SACHI at DIS 2014

Jakub Dostal from SACHI and external co-authors published a paper at this year’s DIS conference. The paper was awarded the best paper award, given to the top 1% papers at the conference. This paper is one of the outcomes of a Dagstuhl seminar on Proxemics in Human-Computer Interaction, which Aaron Quigley helped organise and which was attended by several SACHI members.

Dark Patterns in Proxemic Interactions: A Critical Perspective.

Proxemics theory explains peoples’ use of interpersonal distances to mediate their social interactions with others. Within Ubicomp, proxemic interaction researchers argue that people have a similar social understanding of their spatial relations with nearby digital devices, which can be exploited to better facilitate seamless and natural interactions. To do so, both people and devices are tracked to determine their spatial relationships. While interest in proxemic interactions has increased over the last few years, it also has a dark side: knowledge of proxemics may (and likely will) be easily exploited to the detriment of the user. In this paper, we offer a critical perspective on proxemic interactions in the form of dark patterns: ways proxemic interactions can be misused. We discuss a series of these patterns and describe how they apply to these types of interactions. In addition, we identify several root problems that underlie these patterns and discuss potential solutions that could lower their harmfulness.

SACHI Excursion at Isle of May

On the 19th of June, 2014, the group went out on an excursion to the Isle of May, just off the coast of Anstruther. It was the perfect time to visit, with beautiful weather all day long, and with what we were told to be a quarter of a million birds, as it was the middle of the nesting season. That was actually quite believable, as we saw entire cliff faces covered in birds nested as our ferry, the May Princess, toured round the island: there were puffins, seagulls, ducks, swans, terns – and even a few seals. We enjoyed hiking round the island and photographing the birds for close to three hours. The serene environment gave us a wonderful opportunity to step out of our offices/labs into the bright sunshine and taste the wind and sea – and to embrace the wonders of Mother Nature. As we were getting on and off the boat, we also had quite the “in the wild” experience, when the terns, who were nesting in the mini-harbour area, attacked us in droves, dive-bombing us from overhead to warn us off! We ended the day with an unforgettable meal of Fish and Chips from the famous Anstruther Fish Bar, and with smiles and happy memories!

SACHI at PerDis’14: What to See

PerDis 2014 - 1This year Aaron Quigley was the program chair for PerDis’14 the 3rd ACM International Symposium on Pervasive Displays at the University of Copenhagen in Denmark. This year’s symposium extends the two previous successful symposia PerDis’13 in Google, Mountain View, California, USA and PerDis’12 at the University of Minho in Porto, Portugal.

This year we brought together researchers and practitioners from various disciplines with a common interest in the opportunities and challenges raised by the emergence of pervasive display systems as a new communication medium for public and semi-public spaces. The continued emergence of media facades, pervasive displays as art installations, 3D and in-air display, mobile and display networks gives rise to many new innovations and explorations.

Along with his role as program chair and session chair Aaron presented work on CSCT – Computer Supported Cooperative Teaching authored with Adam Buckland. The overall program included 30 papers, 4 posters, 4 demos and 3 videos which have helped lay the foundation for this emerging research community.

May 20th, seminar with Aaron Quigley and Daniel Rough – Practice talks for AVI

Speaker: Aaron Quigley and Daniel Rough, University of St Andrews
Date/Time: 12-1pm May 20, 2014
Location: Jack Cole 1.33a

Title: AwToolkit: Attention-Aware User Interface Widgets
Authors: Juan-Enrique Garrido, Victor M. R. Penichet, Maria-Dolores Lozano, Aaron Quigley, Per Ola Kristensson.

Abstract: Increasing screen real-estate allows for the development of applications where a single user can manage a large amount of data and related tasks through a distributed user inter- face. However, such users can easily become overloaded and become unaware of display changes as they alternate their attention towards different displays. We propose Aw- Toolkit, a novel widget set for developers that supports users in maintaing awareness in multi-display systems. The Aw- Toolkit widgets automatically determine which display a user is looking at and provide users with notifications with different levels of subtlety to make the user aware of any unattended display changes. The toolkit uses four notifica- tion levels (unnoticeable, subtle, intrusive and disruptive), ranging from an almost imperceptible visual change to a clear and visually saliant change. We describe AwToolkit’s six widgets, which have been designed for C# developers, and the design of a user study with an application oriented towards healthcare environments. The evaluation results re- veal a marked increase in user awareness in comparison to the same application implemented without AwToolkit.

Title: An Evaluation of Dasher with a High-Performance Language Model as a Gaze Communication Method
Authors: Daniel Rough, Keith Vertanen, Per Ola Kristensson

Abstract: Dasher is a promising fast assistive gaze communication method. However, previous evaluations of Dasher have been inconclusive. Either the studies have been too short, involved too few partici- pants, suffered from sampling bias, lacked a control condition, used an inappropriate language model, or a combination of the above. To rectify this, we report results from two new evaluations of Dasher carried out using a Tobii P10 assistive eye-tracker machine. We also present a method of modifying Dasher so that it can use a state-of-the-art long-span statistical language model. Our experi- mental results show that compared to a baseline eye-typing method, Dasher resulted in significantly faster entry rates (12.6 wpm versus 6.0 wpm in Experiment 1, and 14.2 wpm versus 7.0 wpm in Exper- iment 2). These faster entry rates were possible while maintaining error rates comparable to the baseline eye-typing method. Partici- pants’ perceived physical demand, mental demand, effort and frus- tration were all significantly lower for Dasher. Finally, participants significantly rated Dasher as being more likeable, requiring less concentration and being more fun.

This seminar is part of our ongoing series from researchers in HCI. See here for our current schedule.

SACHI Logo Contest

SACHI-best-studentEarlier this year we held the SACHI Logo Contest. To decide on the outcome we formed a jury of 10 people, consisting of 5 academic and 5 student members of SACHI. We are pleased to announce that the best student design for our logo contest was submitted by Jason T. Jacques, which you can see to the left. Both the academic and students members of the jury selected Jason’s logo as the best student design.

The logo submitted by Uta Hinrichs, while not eligible for the student prize, was the top ranked entry and has been chosen as the logo to represent SACHI going forward. Congratulations to both Jason and Uta! You can see Uta’s logo options below which we will be adding to our website (once redesigned in the months ahead). We also apologise to both Uta and Jason for reducing their submissions into these blog worthy thumbnails which do neither justice.

May 6th, seminar by Alan Dix: At The Edge

Speaker: Alan Dix, Birmingham University
Date/Time: 2-3pm May 6, 2014
Location: Maths Lecture Theatre B, University of St Andrews

IMG_3488 From buying plane tickets to eGovernment, participation in consumer and civic society is predicated on continuous connectivity and copious computation . And yet for many at the edges of society, the elderly, the poor, the disabled, and those in rural areas, poor access to digital technology makes them more marginalised, potentially cut off from modern citizenship. I spent three and half months last summer walking over a thousand miles around the margins of Wales in order to experience more directly some of the issues facing those on the physical edges of a modern nation, who are often also at the social and economic margins. I will talk about some of the theoretical and practical issues raised; how designing software with constrained resources is more challenging but potentially more rewarding than assuming everyone lives with Silicon Valley levels of connectivity.

Alan is Professor of Computing at University of Birmingham and Senior Researcher at Talis based in Birmingham, but, when not in Birmingham, or elsewhere lives in Tiree a remote island of the west coast of Scotland.

Alan’s career has included mathematical modelling for agricultural crop sprayers, COBOL programming, submarine design and intelligent lighting. However, he is best known for his work in Human Computer Interaction over three decades including his well known HCI textbook and some of the earliest work in formal methods, mobile interaction, and privacy in HCI. He has worked in posts across the university sector as well as a period as founder director of two dotcom companies, aQtive (1998) and vfridge (2000), which, between them, attracted £850,000 of venture capital funding. He currently works part-time for the University of Birmingham and is on the REF Panel for Computer Science. He also works part-time for Talis, which, inter alia, provides the reading list software used at St Andrews.

IMG_3487His interests and research methods remain, as ever, eclectic, from formal methods, to technical creativity and the modelling of regret. At present he is completing a book, TouchIT, about physicality in design, working with musicologists on next generation digital archives, envisioning how learning analytics can inform and maybe transform university teaching, and working in various projects connected with communication and energy use on Tiree and rural communities.

Last year he completed a walk around Wales as an exploration into technical issues ‘at the edge’, the topic of his seminar.

This seminar is part of our ongoing series from researchers in HCI. See here for our current schedule.
