ACM CHI’23 paper Quantifying eye-cursor coordination during remote, online drag-and-drop user interactions
Jennifer Bertrand & Craig Chapman
Fully remote and online, we used cursor-tracking and webcam eye-tracking to explore the dynamics of eye-cursor coordination for digital drag-and-drop user interactions.

manuscript forthcoming (under submission)Remotely assessing decision difficulty: complementing cursor-tracking with insights from webcam eye-tracking
Jennifer Bertrand, Alexandra Ouellette Zuk & Craig Chapman
This project extends our earlier work (cursor-tracking only - see below) by exploring how webcam eye-tracking can provide unique insights about decision difficulty that we can’t capture from cursor-tracking alone.
This project is currently under submission - read our pre-print here!
in press at JEP:HPPReading player intentions from mouse-cursor movements in a two-player remote card game
Helen Ma, Jennifer Bertrand, Craig Chapman & Dana Hayward
This work involved the building and deployment of a remote, online two-player card game where players could see each others’ mouse cursors throughout the game. We made some games competitive and some cooperative, and people moved their mouse cursors differently between contexts.
This project has been accepted for publication and is in press at the Journal of Experimental Psychology: Human Perception and Performance (JEP: HPP).
manuscript forthcoming (under submission)Decision difficulty reflected in both mouse cursor and touchscreen dynamics
Alexandra Ouellette Zuk, Jennifer Bertrand & Craig Chapman
Across 3 types of decisions, we remotely tested people using computers, tablets or smartphones, measuring their mouse cursor or touchscreen interactions. We’ve found rich decision difficulty information revealed in the movements of both mouse and touch interactions.

Remote and Online Methods to Measure Human Behaviour
in prepA Practical Guide to Remote Webcam Eye-tracking
Jennifer Bertrand & Craig Chapman As a product of the journey we embarked on when the pandemic shifted our research from the lab to the internet, we learned A LOT of lessons (often the hard way) to arrive at high-quality webcam eye-tracking data from remote participants.
As one of the first papers of its kind for webcam eye-tracking, we offer a comprehensive guide about all the practical aspects of running remote webcam eye-tracking experiments, and add data-backed insights about eye-tracking quality, experimental costs and effective data collection strategies.
This project is in preparation for publication. Pre-print forthcoming.

Brain rhythms and flicker: measuring phase coherance with EEG
Using electroencephalography (EEG), we show that theta frequency brain rhythms are predictive of brightness enhancement from flickering stimuli.
-
Rapid reach decisions with dynamic probabilistic information
With motion capture recordings we reveal that rapid reach decisions accurately reflect the future state of dynamic probabilistic information.
-
Identifying the way brightness enhancement varies with flicker frequency
In a two-part behavioural experiment, we determined the frequencies of flicker that generate the greatest brightness enhancement.
