In recent years, the development of mobile applications for people within the autism spectrum has proliferated to help enhance skills that could be diminished in users with this condition. However, the usability of these applications does not appear to be the focus of development because users with autism can have difficulty with fine motor skills. This article focuses on evaluating the optimal drag distance and the sizes of the interaction elements for users with Autism Spectrum Disorder. To accomplish this goal, a case study was conducted that involved 20 users with Autism Spectrum Disorder and 30 users with typical development, using a prototype generated and two applications for commercial use on 7-in. tablets. For both developed applications, a slight variation can be observed between the different groups of participants. In the interaction with Proyect@ Habilidades, the application has pictograms of 65 pixels and it has a maximum trailing distance of 340 pixels. Moreover, in Proyect@ Retratos, where there is a minimum deviation between users with levels of autism 1 and 2, it also has pictograms of 65 pixels but with a drag distance of 110 pixels. For this reason, according to the results, we suggest that in order to obtain better results in the interaction with applications aimed at users diagnosed with autism spectrum disorders, the applications should have pictograms of a range of 65 pixels with a drag interaction between 110 and 340 pixels. Considering in context a 7-in. tablet with a resolution of 1280 × 800 pixels.
近年来，为了帮助自闭症谱系障碍患者增强技能，针对该人群的移动应用程序蓬勃发展。然而，这些应用程序的可用性似乎并不是开发的重点，因为自闭症患者可能存在精细运动技能障碍。本文专注于评估自闭症谱系障碍患者的最佳拖动距离和交互元素大小。为了实现这一目标，进行了一项案例研究，涉及 20 名自闭症谱系障碍患者和 30 名具有典型发育的参与者，使用在 7 英寸平板电脑上生成的原型和两个商业应用程序。对于这两个开发的应用程序，可以观察到不同组别的参与者之间存在细微差异。在与 Proyect@ Habilidades 的交互中，应用程序有 65 像素的图标，最大拖动距离为 340 像素。此外，在 Proyect@ Retratos 中，自闭症 1 级和 2 级的用户之间的偏差最小，它也有 65 像素的图标，但拖动距离为 110 像素。因此，根据结果，我们建议为了在与针对自闭症谱系障碍患者的应用程序交互中获得更好的效果，应用程序应该具有 65 像素范围内的图标，拖动交互距离应为 110 到 340 像素。考虑到分辨率为 1280 × 800 像素的 7 英寸平板电脑。
