In this article we argue for an interdisciplinary approach to designing interactive technology for young children on the Autistic Spectrum. We believe it key for the design process to embrace perspectives from diverse fields to arrive at a methodology, and consequently technology, that delivers satisfactory outcomes for all stakeholders involved. The ECHOES project has provided us with the opportunity to work on a technology-enhanced learning environment that supports acquisition and exploration of social skills by typically developing children and children with high-functioning autism and Asperger Syndrome. ECHOES' research methodology and the learning environment relies crucially on multi-disciplinary expertise including developmental and clinical psychology, visual arts, human-computer interaction, artificial intelligence, education and many other cognate disciplines. In this article, we reflect on the methods needed to develop a technology-enhanced learning environment for young users with Autism Spectrum Disorder. We identify key benefits, challenges and limitations of this approach. Although the context of ECHOES is very specific, we believe that there are a number of guidelines for the desing of technology-enhanced intervention for autism that can benefit a wider community of researchers in this emerging discipline.

Autism can be understood as a concealable stigmatised identity. This is the first systematic review to synthesise the literature on autistic people's experiences of stigma and coping strategies. 2877 studies were screened and 27 were included in this review. The reviewed literature demonstrates that autistic individuals are acutely aware of being stereotyped, judged, and discriminated by others. Autistic people also show signs of internalising stigma, rendering them more vulnerable to low self-worth and poorer mental health. To manage the impact of stigma, the included studies suggest that autistic individuals may use these strategies: concealment and camouflaging, selective disclosure and self-advocacy, as well as positive reframing and reconstructing identity. However, the evidence is limited and mixed in terms of how helpful and effective these strategies are. Future studies should include autistic populations with a wider range of intellectual abilities and explore interventions that can support autistic people in managing stigma to supplement interventions that seek to reduce stigma towards autistic people. The power of language in perpetuating and challenging stigma also has important implications for research and practice, underscoring the need for researchers and practitioners to reflect carefully on the messages they are communicating about autism. Lay summaryThis review has found that autistic people often experience stigma, which refers to negative attitudes and treatment from others. Because of that, some autistic people also have negative beliefs about themselves, which may affect their self-worth and mental health.While research suggests that autistic people use a range of strategies to manage stigma, the evidence is limited and mixed in terms of how helpful these strategies are.

This paper presents an evaluation of the societal impact of a simulation-based Serious Game. FloodSim was developed with the aim of raising awareness of issues surrounding flooding policy and citizen engagement in the UK. The game was played by a large number of users (N=25,701) in a period of 4 weeks. Quantitative and qualitative analyses (on a reduced data set) were carried out in order to explore the impact of FloodSim play in raising the general public awareness around flooding in the UK. The results suggest FloodSim was hugely successful in generating general public interest and there was evidence that (a) FloodSim increased awareness at a basic level and (b) that despite the simplicity of the simulation, players perceived FloodSim to be an accurate source of information about flood risk and prevention. This suggests that serious games such as FloodSim have potential to engage the public and raise awareness of societal issues. However, FloodSim only raised awareness at a basic level. It is suggested that more needs to be done to endow serious games with pedagogical principles and more care should be given to the accuracy of the information they convey. The appropriateness of games as an educational medium for raising awareness of complex, real-life issues should also be carefully considered. This study throws some light on the potential of simulation-based Serious Games to offer experiential learning, engage users with serious topics while raising public awareness and understanding of social issues such as flooding and related policymaking. Future research is outlined consisting of identifying the problems and challenges in designing and developing serious games while considering pedagogical principles.

Children with ASD have difficulty with social communication, particularly joint attention. Interaction in a virtual environment (VE) may be a means for both understanding these difficulties and addressing them. It is first necessary to discover how this population interacts with virtual characters, and whether they can follow joint attention cues in a VE. This paper describes a study in which 32 children with ASD used the ECHOES VE to assist a virtual character in selecting objects by following the character's gaze and/or pointing. Both accuracy and reaction time data suggest that children were able to successfully complete the task, and qualitative data further suggests that most children perceived the character as an intentional being with relevant, mutually directed behaviour.

This article examines the educational efficacy of a learning environment in which children diagnosed with Autism Spectrum Conditions (ASC) engage in social interactions with an artificially intelligent (AI) virtual agent and where a human practitioner acts in support of the interactions. A multi-site intervention study in schools across the UK was conducted with 29 children with ASC and learning difficulties, aged 4-14 years old. For reasons related to data completeness and amount of exposure to the AI environment, data for 15 children was included in the analysis. The analysis revealed a significant increase in the proportion of social responses made by ASC children to human practitioners. The number of initiations made to human practitioners and to the virtual agent by the ASC children also increased numerically over the course of the sessions. However, due to large individual differences within the ASC group, this did not reach significance. Although no evidence of transfer to the real-world post-test was shown, anecdotal evidence of classroom transfer was reported. The work presented in this article offers an important contribution to the growing body of research in the context of AI technology design and use for autism intervention in real school contexts. Specifically, the work highlights key methodological challenges and opportunities in this area by leveraging interdisciplinary insights in a way that (i) bridges between educational interventions and intelligent technology design practices, (ii) considers the design of technology as well as the design of its use (context and procedures) on par with one another, and (iii) includes design contributions from different stakeholders, including children with and without ASC diagnosis, educational practitioners, and researchers.
