Electric Car Dasboard
CONCEPT — 2021
What if a pure touchscreen car dashboard integrated with a simple control dial. Does it work or doesn't? Let's find out!
Introduction
Nowadays many car manufacturer believes car dashboard merely with touchscreen. This is not so userfriendly in every cases, particularly for the driver, he/she has to glance at the screen to recognize funtions, in addition there is no physical feedback in case we push aside. In this study I test it would be work if I put a control knob with magnetic attachment on a touchscreen to control functions with drag, push, twist and drag to the right places.
Start designing
In the first round I collected and grouped all of the basic functions which need to put on a car dashboard. All this for without claiming completeness, the aim was to try an idea not building a perfect working car dashboard device.
The idea
The basic idea was to combine a conventional touchscreen with special magnetic fields and a control knob with magnetic attachment.
How it works?
Simply dragging the knob to the proper place it could be activated the function connected to the place and you can set the value with twiating the device. If available to reach more function, push the button on the top of the knob to change between them.
Prototyping
The test device was a Microsoft Surface Go tablet so I designed the user interface elements adjusted to it's proportions.
I prototypized as much interface element as possible to make the dashboard surface almost lifelike.
Try it!
I share the Figma prototype for the public, so you can try it on this link. You can change between the modes with clicking the time.
(It has made with Figma interctive components beta, so sometimes a bit buggy)
And what if you don't need the control knob? Simply get rid of it, you can set everything on the touchscreen.
Epilogue
As an experiment this is definetely an interesting concept idea. The prototype was easy-to-use, of course an important thing to reduce the learning curve in everyday life. But I think the difficult part in this project is to make enough strong magnetic contact between the screen and the knob, not to fall off while the car is shaking. I hope it would be solved by smart engeneers. 
Disclaimer
First of all I have to admit that, is it not a perfectly polished project, it just a study about an idea I wanted to try. I'm a UI designer with some UX skills, I didn't do a research before this project and it wasn't user tested.
