Personal and Ubiquitous Computing journal, Theme issue on Video interaction – Making broadcasting a successful social medium
Paper submission deadline: November 11, 2011


Recent years have seen a range of new services in the online video space, enabled by widespread broadband access and inexpensive capture devices in digital cameras and mobile phones. Video traffic has quickly become the bulk of data communication on the Internet, and content is increasingly transmitted live. A new type of social media services, which make it possible to capture live video and share it in real time to Internet, is growing in popularity. The services are innovative in their combination of mobile technology and live video, and have been praised as the next generation of online video. But these new technologies and practices also present new interactional, experiential and production-related challenges. Among other things, people struggle to find interesting topics to broadcast, to produce video in real-time, and to manage the camera in a way that presents them in an appealing form. As for the viewing experience, it is hard to find live broadcasts of interest. Broadcasts often receive minimal audiences, although the numbers increase with integration into other social media platforms.

In addition to live streaming systems, other mobile applications and services are now allowing users to capture their environment and share them with wider user groups. People have found social applications for diverse media types such as text (microblogs like Twitter, chats etc); photography (e.g. Flickr); audio (e.g. Myspace); and video files (e.g. Youtube), many of them with simple mobile interfaces for uploading just-captured content and sharing views of current experiences with wide audiences. This ability to post content for later consumption and viral spreading is perhaps one of the most compelling ways to share an experience. It is still an open question whether mobile live video will become as successful form of social media as these.

Challenges for the wider appropriation of new mobile services involving live video are still largely unexplored. This special issue invites work exploring topics relevant to services and experiences in the mobile live video space.

Topics of interest include, but are not limited to:
	• Mobile live video
	• Mobile broadcasting services and applications
	• Video as social medium
	• Experience sharing
	• User experience in video-based systems
	• Designing for variability in use practices and use contexts
	• Video literacy
	• Collaboration, co-ordination and awareness
	• Hybrid formats (use of available sensors on mobile device together with video)
	• Interaction with live video
	• Privacy
