Which two augmentative systems require selecting and sequencing icons to form messages?

• A. Lingraphica and Dynavox
• B. PCAD
• C. C-VIC and Lingraphica
• D. Dynavox and PCAD

Answer: (C)

Building a message by selecting icons in a specific order is the defining approach of these systems. Lingraphica presents a grid of pictures that represent words or concepts, and you assemble a sentence by tapping icons in the sequence you intend to say, so the device vocalizes your exact message. C-VIC works the same way, with icons standing for individual words or ideas; users choose a series of icons in order to form a complete message for speech output. This icon-sequencing, word-by-word construction is what sets these two apart as systems where the focus is on forming messages through ordered icon selections. Other systems often emphasize different access methods or rely more on pre-set phrases or larger phrase banks rather than building sentences strictly by sequencing individual icons, so they don’t embody the same emphasis on icon-by-icon message construction.
