I was honoured to be invited to talk about Positive Computing at a TEDx event this month. The theme of the event was “Think, Act, Evolve” and it was humbling to be included with a group of diverse and inspiring speakers including artists, activists and entrepreneurs. The talks will be made available online within the next few months.
- Project supporting mental health with technology
- Opportunity to develop your research profile in human-computer interaction, mental health and wellbeing
- 3 year contract.
The purpose of the Sydney fellowship is to attract talented recent doctoral graduates who can contribute to our whole-of-university multidisciplinary initiatives, broadly construed. In particular we are looking for young researchers to work at the intersection of computing and mental health.
We are seeking to appoint a postdoctoral researcher to develop and evaluate the new technologies for mental health and wellbeing. The specific project to be agreed with the supervisor/s but likely in the area of mobile interventions or virtual reality
- assist in further development of Internet based mental health interventions, based on findings and outcomes in the literature and other projects.
- assist in the design, development, and evaluation of a website for the deployment of mental health interventions.
- take the lead in the writing up of reports, peer reviewed journal articles and conference papers/presentations.
- assist in obtaining ethics clearance for the qualitative and quantitative phases of the research and evaluation.
- liaise with the various stakeholders on the project informing them of project progress and that the research is directly related to end user needs.
To secure this role you must have:
- a PhD in Software Engineering, Computer Science or psychology
- excellent quantitative research skills.
- strong verbal and written communication skills.
- ability to work well as part of a team.
- ability to meet tight work deadlines.
- strong publication record

The leading online review service for computing literature had a nice piece about our book.
“This book provides an excellent look at how computers can become our handmaidens, helping to make our personal lives better. As the authors state, they investigate what they term positive computing: “the design and development of technology to support psychological wellbeing and human potential” (p. 2).”
“But positive computing done right has the potential to provide enhancements to our lives and create a symbiotic relationship between the person and the technology.”
This symposium is a great sample of Australian researchers, in he social sciences, and their really interesting ideas on where Big data can take us. It would be nice to also have people with a technical background be part of these discussions – maybe next time. I love the topics!
Tomorrow the Big Data Cultures symposium that I have convened at the University of Canberra is taking place. There is a very interesting program from a range of Australian academics working on the social, cultural and political dimensions of the big data phenomenon. Here are the abstracts:
Keynote: ‘Visual dimensions’
Greg More, RMIT University
It’s a small problem for data to scale, but a wicked problem for us to make sense of big data that scales to infinity. The aim of this article is to explore the translation of data into geometrical relationships: the art and design of creative forms of data visualisation to give data a meaningful visual dimension. Data has dimensionality, but not in a geometrical sense. Topology – the mathematical study of shape – will be used as lens to examine projects where designers utilise metaphors and abstraction to construct visual languages for data. Consider this cartography…

Critical review skill is one important aspect of academic writing. Generic trigger questions have been widely used to support this activity. When students have a concrete topic in mind, trigger questions are less effective if they are too general. This article presents a learning-to-rank based system which automatically generates specific trigger questions from citations for critical review support. The performance of the proposed question ranking models was evaluated and the quality of generated questions is reported. Experimental results showed an accuracy of 75.8% on the top 25% ranked questions. These top ranked questions are as useful for self-reflection as questions generated by human tutors and supervisors. A qualitative analysis was also conducted using an information seeking question taxonomy in order to further analyze the questions generated by humans. The analysis revealed that explanation and association questions are the most frequent question types and that the explanation questions are considered the most valuables by student writers.
I am privileged to be part of the LEADS partnership, a research network led by Susanne Lajoie at McGill University. This paperthe first coming from our subproject – with a rather long title “Systematic Evaluation of the Effectiveness of TREs through Software Platform Development for Data Mining across Multiple Disciplines and Tracking Changes in Affective and Cognitive Growths”

Abstract. In this paper we discuss the methodology and results of aligning three different emotional measurement methods (automatic facial expression recognition, self-report, electrodermal activation) and their agreement regarding learners’ emotions. Data was collected from 67 undergraduate students from a North American university who interacted with MetaTutor, an intelligent, multi-agent, hypermedia environment for learning about the human circulatory system, for a 1 hour learning session (Azevedo et al., 2013, Harley, Bouchet, & Azevedo, 2013). A webcam was used to capture videos of learners’ facial expressions, which were analyzed using automatic facial recognition software (FaceReader 5.0). Learners’ physiological arousal was measured using Affectiva’s Q-Sensor 2.0 electrodermal activation bracelet. Learners self-reported their experience of 19 different emotional states (including basic, learner-centered, and academic achievement emotions) using the Emotion-Value questionnaire (Harley et al., 2013). They did so on five different occasions during the learning session, which were used as markers to align data from FaceReader and Q-Sensor. We found a high agreement between the facial and self-report data (75.6%) when similar emotions were grouped together along theoretical dimensions and definitions (e.g., anger and frustration) (Harley, et al., 2013). However, our new results examining the agreement between the Q-Sensor and these two methods suggests that electrodermal (EDA/physiological) indices of emotions do not have a tightly coupled (Gross, Sheppes, & Urry, 2011) relationship with them. Explanations for this finding are discussed.

Unobtrusive, contactless recordings of physiological signals is very important for many health and human-computer interaction applications. Most current systems require sensors which intrusively touch the user’s skin. Recent advances in contact-free physiological signals open the door to many new types of applications. This technology promises to measure heart rate (HR) and respiration using video only.
