Adaptive navigation and location-based services based on user behavior patterns
First Claim
1. A system for providing adaptive guidance for driver navigation of a vehicle, said system comprising:
- a plurality of sensor systems for monitoring and analyzing behavior of a driver;
a display device for displaying navigation maps and providing visual navigation instructions to the driver;
a speaker for providing audio navigation instructions to the driver; and
an adaptive navigation guidance processor which receives output signals from the sensor systems and is configured with algorithms including;
a situation detector module configured to determine a level of driver satisfaction with navigation guidance content and timing;
an error and behavior recorder module configured to identify driver errors and behaviors;
a causal analyzer module configured to determine correlations between the driver errors and behaviors and the level of driver satisfaction with navigation guidance content and timing; and
an adaptive navigation guidance module configured to adaptively modify the navigation guidance content and timing based on outputs from the situation detector module, the error and behavior recorder module and the causal analyzer module, and provide the navigation guidance to the driver via an audio speaker or display navigation map and provide visual navigation instructions the display device, including providing ad hoc guidance instructions to the driver when behavior patterns indicate that the driver is uncertain about a current driving route.

Abstract
A method and system are disclosed for adaptive driver guidance for navigation and location-based services based on user behavior patterns. A driver-facing camera and a gaze tracking system determine the location of the driver'"'"'s visual focus while an outside-facing camera detects and interprets external driving situations, a microphone and a speech analyzer identify driver vocalizations, and driver-proximate sensors and the driver-facing camera detect driver emotions. The driver'"'"'s visual focus, the driver vocalizations and the driver emotions, along with vehicle system parameters from a data bus, are used to evaluate driver satisfaction with navigation guidance and determine driver behavior patterns. An adaptive navigation guidance engine modifies navigation guidance content and timing based on the driver satisfaction and behavior patterns. Adaptation of guidance for location-based services is also provided.
