Smart cities are complex configurations of technology, organisations and people that enable data about the city to be collected and flow to those who plan and deliver services in cities, leading to better urban outcomes for citizens and businesses. Platforms play a critical role in smart cities and in broader digital disruption across all industrie...
Conference Paper
Human trust is a psycho-physiological state that is difficult to measure, yet is becoming increasingly important for the design of human-computer interactions. This paper explores if human trust can be measured using physiological measures when interacting with a computer interface, and how it correlates with cognitive load. In this work, we presen...

HCI systems that bypass manual control can be beneficial for many use cases, including users with severe motor disability. We investigated pupillometry (inferring mental activity via dilations of the pupil) as an interaction method because it is non-invasive, easy to analyse, and increasingly available for practical development. In 3 experiments we...

For individuals with high degrees of motor disability or locked-in syndrome, it is impractical or impossible to use mechanical switches to interact with electronic devices. Brain computer interfaces (BCIs) can use motor imagery to detect interaction intention from users but lack the accuracy of mechanical switches. Hence, there exists a strong need...

We explore and test the suitability of four interfaces for tele-operation in Human-Robot Interaction. In a "pick-and-place" task, users select tar- gets and locations using eye-tracking (activated by either a mouse-click or by dwell time), a touchscreen, or a standard computer mouse. We validated our hypotheses in two user studies. Contrary to our...

By overlaying virtual guidance information directly over the surrounding environment, Augmented Reality (AR) is seen as an easy alternative to maps for pedestrians navigating in unfamiliar urban environments. It is hypothesized, however, that easing navigation tasks would result in weaker cognitive maps, leaving users more vulnerable to becoming lo...

Various ways for delivering exposure treatment to phobic people have been developed and investigated. These range from traditional live exposure to mixed reality exposure to fully virtual exposure approaches, each with specific advantages and disadvantages in delivering exposure of phobia inducing stimuli. In previous research we have argued for sp...
