Point to Pictures (PTP) is an Augmentative Communication *training* app designed for those persons *learning* to point/select a picture on an iPad in order to *get* that item in real life, and thus might help those that might eventually use the iPad to communicate via pictures and/or text.
Using a library animations and pictures of real-world consequences, the learner learns to pair their switch action with receiving the actual item (food, toy, activity, person, song, etc.). PTP/STP *wants* you to add your *own* pictures that are personally motivating to *your* learner, because many times, only a few specific things really get through to a learner.
Before you go to a real communication program, which usually has no fun content, and no hand-holding, you will find PTP/STP to be a necessary step from cause/effect to more advanced communication apps.
*STP = the switch/scanning version, Scan To Pictures
