Typically, you would choose number of buttons on a page based on what person can see and physically access NOT based on receptive or cognitive ability. Was she able to access the buttons on the original page set up? How was she using it? It sounds like if you are recommending that she continue using WP42 setup that you feel that she was using it ok, or that she can learn to use it, so I agree that she should continue with that. So they've deleted all of the vocabulary from TouchChat and limited her to just 10 buttons? Is that right? Is there a school SLP involved that you can collaborate with? Sorry, I don't have time to write you as detailed a reply as I'd like but here are my initial thoughts: Does anyone have any research supporting the TouchChat vocabularies and how they were designed? I’m just wondering if anyone else has come across this (using TouchChat as a means for an electronic custom core board) or have done this themselves and could provide me some insight as to the benefits of doing this. I would like to have as much research, evidence, and data to support my recommendation. However, I want to do this in the most positive and collaborative way. My clinical recommendation is to use the actual WordPower42 vocabulary pageset that is part of the TouchChat application. Dad and her outside therapy team including myself would like to add additional vocabulary to her device as well as vocabulary that will allow her to use her device for a variety of communicative functions (greetings, answering personal questions, commenting, directing others). There are no colors for the backgrounds of the cells. She has 2 buttons that open up to fringe vocabulary: drink->juice, water sensory->music, squeezes. Some of the words include: go, away, different, want, more, not, yes, no, feel, feelings, eat, drink. It appears that they deleted the WordPower42 vocabulary in order to use the cells/grid to program in their own words. Her device is owned by school and they are the sole programmers of the device. I see her for outside private speech therapy. I am working with a 9 year old who has an iPad with the TouchChat application on it.
