- The possibilities of panoramic video are based on the capabilities of high-resolution digital video streams and higher bandwidth's opportunities to broadcast, stream and transfer large content across platforms. With these opportunities also come challenges such as how to focus on sub-parts of the video stream and interact with the content shown on a large screen. In this paper, we present studies of two different interaction modes with a large-scale panoramic video for live experiences; we focus on interactional challenges and explore if it is (1) possible to develop new interactional methods/ways of approaching this type of high-resolution content and (2) feasible for users to interact with the content in these new ways. We developed prototypes for two different interaction modes: an individual system on a mobile device, either a tablet or a mobile phone, for interacting with the content on the same and a non-touch gesture-based system for the home or small group interaction. We present pilot studies where we explore the possibilities and challenges with these two interaction modes for panoramic content.

- Interactive mobile technologies have become part of audience experiences of live performances in terms of both general media sharing and specific (sometimes official) extra content. At the same time, high bandwidth affords streaming of live events to mobile devices. We take advantage of these technologies in our high resolution, panoramic image video stream and study a scenario of audience members viewing the very same live event they are watching on a tablet. The video stream on the tablet is navigational and enables audience members to pan and zoom in the real-time video feed. We studied audience interaction and impressions in three performances of a dance and music show and found distinct uses of the second screen video stream. We emphasize that despite initial reluctance, the observed utilization of the technology opened up for new potential practices. Our study shows how working with perceived conflict in technology can still open up design space for interactive technologies.

Konferensbidrag (refereegranskat)abstract
- We explore the use of a live video broadcast system by a group of collaborating amateur camera operators to film an event on networked cameraphones. Using a detailed interaction analysis of their physical interactions and orientations to the work of others, we examine their choice of camera angles and positions in their filming as they attempt to provide interesting visual content and a coherent narrative. Our findings illustrate how users adapt their behaviour as co-ordination problems occur by drawing from a set of everyday visual practices (‘amateur vision’). The findings also show how the specifically temporal aspect of live video requires extended attention on its production, and that this is at odds with the ‘recreational orientation’ of amateur film crews who simultaneously participate in events for their own enjoyment and film them on behalf of other viewers. Implications for the design of collaborative live broadcast media are made, focusing on approaches to interaction design that augment users’ visual practices and allow users to look on behalf of others while experiencing places and events themselves.

Going Live : Collaborative Video Production After Television
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis explores social and creative practices that emerge with new mobile video technology. The work frames a design space that spans across both the social and technical domains. It associates emerging collaborative practices online with new means for producing and broadcasting media in real time, over mobile networks and using low-cost consumer technology just as these technologies are becoming widely available in the world. As a premise, we sketch a scenario where groups of non-professional users, enabled by new technology available in their mobile phones, produce live media collaboratively. We use detailed ethnographic inquiries into the practices of expert media producers to inform design and spur innovation of new technology. Over the course of the design research process, we have designed and developed two functional prototype systems and produced a number of theoretical contributions to the understanding of the collaborative mobile video space.

Konferensbidrag (refereegranskat)abstract
- In this paper we explore the production of streaming media that involves live and recorded content. To examine this, we report on how the production practices and process are conducted through an empirical study of the production of live television, involving the use of live and non-live media under highly time critical conditions. In explaining how this process is managed both as an individual and collective activity, we develop the concept of temporal hybridity to explain the properties of these kinds of production system and show how temporally separated media are used, understood and coordinated. Our analysis is examined in the light of recent developments in computing technology and we present some design implications to support amateur video production.

Konferensbidrag (refereegranskat)abstract
- Mobile broadcasting services, allowing people to stream live video from their cameraphones to viewers online, are becoming widely used as tools for user-generated content. The next generation of these services enables collaboration in teams of camera operators and a director producing an edited broadcast. This paper contributes to this research ...area by exploring the possibility for the director to join the camera team on location, performing mixing and broadcasting on a mobile device. The Mobile Vision Mixer prototype embodies a technical solution for connecting four camera streams and displaying them in a mixer interface for the director to select from, under the bandwidth constraints of mobile networks. Based on field trials with amateur users, we discuss technical challenges as well as advantages of enabling the director to be present on location, in visual proximity of the camera team.

Konferensbidrag (refereegranskat)abstract
- Pro-Am live video producers broadcast events on a regular basis. They are here selected for an ethnographic study since their continuous content generation can teach us something of what it takes for amateurs, who currently struggle with mastering the video medium, to become proficient producers. We learn from media theory that Pro- Ams are distinguished from professionals in terms of inherent skills and identities, and have therefore focused on these characteristics. We add to this research by showing on-going challenges that the former face in their production, i.e. how their learning practices, such as learning through instructions, are situated and related to particular settings. Learning and development of skills were done as organizations, rather than as individuals. Furthermore, the recurrent nature of both events and broadcasts appears to be an important condition for establishing the terms needed to carry out a production, and to learn the skills of a producer. This understanding may explain in part why accounts in previous research, of single users struggling with the affordances of live video, point to such difficulties in mastering the medium. The findings guide design to better support activities contiguous with the set-up of the production, rather than the broadcast per se.

Konferensbidrag (refereegranskat)abstract
- A new type of social medium, which allows users to broadcast live video from mobile devices to websites on the internet, is becoming increasingly popular. We provide a qualitative content analysis of a sample from four such services. The analysis specifically focuses on the topics presented, camerawork, and coordination, in order to investigate the possibilities and barriers to wider adoption of this new social medium. Although the services are growing in numbers of users, the study reveals an immature application area. People struggle to find interesting topics to broadcast and to manage the camera in a way that presents them in an appealing form. But there are also examples of topics such as artistic performances and tours, as well as ways to conduct live transitions and coordination, that point to a more medium-specific way of using these services. The results indicate that providing the opportunity to broadcast live video is not enough, and that there is now a need to design for amateurs' appropriation of camera handling techniques.
