Results

No quantifiable impact on children's behaviors or school performance.

One child especially enjoyed using the tablet in conjunction with the teacher.

A smaller device could be a better option:

“Change the size of the tablet to one possibly a little bigger than a smart phone so staff can put it in a pocket if need to respond to student with two hands free.”

Other Findings

Future Work•More systematic comparison

between pen & paper method and the application

•Inclusion of wireless biosensors

•Infrastructure to share and visualize data

•Mobile tool to easily capture and annotate challenging behaviors

•Application available online

•Potential benefits

1) Connecting stakeholders

2) Data-driven characterization of ASD

3) More personalized behavioral interventions
