Tangible user interfaces (TUIs) embed computer technology in graspable objects. This study assessed the potential of Topobo, a construction toy with programmable movement, to support social interaction in children with Autistic Spectrum Conditions (ASC). Groups of either typically developing (TD) children or those with ASC had group play sessions with Topobo and with LEGO. We recorded the extent and sequence of different categories of play during these sessions. For both participant groups, there were more social forms of play with Topobo than with LEGO. More solitary play occurred for LEGO and more parallel play occurred with Topobo. Topobo was also associated with more time in onlooker and cooperative play in TD. Finally, we observed differences in play sequences between TD and ASC children, and discuss how different play materials might produce specific patterns of play in these two groups.

Based on ten years' experience developing interactive camera/projector systems for public science and culture exhibits, we define a distinct form of augmented reality focused on social interaction: social immersive media. Our work abandons GUI metaphors and builds on the language of cinema, casting users as actors within simulated narrative models. We articulate philosophical goals, design principles, and interaction techniques that create strong emotional responses and social engagement through visceral interaction. We describe approaches to clearly communicate cultural and scientific ideas through the medium. And we demonstrate how practitioners can design interactions that promote specific social behaviors in users.

We interviewed and observed families in their homes to understand how they communicate across generations and across distances. The phone is still the most common way for keeping children in touch with distant relatives. However, many children can't talk on the phone by themselves until 7 or 8 years old. This paper examines the challenges children have with phone conversations, and looks at how families are currently working around these issues. These findings can help inform the design of future family communications technologies.
