The World Health Organization stated that, based on studies conducted in the past 50 years, it is expected that there will be an increase in the prevalence of ASD globally, with estimation that one in every 160 children will have an ASD. It typically arises in early childhood, before the age of three years. Our review is useful to researchers in this field as it facilitates the comparison of existing studies with work currently being conducted, based on the availability of a wide range of studies in three different areas (AR, SG and PECS).ДЄutism Spectrum Disorder (ASD) is a neurodevelopment condition that affects many abilities including social, verbal and physical skills. Additionally, our systematic review also presents ongoing issues in this area of research and suggests promising future research directions. The studies scrutinized in our systematic review were examined to answer four primary and four sub-research questions, which we formulated to better understand general trends in the use of approaches for attracting people with ASD to behavioral therapies. We screened 1799 titles and abstracts, read, and retained 12 reviews and 43 studies.

Five databases were searched for keywords that may be included within the broad Autism Spectrum Disorder вЂASDвЂ™ umbrella term, alongside вЂaugmented realityвЂ™, вЂserious gamesвЂ™ and вЂPECSвЂ™. The aim of the current work is to efficiently examine systematic reviews and relevant primary studies on ASD solutions from 2015 to 2020, particularly those using the traditional Picture Exchange Communication System (PECS), the application of augmented reality and those that propose serious games, thereby providing an overview of existing evidence and to identify strategies for future research. To attract people with ASD who have communicative, social, emotional and attention deficit disorders to behavioral treatments, an attractive environment is needed that ensures continuity during treatment. For people with Autism Spectrum Disorder (ASD), using technological tools, such as augmented reality (AR) and serious games remain a new and unexplored option.
