RE: COGNITIVE LOAD PREDICTOR AND DECISION AID - 2023-04-2729 Apr 2023 09:39
As previously alluded to, cognitive state detection and decision aid system 200 can be implemented as and/or include one or more components of one or more devices described herein. With respect to vehicles, circuit 210 can be implemented as an electronic control unit (ECU) or as part of an ECU of a vehicle. In other embodiments, cognitive state detection and response circuit 210 can be implemented independently of the ECU, for example, as another system 258 of the vehicle. Further, with respect to vehicle based devices, sensors 220, system elements 258, and cognitive state detection and response circuit 210 can be part of or include an automated vehicle system/advanced driver assistance system (ADAS). ADAS can provide navigation control signals (e.g. control signals to actuate the vehicle and/or operate one or more systems 258) for the vehicle to navigate a variety of situations. As used herein, ADAS can be an autonomous vehicle control system adapted for any level of vehicle control and/or driving autonomy. For example, the ADAS can be adapted for level 1, level 2, level 3, level 4, and/or level 5 autonomy (according to SAE standard). ADAS can allow for control mode blending (i.e. blending of autonomous and/or assisted control modes with human driver control). ADAS can correspond to a real-time machine perception system for vehicle actuation in a multi-vehicle environment. Continuing the example of a vehicle, controls systems 223 can include controls systems for an ADAS, such as steering controls, throttle/brake controls, transmission control, propulsion control, vehicle hardware interface controls, actuator controls, sensor fusion systems, risk assessment systems, computer vision systems, obstacle avoidance systems, path and planning systems as known in the vehicle arts.
In some embodiments, the cognitive state of the user can include that the user is in a non-agitated cognitive state (for example, only mildly upset, not angry, calm). For example, the user's heart rate may be calm, the user may be using happy, hopeful lexicography, their eye gaze does not wander, and contextually (e.g. via contextual and/or environmental sensors), the user is detected to be in a comfortable, and well-lit work environment, etc.) In some embodiments, the user may be detected to be in an agitated cognitive state (the user is angry, hot and sweaty, in an uncomfortable body position, with eyes darting, and a βscowlingβ facial expression, and speaking in angry tones). The cognitive state can include that the user is stressed, tired, alter, distracted, intoxicated, medicated, angry, and/or calm.
