Graph Drawings: as created by users (or ‘Doing the Future Work’), Helen Purchase, Glasgow

Here’s an upcoming seminar at 2pm in Robert Recorde room, Thursday May 1st.

Much effort has been spent on designing algorithms for the automatic layout of graphs. Typically, the worth of these algorithms has been determined by their computational efficiency and by the extent to which the graph drawings they produce conform to pre-defined “aesthetics” (for example, minimising the number of edge crosses and edge bends, or maximising symmetry).

Prior experimental work has focussed on the extent to which the layout of a graph drawing assists with the comprehension of the embodied relational information. This seminar presents an alternate approach to determining the relative worth of graph layout aesthetics, based on how users create their own graph drawings. The seminar will present the results of both the published research experiments, as well as two follow-up studies.

Dr Helen Purchase is Senior Lecturer in the School of Computing Science at the University of Glasgow. She has worked in the area of empirical studies of graph layout for several years, and also has research interests in visual aesthetics, task-based empirical design, collaborative learning in higher education, and sketch tools for design. She has recently written a book on Empirical methods for HCI research.

Organiser: Mark W. Jones, Swansea
Programme: Graduate School 2014
Parking: Contact me with your car make, colour and registration number to reserve a space in an onsite pay and display car park just inside the entrance (you still have to pay). Alternatively, the light grey car park on this link is usually free out of term time, and a short walk from the university. It is accessed by turning right into Brynmill Lane, and going right around the roundabout to get back to the Mumbles Road, but on the correct side to access it. You know its free if there is nobody there to take money off you (otherwise £3.50 for the day).
Reserved spaces in the onsite pay and display have been confirmed for, Majid Mirmehdi, Ralph Martin, David Marshall, Jonathan Slade, David Pickup, Kurt Debattista. For others requiring spaces – please use either the light grey car park, or try the pay and display (although space is not guaranteed).
Arrival Information
Sunday arrivals go to Marriott Hotel (Map of exact location) (Bed and breakfast basis paid for, rooms will be reserved in your name – please notify us of any changes in advance to save money). I suggest groups book taxis from Marriott to University (or walk along the beach) as buses in Swansea are too expensive.

Monday arrivals go to Marriott Hotel (Map of exact location) either before lunch or after talks (Bed and breakfast basis paid for, rooms will be reserved in your name – please notify us of any changes in advance to save money). I suggest groups book taxis from Marriott to University (or walk along the beach) as buses in Swansea are too expensive.

Dinner will be in the Grape and Olive. Map of exact location (the entrance is one closest to the Marriott – once inside walk up the 2-3 wooden steps and take the lift to the top floor).

Call for speakers issued (2014-04-01)
We invite talks from PhDs, RAs and academic staff across the four Welsh institutions (and beyond). This provides a great training opportunity for PhD students. Interesting problems, discussions and collaborations arise during these events for all staff and students taking part.

Presentations will be 40 minutes including questions
Kurt Debattista (Warwick), High Fidelity Graphics
Majid Mirmehdi (Bristol)
Tim Weyrich (UCL), Bespoke Computer Graphics Systems for Cultural Heritage Applications

Confirmed RIVIC speakers and participants (as of 2014-06-03)
Presentations will be 15 minutes maximum including questions.
