A system for controlling an autonomous vehicle is capable of predicting and eliminating a possibility of motion sickness before and during travelling of the autonomous vehicle. The system includes: a first control unit which compares a first vehicle motion sickness index that is determined by a travelling simulation with a first threshold set including passenger information before travelling and controls a boarding location of a passenger before travelling; and a second control unit which computes a passenger motion sickness index from passenger state information and vehicle state information detected during travelling, compares a second threshold indicating the degree of sensitivity to motion sickness according to passenger information during travelling with the passenger motion sickness index, and controls the autonomous vehicle so as to reduce or eliminate a generation of a motion sickness causing frequency.

MOTION SICKNESS DETECTION SYSTEM FOR AUTONOMOUS VEHICLES
Techniques described herein include detecting a degree of motion sickness experienced by a user within a vehicle. A suitable combination of physiological data (heart rate, heart rate variability parameters, blood volume pulse, oxygen values, respiration values, galvanic skin response, skin conductance values, and the like), eye gaze data (e.g., images of the user), vehicle motion data (e.g., accelerometer, gyroscope data indicative of vehicle oscillations) may be utilized to identify the degree of motion sickness experienced by the user. One or more autonomous actions may be performed to prevent an escalation in the degree of motion sickness experienced by the user or to ameliorate the degree of motion sickness currently experienced by the user.

DRIVER MONITORING SYSTEM
[0023] The image capturing device 10 includes a camera and a projector. The camera is configured by a lens and an image capturing element and is for example a CMOS (complementary metal oxide semiconductor) camera or a CCD (charge coupled device) camera. The projector is comprised of LEDs (light emitting diodes). For example, it is comprised of two near infrared LEDs placed at the both sides of the camera. By irradiating the driver with near infrared light, it is possible to capture the face of the driver without irritating the driver even at night time or otherwise when the luminance is low. Further, a band pass filter removing light of wavelength components other than near infrared light is provided inside the camera, while a visible light cut filter removing light of the red wavelength component emitted from the near infrared LEDs is provided in front of the projector.

DRIVER ATTENTION STATE ESTIMATION
[0050] Referring still to FIG. 2, system 100 also includes a pair of infrared light sources in the form of light emitting diodes (LEDs) 108 and 110, horizontally symmetrically disposed at respective positions proximate to camera 106 on vehicle dash 107. LEDs 108 and 110 are configured to illuminate driver 102 with infrared radiation during a time when camera 106 is capturing an image, so as to enhance the driver's face to obtain high quality images of the driver's face or facial features. Operation of camera 106 and LEDs 108 and 110 in the infrared range reduces visual distraction to the driver. LEDs 108, 110 may be operated continuously, intermittently or periodically and may be operated alternatively in a strobed fashion which provides operational advantages in reducing glare present in the images. Operation of camera 106 and LEDs 108, 110 is controlled by an associated controller 112 which includes a computer processor or microprocessor and memory for storing and buffering the captured images from camera 201. In other embodiments, different types of light sources may be used in place of LEDs.

MONITORING AND SCORING PASSENGER ATTENTION
Disclosed herein is a passenger monitoring system for monitoring an observed attribute of a passenger in a vehicle. The observed attribute may include a gaze of the passenger, a head track of the passenger, and other observations about the passenger in the vehicle. Based on the observed attribute(s), a field of view of the passenger may be determined. Based on the field of view, a focus point of the passenger may be determined, where the focus point is estimated to be within the field of view. If a sign (e.g., a road sign, a billboard, etc.) is within the field of view of the passenger, record an attention score for the sign based on a duration of time during which the sign is within the field of view and estimated to be the focus point of the passenger.

23 -Today's vehicles, and in particular autonomous or partially autonomous vehicles, are equipped with monitoring systems that are typically related to safety systems for warning a driver or assisting a driver in reacting to objects that may appear in the vehicle's vicinity. The monitoring systems typically include a variety of inputs, sensors, cameras, and other information-gathering devices to assist the driver and/or the vehicle in making decisions based on those inputs for safely operating the vehicle in a variety of situations as the environment around the vehicle changes. While such monitoring systems have been used to asses the operation of the vehicle or whether a driver has changed or failed to change the operation of the vehicle in response to a detected event, current solutions do not assess the attention of the passenger to an object outside the vehicle. As discussed in more detail below, the instant disclosure provides a system for monitoring and assessing the attention of the passenger to an external object (e.g., a road sign) that may be within the field of view of the passenger in a vehicle. The system may calculate the duration of the passenger's attention and combine it with other data to generate a score for object's ability to maintain the attention of the passenger, which may be useful for rating a sign's effectiveness in, for example, communicating road information to the passenger or communicating an advertisement to the passenger.

VISUAL BEHAVIOR GUIDED OBJECT DETECTION
[0021] According to at least one additional illustrative example, a system is described that comprises: an eye-tracking system including a sensor; a computer communicatively coupled to the sensor and the eye-tracking system, the computer comprising one or more processors and memory storing instructions executable by the one or more processors, wherein the instructions, when executed by the processor, cause the processor to: receive, from the eye-tracking system, an image frame captured while an operator is controlling a vehicle; receive, from the eye-tracking system, eyeball gaze data corresponding to the image frame; and iteratively train a deep neural network to determine an object of interest depicted within the image frame based on the eyeball gaze data. The deep neural network generates at least one feature map and determine a proposed region corresponding to the object of interest within the at least one feature map based on the eyeball gaze data.

[0040] As shown in FIGS. 1 and 2, eye-tracking system 14 may comprise any device or apparatus that monitors eyeball gaze data of the operator and repeatedly determines a gaze point (e.g., where the operator is looking) that corresponds with a captured image. In some examples, the eye-tracking system 14 comprises a forward-looking sensor 22 (e.g., such as a red-green-blue (RGB) camera) that concurrently captures video representative of the operator's field of view (FOV), multiple eye-monitoring cameras 24, multiple illuminators 26 directed toward the operator's eyes, and a computer 28 configured to determine repeatedly eyeball gaze data of the operator for a plurality of image frames of video data from the sensor 22. The eye-tracking system 14 may be a so-called wearable eye-tracking system or it may be a system mounted in the vehicle 12. A non-limiting commercial implementation of the eye-tracking system 14 is the “Pro Glasses 2” by Tobii AB which comprise an eyeglasses frame, lenses, and the hardware discussed above. In other examples, the sensor 22 and/or computer 28 may not be part of a common assembly with the camera(s) 24 and illuminator(s) 26—e.g., the sensor 22 could be mounted elsewhere in the vehicle 12 or the like.
