You used to be able to get 'soft shutter release' attachments that screwed into the threaded cable release socket atop the shutter release - or you could use the domed cover from a bathroom mirror screw. There must be many small items that could be affixed to the shutter release button to raise its profile slightly.
FWIW, on my desktop computer the 'On/Off' switch is recessed, presumably to prevent accidental pressing. I found this unhelpful, so scrounged a small wooden self-adhesive ladybird from a friend and attached that. Problem (if such it was) solved. This might also give a camera a slightly quirky look, if that is acceptable.
