The automaker Jaguar is developing a battery of technological innovations to optimize the concentration and well-being of drivers to limit the number of accidents on the roads. These research projects are grouped in a global intiative called Sixth Sense. Among them: a technology from NASA that measures brain waves through the hands.

  • Jaguar Land Rover's pioneering Mind Sense project is researching measuring  brainwaves to monitor driver concentration in the car
  • Researchers are developing a Wellness Seat in a Jaguar XJ which analyses the driver's heart rate and breathing to monitor driver health and stress
  • Touchscreens that predict which button you want to press as the user's fingers are in mid-air -  to minimise time spent with eyes off the road
  • Jaguar Land Rover researchers use new haptic accelerator pedal to communicate hazards to the driver

Mind Sense

The basis of Jaguar Land Rover's Mind Sense research is to see if a car could effectively read the brainwaves that indicate a driver is beginning to daydream, or feeling sleepy, whilst driving.

The human brain continually generates four or more distinct brainwaves at different frequencies. By continually monitoring which type of brainwave is dominant, an on-board computer could potentially assess whether a driver is focused, daydreaming, sleepy, or distracted.

The most common method for monitoring brainwaves is close to the source using sensors attached to a headband, something that would be impractical in a vehicle. Jaguar Land Rover is investigating a method already used by NASA to develop a pilot's concentration skills and also by the US bobsleigh team to enhance concentration and focus.

This detects brainwaves through the hands via sensors embedded in the steering wheel. Because the sensing is taking place further away from the driver's head, software is used to amplify the signal and filter out the pure brainwave from any background 'noise'. Jaguar Land Rover is currently conducting user trials to collect more information on the different brainwaves identified through the steering wheel sensors and will involve leading neuroscientists in the project to verify the results.

Driver Wellness Monitoring

Jaguar Land Rover is assessing how a vehicle could monitor the well-being of the driver using a medical-grade sensor embedded in the seat of a Jaguar XJ. The sensor, which was originally developed for use in hospitals, has been adapted for in-car use and detects vibrations from the driver's heart beat and breathing.

Monitoring the physical health of the driver could not only detect the onset of sudden and serious illness that may incapacitate the driver, but also allow the car to monitor driver stress levels. This would then allow the car to help reduce stress, for example by changing mood lighting, audio settings and climate control.

Predictive Infotainment Screen with mid-air touch

Jaguar Land Rover is working on new technologies that increase the speed and efficiency of the interaction between the driver and the infotainment screen. The aim is to reduce driver distraction by minimising the amount of time the driver's eyes are on the screen

Jaguar Predictive Infotainment Screen prototype uses cameras embedded in the car to track the driver's hand movements and this enables the system to predict which button the driver intends to press. This allows successful button selection to take place in mid-air, which means users wouldn't have to touch the screen itself.  In user trials this increases the speed of successful button selection by 22 per cent and therefore reduces the amount of time the driver is looking at the screen with their eyes off the road. 

The system could also use mid-air touch to provide the driver with a sensation, otherwise known as haptic feedback, that their button selection has been successful. Mid-air touch uses ultrasonics to create a touch sensation in mid-air without the skin needing to be in contact with any surface. The sensations could include a 'tap' on your finger or a 'tingling' on your fingertips. As touch provides an immediate response to the brain, there will be no need for the driver to glance at the screen for visual confirmation which would help keep their gaze on the road ahead.

HAPTIC ACCELERATOR PEDAL

Haptics could also be used to communicate with the driver through the accelerator pedal to increase the speed of response and to ensure the correct action is taken.

To create these sensations in the accelerator pedal, an actuator sits at the top of the pedal arm and allows for vibrations or pulses to be passed through to the foot of the driver. The technology also uses a torque motor which can create resistance in the pedal feel.

This resistance could be used to notify the driver that they are pushing the accelerator through a speed limit. Alternatively, if you were crawling along in traffic a timely warning through the accelerator could prevent you bumping into the car in front.
