Presentation / Conference Contribution
Tang, H., Benerradi, J., Maior, H. A., Pike, M., Landowska, A., & Wilson, M. L. (2024, March). Exploring the Impact of Verbal-Imagery Cognitive Style on Web Search Behaviour and Mental Workload. Presented at CHIIR '24: Proceedings of the 2024 ACM SIGIR Conference on Human Information Interaction and Retrieval, Sheffield, UK

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...

The Impact of Motion Scaling and Haptic Guidance on Operators’ Workload and Performance in Teleoperation (2022)
Presentation / Conference Contribution
Parsa, S., Maior, H. A., Thumwood, A. R. E., Wilson, M. L., Hanheide, M., & Esfahani, A. G. (2022, April). The Impact of Motion Scaling and Haptic Guidance on Operators’ Workload and Performance in Teleoperation. Presented at CHI '22: CHI Conference on Human Factors in Computing Systems, New Orleans LA USA

The use of human operator managed robotics, especially for safety critical work, includes a shift from physically demanding to mentally challenging work, and new techniques for Human-Robot Interaction are being developed to make teleoperation easier...

Exploring Machine Learning Approaches for Classifying Mental Workload using fNIRS Data from HCI Tasks (2019)
Presentation / Conference Contribution
Benerradi, J., Maior, H. A., Marinescu, A., Clos, J., & Wilson, M. L. (2019, November). Exploring Machine Learning Approaches for Classifying Mental Workload using fNIRS Data from HCI Tasks. Presented at Halfway to the Future, Nottingham, UK

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...

Brain activity and mental workload associated with artistic practice (2018)
Presentation / Conference Contribution
Maior, H. A., Wilson, M. L., Locke, C., & Swann, D. (2018, April). Brain activity and mental workload associated with artistic practice. Presented at CHI 2018 Artistic BCI Workshop

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...

Mental workload as personal data: designing a cognitive activity tracker (2018)
Presentation / Conference Contribution
Wilson, M. L., Sharon, N., Maior, H. A., Midha, S., Craven, M. P., & Sharples, S. (2018, April). Mental workload as personal data: designing a cognitive activity tracker. Presented at 3rd Symposium on Computing and Mental Health: Understanding, Engaging, and Delighting Users

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...

Workload Alerts—Using Physiological Measures of Mental Workload to Provide Feedback During Tasks (2018)
Journal Article
Maior, H. A., Wilson, M. L., & Sharples, S. (2018). Workload Alerts—Using Physiological Measures of Mental Workload to Provide Feedback During Tasks. ACM Transactions on Computer-Human Interaction, 25(2), 1-30. https://doi.org/10.1145/3173380

Feedback is valuable for allowing us to improve on tasks. While retrospective feedback can help us improve for next time, feedback “in action” can allow us to improve the outcome of on-going tasks. In this paper, we use data from functional Near Infr... Read More about Workload Alerts—Using Physiological Measures of Mental Workload to Provide Feedback During Tasks.
