Tidskriftsartikel (refereegranskat)abstract
- 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.

Amateur vision and recreational orientation : Creating live video together
- 2012

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.

Instant broadcasting system : mobile collaborative live video mixing
- 2009
-
Ingår i: SIGGRAPH ASIA '09. - New York : ACM. - 9781605588780 ; , s. 73-73
-
Konferensbidrag (refereegranskat)abstract
- With Instant Broadcasting System, people can collaboratively produce, edit, and broadcast live video using only mobile phones, a laptop computer, and available mobile networks. In this demonstration, it is used as a VJ system that supports visitor-generated video, flexible content selection, a communication back channel, and real-time loop editing. These features move the system beyond previous webcam-based VJ concepts.

Konferensbidrag (refereegranskat)abstract
- We report on design research investigating a possible combination of mobile collaborative live video production and VJing. In an attempt to better understand future forms of collaborative live media production, we study how VJs produce and mix visuals live. In the practice of producing visuals through interaction with both music and visitors, VJing embodies interesting properties that could inform the design of emerging mobile services. As a first step to examine a generation of new applications, we tease out some characteristics of VJ production and live performance. We then decide on the requirements both for how visitors could capture and transmit live video using their mobile phones and how this new medium could be integrated within VJ aesthetics and interaction. Finally, we present the SwarmCam application, which has been implemented to investigate these requirements.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- We analyze how VJs produce visuals to support DJs in dark and noisy club environments, enhancing the overall experience. We suggest that mobile technologies could improve the interaction between the audience and the VJ. As a first step to the generation of new applications, we tease out some characteristics of VJ production and live performance, which might influence the design of such technologies. We specifically focus on the ways in which VJs interact with the audience and the computer interfaces, as well as how they orient towards specific aesthetical ideals.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents a study of professional live TV production, investigating the work and interactions between distributed camera operators and a vision mixer during an ice hockey game. Using interview and video data, we discuss the vision mixer's and camera operators' individual assignments, showing the role of video as both a topic and resource in their collaboration. Our findings are applied in a design-oriented examination into the interactive user experience of TV, and inform the development of mobile collaborative tools to support amateur live video production.

Ingår i: CHI '10 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems. - New York, NY, USA : Association for Computing Machinery (ACM). - 9781605589299 ; , s. 1495-1504
-
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.

The Mobile Vision Mixer : A mobile network based live video broadcasting system in your mobile phone
- 2012

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.
