The 18-month old client had a severe eating problem making eating a frightening experience. It was suggested that if music played when he put a spoon in his mouth, he may be encouraged to eat.
A gold-plated wire was fixed to a plastic spoon and connected by a flexible lead to control electronics. A second wire led from the electronics to a wrist strap. Inserting the spoon into the mouth closed a circuit, causing coloured lights to flash and music to play.
The system is a great success, with the client eager to put the spoon in his mouth.
