METHOD OF ASSESSING A PILOT EMOTIONAL STATE
A method 140 of assessing an operator emotional state 131 and sending an alert 144 based on the emotional state 131. The method 140 includes tracking 141 during a time period, using at least one sensor 103, 105, 106, 112, 117, one of an image sensor data, voice data or a biometric parameter of an operator. Determining 142, using a controller 120 that is operatively connected to at least one sensor 103, 105, 106, 112, 117, a probability of a likely emotional state 131 from a list of emotional states 131 of an operator based on one of the image sensor data, voice data or the biometric parameter. Comparing 143, using a processor, the probability of one of the likely emotional states 131 of the operator with a baseline emotional state 131 of the operator. Sending 144, using the controller 120, an alert if most likely emotional state deviates from the baseline emotional state by a predetermined threshold.

[0007] Every time a pilot enters a ****pit, data indicative of a pilot's emotional state can be collected. During a pre-flight routine, a pilot's voice, body movements, eye movements and various biometric parameters such as heart rate and blood pressure can be monitored and stored as data. Baseline statistics can be stored that are indicative of pilot's emotional or behavioral state. These statistics can used as a comparison for understanding a pilot's current emotional state. For example, if real-time data of a pilot is indicative of anger, i.e. loud voice, darting eye movements, high pulse rate, the system might alert a ground crew to the pilot's emotional state. In another example, if the real-time data shows a sudden spike or drop in pulse rate, this might be indicative of a pilot medical condition, to which the system might alert emergency medical personal. In these cases, it might be beneficial to remove the pilot from service of the aircraft.

[0008] It should be recognized that pilot stress levels and behaviors can be function of the pilot's personal habits such as food intake, exercise, and even sleep habits. Baseline models of pilot's ordinary or typical emotional state can be developed to provide a threshold indictor of the pilot baseline emotional state characteristics. The pilot's emotional state can vary over time or even flight-to-flight. For example, if a pilot did not get much rest before a flight, the pilot might become stressed or angry more easily. In other words, fatigue might increase stress or anger sensitivity to workload and minor changes in pilot environment can have a larger detrimental impact. As a result, it can be beneficial to track a pilot's emotional state during flight and adjust the pilot's workload when the pilot's emotional state exceeds a predetermined threshold.

Conclusions

[0083] The above described system and method provide for more robust eye(or other object) tracking under varying illumination conditions such as conditions of high brightness and reflection and in dark conditions. In particular, the eye tracking can be performed when there is strong contrast on the face, and when the subject is wearing dark or highly reflective glasses. The tight control of the LEDs also results in reducing cost, size and heat dissipation.

[0084] The invention leverages the fact that an LED has a nonlinear response and is more efficient at converting electrical energy into light at low drive currents. Using this property, the invention provides two dimensional control in terms of both the drive current amplitude and drive current pulse time to compensate for varying illumination conditions. In dark image conditions, higher output optical energies are achieved at the camera sensor by reducing the LED drive current amplitude and increasing the drive current pulse time over a longer camera exposure time. Conversely, in bright image conditions, higher instantaneous optical power can be achieved by increasing the LED drive current amplitude and reducing the drive current pulse time over a shorter camera exposure time.

[0085] The result is that higher image quality performance can be achieved with conventional LED components and thermal limitations over a wider range of lighting conditions.

SYSTEM AND METHOD FOR IMPROVING SIGNAL TO NOISE RATIO IN OBJECT TRACKING UNDER POOR LIGHT CONDITIONS
Described herein is a system and method for performing eye tracking. One embodiment provides a system (100) including a camera (106) for capturing images of a vehicle driver's (102) eye and light emitting diodes (LEDs - 108 and 110) configured to selectively illuminate the driver's eye during image capture by the camera (106). A processor (118) is configured to process at least a subset of the captured images to determine one or more eye tracking parameters of the subject's eye and to determine one or more illumination characteristics of the images. A controller (120) is configured to send an LED control signal to the LEDs (108 and 110) to control the drive current amplitude and pulse time of the LEDs (108 and 110). The controller (120) selectively adjusts the drive current amplitude and/or pulse time based on the determined illumination characteristics of a previous captured image or images.

As in the Toyota ABNORMALITY DETECTION DEVICE, ABNORMALITY DETECTION SYSTEM, AND ABNORMALITY DETECTION PROGRAM patent this PSA patent uses images' captured by a rear-view mirror camera'

METHOD FOR TRACKING THE DRIVING ACTIVITY OF A DRIVER OF A LAND MOTOR VEHICLE AND ASSOCIATED LAND MOTOR VEHICLE
The present invention relates to the field of systems for monitoring drivers of land motor vehicles. The invention relates in particular to a method for monitoring the driving activity of a driver of a land motor vehicle. The invention applies in particular to motor vehicles.
To improve the safety of motor vehicle drivers, on-board safety systems are known which help to reduce the chances that certain risk situations will occur. For example, to minimize the risk of collision, certain vehicles are equipped with anti-collision devices which activate automatic emergency braking when it is considered that too close proximity to the preceding vehicle exists. In another risk area, to avoid driving under the influence, some vehicles are fitted with safety systems including a breathalyser which is used to check the blood alcohol level during starting. Relative to certain particular risks, such systems therefore make it possible to improve the safety of road users. However, it is recognized that a significant risk factor in road safety is linked to the driving behavior of drivers.

According to another example, to minimize the risks relating to dangerous overtaking, the control unit 101 interacts with a detection means 102 arranged in the rear view mirror of the vehicle, eg a presence sensor, which is capable of generating a signal towards the control unit 101 when a vehicle is present in its detection field.

Thus, by allowing the monitoring of a multitude of parameters related to the driving behavior of a driver, the method according to the invention makes it possible to effectively minimize most of the risks that a driver can run or cause other road users to run. . Indeed, by interfacing a control unit which implements the method according to the invention with an autonomous or quasi-autonomous driving module of the vehicle, one can use the information provided by the control unit to automatically adapt, or to demand, a mode of conduct. According to a less invasive risk minimization system, it can also be envisaged that the information calculated by the control unit is presented to the driver via his smartphone when the latter is connected to the vehicle in place of the portable storage medium 106. In such a case, we will be able to take advantage of the other functionalities provided by the smartphone (screen and means of alert) to display a driving score, alert the user of faulty behavior and / or report the presence of signaling elements. road that should be taken into account.

Priority date refers to the earliest filing date in a family of patent applications. Where only a single patent application is involved, the priority date would obviously be the filing date of the sole application. If an applicant has filed a number of related patent applications, the priority date would be the filing date of the earliest patent filing that first disclosed the invention.

In operation, the system 20 for measuring the position of the eyes of the pilot measures a current position of the eyes of the pilot when the pilot is situated on his/her seat. This position of the eyes of the pilot corresponds, for example, to the position of the geometrical center of the two eyes of the pilot in a reference frame linked to the ****pit 3. The position of the eyes is a geometrical position which does not need to take the direction of the gaze of the pilot into account. The system 20 transmits the current position of the eyes of the pilot to the display computer 14 which receives it. The display computer 14 acquires, from the memory or from the database 16, information relating to the acceptable volume 30 for the position of the eyes of the pilot. The display computer 14 then compares the position of the eyes of the pilot with the acceptable volume 30. If the position of the eyes of the pilot is not included within the acceptable volume 30, the display computer 14 determines a direction in which the pilot would need to move his/her eyes in order to bring the position of the eyes back into the acceptable volume. In the example shown in FIG. 2, the acceptable volume 30 is situated on the right (seen from above) of the head of the pilot. Consequently, the pilot has to move his/her eyes to the right (by adjusting his/her seat in a suitable manner) in order to bring them into the acceptable volume 30. The display computer 14 then controls the display of an indication on the head-up display 18, this indication indicating the direction to the pilot in which he/she has to move his/her eyes. In particular, this indication may correspond to an arrow indicating the direction in which the pilot would need to move his/her eyes in order to bring their position into the acceptable volume 30. In the aforementioned example, this indication thus corresponds to an arrow 22a oriented to the right, as shown in FIG. 3A.

In one embodiment, the display computer 14 is configured for receiving information on the current flight phase of the aircraft (transmitted, for example, by an avionics system of the aircraft). The display computer 14 then verifies whether the current flight phase corresponds to a flight phase predetermined as a critical flight phase of the aircraft. The flight phases predetermined as critical flight phases of the aircraft correspond for example to the take-off or to the landing of the aircraft. When the current flight phase corresponds to a critical flight phase of the aircraft, the display computer 14 inhibits the display of the indication 22a, 22b to aid the positioning of the pilot. This avoids the pilot being distracted with the display of the indication, in order for him/her to be able to fully concentrate on flying the aircraft.

AIRCRAFT ****PIT AND METHOD OF DISPLAYING IN AN AIRCRAFT ****PIT
The ****pit of an aircraft comprises a head-up display, a display computer configured to control the display of information on the head-up display and a system for measuring the position of the eyes of a pilot of the aircraft. The display computer is configured to receive from the measuring system the position of the pilot's eyes, when the pilot is located in the ****pit, position information on the pilot's eyes, compare the received position of the pilot's eyes with an acceptable volume for the position of the pilot's eyes; and if the received position of the pilot's eyes is not included within the acceptable volume, determining a direction in which the pilot would need to move his/her eyes in order to bring the position of the eyes back into the acceptable volume, and controlling the display of an indication on the head-up display, indicating the direction to the pilot.

An aim of the present invention is notably to provide a solution to this need. It relates to a ****pit of an aircraft comprising:
a head-up display;
a display computer configured for controlling the display of information on the head-up display; and
a system for measuring the position of the eyes of a pilot of the aircraft.

The ****pit is noteworthy in that the display computer is configured for:
receiving from the system for measuring the position of the eyes of a pilot of the aircraft, when a pilot is located in the ****pit of the aircraft, position information on the eyes of the pilot;
comparing the received position of the eyes of the pilot with an acceptable volume for the position of the eyes of the pilot; and
if the received position of the eyes of the pilot is not included within the acceptable volume:
determining a direction in which the pilot would need to move his/her eyes in order to bring the position of the eyes back into the acceptable volume; and
controlling the display of an indication on the head-up display, indicating the direction to the pilot.
Thus, when the position of the eyes of the pilot is outside of the acceptable volume, the head-up display displays an indication indicating to the pilot a direction in which he/she must move his/her eyes. The pilot can thus modify the position of his/her seat so as to move his/her eyes in this direction so as to bring them into the acceptable volume. For as long as the position of the eyes of the pilot is not included within the acceptable volume, an indication of the direction in which the pilot has to move his/her eyes remains displayed on the head-up display. When the position of the eyes of the pilot is included within the acceptable volume, the indication is no longer displayed (or another indication is displayed, in order to inform the pilot that the position of his/her eyes is included within the acceptable volume) and the pilot thus knows that the position of his/her eyes is satisfactory.
