Towards Participatory Video 2.0
要旨

Participatory video (PV) is an established practice for enabling communities to "speak truth to power" and has been widely used by local, national and international Non-Governmental Organizations (NGOs). However, the digital media landscape has changed dramatically since PV became widely accessible with the rise of the camcorder in the 1980s. Current media practices have evolved considerably since, yet PV remains essentially unchanged. We report on an investigation of current PV practices and reflect on these in terms of what the future for PV holds. We conducted interviews with staff at a global humanitarian network who directly and indirectly engage in community story capture; and explore their reflections on the potentials and barriers to PV use. We propose a new vision for PV that draws on current visual media production, consumption and distribution technologies and practices, and propose principles on which PV 2.0, a new generation of Participatory Video can be founded.

Instructional Video Design: Investigating the Impact of Monologue- and Dialogue-style Presentations
要旨

Instructional videos are frequently used in online courses and websites. Such videos may include an instructor delivering a monologue-style presentation, or alternatively, engaging in a dialogue with a student who appears in the video alongside of the instructor. We compared three instructional video designs (N = 77), including monologue and dialogue style presentations. To obtain a comprehensive view of the impact of video design, we used a variety of measures, including eye tracking data, learning gains, self-efficacy, cognitive load, social presence, and interest. Despite eye tracking data showing that participants in speaker-visible conditions spent significantly less time on the domain content, learning and related variables were similar in all three conditions, a result we confirmed with Bayesian statistics that provided substantial evidence for the null model. Altogether, we provide evidence that learning and interest are not enhanced by a dialogue-style presentation or visual presence of the instructor. However, further work is needed to investigate the effect of other domains, speaker persona and saliency, and configuration of the speakers in the instructional video.

On Pause: How Online Instructional Videos are Used to Achieve Practical Tasks
要旨

Instructional videos have become an important site of everyday learning. This paper explores how these videos are used to complete practical tasks, analyzing video-recorded interactions between pairs of users. Users need to repeatedly pause their videos to be able to follow the instructions, and we document how pausing is used to coordinate and interweave watching and doing. We describe four purposes and types of pausing: finding task objects, turning to action, keeping up, and fixing problems. Building on these results, we discuss how video players could better support following instructions, and the role of basic user interface functions in complex tasks involving different forms of engagement with the physical world and with screen-based activity.

Classification of Functional Attention in Video Meetings
要旨

Participants in video meetings have long struggled with asymmetrical attention levels, especially when participants are distributed unevenly. While technological advances offer exciting opportunities to augment remote users' attention, the phenomenological complexity of attention means that to design attention-fostering features we must first understand what aspects of it are functionally meaningful to support. In this paper, we present a functional classification of observable attention for video meetings. The classification was informed by two studies on sense-making and selectiveness of attention in work meetings. It includes categories of attention accessible for technological support, their functions in a meeting process, and meeting-related activities that correspond to these functions. This classification serves as a multi-level representation of attention and informs the design of features aiming to support remote participants' attention in video meetings.

Connecting Distributed Families: Camera Work for Three-party Mobile Video Calls
要旨

Mobile video calling technologies have become a critical link to connect distributed families. However, these technologies have been principally designed for video calling between two parties, whereas family video calls involve young children often comprise three parties, namely a co-present adult (a parent or grandparent) helping with the interaction between the child and another remote adult. We examine how manipulation of phone cameras and management of co-present children is used to stage parent-child interactions. We present results from a video-ethnographic study based on 40 video recordings of video calls between 'left-behind' children and their migrant parents in China. Our analysis reveals a key practice of 'facilitation work', performed by grandparents, as a crucial feature of three-party calls. Facilitation work offers a new concept for HCI's broader conceptualisation of mobile video calling, suggesting revisions that design might take into consideration for triadic interactions in general.
