The idea came from interpreting the data in a study that showed how the majority of drivers, 74% to be precise, admitted to feeling oppressed or stressed for various reasons, including traffic, imperfect road conditions, roadworks, and so on. Thanks to the new Jaguar-Land Rover system, the driver’s mood is monitored and interpreted through a camera which reads his/her facial expressions, while biometric sensors control and assess the mood to then, as a consequence, adjust the range of functions inside the compartment, including heating, ventilation, air conditioning, media and lighting. The settings in the compartment change by reacting to the driver’s facial expressions to help reduce stress. By having a refined predictive analysis system, over time, the app will learn the driver’s preferences and adjust the settings in an increasingly personalized way. It will change them when necessary, for example, modifying the colour of the interior lighting can be more relaxing, as can selecting a favourite playlist or lowering the temperature in the compartment if signs of tiredness are discerned. The experiments conducted by Jaguar, however, are not only for the front seats because cameras can also be mounted into the headrests to monitor the back-seat passengers. In this case, at the tiniest sign of tiredness, the system could lower the lights, darken the windows and raise the temperature to help the back-seat passengers fall asleep. «On our road towards the self-driving cars of the future» says Steve Iley, Chief Medical Officer at Jaguar-Land Rover, «we will be paying even more attention to the driver. With a holistic approach towards the single driver and by putting into practice what we have learned about a person’s well-being in the last 10 or 15 years of research, we can guarantee that our customers at the wheel will be comfortable, concentrated and ready for any driving scenario that may arise, including journeys on the most monotonous motorways».
