Efeosasere Okoro, MSc


In January, Efe Okoro was awarded MSc Research. Efe’s thesis, ‘A study of different representation conventions during investigatory sensemaking’ explores the value of using different kinds of representational conventions for an intelligence analysis task. The study takes a particular interest in narrative, argumentation and freeform representations. Efe found that allowing users to structure information in freeform ways results in lower cognitive load. A post-hoc qualitative analysis resulted in Embedded Representational Structuring Theory (ERST), an approach which uses a finite set of conventions to characterise the structure of free-form user-generated representations.

IDC Students attend TUTOREM 2013

20131106_213358Phong Nguyen, Ashley Wheat and Marianne Markowski recently attended the TwinTide AUtumn Training SchOol 2013: REsearch Methods for Human-Computer Interaction (TUTOREM 2013). The overarching goal of TUTOREM is to improve participants’ understanding of significant research methods commonly or increasingly used in the field of HCI. Such an enhanced understanding will enable them to select and combine appropriate research methods for their specific HCI projects and to contextualise them without unintended impacts on validity. While we recognise the importance of theories that inform the development of research methods, due to the time constraint no session is dedicated to HCI theories. Nevertheless, relevant theoretical frameworks will be addressed in individual sessions of TUTOREM, which consist of lectures, workshops and discussions. In addition, student participants will collaboratively work in small groups on a mini-project with the topic identified by the School’s lecturers.

Presentations at Visweek 2013, Atlanta, Georgia

Dr Rick Walker presented work on “An Extensible Framework for Provenance in Human Terrain Visual Analytics” from the SPSRC-DSTL funded joint project DIVA – Data Intensive Visual Analytics, in collaboration with City University and Loughborough University. The paper describes the use of Qype data as a surrogate for human terrain data, and presents novel interaction techniques such as sandbox for constructing narratives.

Dr. Neesha Kodagoda presented “Using Interactive Visual Reasoning to Support Sense-Making: Implications for Design”, which was supported through the UK Visual Analytics Consortium that has been funded by Her Majesty’s Government and the U.S. Department of Homeland Security.
