PinchPan: Investigating Children's Collaboration in Cross-Device Interaction

Cross-device interaction provides new and interesting ways of interacting with technology as people have access to a growing number of mobile devices. In different social situations with more people, such cross-device interaction also enables different kinds of collaboration through the devices. In this paper, we explore collaboration and interaction between children during cross-device image exploration. We developed a collocated cross-device application called PinchPan that enables photo exploration and panning through pinching. We studied PinchPan with 22 children who used it in pairs to find different characters in various images. We found that the children adopted a number of different approaches for collaboration in crossdevice interaction, and that panning constitutes a challenge for the image exploration.
