That’s the best computer. The best interface is no interface.
See the router that guides you as you make the cut.
See how the person makes the design and the router follows that design. See how the router is assisting.
See how the cutter follows the lines she meant to draw, and interpolates the proper line to cut.
But you don’t see a computer that you have to interact with.
The more you get back to the computer guiding you, assisting you, the easier and better it is. See auto-tuning guitars. See backup warning radar in cars. See Nest thermostats. See tiny little adjustments made for you without you noticing, enabling what you intend instead of what you did.
They say the devil is in the details. Sometimes subtle details are a place to shine.
You have to speak the user’s language. “Bookmarks” are what you call them if
you use Netscape of Firefox – most users these days know the term “favourite”
instead. Half of his population (? users) didn’t know what a bookmark was.
