Here’s a way to use the dial scanner to help children make choices during play. Hook up a very light-touch switch to the dial scanner. Prop the child’s arm to enable easy access. Use toys such as a Mr. Potato Head with pieces. Attach piece with Velcro onto the dial Plexiglas. You can add pieces as choice making advances. To encourage better scanning you can alternate positioning of the pieces onto the Plexiglas.
