A wheelchair user with a condition which causes contractions of his joints could not get a mobile phone to either ear, both of which are also very sensitive. He wanted the privacy that hands-free loud-speaker mode would not have given him.
A handle with attached phone-holder was made from telescopic aluminium tubing. At the phone-holder end a foam pad takes the weight on his shoulder. The fitted handle enables him to speak and listen without feeling he is being overheard.
