It is apparent that this is a method that will be used increasingly in the future, and it is imperative that meticulous research is conducted on the effects of the applications. The findings of these studies indicate that AAC systems are able to facilitate and enhance communication skills in children with ASD. Systematic review methodology was used to limit bias in the search of electronic databases, and relevant studies were selected, 20 of which met the inclusion criteria for the review. This review examines the research literature on the use of aided and unaided AAC systems in interventions for children with ASD, and investigates their effectiveness in enhancing language and communication skills in this population. The study results showed the importance of using TTS, STT, and CS features to enhance social and communication skills, as well as reduce social loneliness in adults with ASD.Ĭommunication deficits are one of the core symptoms of autism spectrum disorder (ASD), and augmentative and alternative communication (AAC) systems are utilized to facilitate the communication and language development of children with ASD. The developed app aims to support the inclusion and independent life of adults with ASD. This study discusses the potential for improving the communication skills of adults with ASD through special features in mobile messaging apps.
Lastly, we adopted grounded theory to analyze the interview data, and the following 5 categories emerged: app support, feature relevance, user interface design, overall feedback, and recommendations. Point-biserial correlation indicated that the SELSA-S rate of change was strongly related to usage of the TTS feature (r=0.708 P=.04) and CS feature (r=−0.917 P=.002), and moderately related to usage of the STT feature (r=0.428 P=.17). The Wilcoxon signed-rank test indicated that poststudy SELSA-S results were statistically significantly higher than prestudy results (z=−2.047 P=.04). The SELSA-S questionnaire results showed no change in the family subscale however, the social loneliness subscale showed a difference between prestudy and poststudy. Following the study, interviews were conducted with participants to discuss their experiences with the app. The Mobile Application Rating Scale: user version questionnaire was also used to evaluate the app’s usability. Additionally, 6 participants’ parents and 1 caregiver were asked to complete a short version of the Social and Emotional Loneliness Scale for Adults (SELSA-S) questionnaire to compare pre-post study results. Data logs of participants’ interactions with the app were collected. Seven adults with ASD participated in the study for a period of 10 to 16 weeks. Semistructured interviews were conducted with 5 experts working in fields related to ASD to help design the app.
We also hypothesized that usage of this app can reduce social loneliness in adults with ASD. We hypothesized that these accessibility features can enhance the social and communication skills of adults with ASD. This study aimed to investigate the effect of adding accessibility features, such as text-to-speech (TTS), speech-to-text (STT), and communication symbols (CS), to a messaging app (MAAN). Even though there are many techniques devised to enhance communication, these techniques are not considered in existing social media apps for people with ASD. For more than 30 years, specialists, parents, and caregivers have used techniques, such as applied behavioral analysis, augmentative and alternative communication, and the picture exchange communication system to support the social and communication skills of people with ASD. Individuals with autism spectrum disorder (ASD) often exhibit difficulties in social and communication skills.
