Most importantly, Expressionist does not require learning by using picture encoding (which is a serious flaw in most picture-centric system).

Over 120 commonly used expressions are organized into 7 categories:

- Common phrases/Greetings
- Feelings/Emotions
- Senses
- Health/Well-being
- Actions/Activities
- Requests
- Questions

In addition, there are 1000+ commonly used nouns included to make Expressionist a very flexible and practical learning tool.  All expressions and nouns come with natural voice audio output.
  































Instead of typical sentence construction approach (like in common PECS book or AAC), Expressionist uses the composite picture approach to illustrate either an expression or an concept.
































Expressionist also focuses on using change of visual physical states to illustrate action concept directly. This eliminates the use of any confusing drawing nor picture encoding.

Simply put, what's in the picture is exactly what needed to be expressed.  
































For expressions that may refer to specific item or location, a scrolling window is displayed to allow very easy browsing (over 400+ items may be browsed in each expression).
































Simply click on any item to get audio output and to complete the sentence.
































Due to iphone/iPodTouch's screen size limitations, it is possible that the user may like to zoom into a particular item.  Simply drag up or down on the item's picture to display the high-quality view.
































In cases where association is needed, the associated object is displayed in the background. In this example, there would be no confusion that this orange red bottle is specifically for laundry washer, not for drinking, cooking, planting nor plumbing.
































Or in the case, instead of typical "pointing to the watch" to ask time, the expression prompts to fill-in-the-blanks.
