An expressive virtual audience with flexible behavioral styles

Currently, expressive virtual humans are used in psychological research, training, and psychotherapy. However, the behavior of these virtual humans is usually scripted and therefore cannot be modified freely at runtime. To address this, we created a virtual audience with parameterized behavioral styles. This paper presents a parameterized...

Effects of mobile support on situation awareness and navigation in a field and game environment

For surveillance and rescue operations, human navigation and situation awareness should be well-supported. However, proper testing of new and innovative mobile support is hard for such operations. Evaluations in field settings are expensive, difficult to control, potentially dangerous, and may sometimes be impossible to execute. Using a virtual...

Controlling social stress in virtual reality environments

Virtual reality exposure therapy has been proposed as a viable alternative in the treatment of anxiety disorders, including social anxiety disorder. Therapists could benefit from extensive control of anxiety eliciting stimuli during virtual exposure. Two stimuli controls are studied in this study: the social dialogue situation, and the dialogue...

Gamification for low-literates: Findings on motivation, user experience, and study design

This study investigated the effects of the gamification elements of scaffolding, score and hints on the user enjoyment and motivation of people of low literacy. In a four-condition within-subjects experiment, participants per-formed mental spatial ability tests with the aforementioned elements. Quantitative results were inconclusive, but post...

Child's recognition of emotions in robot's face and body

Social robots can comfort and support children who have to cope with chronic diseases. In previous studies, a "facial robot", the iCat, proved to show well-recognized emotional expressions that are important in social interactions. The question is if a mobile robot without a face, the Nao, can express emotions with its body. First, dynamic body...

Internet-delivered multi-patient virtual reality exposure therapy system for the treatment of anxiety disorders

Design and implementation of home-based virtual reality exposure therapy system with a virtual eCoach

Current developments of virtual reality exposure therapy (VRET) system focus mainly on systems that can be used in health clinics under the direct supervision of a therapist. Offering patients however the possibility to do this treatment at home would make VRET more accessible. In this paper we therefore present a home-based VRET system for the...
