Understanding 3D Mid-Air Hand Gestures with Interactive Surfaces and Displays: A Systematic Literature Review

Celeste Groenewald, Middlesex

Presentation slides

Celeste Groenewald Profile3D gesture based systems are becoming ubiquitous and there are many mid-air hand gestures that exist for interacting with digital surfaces. There is no well-defined gesture set for 3D mid-air hand gestures which makes it difficult to develop applications that have consistent gestures. To understand what gestures exist we conducted the first comprehensive systematic literature review on mid-air hand gestures following existing research methods. The results of the review identified 65 papers where the mid-air hand gestures supported tasks for selection, navigation, and manipulation. We also classified the gestures according to a gesture classification scheme and identified how these gestures have been empirically evaluated. The results of the review provide a richer understanding of what mid-air hand gestures have been designed, implemented, and evaluated in the literature which can help developers design better user experiences for digital interactive surfaces and displays.

Common ground in collaborative intelligence analysis: an empirical study

Dr Sean Xavier Laurence

Paper

In this talk, I will briefly cover an empirical exploration of how different configurations of collaboration technology affect peoples’ ability to construct and maintain common ground while conducting collaborative intelligence analysis work. Unlike prior studies of collaboration technology that have typically focused on simpler conversational tasks, or ones that involve physical manipulation, the tasks in this study presented focuses on the complex sensemaking and inference involved in intelligence work. The study explores the effects of video communication and shared visual workspace (SVW) on the negotiation of common ground by distributed teams collaborating in real time on intelligence analysis tasks. We theorised that the effect and value of communication cues, visual cues and awareness nuances, is attenuated when communication is mediated via video, more so than it is for shared visual workspace mediated-communication. In this sense, teams utilizing a remote collaborative framework with fewer visual cues might be expected to work harder to maintain common ground, and vice versa.

The experimental study uses a 2×2 factorial, between-subjects design involving two independent variables: presence or absence of Video and SVW. Two-member teams were randomly assigned to one of four experimental media conditions and worked to complete several intelligence analysis tasks involving multiple, complex intelligence artefacts. Teams with access to the shared visual workspace could view their teammates’ eWhiteboards. Our results demonstrate a significant effect for the shared visual workspace: the effort of conversational grounding is reduced in the cases where SVW is available. However, there were no main effects for video and no interaction between the two variables. Also, we found that the “conversational grounding effort” required tended to decrease over the course of the task.

Towards an Approach for Analysing External Representations Created During Sensemaking Using Generative Grammar

Efeosasere Okoro and Simon Attfield (presenting)

Presentation slides

Defe_okorouring sensemaking, users often create external representations to help them make sense of what they know, and what they need to know. In doing so, they necessarily adopt or construct some form of representational language using the tools at hand. By describing such languages implicit in representations we believe that we are better able to describe and differentiate what users do and better able to describe and differentiate interfaces that might support them. Drawing on approaches to the analysis of language, and in particular, Mann and Thompson’s Rhetorical Structure Theory, we analyse the representations that users create to expose their underlying ‘visual grammar’. We do this in the context of a user study involving evidential reasoning. Participants were asked to address an adapted version of the IEEE VAST 2011 mini challenge 3 (interpret a potential terrorist plot implicit in a set of news reports). We show  how our approach enables the unpacking of  heterogeneous and embedded nature of user-generated representations and allows us to show how  visual grammars can evolve and become more complex over time in response to evolving sensemaking needs.

Rethinking Decision Making in Complex Work Settings: Beyond Human Cognition to the Social Landscape

Nallini Selvaraj (presenting) and Bob Fields

Presentation slides

Nallini-smallThis paper presents a fusion of ideas across disciplines to study and conceptualize decision making. Typically, decision making is approached as a cognitive process. Nevertheless, there is a growing shift in perception towards decision making as more than a cerebral activity to one being situated, embedded and embodied in the social landscape of work activities. Research addressing these aspects is still in its infancy and more work is required to develop the notions. The research presented in here makes a theoretical contribution to this shift. Taking a Computer Supported Cooperative Work (CSCW) perspective, this paper explores how decision making is articulated in the cooperative arrangement of a complex work setting. In the process, it explicates the situated, embedded and embodied nature of decision making. The paper reflects on conventional notions of decision making and demonstrates its differentiated nature during every day work performance in a real-world complex work setting.

IDC seminar – Enabling Provenance on the Web: Standardization and Research Questions

Professor Luc Moreau,

Head of the Web and Internet Science group (WAIS),

Department of Electronics and Computer Science (ECS), University of Southampton.

luc_smallProvenance is a record that describes the people, institutions, entities, and activities, involved in producing, influencing, or delivering a piece of data or a thing in the world.

Some 10 years after beginning research on the topic of provenance, I co-chaired the provenance working group at the World Wide Web Consortium. The working group published the PROV standard for provenance in 2013.

In this talk, I will present some use cases for provenance, the PROV standard and some flagship examples of adoption. I will then move on to our current research area aiming to exploit provenance, in the context of the Sociam, SmartSociety, ORCHID, EBook projects. Doing so, I will present techniques to deal with large scale provenance, to build predictive models based on provenance, and to analyse
provenance. I will also discuss how provenance can help with reproducibility, in the context of scientific workflows developed for qualitative analysis in social sciences.

IDC seminar on Co-design by Marianne Markowski (2 short talks)

Dr. Marianne Markowski

Marianne_Markowski2Short talk 1: Co-design, collaborative design or participatory design?

My short talk explores the different interpretations of the word co-design and how it can be understood in different contexts. The perspectives range from HCI, systems design, participatory design to innovative and transformative design perspectives. I further offer a view on the applicability of co-design from a UX practitioner perspective  and my personal definition of co-design, which I developed as a researcher researching with older people.

Short talk 2: Cross-disciplinary views of affective experiences through research skills development

This short talk constitutes a work-in-progress report of our activities in knowledge and skills development when examining affective experiences in online and offlinecultural encounters. The presentation will engage with the different understandings of disciplinary viewpoints around the topic and argue that ‘affective experiences’ are understood and researched in very diverse ways.

Bio

Marianne Markowski has recently completed her PhD studies into designing online social interaction for and with older people. Her practice-based investigation looked at design processes as well as creative design practice (e.g. Teletalker prototype).

Creativity is an inspiration that many people have and always want more – but it is a complex and multifaceted phenomenon. In this talk I will briefly cover some design principles for creativity support tools as well as perspectives on creative interaction. I will focus on user interfaces for creative writing Creative writing is often used as a pedagogical tool to increase literacy. It can also be used to build positive relationships and encourage dialogue across diverse communities. Creative writing gives a voice to marginal groups in society, helping them to tell their stories. In this sense, new tools for creative writers can be used to support community-based writing projects and encourage people from all backgrounds to find their voice and tell their unique stories. But we also believe that creative writing can be used not only for the mental well-being of underserved populations but as a way to empower people to tell their unique stories and thereby increase society’s awareness of their situations and challenges.
