Ford Unveils Holographic Technology to Keep Eyes on the Road
3 min
Ford, working with Scottish company Ceres Holographics, showed off last week what could become the future of head-up displays, or HUDs as they’re commonly known.
HUDs almost magically display useful information such as speed and turn-by-turn directions on the lower part of the windshield, where it can be seen without taking the driver’s eyes off the road. For years now, automakers and their suppliers have imagined an autonomous world in which cars drive themselves, and the glass currently needed to see traffic could be turned into big display scenes at will. But the arrival of full self-driving is still a long way off.
At a conference in Detroit, Ford displayed an interim step: what might be called HUD 2, a bright, clear display stretching across the windshield with three sections, two for the driver and one for the passenger. The latter, which could include projected video, would not be visible to the driver.
Andy Travers, the CEO of Ceres Holographics, says that the new display possibilities could be interactive, and help solve the dangerous situation of driver distraction using current controls.
“It’s compelling cost-wise for automakers to put everything on the screen,” Travers says. “And they’re hiring programmers who are used to working with computers, not mobile cars that need to have drivers watching the road. We think it’s a lot better to make choices from projected images on the windshield than having to look away to a centrally mounted screen.”

The windshield incorporates Ceres-developed (with Eastman and Carlex) thin-film technology that is produced with embedded holographic optical elements and then sandwiched between laminated glass sections to enable a transparent display of any kind of information. Travers says the film will not discolour over time. An inexpensive LED projector, technology in use now, is built into the instrument panel.
Regulators are taking notice of the distraction problem. According to Matthew Avery, director of strategic development at the safety agency Euro NCAP, “the overuse of touchscreens is an industry-wide problem, with almost every vehicle maker moving key controls onto central touchscreens, obliging drivers to take their eyes off the road and raising the risk of distraction crashes.”
Janice Tardiff, a coating application technical expert at Ford, says the passenger display on its initial prototype vehicles would target entertainment and possibly business applications.
The driver would get fuel or charge level, speedometer, navigation, and, on the centre display, points of interest and music. In a customer clinic testing the technology, participants liked the idea of being able to see sports events and movies, but weren’t sure that the clarity was sufficient for business applications. Some wanted the displays to be bigger.
Use of the film has been thoroughly tested and approved for next-generation HUD use, Tardiff says. The next steps are to improve colour, brightness, and resolution, optimise the size of the displays, and ensure good performance under different light conditions, she says.
HUD was an option on the Oldsmobile Cutlass in 1988, and it’s been steadily evolving since. Other companies are working on holographic technology, including Hyundai, Stellantis, Jaguar Land Rover, and General Motors. Technology shown by a U.K. company called Envisics on this year’s Chrysler Halcyon EV concept car imagined images on auto windows that would show points of interest along the chosen route, allow video calls en route, and map constellations in the night sky.
But not all of this would be able to go into current cars.
“While all this visual information is probably too distracting for a driver in control of the vehicle, it may not be when the vehicle is operated in an autonomous Level Four mode,” according to Envisics. “At this level, the driver can relax and utilise these functions and features.”
But some of it will be seen soon. A Chrysler/Dodge spokesman, Darren Jacobs, said via email, that “select design elements and features [seen on the Halcyon] like the head-up display and SmartCockpit are ready for production and will be included in Chrysler’s first all-electric vehicle.”
The Ford-Ceres technology is possible for production today, and it could lower driver distraction and prove satisfying for auto buyers—especially if image clarity can be improved.

With interest booming, wellness experts and pool builders have seen more homeowners hoping to take cold therapy immersion into their own backyards.

Cold plunges have gone from fringe curiosity to full-blown cultural phenomenon, the wellness world’s equivalent of a headline-grabbing breakout star.
Adherents slip into icy water on a daily basis, chasing an electric jolt of clarity that feels like a flip has been switched inside your brain.
Dedicated cold plunge practices are everywhere from upscale fitness studios and pro sports locker rooms to renowned wellness destinations such as Mountain Trek Health Reset Retreat in British Columbia.
Considering the ever-expanding assortment of companies flooding the market with cold plunge tubs and other custom devices dedicated to achieving icy bliss—with costs potentially reaching into the tens of thousands—some homeowners are tempted to use their swimming pools as an alternative.
“We’re absolutely seeing more homeowners use their pools as year-round cold plunges, especially in colder climates,” said Nick McNaught, CEO and co-founder of Toronto-based Stay Unbounded, which offers cold exposure workshops, retreats and certifications.
“The motivation is often simplicity and cost. If the water is already cold, people see value in keeping the pool open longer or winterizing it differently to support cold exposure.”
Suzanne Vaughan, president of Massachusetts-based pool builder SwimEx, points out the inherent convenience that comes with taking a frosty dip out back.
“From what homeowners tell us, the appeal of a cold plunge at home is less about chasing extremes and more about having a simple ritual that’s always available,” she said.
“It’s quick, accessible and easy to build into a daily routine.”
Among new clients Vaughan works with, year-round cold plunge use is usually planned from the start rather than as an afterthought.
“More are choosing indoor pools or small attached structures because that makes temperature control, equipment protection and day-to-day use much easier in colder climates,” she said.
If someone is thinking about using an existing home pool as a cold plunge, the main questions are likely to involve practicality and protection.
“Larger volumes of water take more energy and time to keep at colder temperatures, and you need a plan to protect plumbing, finishes and equipment from freeze–thaw cycles,” she added.
“Whatever the design, you want a system that’s built for the temperature range you have in mind, and a pool professional who can help you winterize safely.”
One such professional is Hunter Gary, a certified master pool builder and owner of H2 Outdoor Living in Tennessee.
“Most everyone has a ‘number’ in degrees when it comes to cold plunging. When a client asks our company to design a cold plunge for them, I ask ‘what’s your number?’” Gary said.
“A smaller body of water or cold plunge vessel may be much easier for maintaining a balanced temperature…but if using a pool gets you excited about a more serious approach to inviting this wellness experience in your life, then go for it.”
Amy McDonald, owner and CEO of Under a Tree, a wellness consultancy, said transforming a pool into a plunge might not be worth time and investment
“It is almost impossible to retrofit a standard swimming pool into a cold plunge,” she said.
“The energy and money to do it properly is greater compared to just creating a complimentary contrast circuit.”
A proper setup needs to be exceptionally cold, she noted, so depending on where the pool is located it might not get chilly enough to provide optimal health benefits.
“That could work in northern areas of the U.S., but it takes a lot for a pool to generate and keep that kind of cold, not even considering if the pool ices over,” she said.
McNaught echoed those concerns, citing how home pools aren’t designed specifically for cold plunging, so temperature consistency, cleanliness, ease of access and safety become important factors.
“Dedicated cold plunge setups offer more control, smaller volumes and lower ongoing maintenance,” he said.
“For many people, a pool works as an entry point. Over time, those who commit to the practice transition to a dedicated setup because it better supports frequency, comfort and long-term use.”
Beyond geography and climate, industry experts pointed out other challenges homeowners are likely to face.
“Pools are saturated with chlorine and other chemicals that directly absorb into the bloodstream. The advantage of many cold plunges is that no chemicals are required for residential use,” said David Haddad, as the co-founder of Oregon-based BlueCube Wellness.
“Constant ozonation and filtration is enough to kill organic compounds without exposure to sanitizing chemicals.”
Most cold-plunge systems are monitored to stay between 50-60 degrees Fahrenheit—with experienced plungers often preferring lower temperatures.
While “the ultimate experience might be a glacial lake in Finland, unfortunately that’s a bit out of reach for most of us,” said Andreas Stelluti, co-founder at Texas-based Colderatti, whose vessels feature the world’s first chemical-free cold plunge technology, powered by a triple filtration system that removes 99% of impurities to provide a system with drinking-quality water.
“Having a cold plunge at home brings that experience to your backyard, making it very easy and accessible, so you have the ability to make it part of your lifestyle,” he added.
Stelluti noted that as spring arrives and clients’ home pools start to warm up again, they begin to miss the cool water.
“Many say ‘I really need this to be part of my lifestyle year-round’ and that desire for consistent, accessible cold immersion is what motivates them to invest in a dedicated cold plunge setup,” he explained.
“Unfortunately, you can’t use your pool as a year-round cold plunge during the summer. Especially not here in Texas.”
