vrSocial: Toward Immersive Therapeutic VR Systems for Children with Autism

Social communication frequently includes nuanced nonverbal communication cues, including eye contact, gestures, facial expressions, body language, and tone of voice. This type of communication is central to face-to-face interaction, but can be challenging for children and adults with autism. Innovative technologies can provide support by augmenting human-delivered cuing and automated prompting. Specifically, immersive virtual reality (VR) offers an option to generalize social skill interventions by concretizing nonverbal information in real-time social interactions. In this work, we explore the design and evaluation of three nonverbal communication applications in immersive VR. The results of this work indicate that delivering real-time visualizations of proximity, speaker volume, and duration of one's speech is feasible in immersive VR and effective for real-time support for proximity regulation for children with autism. We conclude with design considerations for therapeutic VR systems.
