Optimizing AAC display design for individuals with developmental or acquired disabilities: Contributions of eye-tracking research. Presentation at the Annual Conference of the American Speech-Language Hearing Association (ASHA), Los Angeles, CA.
Abstract: Aided augmentative and alternative communication (AAC) often uses visual symbols/displays. If these displays are confusing or difficult to navigate, AAC interventions may be rendered less effective. This session presents research using automated eye tracking technologies that evaluated visual processing of AAC displays by individuals with developmental or acquired disabilities.
Optimizing AAC displays is essential for creating future designs that adhere to the needs of an individual with severe communication deficits. Creating visually-appealing AAC designs and implementing methods, such as eye-gaze fixation patterns, help researchers understand how these individuals process meaning and extract information presented in AAC displays.
