Interface Design

Improving the Design and Accessibility of AAC Systems

Animation

bullet Here is a prezi on potential uses of animation in AAC design based on projects that have been done in my lab

Scanning

bullet Many children with complex communication needs also have concomitant physical disabilities. These individuals may not be able to interact with a computer-based system with their hands. In a visual interface, scanning is a selection method where items in a display are highlighted and individuals who have one volitional movement activate an external device to select an item they see highlighted.
bullet Young children with severe physical impairments have difficulty understanding current methods of scanning.
bullet McCarthy et al., (2006) found that when children are presented with an object that zooms out towards them during a scanning sequence, they were more likely to learn the requirements of the interface with minimal instruction.
bulletAn additional challenge is added when individuals also have visual impairments. When the visual medium cannot be used, items are not highlighted visually, but are announced audibly. Improvements in technology now allow for a variety of animated graphics and sound cues to play within aided AAC displays.
bullet Scanning within visual scenes using a variety of animated and auditory cues is a current focus of research in the lab.
