Transcript of Investigating A Virtual Tutor Approach Cape
Paul Herring, Dr Kieron Sheehy

Investigating a ‘virtual tutor’ approach for improving the
communication skills of children with autism
2
Autism and the triad of impairments
Diagnosis and beyond
3
• On average children with autism are diagnosed from about 3 years old (Baron-Cohen, 2008)
• Access to interventions is often delayed until the child enters the education system
• Current research suggests early intervention increases the chances of a positive prognosis in later life (Wetherby & Woods, 2006)
Picture Exchange Communication System (PECS)
4
5
The advantages of PECS
• the communication exchange is easily understood by communicator and communication partner
• the communication is meaningful and highly motivating for the child with autism
• PECS has been shown to promote spontaneous symbol communication
Bondy & Frost, (1995)
Are there any benefits to Computer based teaching
methods?• Improved attention and motivation
6
• curiosity and length of time spent on a subject
• promote spontaneous commenting
• A reduction in echolalia and inappropriate behaviour
Williams et al (2002)
Computer Assisted Picture Exchange (CAPE)
7
• Provide avatar led teaching environment to teach symbol based communication to children with autism
• Allow participants to interact with CAPE using physical symbols as a method of participant input
• Provide an easy to use and engaging environment for children with autism
8
The CAPE prototype interface
9
CAPE user testing
Future Work
• A preliminary study to understand how an avatar’s voice type may influence participant engagement
• A five week study to understand if CAPE can enhance symbol based communication for children with autism
