Online social media services, such as Facebook and Twitter, have set new standards on how people interact with each other online, share their everyday activities, and media services. While current mobile services supporting social interaction are typically primarily for remote communication, similar services can be introduced to co-located social interactions. In such a setting, people and proactive, context sensing mobile devices form a new kind of a socio-digital system where the mobile devices are active participants and can initiate interaction among the devices and people. Physical proximity of the devices becomes a key enabler to advance users' interaction with each other and the supporting mobile services. In this paper, we introduce the concept of Social Devices and its implementation. The Social Devices Platform facilitates autonomously composed cooperative services in co-located devices where the client part is simple and easily deployable to different kinds of devices.
