R1: Video Visual Scene Display (VSD) Intervention

Team Leaders: David McNaughton, Janice Light
AAC Consumer Team: Chris Klein, Tracy Rackensperger


  • Less than 5% of individuals with complex communication needs are employed full time.
  • Less than 10% of adults with severe intellectual or multiple disabilities have access to effective means to participate in community activities.

Past work

RERC on AAC (2014-20) developed a video VSD AAC app that integrates

  • Video models of individuals completing tasks
  • Captured via built-in camera/wireless
  • AAC supports for communication
    • Messages are embedded into videos at key junctures (“hot spots” are created)
  • 100% of participants showed increases in their community participation
Sample video VSD page for use in cafe


The new RERC on AAC will complete a large scale evaluation of video VSD technology under real world conditions. We will identify the key intervention activities which best support increases in successful participation in vocational and community activities by individuals with complex communication needs.
