATION, DEVICES, SYSTEMS AND METHODS

摘要

A system and method are disclosed for conserving power during navigation, e.g., user device pointer/cursor navigation, using a fingerprint image sensor, that may comprise processing, via a computing device, fingerprint image sensor data indicative of finger position and movement with respect to a fingerprint image sensor surface in a finger navigation mode to determine if the finger is in a first finger navigation mode; processing, via the computing device, fingerprint image sensor data indicative of finger position and movement with respect to a fingerprint image sensor surface in a finger navigation mode to determine if the finger is in a second finger navigation mode; and transitioning, via the computing device, the fingerprint image sensor from a first power consumption mode to a second power consumption mode, based on detecting a transition from the first finger navigation mode to the second finger navigation mode.

1. A system, comprising:
a finger sensor, configured to detect finger motion on a sensor surface and to generate corresponding finger sensor data indicative of the finger motion; and a computing device, configured to:
determine whether the finger sensor data corresponds to a first finger navigation mode or a second finger navigation mode; andoperate the finger sensor in a first power consumption mode or a second power consumption mode based on determining that the finger sensor data corresponds to the first finger navigation mode or the second finger navigation mode, respectively.
