People with social phobia have a severe fear of everyday social situations. In this paper we describe a virtual reality exposure therapy system specifically designed to expose patients with social phobia to various social situations. Patients can engage in a free speech dialogue with avatars while being monitored by a therapist. To control phobic stressors, therapists can control the avatar’s gaze, the avatar’s dialogue style and the narrative stories that are embedded throughout the exposure. The system uses the Delft remote virtual reality exposure therapy platform which allows remote treatment.
