The William is actually quite problematic from the UX point of view, most notably:
- There's a disconnect in space between the space being heated, the diagram of the heating patterns, and the heat control diagram. So you have three points of attention instead of, ideally, one, and traditionally, two.
- The whole interface has no undo. If I remove a heating space, reset clock, recalibrate weight, there is no going back.
- Removal of cookware deletes all associated data and programming.
- Touch interfaces while cooking are horrible and I hope they will never win.
Though, of course, the concept is from 2010 and the idea to add programmable heat curves (or, ideally, IFTTT of cooking) is a nice one.
