Instead of putting light switches/dials on the wall, why not make them floor tiles, so they're out of sight? The switch-tile is against the wall, so the chances of turning the light off accidentally are reduced. They would have some identifying marking above them (a window, a wall corner, a doorframe, a picture/painting, etc.) to be recognizable.
If your home has hardwood floors, the board next to the wall is the switch. For carpeted areas, the plain tile is placed under the carpet, also with something to identify it.

In place of the dimmer switch dials, the tile/board is pressure sensitive, so that the harder you step on it, the brighter the light gets. The light is turned off by stepping on one of the corners, which have a spring-loaded ratchet mechanism (like a foot-operated parking brake on some cars, I think).
