As a wheelchair user I love lifts but I can't reach the buttons - especially the ones at the top... I think it wouldn't be difficult to make a remote control like for TV to allow me to type the floor number I need (or alarm button etc.) and send it to a receiver built into the panel. Buttons would operate as normal for those who don't need the remote. This might also help visually impaired as they could have a braille or voice activated remote. People who need the remote could buy one...
