Definitions

  • the present invention relates to the field of automotive safety design and accessories.
  • the present invention relates to the field of drowsy driver detection.
  • Driver Drowsiness Detection is a car safety technology which prevents accidents when the driver is getting drowsy.
  • Various studies have suggested that around 20% of all road accidents are fatigue-related, up to 50% on certain roads.
  • Mercedes-Benz unveiled a system which monitors the driver's fatigue level and drowsiness based on his/her driving inputs. It issues a visual and audible alarm to alert the driver if he or she is too drowsy to continue driving safely.
  • the present invention is directed to eyeglasses (10) for a driver (24), the eyeglasses (10) comprising:
  • At least one digital camera (12) fixed to the eyeglasses (10), the at least one digital camera (12) for being directed to view at least one eye (22) of the driver, and to produce successive images or video of the at least one eye (22);

  • goggles refers to forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, and in swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems.
  • Sun glasses are a form of goggles designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened.
  • Fig. 1 depicts goggles according to one embodiment of the present invention.
  • Goggles 10 according to the present invention constitute eyeglasses for being worn by a driver 24 driving a vehicle 26.
  • the term "goggles" is suitable, since except for protecting the eyewear, such as against the sun, goggles 10 of the present invention are intended for protecting the driver 24 from traffic accidents.
  • Fig. 2 depicts the goggles of Fig. 1 alone.
  • Goggles 10 preferably seem similar to common sun glasses or eye glasses.
  • the frame 36 includes rims 38, a bar 32 connecting rims 38, and temple arms 40 extending from rims 38.
  • the lenses 34 held by rims 38 may constitute lenses, and may be colored, polarized or darkened.
  • Fig. 3 depicts elements of the goggles of Fig. 1.
  • the frame 36 of goggles 10, typically rims 38 thereof, includes digital cameras 12, one for each eye and additional accessories described below.
  • Fig. 4 depicts the camera of Fig. 3 and the function thereof.
  • Camera 12 produces successive images and/or video of the eye 22.
  • the captures are of the pupil of eye 22. This observation is intended for avoiding an event of a drowsy or sleepy driver.
  • Camera 12 Since driver 24 wears goggles 10, camera 12 is stationary in relation to eye 22. Thus, camera 12 may always be directed onto the pupil of eye 22, and thus may diligently watch the pupil, and indicate the changes thereon.
  • Camera 12 accompanied by an image processor may estimate a drowsy state of the driver according to ⁇ the shape of the pupil, the blink duration, the blink frequency, the percentage of the eye closure, the driver's gaze, the facial expressions, the amplitude of the opening of the eye to velocity ratio of the opening.
  • goggles 10 further include means for wakening the driver. These wakening means are efficient and suited to this purpose, since goggles 10 are attached to the sensory receptor organs of driver 24, namely to the eye 22, to the ear 44, and to the temple 48 of the head.
  • One wakening means is a liquid dispenser 30, preferably one for each eye 22, for wetting the eye.
  • the dispensing may include splashing.
  • liquid dispenser 30 preferably is disposed above the eye 22, for allowing dispensing the liquid by gravity only.
  • a horizontal protrusion 42 may extend from the top of rim 38, for disposing liquid dispenser 30 thereon, for allowing dispensing the liquid by gravity only.
  • Bar 32 of frame 36 may include a liquid tank, from which liquid dispenser 30 may dispense, via pipes (not shown), the liquid.
  • Another wakening means is a loudspeaker 14, which may be disposed proximate to the ear of driver 24.
  • Another wakening means is a vibrator 46, which preferably may be disposed proximate to the temple 48 of the head of the driver 24.
  • Fig. 5 depicts additional elements of the goggles of Fig.
  • the term "gyroscope” refers herein to a device for measuring or maintaining orientation, based on the principles of angular momentum.
  • a mechanical gyroscope includes a spinning wheel or disc in which the axle is free to assume any orientation. Although this orientation does not remain fixed, it changes in response to an external torque much less and in a different direction than it would without the large angular momentum associated with the disc's high rate of spin and moment of inertia.
  • the device's orientation remains nearly fixed, regardless of the mounting platform's motion, because mounting the device in a gimbal minimizes external torque.
  • Goggles 10 may further include a set of sensors 52, in addition to cameras 12, for detecting that driver 24 might not be in full activity.
  • One of the sensors may be a gyroscope enumerated also 52. Since driver 24 wears goggles 10, gyroscope 52 like camera 12 is stationary in relation to the head of driver 24. Thus, an abnormal motion of the head of driver 24, typically being extreme motions or a fall of the head, may indicate that driver 24 might be sleepy.
  • the additional sensors 52 may include a fever sensor, a blood pressure sensor, and a heart rate monitor.
  • Goggles 10 may further include a transmitter (included within the electronic circuit 18), for reporting to an external system, which may constitute the authorities, that driver 24 might not be in full activity.
  • the transmitter (18) is essential for reporting that the driver is not in full activity, due to a medical event, such as by high fever, blood pressure, heart attack, detected by the fever sensor, blood pressure sensor, and the heart rate monitor (52), respectively.
