This will be huge for automotive touchscreen applications: I have no doubt it will save lives. With current touchscreen interfaces, you rely almost solely on visual cues and feedback to make correct inputs. Not a good situation while driving, when you need as much visual attention as possible focused on the road. The best interfaces for operating complex or dangerous machines have fixed, haptically identifiable refer…
Similar to kiba's comment below, but perhaps a step in between, it would make sense for car designers to look at other similarly complex machines that require the operator's constant attention to the outside world before innovating blindly. HOTAS (Hands on Throttle and Stick) as a concept has been adopted almost exclusively in fighter aircraft - and extended into Formula 1 and Indy cars as well - for this exact purpo…
Nowadays it's much more likely that you spin a knob or repeatedly press a button to set the temperature, and instead of the setting being indicated by a combination of position and color/text, you likely have only a numeric value, an exclusively visual indicator.
Not only does the digital, numeric value (usually in degrees F or C) provide a (possibly) unneeded level of precision, it's a visual-attention sink.
The "glass cockpit" of the Tesla I have to believe is even worse in this context. However, given its extreme versatility, I doubt the touchscreen will be going away. If a screen interface can be designed to require less attention, and I believe it can be, it's possible that we can gain all the promised flexibility of glass without it becoming a safety hazard.
Thanks for the HOTAS reference, btw. Hadn't heard of that.
