Main Article Content
Abstract
Augmentative and Alternative Communication (AAC) systems support individuals
with complex communication needs. This review article examines factors influencing
the design of grid displays in AAC systems to enhance symbol searching accuracy
and reduce latency. Four key areas are identified: the organization of symbols, color
cues, visual crowding, and symbol location. Effective symbol organization, such as
semantic-syntactic and schematic displays, can facilitate efficient communication,
while color cues may improve visual attention and memory recall. Managing visual
crowding and strategically placing symbols based on visual field biases and motor
control abilities are also crucial. By optimizing these elements, speech-language
pathologists can develop AAC displays that improve user communication outcomes.
The findings provide guidelines for designing user-centered AAC systems tailored
to individual cognitive, motor, and sensory needs.
