Adaptive technological interventions for autism spectrum disorder: a literature review

Individuals with autistic spectrum disorder are often described as having communication, social, emo-tional, and behavioral impairments. They are often isolated and passive, with few opportunities for positive and constructive interaction with the outside world. Moreover, they may exhibit withdrawn, stereotyped and disruptive behaviors. The aforementioned conditions can seriously hamper their ability to adapt to the environment, with negative consequences on their quality of life. Phenotypic heterogeneity and manifestation, as well as symptom severity, can vary greatly from child to child. These determine the need for individualized and adaptive interventions according to specific needs, including factors such as age, intellectual ability, and specific affected areas. Early intervention would promote adaptive skills, self-determination, and autonomy towards the environment. However, wait times and costs do not allow for early assessment, and therefore intervention times are delayed, affecting the quality of life of children and parents. In addition, traditional intervention programs depend on the expertise of the therapists. One possible way to overcome this problem is by using objective adaptive technologies based on needs. This article aims to provide an overview of the empirical evidence available over the past seven years. Overall, 8 studies were selected, with 132 participants using 4 technological systems. Finally, the technological, clinical, psychological, and rehabilitative implications of the findings are discussed. Practical guidelines within this topic area are outlined as future research perspectives.
