Reminder of the Cognitive Area Seminar this week:

Creating a dynamic measure of the useful field of view using gaze-contingent displays Aaron Johnson Concordia University Abstract: Safety and survival in many real-world tasks require an observer to rapidly respond to information presented in their peripheral vision. Importantly, people differ in their ability to rapidly detect information in their visual periphery, as shown by measures of the Useful Field of View (UFOV). The UFOV measure reliably predicts their performance in a number of safety-critical real world tasks, such as driving, and can vary from moment-to-moment based on mental workload or stress level. However, the standardized UFOV(c) measure is a stand-alone instrument, and cannot be easily integrated into complex dynamic displays such as simulators and virtual reality. In this talk, I will describe the development of a novel contextualized analogue of the UFOV measure that can be easily ported to such dynamic displays and training environments. To implement this measure of the UFOV, we use gaze-contingent displays, which use eye tracking to put intact imagery in a circular region centered on where the viewer is looking, and alter the imagery everywhere else, and rapidly move the center of intact imagery every time the viewer moves their eyes. I will show three different measures that we have used to measure the UFOV, and evaluate the efficacy of the gaze-contingent measure under conditions of low and high cognitive load in both traditional laboratory, and in simulated realistic task environments.

Friday, February 13th, 15h30-17h00 Stewart Biology Building, W7/21
