Jaguar Land Rover has developed new contactless touchscreen technology, designed to comply with demands in the post-Covid world.
The system has been designed to help keep drivers’ eyes on the road and reduce the spread of bacteria and viruses.
The Midland car maker, which has its global headquarters in Coventry, has developed the new system in partnership with engineers at the University of Cambridge.
The patented technology, known as ‛predictive touch’, uses artificial intelligence and sensors to predict a user’s intended target on the touchscreen – whether that’s satellite navigation, temperature controls or entertainment settings – without touching a button.
The system forms part of Jaguar Land Rover’s Destination Zero mission – a long-term ambition to make its vehicles safer and the environment cleaner and healthier.
It has been developed to fulfil the requirements of a post-lockdown world, where greater emphasis will be placed on safe, clean mobility where personal space and hygiene will carry premiums.
It forms part of a ‘joined-up’ approach by the car maker.
Jaguar Land Rover vehicles are already designed to help improve passenger wellbeing and innovations include a Driver Condition Monitor, engine noise cancellation and cabin air ionisation with PM2.5 filtration to capture ultrafine particles and allergens.

Predictive touch represents another step forward as the wider landscape of mobility is addressed, from how customers connect with mobility services, to the infrastructure required to enable fully integrated, autonomous vehicles.
Laboratory tests and on-road trials have demonstrated the predictive touch technology could reduce a driver’s touchscreen interaction effort and time by up to 50%, as well as limiting the spread of bacteria and viruses.
Uneven or poor road surfaces can often cause vibrations that make it difficult to select the correct button on a touchscreen. This means drivers must take their attention away from the road, increasing the risk of an accident.
The technology uses artificial intelligence to determine the item the user intends to select on the screen early in the pointing task, speeding up the interaction.
A gesture tracker uses vision-based or radio frequency-based sensors, which are increasingly common in consumer electronics, to combine contextual information such as user profile, interface design and environmental conditions with data available from other sensors, such as an eye-gaze tracker, to infer the user’s intent in real time.
How NatWest is supporting BusinessLive
NatWest is the national partner of BusinessLive.
The banking group is teaming up with BusinessLive on a series of events throughout the year aimed at entrepreneurs and business leaders.
Alongside a wide range of banking services, NatWest offers businesses specialist sector knowledge in areas such as manufacturing and technology, as well as access to specialist entrepreneurial support.
Lee Skrypchuk, human machine interface technical specialist, at Jaguar Land Rover, said: “As countries around the world exit lockdown, we notice how many everyday consumer transactions are conducted using touchscreens - railway or cinema tickets, ATMs, airport check-ins and supermarket self-service checkouts, as well as many industrial and manufacturing applications.

“Predictive touch technology eliminates the need to touch an interactive display and could therefore reduce the risk of spreading bacteria or viruses on surfaces."
He added: “The technology also offers us the chance to make vehicles safer by reducing the cognitive load on drivers and increasing the amount of time they can spend focused on the road ahead.
"This is a key part of our Destination Zero journey.

This software-based solution for contactless interactions has reached high technology readiness levels and can be seamlessly integrated into existing touchscreens and interactive displays, so long as the correct sensory data is available to support the machine learning algorithm.
Professor Simon Godsill from Cambridge University’s department of engineering led the project.
He said: “Touchscreens and other interactive displays are something most people use multiple times per day, but they can be difficult to use while in motion, whether that’s driving a car or changing the music on your phone while you’re running.
“We also know that certain pathogens can be transmitted via surfaces, so this technology could help reduce the risk for that type of transmission.”
