Abstract
The present invention relates to a system and method for managing energy consumption in a multi-sensor user-carried device during indoor navigation. In an embodiment of the invention, the device calculates a motion mode, a location mode, or an operational mode, each of which is used to modify sensor behavior, e.g., sampling rate, and/or CPU load, e.g., filtering and modeling complexity. The motion mode describes the manner in which the user is moving (standing still, walking, passive transport for example), the location mode describes a feature of the user's location (near level change or intersection for example), and the operational mode describes the manner in which the user is interacting with the device (holding and monitoring, holding and not monitoring, not holding for example).
