Aaron Quigley, Inaugural Lecture on HCI


Today Professor Aaron Quigley will be giving his Inaugural Lecture in School III
The abstract for his talk is as follows: Billions of people are using interconnected computers and have come to rely on the computational power they afford us, to support their lives, or advance our global economy and society. However, how we interact with this computation is often limited to little “windows of interaction” with mobile and desktop devices which aren’t fully suited to their contexts of use. Consider the surgeon operating, the child learning to write or the pedestrian navigating a city and ask are the current devices and forms of human computer interaction as fluent as they might be? I contend there is a division between the physical world in which we live our lives and the digital space where the power of computation currently resides. Many day to day tasks or even forms of work are poorly supported by access to appropriate digital information. In this talk I will provide an overview of research I’ve been pursuing to bridge this digital-physical divide and my future research plans. This talk will be framed around three interrelated topics. Ubiquitous Computing, Novel Interfaces and Visualisation. Ubiquitous Computing is a model of computing in which computation is everywhere and computer functions are integrated into everything. Everyday objects are sites for sensing, input, processing along with user output. Novel Interfaces, which draw the user interface closer to the physical world, both in terms of input to the system and output from the system. Finally, the use of computer-supported interactive visual representations of data to amplify cognition with visualisation. In this talk I will demonstrate that advances in human computer interaction require insights and research from across the sciences and humanities if we are to bridge this digital-physical divide.

Aaron delivers and invited seminar in the University of Zurich


Professor Quigley is presenting a seminar in the University of Zurich as an invited speaker by Dr Elaine Huang.
Seminar abstract: Our bodies shape our experience of the world, and our bodies influence what we design. How important are the physical differences between people? Can we model the physiological differences and use the models to adapt and personalize designs, user interfaces and artefacts? Can we model, measure and predict the cost of users altering their gaze in single or multi-display environments? If so, can we personalize interfaces using this knowledge. What about when moving and while the distance between user and screen is varying. Can this be considered a new modality and used to personalize the interfaces along with physiological differences and our current gaze. In this talk we seek to answer some of these questions. We introduce an Individual Observer Model of human eyesight, which we use to simulate 3600 biologically valid human eyes. We also report on controlled lab and outdoor experiments with real users. This is to measure both gaze and distance from the screen in an attempt to quantify the cost of attention switching along with the use of distance as a modality. In each case, for distance, gaze or expected eyesight we would like to develop models which can allow us to make predictions about how easy or hard it is to see visual information and visual designs, along with altering the designs to suit individual users based on their current context.

Today's slashdot.org logo created by SACHI PhD student


Today’s logo at slashdot.org was created by Jason Jacques, a new PhD student in the SACHI group!
From slashdot.org: Artist Jason Jacques says: “While the main text itself is “obvious” in its fully animated form this logo provides additional challenge in that the remainder of the message must be decoded. Can you figure it out? If so, mail answer to logo15@slashdot.org. How did he do it? After calculating the necessary sizes and bit patterns on paper, the static image of the entire message was generated using Pixlemator on Mac OS X (Lion). This image was then processed using ImageMagick (and a short shell script) using Ubuntu. Additional editing was done to the logo portion in Pixelmator (OS X). These frames were then assembled into an animated gif using Jasc Animation Shop on Windows XP. Finally, the images were optimized to minimise their size using ImageOptim, back on OS X.”

Welcome to Uta Hinrichs


Welcome to Uta Hinrichs who has joined the SACHI group from the University of Calgary, Canada as a Research Fellow. Uta holds a Diplom (equiv. to MSc) in Computational Visualistics from the University of Magdeburg in Germany and is in the process of finishing her PhD in Computer Science with a specialization in Computational Media Design. Uta’s PhD research, that she conducted at the InnoVis Group of the University of Calgary, focuses on how to support open-ended information exploration on large displays in public exhibition spaces, combining information visualization with direct-touch interaction techniques. As part of this research, she has designed and studied large display installations in the context of a museum and art gallery, library, and an aquarium.

Laurel Riek, Facing Healthcare's Future: Designing Facial Expressivity for Robotic Patient Mannequins


<!–Speaker: Laurel Riek, Computer Science and Engineering University of Notre Dame
Date/Time: 1-2pm September 4, 2012
Location: 1.33a Jack Cole, University of St Andrews (directions)–>
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.

PhD Studentship on Perceptual Gaze-contingent Displays at St Andrews


The SACHI group (Human-Computer Interaction) at the University of St Andrews, Scotland’s first university, is offering a full scholarship to join the School of Computer Science as a doctoral researcher for 3.5 years. The scholarship covers tuition fees and provides a living-expenses stipend.
The work will focus on the creation of new forms of visualization with gaze-contingent displays (electronic displays that have access to the location of the person’s gaze), their evaluation through laboratory studies, and the implementation of new visualization and interaction techniques. The student will work closely with Dr. Miguel Nacenta and within the SACHI group.
Please, visit Dr. Nacenta’s site for more detail.
