Down syndrome causes a reduction in cognitive abilities, with visual-motor skills being particularly affected. In this work, we have focused on this skill in order to stimulate better learning. The proposal relies on stimulating the cognitive visual-motor skills of individuals with Down Syndrome (DS) using exercises with a gestural interaction platform based on the KINECT sensor named TANGO:H, the goal being to improve them. To validate the proposal, an experimental single-case study method was designed using two groups: a control group and an experimental one, with similar cognitive ages. Didactic exercises were provided to the experimental group using visual cognitive stimulation. These exercises were created on the TANGO:H Designer, a platform that was designed for gestural interaction using the KINECT sensor. As a result, TANGO:H allows for visual-motor cognitive stimulation through the movement of hands, arms, feet and head. The "Illinois Test of Psycholinguistic Abilities (ITPA)" was applied to both groups as a pre-test and post-test in its four reference sections: visual comprehension, visual-motor sequential memory, visual association, and visual integration. Two checks were made, one using the longitudinal comparison of the pre-test/post-test of the experimental group, and another that relied on comparing the difference of the means of the pre-test/post-test. We also used an observational methodology for the working sessions from the experimental group. Although the statistical results do not show significant differences between the two groups, the results of the observations exhibited an improvement in visual-motor cognitive skills.
唐氏综合征会导致认知能力下降，其中视觉运动技能受影响尤为明显。在这项工作中，我们专注于这项技能，以刺激更好的学习。该提案依赖于使用基于 KINECT 传感器的手势交互平台 TANGO:H 来刺激唐氏综合征（DS）患者的认知视觉运动技能，目标是提高他们的技能。为了验证该提案，设计了一个使用两个具有相似认知年龄的组（对照组和实验组）的单案例实验研究方法。实验组使用视觉认知刺激提供了教学练习。这些练习是在 TANGO:H Designer 上创建的，该平台是专为使用 KINECT 传感器进行手势交互而设计的。因此，TANGO:H 允许通过手部、手臂、脚部和头部的运动进行视觉运动认知刺激。对两组都应用了“伊利诺伊心理语言能力测试（ITPA）”，作为其四个参考部分（视觉理解、视觉运动顺序记忆、视觉联想和视觉综合）的前测和后测。进行了两次检查，一次是使用实验组的前测/后测的纵向比较，另一次是依赖于比较前测/后测的均值差异。我们还对实验组的工作会话使用了观察方法。尽管统计结果显示两组之间没有显著差异，但观察结果表明视觉运动认知技能有所提高。
