AI总结:

本研究提出基于儿童-计算机交互的年龄组检测方法,通过分析儿童与移动设备交互的时间序列,结合序列选择与分类算法,实现超85%的准确率,优于现有方法,可支撑适配年龄的儿童技术应用开发。

摘要:

本文提出了一种新颖的儿童-计算机交互(Children-Computer Interaction,CCI)方法,用于年龄组检测任务。该方法聚焦于对儿童与移动设备交互过程中生成的时间序列进行自动分析。具体而言,我们从大规模公开数据库ChildCIdb中的一项特定测试——儿童使用触控笔平板为树木涂色的任务中,提取了25个与儿童交互的空间、压力及运动学信息相关的时间序列。\n 我们采用不同的时间序列选择技术对所提方法开展了全面分析,以筛选出对年龄组检测任务最具判别力的序列:其一为统计分析,其二为名为序列前向搜索(Sequential Forward Search,SFS)的自动算法。此外,本文还研究了动态时间规整重心平均(Dynamic Time Warping Barycenter Averaging,DBA)、隐马尔可夫模型(Hidden Markov Models,HMM)等不同分类算法。实验取得了超过85%的准确率,优于现有文献中的方法,且是在更具挑战性的年龄组条件下实现的。最后,本研究提出的方法可惠及众多儿童相关应用,例如助力构建适配年龄的技术环境。

英文摘要:

This article proposes a novel Children-Computer Interaction (CCI) approach for the task of age group detection. This approach focuses on the automatic analysis of the time series generated from the interaction of the children with mobile devices. In particular, we extract a set of 25 time series related to spatial, pressure, and kinematic information of the children interaction while colouring a tree through a pen stylus tablet, a specific test from the large-scale public ChildCIdb database. A complete analysis of the proposed approach is carried out using different time series selection techniques to choose the most discriminative ones for the age group detection task: i) a statistical analysis, and ii) an automatic algorithm called Sequential Forward Search (SFS). In addition, different classification algorithms such as Dynamic Time Warping Barycenter Averaging (DBA) and Hidden Markov Models (HMM) are studied. Accuracy results over 85% are achieved, outperforming previous approaches in the literature and in more challenging age group conditions. Finally, the approach presented in this study can benefit many children-related applications, for example, towards an age-appropriate environment with the technology.
