A Mobile Application for Information Sharing and Collaboration among Colocated People

We present an android mobile application named DIO providing collaboration features, which are specially designed for co-located people to chat, vote, and survey. In addition, to share their personal information effectively and appropriately, DIO supports functions for sharing and exchanging their profiles, favorite photos, musics, videos and documents according to one of the three open levels – public, business and community level. Since DIO is implemented on the top of AllJoyn platform which is an open source IoT platform developed by the AllSeen Alliance, it can be easily extended for communicating with other smart things adopting the same platform.
