Wearable device and system for monitoring physical behavior of a vehicle operator
First Claim
1. A system for monitoring behavior of an operator of a vehicle, comprising:
- a wearable electronic device configured to be worn on the head of an operator of the vehicle, wherein the wearable electronic device comprises a motion sensor;
a processor; and
a non-transitory computer-readable medium containing programming instructions that, when executed by the computer, cause the processor to;
receive a first set of data from the motion sensor,analyze the first set of data to detect a pattern of motion that comprises a head rotational motion of the operator of the vehicle by;
determining a forward-facing direction position as a position corresponding to the most common orientation of the wearable device,determining, based on the first set of data from the motion sensor, angular displacement of the operator'"'"'s head, anddetermining whether the angular displacement corresponds to a phone usage event, wherein the phone usage event remained constant for at least a threshold period of time,access a data set corresponding to a plurality of patterns of motion,use the data set corresponding to the plurality of patterns of motion to analyze the detected pattern of motion and determine a physical behavior of the operator of the vehicle based on the detected pattern of motion by determining that the operator exhibited dangerous operator behavior if the system detected a phone usage event for at least a threshold period of time, andgenerate an alert if the determined physical behavior corresponds to a dangerous operator behavior.

Abstract
A system uses a wearable electronic device to monitoring behavior of an operator of a vehicle. The wearable device is worn on the head of the operator of the vehicle and includes one or more motion sensors. A processor of the wearable device or of a proximate portable electronic device receives data from the one or more motion sensors and detects a pattern of motion based on the data. The system then may determine a physiological state or physical behavior of the driver based on the detected patterns or motion. Detected physiological states may include head bobs associated with sleepiness. Detected physical behaviors may include dangerous behaviors such as phone usage, prolonged gazes, sudden lane changes, or hard braking or steering.
