In a spring article in the UAB Magazine, Dr. Biasini talked about the benefits of computer based interventions like FaceSay, and the encouraging gains seen in the study. 

"Also, the computer tasks performed by children in the study were brief in comparison to the time that might have been spent in social groups to achieve the same gains—we saw benefits that might have taken months to achieve in social groups."
-- UAB Magazine, Spring 2008

I hope FaceSay can be used as an "amplifier"/"accellerator" for group and person to person social work of every sort.  For example, I would bet - er, my hypothesis is - that the Gazing excercises in ABA, the "Thinking with the Eyes" sessions in Michele Garcia Winner's "Social Thinking" program and many others might see larger and/or faster gains when done in conjunction w/ FaceSay.
