This research examined the usability of an interactive mobile application (tablet application) designed to teach daily living skills to individuals with intellectual disabilities (ID). Effectiveness, efficiency, and satisfaction aspects were investigated. The persistence of a newly learned skill, operating a vacuum cleaner, was assessed following training sessions. The study also examined how well participants generalized the skill to a different tool and setting after learning via the interactive tablet application. In addition, to determine the social validity of the study, five special education teachers’ views (satisfaction levels) about the tablet application were examined. To determine the efficiency of the tablet application, differences in time of intervention sessions between the pilot study and the main study were investigated. A single-case research methodology was employed with a multiple baseline design. Furthermore, to identify the usability issues of educational tablet applications, heuristic evaluation and user test methods were used together. One male and four females with a diagnosis of intellectual disability took part in the study. All participants improved their ability to use the vacuum cleaner and performed the skill correctly following the intervention sessions. Performance during generalization and maintenance sessions also met defined success criteria. Efficiency data show that changes in the tablet application decrease the significant amount of time spent for intervention. It is an important result for individuals with ID who might not be able to focus attention over a longer period of time. The results of this study show that using the interactive tablet applications in the education of individuals with ID is an effective method for improving their daily living skills.

针对智障人士的教育移动应用程序的可用性调查

这项研究检查了旨在向智障人士（ID）教授日常生活技能的交互式移动应用程序（平板电脑应用程序）的可用性。有效性，效率和满意度方面进行了调查。在培训课程之后，评估了吸尘器操作的一项新技能的持久性。该研究还检查了参与者在通过交互式平板电脑应用程序学习后将技能广泛推广到其他工具和设置的程度。此外，为了确定研究的社会有效性，研究了五名特殊教育教师对平板电脑应用的看法（满意度）。为了确定片剂应用的效率，调查了初步研究和主要研究之间的干预时间差异。采用单案例研究方法和多个基线设计。此外，为了确定教育平板电脑应用程序的可用性问题，将启发式评估和用户测试方法一起使用。被诊断患有智力障碍的一男四女。所有参与者都提高了使用真空吸尘器的能力，并在干预课程之后正确地执行了该技能。泛化和维护会议期间的性能也达到了定义的成功标准。效率数据显示，平板电脑应用程序的更改减少了干预所花费的大量时间。对于具有ID的个人而言，这可能是一个重要的结果，他们可能无法长时间集中注意力。
