Exploring the Impact of Verbal-Imagery Cognitive Style on Web Search Behaviour and Mental Workload (2024)
Conference Proceeding

Cognitive style has been shown to influence users’ interaction with search interfaces. However, as a fundamental dimension of cognitive styles, the relationship between the Verbal-Imagery (VI) cognitive style dimension and search behaviour has not be...

Exploring Machine Learning Approaches for Classifying Mental Workload using fNIRS Data from HCI Tasks (2019)
Conference Proceeding

Functional Near-Infrared Spectroscopy (fNIRS) has shown promise for being potentially more suitable (than e.g. EEG) for brain-based Human Computer Interaction (HCI). While some machine learning approaches have been used in prior HCI work, this paper...

Improvising a Live Score to an Interactive Brain-Controlled Film (2019)
Conference Proceeding

We report on the design and deployment of systems for the performance of live score accompaniment to an interactive movie by a Networked Musical Ensemble. In this case, the audiovisual content of the movie is selected in real time based on user input... Read More about Improvising a Live Score to an Interactive Brain-Controlled Film.

Enslaved to the Trapped Data: A Cognitive Work Analysis of Medical Systematic Reviews (2019)
Conference Proceeding

Systematic reviews are a comprehensive and parameterised form of literature review, found in most disciplines, that involve exhaustive analyses and rigorous interpretation of prior literature. Performing systematic reviews, however, can involve repet... Read More about Enslaved to the Trapped Data: A Cognitive Work Analysis of Medical Systematic Reviews.

When size matters: Towards evaluating perceivability of choropleths (2018)
Conference Proceeding

Choropleth maps are an invaluable visualization type for mapping geo-spatial data. One advantage to a choropleth map over other geospatial visualizations such as cartograms is the familiarity of a non-distorted landmass. However, this causes challeng...

Brain activity and mental workload associated with artistic practice (2018)
Conference Proceeding

We present the first stage of our on-going artist-driven BCI collaboration, where we equipped an artist with the brain scanning technique functional Near Infrared Spectroscopy (fNIRS) in order to record mental workload levels during her creative prac... Read More about Brain activity and mental workload associated with artistic practice.

Mental workload as personal data: designing a cognitive activity tracker (2018)
Conference Proceeding

Research continues to correlate physical signals with mental activity, as opposed to physical activity, with physiological sensors. Further, with the proliferation of wearable technology, it seems imminent that our smart watches can soon keep track o... Read More about Mental workload as personal data: designing a cognitive activity tracker.

#Scanners 2 – The MOMENT: a new brain-controlled movie (2018)
Conference Proceeding

While many still consider interactive movies an unrealistic idea, current delivery platforms like Netflix, commercial VR, and the proliferation of wearable sensors mean that adaptive and responsive entertainment experiences are an immediate reality....

How stress affects functional near-infrared spectroscopy (fNIRS) measurements of mental workload (2018)
Conference Proceeding

Recent work has demonstrated that functional Near-Infrared Spectroscopy has the potential to measure changes in Mental Workload with increasing ecological validity. It is not clear, however, whether these measurements are affected by anxiety and stre...

Measuring mental workload in IIR user studies with fNIRS (2017)
Conference Proceeding

Gathering neuro-physiological data during user studies, and analysing the continuous data they produce, typically involves making a tradeoff between detail and practical utility. is paper describes our long-term work-in-progress towards developing... Read More about Measuring mental workload in IIR user studies with fNIRS.

The Tetris model of resolving information needs within the information seeking process (2017)
Conference Proceeding

Theoretical abstractions, of many different aspects of search, have played a crucial role in driving research into human information seeking and retrieval forward. From models of the Information Seeking Process, to how we perceive search systems, the... Read More about The Tetris model of resolving information needs within the information seeking process.

Search literacy: learning to search to learn (2016)
Conference Proceeding

People can often find themselves out of their depth when they face knowledge-based problems, such as faulty technology, or medical concerns. This can also happen in everyday domains that users are simply inexperienced with, like cooking. These are co... Read More about Search literacy: learning to search to learn.

#Scanners: Exploring the Control of Adaptive Films using Brain-Computer Interaction (2016)
Conference Proceeding

This paper explores the design space of bio-responsive entertainment, in this case using a film that responds to the brain and blink data of users. A film was created with four parallel channels of footage, where blinking and levels of attention and...

Using fNIRS in usability testing: understanding the effect of web form layout on mental workload (2016)
Conference Proceeding

Amongst the many tasks in our lives, we encounter web forms on a regular basis, whether they are mundane like registering for a website, or complex and important like tax returns. There are many aspects of Usability, but one concern for user interfac... Read More about Using fNIRS in usability testing: understanding the effect of web form layout on mental workload.

Active and passive utility of search interface features in different information seeking task stages (2016)
Conference Proceeding

Models of information seeking, including Kuhlthau’s information Search Process model, describe fundamentally different macro-level stages. Current search systems usually do not provide support for these stages, but provide a static set of features pr...

Exploring opportunities to facilitate serendipity in search (2015)
Conference Proceeding

Serendipitously discovering new information can bring many benefits. Although we can design systems to highlight serendipitous information, serendipity cannot be easily orchestrated and is thus hard to study. In this paper, we deployed a working sear...
