The increasing rates of diagnosis for Autism Spectrum Disorders (ASDs) have brought unprecedented attention to these conditions. Interventions during childhood can increase the likelihood of independent living later in life, but most adults with ASDs who benefited from early intervention do not live independently. There is a need for novel therapies and interventions that can help children with ASDs develop the social skills necessary to live independently. Since the launch of the iPad, there has been a great deal of excitement in the autism community about multitouch tablets and their possible use in interventions. There are hundreds of apps listed as possibly helping children with ASDs, yet there is little empirical evidence that any of them have positive effects. In this paper we present a study on the use of a set of apps from Open Autism Software at an afterschool program for children with ASDs. The apps are designed to naturally encourage positive social interactions through creative, expressive, and collaborative activities. The study compared activities conducted with the apps to similar activities conducted without the apps. We video recorded the activities, and coded children's behavior. We found that during the study children spoke more sentences, had more verbal interactions, and were more physically engaged with the activities when using the apps. We also found that children made more supportive comments during activities conducted with two of the apps. The results suggest the approach to using apps evaluated in this paper can increase positive social interactions in children with ASDs.

Chronic headaches are one of the top five health problems for young children in the United States, negatively affecting their quality of life and learning opportunities. A clear understanding of children's headache characteristics is crucial for delivering appropriate treatment. However, current data collection methods were designed for adults often resulting in insufficient information. In this paper we present a novel method to help children communicate with health care providers and researchers about their headaches. It augments an existing child-centric method called Draw-and-Tell Conversation, which has already been shown to provide more actionable information from children than standard data collection methods. It does so by enabling children to draw their symptoms on a zoomable drawing application, giving them the ability to provide more details and context than on paper. We present a study conducted with nineteen children aged 7 to 12 suggesting that children provided more information about their headaches when using the zoomable drawing application than when drawing on paper. This study provides a rare example of a mobile device used to enhance face-to-face interactions and contributes evidence of a specific benefit of zoomable user interfaces.
