Abstract:
In the United States, there are an estimated 98,000 people per year killed and $17.1 billion dollars lost due to medical errors. One way to prevent these errors is to have clinical students engage in simulation-based medical education, to help move the learning curve away from the patient. This training often takes place on human-sized android robots, called high-fidelity patient simulators (HFPS), which are capable of conveying human-like physiological cues (e.g., respiration, heart rate). Training with them can include anything from diagnostic skills (e.g., recognizing sepsis, a failure that recently killed 12-year-old Rory Staunton) to procedural skills (e.g., IV insertion) to communication skills (e.g., breaking bad news). HFPS systems allow students a chance to safely make mistakes within a simulation context without harming real patients, with the goal that these skills will ultimately be transferable to real patients.
While simulator use is a step in the right direction toward safer healthcare, one major challenge and critical technology gap is that none of the commercially available HFPS systems exhibit facial expressions, gaze, or realistic mouth movements, despite the vital importance of these cues in helping providers assess and treat patients. This is a critical omission, because almost all areas of health care involve face-to-face interaction, and there is overwhelming evidence that providers who are skilled at decoding communication cues are better healthcare providers – they have improved outcomes, higher compliance, greater safety, higher satisfaction, and they experience fewer malpractice lawsuits. In fact, communication errors are the leading cause of avoidable patient harm in the US: they are the root cause of 70% of sentinel events, 75% of which lead to a patient dying.
In the Robotics, Health, and Communication (RHC) Lab at the University of Notre Dame, we are addressing this problem by leveraging our expertise in android robotics and social signal processing to design and build a new, facially expressive, interactive HFPS system. In this talk, I will discuss our efforts to date, including: in situ observational studies exploring how individuals, teams, and operators interact with existing HFPS technology; design-focused interviews with simulation center directors and educators which future HFPS systems are envisioned; and initial software prototyping efforts incorporating novel facial expression synthesis techniques.

Abstract:
The virtual wall is a simple privacy metaphor for ubiquitous computing environments. By expressing the transparency of a wall and the people to which the wall applies, a user can easily manage privacy policies for sharing their sensed data in a ubiquitous computing system.
While previous research shows that users understand the wall metaphor in a lab setting, the metaphor has not been studied for its practicality in the real world. This talk will describe a smartphone-based experience sampling method study (N=20) to demonstrate that the metaphor is sufficiently expressive to be usable in real-world scenarios. Furthermore, while people’s preferences for location sharing are well understood, our study provides insight into sharing preferences for a multitude of contexts. We find that whom data are shared with is the most important factor for users, reinforcing the walls approach of supporting apply-sets and abstracting away further granularity to provide improved usability.

Dr Apu Kapadia is a Distinguished SICSA Visitor in August 2012. As part of his visit we are organising a pair of masterclasses in running mobile user studies. These masterclasses are open to all SICSA PhD students. Students will be need to be available to attend both masterclasses:

• Thursday 2 August, University of Glasgow
• Thursday 9 August, University of St Andrews

The classes will cover how to design and run a mobile user study using smartphones, and in particularly cover the use of the experience sampling method (ESM), a currently popular methodology for collecting rich data from real-world participants. In the first class, attendees will learn about the methodology and be given a smartphone. Attendees will then carry the smartphone and participate in a small study, and we will cover data analysis in the second class in St Andrews. The organisers have experience in running ESM studies which have looked at mobility, social networking, security and privacy, but the methodology should be of interest to PhD students in both the NGI and MMI themes.

If you have any questions or would like to attend, please e-mail Tristan Henderson (tnhh@st-andrews.ac.uk) before the 16th of July.

Abstract:
In contrast to the romantic image of an artist working in alone in a studio, large-scale media art pieces are often developed and built by interdisciplinary teams. Lindsay MacDonald will describe the process of creating and developing one of these pieces, A Delicate Agreement, within such a team, and offer personal insight on the impact that this has had her artistic practice.
A Delicate Agreement is a gaze-triggered interactive installation that explores the potentially awkward act of riding in an elevator with another person. It is a set of elevator doors with a peephole in each door that entices viewers to peer inside and observe an animation of the passengers. Each elevator passenger, or character, has a programmed personality that enables them to act and react to the other characters’ behaviour and the viewers’ gaze. The result is the emergence of a rich interactive narrative made up of encounters in the liminal time and space of an elevator ride.
A Delicate Agreement is currently part of the New Alberta Contemporaries exhibition at the Esker Foundation in Calgary, Canada. For more information about the piece, please visit http://www.lindsaymacdonald.net/portfolio/a-delicate-agreement/.

This week Aaron Quigley and Tristan Henderson attended Pervasive 2012, the Tenth International Conference on Pervasive Computing, at Newcastle University.
On Monday Aaron attended Pervasive Intelligibility the Second Workshop on Intelligibility and Control in Pervasive Computing. Here he presented a paper entitled Designing Mobile Computer Vision Applications for the Wild: Implications on Design and Intelligibility (PDF) by
Per Ola Kristensson, Jakub Dostal and Aaron Quigley. Later, he was a panelists with Judy Kay and Simone Stumpf where they discussed the research challenges of intelligibility with pervasive computing along with all participants.
On Tuesday Tristan attended the First Workshop on recent advances in behavior prediction and pro-active pervasive computing where he presented the paper Predicting location-sharing privacy preferences in social network applications by Greg Bigwood, Fehmi Ben Abdesslem and Tristan Henderson.
On Tuesday Aaron chaired the Doctoral Consortium with Elaine Huang from the University of Zurich with five panellists and nine students. The panellists were Adrian Friday, University of Lancaster, UK, Jin Nakazawa, Keio University, Japan and AJ Brush, Microsoft Research Seattle, USA.
The Pervasive 2012 doctoral consortium provided a collegial and supportive forum in which PhD students could present and defend their doctoral research-in-progress with constructive feedback and discussion. The consortium was guided by a panel of experienced researchers and practitioners with both academic and industrial experience. It offered students a valuable opportunity to receive high-quality feedback and fresh perspectives from recognised international experts in the field, and to engage with other senior doctoral students.
The day ended with a career Q&A session with an extended panel including Tristan Henderson from SACHI and Rene Mayhofer. Following this the panellists and students were able to have dinner together to continue active research and career discussions.
Along with work as a member of the joint steering committee of pervasive and UbiComp Aaron was a session chair for the HCI session on Thursday.

Last week (4-5 June, 2012) two papers from SACHI were presented at the Pervasive Displays international Symposium. The symposium took place in Porto, Portugal, and it was a great showcase of work on pervasive display systems from research groups in Europe, Japan and North America.
We presented two papers:
Factors Influencing Visual Attention Switch in Multi-Display User Interfaces: A Survey, which is part of the dissertation work of Umar Rashid, and
The LunchTable: A Multi-User, Multi-Display System for Information Sharing in Casual Group Interactions, which is part of collaborations with the ilab, at the University of Calgary.
Both papers were well-received and will be soon available through the ACM Digital Library, but the most interesting part was to share the energy of the pervasive displays community and the amazing discussions. We are hoping for a new edition next year, which will be in California.
