Live mobile collaboration for video production: design, guidelines, and requirements
Traditional cameras and video equipment are gradually losing the race with smart phones and small mobile devices that allow video, photo, and audio capturing on the go. Users are now quickly creating movies and taking photos whenever and wherever they go, particularly at concerts and live events (e.g., shows, sport events). Still, in-situ media capturing with such devices poses constraints to any user, especially amateur ones. In this paper, we present the design and evaluation of a mobile video capture suite that allows for cooperative ad hoc production. Our system relies on ad hoc in-situ collaboration offering users the ability to switch between streams and cooperate with each other in order to capture better media with mobile devices. Our main contribution is the real-time awareness that users gain on media capturing endeavors around them and the possibility to collect that data for personal use once the event is over. This contribution is further emphasized by the geo-referenced cues that support the overall user interface and the management of the different media streams. As a secondary contribution, we report on lessons and design guidelines that emerged and apply to in-situ design of rich video collaborative experiences and with the elicitation of functional and usability requirements related to privacy, social connections, and gamification.
