面向ASD儿童的交互式工作记忆训练系统

Design of interactive working memory system for children with ASD

孤独症谱系障碍个体存在工作记忆加工缺陷,而这种工作记忆加工缺陷可以通过训练来改善。现在已经有一些针对ASD儿童的工作记忆训练系统,但存在缺陷:不方便携带,儿童需要直接与电子产品接触。本系统旨在训练ASD儿童的工作记忆能力,系统克服了之前此类训练系统的缺陷,其特点之一是便于携带,只要有无线网络,可随时随地对ASD儿童进行干预和训练,其特点之二是交互式,即不需要儿童直接接触电子产品,而是直接对实物进行操作,符合孤独症谱系障碍儿童的身心发展特点。移动终端的普及、图像处理和计算机视觉算法的发展尤其是开源视频处理库OpenCV的发展以及成熟,为开发这款基于Android平台的交互式工作记忆训练系统提供了技术支持。通过测试,验证了该方案的可行性。

Individuals with autism spectrum disorders （ASD） have working memory defects and the working memory ability can be improved through training. There are some working memory training systems for ASD children but with some defects in it. This system is designed to train the working memory of children with ASD overcoming the defects of such training systems before. One of the characteristics of this system is easy to carry. As long as with wireless network, it can be used to train children with ASD whenever and wherever possible. Interactive operation is the other characteristic of this system which does not ask the the children to contact with electronic products directly, but the material objects instead. The system fit the characteristics of physical and mental development of children with ASD. The popularization of the mobile terminal and the development of computer vision and image processing algorithm, especially the development and maturity of open source computer vision library （OpenCV） are the technology supports for the development of this system.
