The way they're set up is not very useful. First, the ones I've used either have a wireless control panel mounted somewhere you have to flip down a little panel to use, or little controls attached to the seat, which require that you turn your body and operate the controls with one hand. Depending on how you're impaired, if the hand you need to control the toilet is not functioning, you're kind of hosed. Second, if you have any mental impairment, are you really going to go through menus with small icons to control the temperature and pressure of a stream of water directed to your nether parts? Finally, the auto-clean/auto-dry toilets still generally require one last wipe to clean up. Think about it this way, if you're baking a cake, and if you smear frosting on your arm, are you just going to rinse your arm with water and call it day, or are you going to rinse it and then wipe the area dry with a towel?
