Pilot fatigue and attention tunneling using biometric monitoring
An on aircraft computer system records and analyzes biometric data to identify indicia of impaired performance, such as pilot fatigue, attention tunneling, or cognitive overload. Such impairment is identified by alterations in pilot gaze or eye movement, head movement, facial parameters, eye lid position, heart rate, breathing, or brain wave patterns. Appropriate corrective action is applied based on the type of impaired performance identified, including altering a level of automation, contacting a ground dispatcher or ground pilot, or contacting a co-pilot or other crew member. Biometric data is continuously logged and correlated with data from other avionics systems to refine formulas relating biometric data to states of alertness and crew rest procedures.

When indicia of impaired performance are identified, a corrective action may be initiated 306. In at least one embodiment, the corrective action is specific to the type of impaired performance identified. For example, in a highly automated environment, where pilot fatigue is identified, the level of aircraft automation may be altered; reduced to provide the pilot additional stimulus or increased to lower the cognitive workload. Alternatively, or in addition, a ground dispatcher or ground pilot may be automatically contacted to interact with the pilot to provide additional stimulus and evaluate the pilot's condition, or take over specific flight tasks from the ground to assist the pilot in the aircraft. Further, where additional rested crew members are available, a crew member, such as a co-pilot, may be automatically contacted to take over certain tasks from the pilot and alter the crew resource management (CRM).

In a situation where attention tunneling is identified, specific instrument cues may be utilized to redirect the pilot's attention. In at least one embodiment, such cues may be organized according to an idealized instrument observation pattern to facilitate the periodic observation of critical instruments. Attention capture techniques such as colors, symbology, blinking or flashing indicators, motion, haptic feedback, or sound may be used to disengage attention tunneling habits and shift the pilot's gaze toward information critical to the operational scenario. Where applicable, eye tracking may be used to determine exactly where the pilot's gaze is focused, and display warning messages at the identified location.

EYE TRACKING FOR HEAD-WORN DISPLAY
A display assembly (105) for mounting on a head-worn device such as a helmet, and having a partially reflective surface located in a field of view of a user, a display projector (40, 50, 200) for projecting light towards the user via the partially reflective surface, a sensor (60, 210) for use in tracking an eye of the user, and a partially reflective imaging surface (120, 220, 225) located in the field of view. The sensor is aligned to receive light forming an image of an eye reflected by the partially reflective imaging surface, the image being for use in the eye-tracking. By using a reflected image, the camera location can be arranged to improve the potentially conflicting needs of keeping the field of view clear, and of having an image from directly in front of the eye, and of limiting the weight and size and imbalance of the helmet. The visor may be used as the partially reflective surface. IR Illumination may be provided by the display projector.

This FIG. 7 thus shows an example of a display assembly comprising an eye tracking analyser coupled to the sensor and configured to output an eye tracking indication, and the display assembly comprising an output display generator, coupled to the eye tracking analyser and configured to generate the display according to the eye tracking indication. By generating the display according to the eye tracking, a possible advantage is that the display can be optimised, for example to put more information where the user is looking, or declutter the area where the user is looking, or alter the emphasis of information or the size of text in different parts for example, according to where the user is looking. The eye tracking indication can encompass information on position or movement of the eye, focal distance, stress levels, tiredness levels and so on. Some of these functions of the display assembly may be carried out off the helmet, to minimise weight, but in applications where that is not a limiting constraint there may be advantages in including them in the parts mounted on the helmet. Therefore, references to the display assembly being for mounting on the helmet are intended to encompass display assemblies having some parts such as processors for these functions not being mounted on the helmet.

SYSTEMS AND METHODS FOR SIMULATING INSTANTANEOUS ATTENTIVE HUMAN RESPONSES TO ROAD HAZARDS FOR IMPROVED EARLY WARNING SYSTEMS AND FLEET DATA HARVESTING
A system for predicting a hazardous event from road-scene data includes an electronic control unit configured to implement a neural network and a camera communicatively coupled to the electronic control unit, wherein the camera generates the road-scene data. The electronic control unit is configured to receive the road-scene data from the camera, and predict, with the neural network, an occurrence of the hazardous event within the road-scene data from the camera.

When a trained neural network is implemented, for example, in a vehicle having one or more sensors that generates input data to the neural network, the neural network may enable systems to provide assistance to a driver or even enable autonomous control to maneuver a road-scene in which a hazardous event is predicted. The trained neural network can detect near-miss, risky road-use and other heavily-tailed events. The output of the trained neural network may be used in a real-time feedback loop for providing warning systems to the driver depending on the severity of the estimated hazard signal and its location relative to where the driver is actually looking in the scene, for example, when information about the driver's gaze is obtainable through a driver monitoring system. Furthermore, through the generation of a risk-weighted saliency map a vehicle controller may direct computational resources and/or sensors to focus on risk-weighted salient portions of the road-scene. For example, a directable LIDAR system or high-resolution imaging device may be focused to capture data with respect to the risk-weighted salient portions of the road-scene.

The system 100 may include a gaze-tracking system 138 for tracking an eye or gaze direction of a subject to generate a gaze direction vector for determining where a viewer is looking when viewing road-scene video data on a display device (as described in more detail with respect to FIG. 3A) or within a road-scene in the environment of a vehicle (as described in more detail with respect to FIG. 3B). The gaze-tracking system 138 may include one or more cameras 140 and/or an array of infrared light detectors positioned to view one or more eyes of a subject. The gaze-tracking system 138 may also include or be communicatively coupled to an illuminating device 139 which may be an infrared or near-infrared light emitter. The illuminating device 139 may emit infrared or near-infrared light, which may be reflected off a portion of the eye creating a profile that is more readily detectable than visible light reflections off an eye for eye-tracking purposes.

ROUTE GUIDANCE APPARATUS AND METHOD
A route guidance apparatus and method are provided. The route guidance apparatus includes an image acquisition unit that collects image data of an area in front of a vehicle using a camera and a driver view recognition unit that calculates the range of a driver viewing angle by detecting a driver eye height driver a driver's gaze direction. An image processing unit extracts a region of interest corresponding to the range of the driver viewing angle from the image data and generates a route guidance image by overlaying a direction indicator corresponding to a driving route on the region of interest. A display unit outputs the route guidance image.

[0039] The driver's view recognition unit 220 may be configured to calculate preprocessing information to extract some regions that correspond to a driver's gaze direction from the image data photographed by the camera 100. Particularly, if the whole region of the image data is output to the display unit 260, a driver's recognition rate of the guide point may be lowered due to a difference between the range of an angle of view of an image collected by the camera 100 and the range a viewing angle recognized by driver's eyes. Therefore, the driver's view recognition unit 220 may be configured to calculate the preprocessing information to convert a view point of the collected image data into, for example, a driver's view point not a camera's view point.

[0040] Additionally, the driver's view recognition unit 220 may be configured to calculate the range of the viewing angle by detecting an eye height H and a gaze direction D of the driver in the vehicle, and transmit coordinate information of the calculated range of the viewing point to the image processing unit 250. Particularly, the driver's view recognition unit 220 may be configured to detect the driver's eye height H based on an installation position of the camera 100, estimate the gaze direction D using a face direction and a central position of the eyes of the corresponding driver, and calculate the range of the driver's viewing angle based on the detected driver's eye height H and the estimated gaze direction D.

Among them, the attention detection method includes: obtaining coordinate data matching the driver's line of sight direction according to a set period, and forming a coordinate sequence according to the time sequence of each coordinate data; according to the currently obtained target coordinate data, and the coordinate sequence The set number of coordinate data adjacent to the target coordinate data is used to calculate the distance of the driver’s gaze change trajectory and the radius of the gaze change range; according to the historical coordinate sequence formed by the driver in multiple historical driving processes, the gaze change trajectory distance and the line of sight are calculated The occurrence probability of the radius of change in the normal driving process; according to the occurrence probability, the driver's attention state is determined. The technical solution of the embodiment of the present invention can recognize whether the driver is in a state of distracted attention by acquiring the driver's line of sight activity state, thereby improving driving safety.

The coordinate data acquisition module is used to acquire coordinate data matching the driver's line of sight direction according to a set period, and form a coordinate sequence according to the time sequence of each coordinate data;

Exemplarily, the DMS first recognizes the driver’s face to determine the driver’s identity, and then obtains the coordinate data of the driver’s line of sight through the camera every 1 second, and sends it to the control terminal. The control terminal pair receives The coordinate data of the current driver is cached, and then after the set time is reached, for example, 10000 seconds, all the received coordinate data is stored in the archive database corresponding to the current driver’s identity to construct the stored coordinate data for the current driver database.

[0030] In the case at hand, a device may be understood as an electrical device that processes sensor signals and outputs control and/or data signals as a function of them. The device may have an interface, which may be implemented as hardware and/or software. In a hardware configuration, the interfaces may, for example, be part of a so-called system ASIC that includes many different functions of the device. However, it is also possible for the interfaces to be separate, integrated circuits or to be at least partially made up of discrete components. In a software configuration, the interfaces may be software modules that are present, for example, on a microcontroller in addition to other software modules.
