Abstract
Security surveillance represents a cognitively challenging task. To support surveillance operators, Thales Research and Technology Canada developed the Scantracker, which relies on real-time oculometric data to trigger notifications that mitigate camera negligence, attentional tunneling and vigilance decrement. Recently, this tool was adapted to augmented reality (AR), thus opening opportunities for design adjustments. This paper documents and demonstrates the utility of adopting a design thinking approach to improve the Scantracker and to adapt AR implementation to users’ needs. Surveillance operators took part in two design thinking workshops to evaluate and suggest improvements to the Scantraker from a user perspective. Then, the tool was adjusted and tested in a security surveillance simulation. Results of the design thinking workshop and the surveillance simulation are presented and discussed to support this user-centered approach for the development of cognitive-support tools for surveillance.
