The Effects of Animated Feedback on Locating Verbs in a Dynamic Contextual Scene Display on an Augmentative and Alternative Communication Device

Purpose: Technological advances in augmenta- tive and alternative communication (AAC) offer the poten- tial to enhance the communication needs of individuals with severe communication disorders. However, using AAC to express concepts that cannot be easily represented in static line drawings is a significant challenge. Animation of line-drawn action verbs represents a means to enhance the transparency of previous static representations and poten- tially make the representations easier for children to use. Method: A mixed group design with repeated measures was used to test the effect of animation used as feedback in locating and selecting action verbs in a visual scene on a dynamic AAC display. Twenty 3-year-old children without disabilities (10 boys and 10 girls) were quasirandomly as- signed to an animation or no-animation group. Participants' M
