    1. Targeting Technology for Autistic Spectrum DisorderPatrice L. (Tamar) Weiss, Ph.D, OTDept. of Occupational TherapyFaculty of Social Welfare & Health SciencesUniversity of Haifatamar@research.haifa.ac.il

    2. Virtual Reality Applying interactive simulations created with computer hardware and software to present users with opportunities to engage in environments that appear and feel similar to real world objects and events

    3. Virtual Reality Continuum HighTech Low Tech Cost Complexity Presence

    4. User – Location Plane Examples StreetCrossing for ASD Virtual Classroom for ADHD IREX Meal-Maker for CP 4 4

    5. Functional Virtual Environments Desktop System: Street crossing • 6 children, 9-16 years, low functioning ASD used desktop VR street crossing intervention program (ten 30 min sessions); 6 children with ASD as controls. • All children in VR group improved in task while operating the VE. • all succeeded in advancing from initial baseline performance to their final baseline significantly • number of accidents decreased significantly • transfer of skills: 3/6 children achieved greater proficiency in the protected real street environment occurred Josman, N., Milika Ben-Chaim, H., Friedrich, S. and Weiss, P.L. Effectiveness of virtual reality for teaching street-crossing skills to children and adolescents with autism. International Journal of Disability and Human Development. 7: 49-56, 2008. Bart, O., Katz, N., Weiss P.L., & Josman, N. Street crossing by typically developed children in real and virtual environments. OTJR: Occupation, Participation and Health, 28: 89-97, 2008. New VE

    6. Functional Virtual Environments Video Capture Systems: IREX vs EyeToy Virtual Meal Maker: IREX clip 7 years, mainstream school in the first grade, has mild right hemiparesis

    7. Functional Virtual Environments Video Capture Systems: IREX vs EyeToy Using EyeToy with and without adaptation

    8. Functional Virtual Environments Virtual Classroom using a Head Mounted Display Virtual classroom Heads Rizzo et al., University of Southern California Pollak, Y. Weiss, P.

DiamondTouch Interactive Table • Mitsubishi Electronic Research Lab (MERL) • Large horizontal interactive surface • Table-top interaction modality • Operated through PC using Flash programming • Images are top projected Gal, E., Bauminger, N., Goren-Bar, D., Pianesi, F., Stock,O., Zancanaro, M. and Weiss, P.L. Enhancing social communication of children with high functioning autism through a co-located interface. Artificial Intelligence & Society, 24:75–84, 2009.

    13. Story Table • Interface to support pairs of children in the activity of collaborative storytelling • Implements “Enforced Collaboration” paradigm Story characters Lady bugs to hold audio snippets Alternate story backgrounds Voice recording Story sequence

    14. Story Table

    15. Story Table: Initial Study • SAMPLE • 3 pairs of boy with high functioning ASD, 8-11 years • OUTCOME MEASURES • Behavioral Checklist (based on Bauminger, Aviezer & Rogers, 2004) • positive social interactions (e.g., look at peer with positive affect) • negative social interactions (e.g., ignoring action of peer) • autistic behaviors (e.g., perseveration) • Analysis of language usage in the interactions and in the narrations

    16. Story Table: Initial Study Pre- and Post-tests MarbleWorks Free structure play construction game Link to ST intervention video clip Low-Tech ST scenarios with cardboard figures Link to 1 min video clip

    17. Story Table: Initial Study • Comparison of Pre and Post outcomes • increase in key positive social interactions • decrease in negative interactions • increase in narrative and play ability

    18. Collaborative Puzzle Game: Options for non verbal children

    19. PlayCubes: Individual or Collaboration - DCD Real-time Interaction Real-time 3D Modeling Bi-directional Interface

    20. PlayCubes: Individual or Collaboration - DCD

    21. PlayCubes: Individual or Collaboration - DCD Quantitative tracking of the similarity scores during the construction process Similarity versus time during the construction of the airplane and slide apparatus Airplane Slide

    26. User – Location Plane 27

    27. Second Life an Internet-based virtual world launched in 2003 by Linden’s Lab http://lindenlab.com). • “Residents” inhabit virtual worlds and interact via avatars • Users participate in individual and group activities, and to create and trade items and services using Linden dollars • By the end of March 2008, 13 million registered accounts. About 38,000 residents are logged on to Second Life at any particular moment. • number of medical & health educational projects: • Nutrition Game • Occupational Therapy at the Virtual Neurological Education Centre • Brigadoon designed for people with Asperger’s syndrome. Brigadoon - a controlled environment where users are encouraged to feel comfortable and learn socialization skills at their own pace.

    28. Balancing Collaboration Technologies: Assets and Limitations for ASD Bane? • technical complexity • cost • non-real context • Isolation Boon? • Motivation / enjoyment • Initiative / independence • self actualization • Challenge for caregiver • Bottom Line • effectiveness? • transfer?
