Can anyone help me on this? I'm trying to design a simple phone system for a group of adults with learning disabilities. We need to replace standard phone keypads with bigger keypads that will take picture stickers so that, say, you push the button with a car on it to dial out for a taxi. Plus each button should default to memory dial, so that you can only choose one of 10 pre-programmed useful numbers. Additionally, it would be useful if there was someway of extending the keypad of a mobile phone (bluetooth device?) so that they could have similar system for a mobile phone. You could possibly do this simply by having a keypad device that emitted the various dial tones for the niumbers. Can you buy such a device anywhere? (I need something that doesn't imvolve any soldering, because my soldeing is rubbish).
