User Interface

The user interface (UI) is the Achilles heel of car design. Outdated, inflexible, and old upon arrival, UI has often been an unintentional time machine, showing drivers of even the newest cars what phones in 1997 looked like. And given that this has been the case, society at large has accepted it. For the last fifteen years (give or take), UI has been a bridge too far, both in usability and appearance. Is a modern, capable, well-designed, future-proof UI really too much to ask?

No. No it is not.

Both the point of contact between driver and vehicle, and a connection to the world outside, the UI is where the driver acts and reacts, plans and responds, and in doing so shapes their entire driving experience.

One of Polestar’s driving forces is to solve challenges and show what’s possible through innovative solutions, modern technology, and ground-breaking design. The UI in the upcoming Polestar 2 is an embodiment of this attitude.

Google Automotive Services, Standard

The Polestar 2 will be the first car in the world with a truly future-proof software setup, meaning that not only will it be cutting-edge upon release, it will update often and automatically. How many people would ever buy a smartphone if they knew it would never update? Polestar believes that people should have the same requirements of their cars. With an Android system featuring Google Automotive Services, an over-the-air update format (made simpler by the fact that the Polestar 2 is always connected to the internet), and full access to all automotive-optimised apps from Google Play including Google Maps and Google Assistant, the Polestar 2 will update as easily and with the same frequency as a smartphone. 

It will also come equipped with other features sorely missing in automotive UI. The first of which is a functional voice command system. There are, as of 2018, 160 distinct dialects of English spoken throughout the world. And as of 2018, voice command systems in cars can handle four of them. Not so in the Polestar 2. With Google, who have been perfecting their Assistant for years, commands will be heard clearly regardless of accent. Don’t worry, people of the Cape Flats, Abercraf, South Ballachulish, and Ruatahuna. Polestar hears and understands you. 

The second feature is something being used in cars all over the world, but on a secondary device. Google Maps is the undisputed champion when it comes to navigation, a web mapping service which is unparalleled in terms of accuracy and real-time information. It was the natural choice to make Google Maps the pre-installed navigation software for the Polestar 2, offering the best possible solution while removing the need to consult a phone while driving.  

And speaking of smartphones, both Android users and iPhone owners (though Apple CarPlay) can wirelessly connect their devices to the Polestar 2, enabling access via voice commands and the centre console. 

This is all part of the overarching idea that this car is a seamless integration into modern life. Not only is it packed with the most current tech, it will stay current. No more having to remain content with outdated software. Retro has its place, of course, but that place isn’t in a Polestar.

Intuitive, Uncluttered Design

There were a number of other hurdles on the way to the delivery of this UI, not the least of which was design. “UIs tend not to be driver oriented,” says Amil Gasanin, the graphic designer responsible for the Polestar 2 UI design. “They also have comparatively small touch areas, taking more of your attention which should be on the road.” Accidents can occur from the smallest lapse in concentration, and many a fender has been bent as a result of trying to tweak the in-car temperature or listen to a different song. One of the simple yet impactful design choices was to enlarge the buttons. “A bigger touch area is always beneficial, and helps to minimise driver distraction,” explains Aloka Muddukrishna, who is responsible for Polestar 2’s User Experience.

Finally, a UI which is intuitive, well designed and driver-centric.

Another UI design issue is how to structure menus. Navigating a labyrinth of collapsible menus is taxing enough even when you aren’t behind the wheel of a vehicle. It’s positively dangerous to build menus in an UI which are so convoluted that it makes scrolling through them akin to leafing through Leonardo Da Vinci’s recovered manuscripts. Polestar’s answer to this was simple and elegant. Instead of unwieldy collapsible menus, you have a four-tile grid system. Each tile has default app groupings which can be customised, and three large buttons for quick actions; shortcuts which avoid tedious (and dangerous) slogging through menus. Instead of riotous colour schemes and frenetic font combinations, it’s minimalist and designed for optimal performance. Pure Polestar, in other words.

Another design choice which makes the UI more driver-centric, while reducing time spent not focusing on the road, is a screen containing the apps accessed most often. “This reduces the amount of interactions needed to reach the most-used functions, for example the 360° camera,” continues Muddukrishna.

We’ve developed a unique little web app, using the Polestar 2’s UI as a framework. We recommend using a newer tablet or phone with a large screen. Download and start exploring!

To talk further about the UI, the focus now needs to shift to access functionality. Namely, the phone-as-key solution. The Polestar 2 will make use of the driver’s phone to access the car, leading to greater accessibility and fewer hardware complications. It’s yet another innovation which allows the Polestar 2 to adapt to the driver, and not the opposite. The UI wakes up incrementally, responding to the presence and position of the driver and mimicking different key positions. It is the driver, and their phone as authentication device, which enable the UI to be so interactive. As the driver approaches, the car senses the presence of the phone and the display wakes up, showing limited information such as charge status and remaining range. Once the driver enters the car and sits down, intelligent sensors in the driver seat signal to the UI to wake up even further, granting access to all of the car’s functionality short of driving. Finally, the brake pedal is depressed and the shifter is moved, and the engine starts.

The UI is how the driver communicates with the car, and in doing so, shapes and controls their experience. With the Polestar 2, there’s finally a UI which is as modern, responsive and well-designed as the car it’s in.
