Collaborative annotation of real time streams on android-enabled devices
Tao Huang, Geoffrey Q. Fox · 2012
Mobile based collaboration such as image tagging and video annotation has become a research hotspot for both academic groups and the industry. Mobile devices running with Google Android or Apples iOS have almost the same computing and multimedia capabilities as modern computers, which enables conducting regular collaborative activities on them. Moreover their embedded geographic sensors can provide useful auxiliary metadata to help improve the accuracy of several collaboration features such as location annotation and tagging recommendation. In this paper, we firstly analyze recent research on mobile based collaboration and annotation projects, and then we introduce our efforts in expanding a collaborative annotation framework to the mobile platforms, especially the android-enabled devices. A prototype of the mobile extension that supports collaborative annotation on real time data streams especially audiovisual streams is introduced as well as several preliminary performance experiments.
