Autism is a neurodevelopmental disorder with deficits in communication, social interaction, and restricted and repetitive patterns of behavior. Due to these restrictions, one can cite the literacy process as a learning problem for people with autism. Although psychological interventions have been used to mitigate this problem, technology plays an essential role in this public. Recent studies show that children with autism demonstrate interest and best performance results when in contact with technology. Nevertheless, it is still a challenge to find studies that gather technological approaches to help the improvement of literacy skills. Based on this premise, this work focus on identifying technological approaches used to aid in the literacy process of children with autism. To achieve our goal, we conducted a systematic mapping where six studies were analyzed to answer our research questions. We identified several computational contributions, like software, desktop, and web applications that benefit the enhancement of the learning process of children with autism.
