The app, designed to look just like a PECS™ communication book permits a teacher to practice picture discrimination with one or several learners within a single session. Touching the correct icon results in immediate visual and auditory feedback from the device in a manner far quicker than a teacher could react. If the learner touches an incorrect icon, there is no significant feedback. A correct picture selection results in access to a desire item or activity!
