Have you heard about CoreScanner™! We LOVE it! It is a vocabulary system designed for switch scanning based on the Words for Life™ vocabulary. We have several students who had never used two switches to scan before trying the Accent 1000 or Accent 1400 with CoreScanner™. After an initial model with the system, 5 out of 6 students we tried it with were scanning to speak within the first 30 minute session using the Cornerstones vocabulary.
Check out the CoreScanner™ video that PRC created to demonstrate the system.
My favorite part about CoreScanner™ is that it allows users to gradually increase vocabulary while maintaining consistent motor plans. At the Cornerstones level, users select words from a field of 8 using linear scanning. At the Pathway level, users use block scanning to select words from 9 word blocks with a total of 84 locations. At the JAM and Blast levels, users have access to word families and the ability to add custom vocabulary.
So far, all of my students have used two switches at either the head or with their hands to access CoreScanner™. You should definitely check it out and consider for students who need switches to access AAC systems!
