James Nicholson is currently working on various projects evaluating the usability of existing systems and influencing the design of future systems.
James has carried out extensive work evaluating the Panopticon parallel video overview system in a variety of contexts, including eLearning, surveillance monitoring, and currently using headmounted technology. He is also involved with NINEtoFIVE, an anonymous online employee voice platform.
From a security perspective James has explored factors that contribute to engagement and accuracy of crowdsourced viewers when watching surveillance video to the internet and methods of improving the composition of passwords for users in terms of both memorability and entropy.
James’ work has focused on improving user authentication, both by repurposing existing graphical authentication systems and by evaluating novel ones. James is also interested in user privacy and how groups of users (children, parents, older adults) experience location tracking technologies, as well as how CCTV video can be crowdsourced to de-centralise the surveillance landscape. More recently, James have developed tools and methodologies for uncovering and understanding employees’ mental models of security threats with the aim of improving training programmes and/or organisational policies, as well as practical means for improving users’ protection against these security threats (e.g. phishing).
James obtained his PhD in Human-Computer Interaction from Northumbria University in 2013. He has a BSc (Information Systems) from Newcastle University and a Masters of Research in Psychology from Northumbria University.
