This study examined the use of TATOO (Danial-Saad & Chiari, 2017) to assess motor skills in touchscreen operation among 120 adults with intellectual and developmental disabilities (hereinafter: IDD) aged 21 and over. The study focused on adapting TATOO’s user interface (UI) and examining its feasibility for this population. The findings showed a significant correlation between the IDD level, the age, user experience and the participants’ performance. TATOO demonstrated concurrent and discriminant validity compared to standardized tests and was found to provide detailed information about specific motor abilities required when operating touchscreen. The findings indicate the importance of adapting touch interfaces to the specific needs of people with IDD, and emphasizes TATOO’s potential to support professionals in making devices accessible to this population. Such accessibility opens opportunities for equal integration into society, work and daily life, helping overcome barriers and improve quality of life. Additionally, the findings suggest directions for future research and practical applications.
