This poster presents a participatory study which results in a prototype application for Android mobile devices mounted in affordable Virtual Reality headsets, to explore the potential of Virtual Reality Exposure Therapy through realistic immersive experiences in order to help people with hidden disabilities to develop tolerance to the environmental stressors that are typically found in crowded public spaces, and more particularly in airports. The application initially proposes users to rehearse a series of sensory attenuated experiences within digitally reconstructed environments of Aberdeen International Airport. Throughout rehearsals, environmental stressors are gradually increased making the environments more challenging for users. Usability testing was carried out and outcomes are encouraging whereas pilot testing on a small cohort of participants is currently being conducted.
