I have a sit-stand desk from Costco with capacitive height controls set under the glass top off to the right. The problem is not so much accidental human touches, but setting anything slightly conductive on the switch will trigger the height control, including things like computer mice and ceramic coffee mugs (as long as they have some liquid in them), exactly the sorts of things that a right-handed person might want to set on the right corner of the desktop.
The desk is otherwise great and was really inexpensive for what it is but it's a super frustrating design decision.
It's similar in my fridge. Instead of a temperature dial, it has touch sensitive buttons, so the slightest brush with a jar drops the temperature or puts it into fast-chill mode, which will freeze the vegetables in the drawers.
