Brinkman, Willem-Paul, Mast, Charles van der, Sandino, Guntur, Gunawan, Lucy T. and Emmelkamp, Paul M. G. (2010): The therapist user interface of a virtual reality exposure therapy system in the treatment of fear of flying. In Interacting with Computers, 22 (4) pp. 299-310.

“The use of virtual reality (VR) technology to support the treatment of patients with phobia, such as the fear of flying, is getting considerable research attention. Research mainly focuses on the patient experience and the effect of the treatment. In this paper, however, the focus is on the interaction therapists have with the system. Two studies are presented in which the therapist user interface is redesigned and evaluated. The first study was conducted in 2001 with the introduction of the system into the clinic. The original user interface design was compared with a redesign that was based on interviews with therapists. The results of a user study with five therapists and 11 students showed significant usability improvement. In 2008 a follow-up study was conducted on how therapists were now using the redesigned system. Using a direct observation approach six therapists were observed during a total of 14 sessions with patients. The analysis showed that: 93% of the exposures had similar patterns, therapists triggered 20 inappropriate sound recordings (e.g. the pilot giving height information while taking off), and more complex airplane simulation functions (e.g. roll control to make turns with the airplane) were only used by a therapist who was also a pilot. This resulted in a second redesign of the user interface, which allowed therapists to select flight scenarios (e.g. a flight with extra long taxiing, a flight with multiple taking off and landing sessions) instead of controlling the simulation manually. This new design was again evaluated with seven therapists. Again, results showed significant usability improvements. These findings led to five design guidelines with the main tenet in favour of a treatment-focused user interface (i.e. specific flying scenario) instead of a simulation-focused user interface (i.e. specific airplane controls).”

Brinkman, Willem-Paul, Mast, Charles van der, Payne, Annette and Underwood, Joshua (2008): HCI for Technology Enhanced Learning. In: Proceedings of the HCI08 Conference on People and Computers XXII 2008. pp. 185-186.

“The involvement of technology to support and enhance learning is ever increasing; for example moving from the traditional blackboard to electronic whiteboards, from printed books to virtual reality training simulations, and from class room meetings to (a-)synchronised meeting over the web with handheld mobile devices. These technologies promise improved efficiency for traditional ways of learning or even to open up totally new ways of learning. Designing technology-enhanced learning that engages learners in successful learning strategies requires an understanding of the learning context, learners' needs, motivations, habits and desires as well as ease of use. This workshop invites researchers, designers, and educators to discuss their work in this area and explore how HCI practices and methods can be applied or should be extended.”
