In mobile collocated interactions, groups of users spontaneously combine their mobile devices to engage in rich shared activities and experiences. Various physical and social contexts of use have been taken into account, such as sharing media content at home.
Pass-Them-Around is a phone-based application that allows a small group of collocated people to share photos using the metaphor of passing paper photos around. The prototype supports ad-hoc photo sharing in different contexts by taking into account the spatial arrangement of users around a table, measured with sensors embedded in their mobile phones.
