Setwise Comparison: Consistent, Scalable, Continuum Labels for Computer Vision Mining Human Behaviors / Sarkar, Advait / Morrison, Cecily / Dorn, Jonas F. / Bedi, Rishi / Steinheimer, Saskia / Boisvert, Jacques / Burggraaff, Jessica / D'Souza, Marcus / Kontschieder, Peter / Bulò, Samuel Rota / Walsh, Lorcan / Kamm, Christian P. / Zaykov, Yordan / Sellen, Abigail / Lindley, Siân Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.261-271

Summary: A growing number of domains, including affect recognition and movement analysis, require a single, real number ground truth label capturing some property of a video clip. We term this the provision of continuum labels. Unfortunately, there is often an uncacceptable trade-off between label consistency and the efficiency of the labelling process with current tools. We present a novel interaction technique, setwise comparison, which leverages the intrinsic human capability for consistent relative judgements and the TrueSkill algorithm to solve this problem. We describe SorTable, a system demonstrating this technique. We conducted a real-world study where clinicians labelled videos of patients with multiple sclerosis for the ASSESS MS computer vision system. In assessing the efficiency-consistency trade-off of setwise versus pairwise comparison, we demonstrated that not only is setwise comparison more efficient, but it also elicits more consistent labels. We further consider how our findings relate to the interactive machine learning literature.

Collaborating with computer vision systems: an exploration of audio feedback Sound / Morrison, Cecily / Smyth, Neil / Corish, Robert / O'Hara, Kenton / Sellen, Abigail Proceedings of DIS'14: Designing Interactive Systems 2014-06-21 v.1 p.229-238

Summary: Computer visions (CV) systems are increasingly finding new roles in domains such as healthcare. These collaborative settings are a new challenge for CV systems, requiring the design of appropriate interaction paradigms. The provision of feedback, particularly of what the CV system can 'see,' is a key aspect, and may not always be possible to present visually. We explore the design space for audio feedback for a scenario of interest, the clinical assessment of Multiple Sclerosis using a CV system. We then present a mixed-methods experimental study aimed at providing some first insights into the challenges and opportunities of designing audio feedback of this kind. Specifically, we compare audio feedback that differentiates which body parts the CV system can see to audio feedback that is undifferentiated. The findings reveal that it is not enough to simply convey that something might be out of view of the camera as what the camera can 'see' depends on the specific configuration of participants and the peculiarities of the skeleton inference algorithms. The results highlight the importance of providing feedback which more naturally conveys spatial information in developing CV systems for collaborative use.

Place-onas: shared resource for designing body tracking applications Works-in-progress / Morrison, Cecily / Corish, Robert / Sellen, Abigail J. Proceedings of ACM CHI 2014 Conference on Human Factors in Computing Systems 2014-04-26 v.2 p.1861-1866

ACM Digital Library Link

Summary: Developments in computer vision technology have led to a plethora of new body tracking applications. These applications share a challenge in accounting for characteristics of the specific places in which they are intended to be used. We present the concept of Place-onas, representations of "typical" places, as a shared resource to support multidisciplinary team discussions during the development of body tracking applications. We present an example Place-ona drawn from ASSESS MS, a computer vision application that supports the clinical assessment of Multiple Sclerosis. We describe its usage, drawing out how it supported design work, and conclude with a discussion of future work.

Towards Understanding How Humans Teach Robots Short Research Papers / Kaochar, Tasneem / Peralta, Raquel Torres / Morrison, Clayton T. / Fasel, Ian R. / Walsh, Thomas J. / Cohen, Paul R. Proceedings of the 2011 Conference on User Modeling, Adaptation and Personalization 2011-07-11 p.347-352

Summary: Our goal is to develop methods for non-experts to teach complex behaviors to autonomous agents (such as robots) by accommodating "natural" forms of human teaching. We built a prototype interface allowing humans to teach a simulated robot a complex task using several techniques and report the results of 44 human participants using this interface. We found that teaching styles varied considerably but can be roughly categorized based on the types of interaction, patterns of testing, and general organization of the lessons given by the teacher. Our study contributes to a better understanding of human teaching patterns and makes specific recommendations for future human-robot interaction systems.

Hospital user research using new media arts / Morrison, Cecily / Blackwell, Alan F. Proceedings of the HCI'09 Conference on People and Computers XXIII 2009-09-01 p.345-353

Keywords: intensive care, mobile devices, new media arts

ACM Digital Library Link

Summary: This paper presents a comparative analysis of group interaction around two display types, shared and individual, using a 'new media' arts application as a way to explore the physical technology setup for an intensive care unit in a hospital. We propose this method for laboratory settings when the research questions derive from socially complex environments, but real-world interventions are not possible. While users solve an 'interaction problem' that is posed through the 'new media' arts application for their own expressive purposes, researchers can analyse and collate the results to understand the solution space. We present a study with the bodyPaint application to address a design issue that we discovered when assessing the merits of an electronic patient record system.

Intentional affect: an alternative notion of affective interaction with a machine / Afzal, Shazia / Morrison, Cecily / Robinson, Peter Proceedings of the HCI'09 Conference on People and Computers XXIII 2009-09-01 p.370-374

Keywords: affective computing, computer-assisted learning, emotion recognition

ACM Digital Library Link

Summary: Affective Computing envisages truly effective human-machine interactions as being affect-sensitive. The field is both motivated and influenced by an understanding of emotion in an environment, that of person to person, that differs from its eventual application, person to machine. Analysing data obtained in a potential application environment -- computer-assisted learning -- we highlight the limitations of such an understanding and propose an alternative stance to affect, that of intentional affective interaction.

Co-located group interaction design Design theater / Morrison, Cecily / Blackwell, Alan F. Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems 2008-04-05 v.2 p.2587-2590

ACM Digital Library Link

Summary: This design theatre experience explores the use of choreographic improvisation exercises to reflect on the structures of interaction in a mobile, co-located group. The design technique is motivated by studies of clinical ward rounds, and applies analytic models from Kendon, Garfinkel and Hutchins.

Interaction Manifolds: Theory from Experiments Posters / Morrison, Cecily / Blackwell, Alan Proceedings of the HCI'07 Conference on People and Computers XXI 2007-09-03 v.2 p.43

Summary: This poster builds on comparative ethnographic work of a multi-disciplinary medical team using a paper-based and a computer-based patient record system. It describes the design and preliminary results of an experiment aimed to help articulate an analytical construct that would describe the tradeoffs between a technological setup and a group's ability to negotiate an interaction among themselves.

Interaction Manifolds: Understanding Behaviour Around a Shareable Interface Doctoral Consortium / Morrison, Cecily Proceedings of the HCI'07 Conference on People and Computers XXI 2007-09-03 v.2 p.74

Summary: This poster presents a suggestion for how ethnography of shareable interfaces might be used to inform subsequent design decisions by creating an analytical construct that we name the interaction manifold. We first describe and summarize results of our research to date in a medical intensive care unit. We then propose why and how an analytic construct might prove useful for design of shareable interfaces.
