“…However, this group effect should be regarded under consideration of the gaze type analysis, which indicated a reduced focus on the partners' gaze signal (i.e., more gaze types excluding RoI gaze). This is in line with other studies showing reduced eye region focus in observers with ASD (Madipakkam et al, 2017;Papagiannopoulou et al, 2014;Robles et al, 2022;Roth et al, 2020;Tanaka & Sung, 2016). As the gaze signal was the faster signal, a reduced focus on the partner's eye region could at least partially explain the deceleration of response times.…”

Temporal coordination of communicative behavior is not only located between but also within interaction partners (e.g., gaze and gestures). This intrapersonal synchrony (IaPS) is assumed to constitute interpersonal alignment. Gaze-gesture delays have been shown to be particularly enlarged and more variable in interactants with autism spectrum disorder (ASD) compared to non-autistic interactants. In the current study, we reversed the approach and mapped the measured behavior of interactants with and without ASD from a previous study onto virtual characters to study the effects of the differential communicative behavior on observers (N = 68), both with and without ASD (crossed design). During an interaction task with both characters, who indicated targets with gaze and delayed pointing gestures, we measured response times, gaze behavior, and post-hoc impression formation.Results show that character behavior indicative of ASD resulted in overall enlarged decoding times in observers and this effect was even pronounced in observers with ASD. A classification of observer’s gaze types indicated differentiated decoding strategies: Whereas non-autistic observers presented with a rather consistent eyes-focused strategy associated with efficient and fast responses, observers with ASD presented with highly variable decoding strategies. In contrast to communication efficiency, impression formation was not influenced by IaPS. The results underline the importance of timing differences in both production and perception processes during multimodal nonverbal communication in interactants with and without ASD. In essence, the current findings locate the manifestation of reduced reciprocity in autism not merely in the person, but in the interactional dynamics of dyads.

“…In the field of medical diagnosis [8,15,35,36,40,43,44], VR/AR plays a key role in the useful tool for the human-centered data acquisition. Researchers often build VR/AR scenes to collect human motion data to analyze and diagnose diseases.…”

“…There is a few virtual/augmented reality (VR/AR) research that shows the potential of usage in an interactive visualization. For example, Robles et al [35] proposed a VR system to support the screening of autism spectrum disorders. Pears et al [30] proposed several innovative AR solutions to deliver medical education.…”

“…Some authors proposed the effectiveness of new and especially immersive technology even for clinical intervention (Valentine et al, 2020;Robles et al, 2022). The term immersion describes a mediated experience in which the sense of mediation vanishes, and the experience feels as if being real (Biocca, 2002).…”

IntroductionDigital participation might have great potential for the everyday lives of individuals with Autism Spectrum Disorder (ASD). Previous research suggests that children with ASD enjoy and favor usage of digital technologies. As informative research on this topic is still sparse, this paper makes a contribution toward a better understanding of media usage in children with ASD.MethodsParents of 15 boys aged 6 to 11 diagnosed with ASD in Germany were asked about their children's media usage. For comparison, parents of 78 typically developing (TD) children were surveyed online.ResultsStatistical analyses reveal no differences between boys with and without ASD in media use, frequency, and reasons for use. However, there is a significant group difference in parents' perceptions of difficulty of restricting their child's media use: Parents of children with ASD reported greater difficulties of restriction of their child's media use than parents of TD children.DiscussionDigital media is an integral part of the daily lives of children with ASD and has the potential to increase the social inclusion of people with ASD through digital participation.
