Gorenje (a Slovenian business) did a project where they used silicone heat resistant covering for the stove top with cutouts where the pans go. The model of stove they used also had physical knobs to control the heating circuits. I don't think Gorenje make a hob with knobs at this time.

I really like the idea of a silicone template cover for the hob and if the time comes that it is needed I will have to try and find the materials to make one.

We have an induction hob made Smeg (an Italian business) that has knobs with very good tactile feedback. The have a distinct direction to their shape, the off position has a notch feel to it and the features (extra high power and accelerated heat up) are accessible by turning the knob until it hits a sprung resistance point, either clockwise or anti-clockwise respectively, and then an audible ping once the feature is selected. The edge of the hob is framed in stainless steel that contrasts well with the black of the main surface. This unit is still available in the UK and it works well for a cook with a severe visual impairment. Sad to say there doesn't seem to be an alternative so if Smeg stop making this design and we need a replacement we will have a problem.

I really like how easy induction hobs are to keep clean because they are flat. The surface never needs to get hotter than the pans do and these heat doesn't extend much beyond the underside of the pan. Spills usually don't burn into stubborn crusts They also provide a nice flat surface for putting things down on. We did have to replace most of our pans when we got the hob because of the way the hob works.
