R3: Motion to improve AAC user interface displays

Team Leaders: Janice Light, Krista Wilkinson
AAC Consumer Team: David Chapple, Musar

Challenge and Background Information

  • Most technology displays, including AAC displays, are not research-based:
    • they impose significant visual cognitive processing demands
    • they create distractions
    • they impede communication performance
  • The use of eye tracking research technologies can help investigate visual attention to AAC displays in order to improve design
    • For example, you can measure:
      • Latency, frequency, duration, sequence of visual fixations
  • RERC on AAC (2014-20) investigated effects of display characteristics on visual cognitive processing of individuals with complex needs (e.g., color, layout, navigation bar, etc.)
    • The resulting research-based specification were disseminated to manufacturers & service providers 

Goals


The new RERC on AAC will investigate the effects of targeted motion in AAC displays to increase visual attention & learning. Expected outcomes include

  • Scientifically-based design specifications for using motion in AAC displays
  • Maximize visual attention to key components
  • Maximize learning of new symbols
    • Picture symbols
    • Written text
  • Enhance communication performance
