Systems and methods for mitigating vigilance decrement while maintaining readiness using augmented reality in a vehicle
First Claim
1. A vigilance system for improving vigilance and readiness of an operator in an autonomous vehicle that includes an augmented reality (AR) display, comprising:
- one or more processors;
a memory communicably coupled to the one or more processors and storing;
a vigilance module including instructions that when executed by the one or more processors cause the one or more processors to compute an engagement level of the operator according to operator state information monitored from at least one internal sensor of the autonomous vehicle to characterize an extent of vigilance decrement and readiness presently exhibited by the operator relative to operating characteristics of the autonomous vehicle including an external environment around the autonomous vehicle and at least semi-autonomous operation of the autonomous vehicle; and
a rendering module including instructions that when executed by the one or more processors cause the one or more processors to dynamically render, on the AR display, at least one graphical element that is a visualization based, at least in part, on sensor data about the external environment from at least one external sensor of the autonomous vehicle,wherein the rendering module includes instructions to dynamically render the at least one graphical element by varying visual characteristics of the at least one graphical element as a function of the engagement level in order to improve the engagement level of the operator in regards to the readiness and the vigilance of the operator for i) a manual handover of control to the operator by the autonomous vehicle and ii) independent intervention by the operator to takeover control of the autonomous vehicle.

Abstract
System, methods, and other embodiments described herein relate to improving vigilance and readiness of an operator in a vehicle that includes an augmented reality (AR) display. In one embodiment, a method includes computing an engagement level of the operator to characterize an extent of vigilance decrement and readiness presently exhibited by the operator relative to operating characteristics of the vehicle including an external environment around the vehicle and at least semi-autonomous operation of the vehicle. The method includes dynamically rendering, on the AR display, graphical elements by varying visual characteristics of the at least one graphical element as a function of the engagement level and based, at least in part, on sensor data about the external environment. Dynamically rendering the at least one graphical element improves the at least semi-autonomous operation of the vehicle through inducing vigilance and readiness within the operator with respect to the operating characteristics.
