HCC (and friends) in 108 (and nearby)
This is a discussion group for people working in human centred computing, HCI, gestures, eye gaze, facial expressions, generating art or music, and similar fields. Everyone is welcome.
We meet every second Tuesday, from 4-5pm, in the N332 seminar room in the ANU CS&IT building. RSCS are kind enough to provide wine (and soft drinks) and cheese. The meetings are advertised here, and via an email list
"HCC and friends" aims to encourage discussion between people working in similar fields; to provide a venue for feedback on work in progress; and to get people from different groups talking to each other.
Want to present something? If there's any work in progress (or completed, or not really started) which you would like to share over wine and cheese, please let Dingyun or Tom know. You don't need finished work, and you don't need an hour's worth of fancy slides, just a willingness to talk about what you're up to. The idea is to get discussion going, not to present eternal verities.

Analysis of Reading Comprehension using Eye Gaze
There are several reading detection algorithms in the literature that are used at present to detect when a user is reading or skimming or scanning a document. We want to extend this theory to detected when a user is having difficulty understanding text. To do so a user study was conducted to collect participants eye gaze as they read a tutorial and completed a quiz to test their understanding of the tutorial content. When the questions are then presented to the participants, they are also given the opportunity to re-read the tutorial content to help them identify the answers. Some initial results and findings from the data collected are presented.

Wands are Magic: A comparison of devices used in 3D pointing interfaces
In our pilot study with 12 participants, we compared three interfaces, 3D mouse, glove and wand in a 3D naturalistic environment. The latter two were controlled by the same absolute pointing method and so are essentially identical except for the selection mechanism, grasp action versus button. We found that the mouse performed worst in terms of both time and errors which is reasonable for a relative pointing device in an absolute pointing setting, with the wand both outperforming and favored by users to the glove. We conclude that the presence of a held object in a pointing interface changes the users perception of the system and magically leads to a different experience.

Live coding with Extempore
'Live coding' is the act of programming (writing code) as a performance performance---in front of an audience---usually in the domain of music and multimedia art. Livecoding is a fascinating programming activity from a human factors perspective. The livecoder must construct a working programs in a short period of time with an aesthetically pleasing end product, all under the pressure of coding in front of a live audience.
Extempore is a new programming language & environment for live coding being developed (in part) here at the ANU. This 'iHCC and Friends' talk will cover the basics of Extempore and live coding, and will finish with a live coding performance.

Remote SARs and 3D
Spatial Augmented Reality (SAR) systems can be used to convey guidance in a physical task from a remote expert. Sometimes that remote expert is provided with a single camera view of the workspace but, if they are given a live captured 3D model and can freely control their point of view, the local worker needs to know what the remote expert can see. In this HCC and Friends session, we’ll discuss three new SAR techniques, Composite Wedge, Vector Boxes, and Eyelight, for visualizing off-surface 3D viewpoints and supporting the required workspace awareness.

Music Making, Machine Learning and the Third Wave
As HCI matures, computer-supported play and creativity in contexts such as improvisational group music making are becoming more common. In these situations, things like success and "user experience" are difficult to measure reliably. Yet the digital nature of these systems allows us to instrument and log these activities in great detail. While being sensitive to our inability to measure all the sociomaterial nuances of these activities, what can we learn from this data?

Cyborg Rights
IEEE Technology and Society 30, 3 (Fall 2011) 49-57
http://www.rogerclarke.com/SOS/CyRts-1102.html
The first generation of cyborgs is alive, well, walking among us, and even running. Pacemakers, renal dialysis machines and clumsy mechanical hands may not match the movie-image of cyborg enhancements, but they have been the leading wave. The legs of sprinter Oscar Pistorius, and implants of both the cochlear and RFID varieties, make more substantial changes to individuals. They also pose greater challenges to society as a whole.Cyborgisation will give rise to demands for new rights. People who have lost capabilities but have not yet got the relevant prostheses will seek the right to have them. Some people will demand the right not just to recover what they are missing, but also to enhance themselves. Others will demand the liberty not to have prostheses imposed on them. Enhanced humans will seek additional rights to go with the additional capabilities that they have. The political processes involved in lobbying for and resisting these desires will take many and varied forms.
Professional engineers have an obligation to anticipate these developments, and to brief political, social and economic institutions on their nature, impact and implications. They have to date failed to do so. The rate of change is sufficiently brisk that action is urgent.

Rebalance
'Rebalanced' was a digital media work exhibited in 'Art Machine' in 2011. It's production exemplified some similarities and some tensions between artistic practice and professional programming practice.Tim will use images and a little code to describe the creative process that lead to 'Rebalanced'. In doing so, he will explore some new or forgotten byways of colour theory, algebra, crowd sourcing, art history, stochastic processes and Java classes.

Natural Interaction for Viewpoint Control in Teleoperation
This research work focuses on the design and evaluation of natural interaction enhanced user interfaces for viewpoint control in teleoperation. Examples of natural interaction modes include human eye gaze, head motion, and gestures. Augmenting traditional control interfaces (which use input devices such as joysticks, keyboards and mice) with these natural interaction modes offer the possibility of creating machine control interfaces that are easier to learn, and provide more effective control of complex machinery than traditional systems.

Perspectives on Digital Image Credibility and Authentication
The debate about photography being science or art began over 150 years ago and is still an open question, especially in light of the relatively recent introduction of digital photography and the photo manipulation software that came with it. When does a photograph cease being a representation of something real and become photo art? Why does it matter and what can we do about it? This talk takes a cross-disciplinary approach to digital image credibility, looking at these questions as well as the technological aspects of digital image capture, processing and file outputs that may allow for an 'in-camera' photograph authentication process.

Design and delivery of a course in ICT Sustainability using the Internet and eBooks
Sustainable ICT Courses are being introduced at the vocational training level and more rarely at undergraduate and graduate levels. This presentation discusses a graduate level Sustainable ICT Course run for the first time in 2009, as part of a global professional training program. The same course has been run at an Australian university and later adapted for North America. The course has enrolments from industry based participants from both private and public sector organizations, as well as full time university students, with corporate Green ICT strategies being produced as course assignments. This paper discusses the student population and presents the course structure and assessment. This is a preview of a presentation for the 7th International Conference on Computer Science & Education (ICCSE 2011) in Melbourne, July 2012.

De-conditioning of decisions or inverse Bayesianism
The pun in the title is to suggest that *inverting* the common Bayesian process of computing conditional probabilities and using those as the basis of decision making can be profitably inverted. Specifically, we propose a formalism for inverting the process of probabilistic conditioning. It is based on judicious use of the MaxEnt principle; it can be justified, among others, by the fact that the standard conditioning can be *derived* through the MaxEnt methods.
The inverse conditioning lead to a novel framework for combining independent distributions. The result is *additive* - a form of a sum in a suitable category, rather than the standard *multiplicative* one - a product in such a category.
The numerical results are attractive and intuitively plausible. They can be applied in several scenarios. We outline a few: modeling of trust based on indirect reports, interpretation of the canonical law concept of 'half-truth', or combining the question scores in the exams.
The first example has applications to e-commerce and to security; the second may be relevant to decision about torture; the last one is directly applicable to the newest educational paradigm - MOOC (massive open online courseware).
The talk is suitable for those interested in any of such topics. The only requirement is understanding of basic probability concepts and their use in decision processes.

Serious computer games for motor rehabilitation
Serious computer games developed for motor rehabilitation produce a more engaging and enjoyable method to participate in physical therapy, but lack of variation and a secondary focus on fun limit long-term appeal. Traditionally, the focus of serious games in a health context is on the rehabilitation of motor function, neglecting the often-absent or impaired sensory function of the patient. This paper discusses a series of approaches used to develop appropriate serious games for children with cerebral palsy targeted at the impaired sensory system, taking into consideration longevity of play experience, requirements from therapists or researchers, and the interface requirements of the participants themselves. Two of the games that were developed are provided as examples, including data and feedback from one child with cerebral palsy who evaluated the games for entertainment, engagement and replay value.

Using Magnetic Forces to Convey State Information: an Exploration of a Haptic Technology
Using magnetic forces to provide haptic information is an area that remains largely unexplored and provides exciting opportunities for interaction that may not otherwise be possible. We present several example applications that illustrate how this technology is well suited to remote site collaboration techniques, conveying state information and simulating flows and turbulence. Furthermore, we present the results of our preliminary user study which has indicated that magnetic forces can convey two states of information to the user with 100% accuracy, and can convey three states with 89% accuracy.

Tablet Interaction Techniques for Viewport Navigation on Large Displays
While a subset view on tablet devices allows users to observe in detail an area of the large display from a distance, interaction techniques are required to support viewport navigation around the display efficiently. We propose two dual-touch techniques (DualTaP and DirectTaP) for moving and scaling the viewport simultaneously. We also explore two orientation-based techniques (TabTilt and TabPoint) inspired by their usage in game controls. In our user study, we found that the DualTaP technique out performs the rest due to its speed and overall preference for simultaneously defining both the size and position of the viewport. We discuss our findings and suggests potential applications for using these techniques on large displays.

Gesture-based manipulation of medical image data during surgery
Surgeons often use medical image data, such as CT and MRI scans of the patient, to plan the surgery and they are interested in having the same access to that data in the operating theatre during surgery. As part of an ARC Linkage grant with Microsoft the Research School has an early-stage project to explore how this might work. This talk will explore ideas and issues involved in the project and look at some of the early prototyping that might take place and will include discussion from other members of the project team.
Duncan Stevenson is an Adjunct Associate Professor in the Research School of Computer Science at the ANU. Previously he worked for many years in the CSIRO ICT Centre in Canberra and he completed his PhD in computer science during the transition from CSIRO to ANU. His interests in Human-Computer Interaction include the requirements, scoping and early prototype phases for industrial applications of ICT technologies.

Physical Sonification Dataforms
This seminar describes a research project that combines creative practice with design process and scientific method. The project began with a competition to sonify a dataset that measures human spatial hearing, consisting of 360 audio filters with 1024 point spectral profiles for both left and right ear. The design process addressed the problem described by the brief through an iterative cycle of prototyping and evaluation. The creative practice involved an intuitive exploration of materials, forms and acoustics produced with new 3D printing technology and techniques. The scientific method consisted of the analytical observation and identification of testable hypotheses to guide further design and practice.
The result is a series of asymmetrical bell-like objects that produce audible tones when struck. The dataset used to construct these bells was assumed to be symmetrical by the scientist who measured it. However the bell for each ear sounds different, and there were indeed differences in the left and right ear data that were not expected to be there. Were the differences in bell tones really pointing to these artefacts of measurement, or was it just a coincidence? Were the differences in tone due to variations in the 3D digital printing process and materials instead? By the time of this seminar I hope to be able to tell you. In either case, the ability to immediately hear differences that are not readily apparent in the source data, or visual forms of it, indicates the potential of Physical Sonification as a new technique for understanding digital datasets.
The observation and documentation of this multidisciplinary approach combining art, design and science is also an outcome of the project. This presentation will describe the approach so that it may be re-used and built upon.
