本文描述了一种评估儿童空间认知发展的跨学科方法，重点是技术。提出了一种仪器玩具（积木盒），其中嵌入了用于方向跟踪的磁惯性传感器，专门开发用于评估将物体插入孔中的能力。功能规格源自神经科学家设计的用于评估儿童空间认知技能的实验方案。技术选择强调生态要求。提出了适合非结构化环境的临时校准程序。基于在日托中心对典型发育儿童（12-36 个月大）进行的实验试验的初步结果表明，如何以半自动方式（即独立于评估者）有效地使用仪器化物体来获得准确的测量结果，例如与物体插入任务相关的方向误差和插入时间。这项研究表明，对儿童空间认知进行生态评估的技术方法确实可行，并且可能有助于识别和早期评估发育迟缓。
This paper describes an interdisciplinary approach to the assessment of children development of spatial cognition, with a focus on the technology. An instrumented toy (block-box) is presented which embeds magneto-inertial sensors for orientation tracking, specifically developed to assess the ability to insert objects into holes. The functional specifications are derived from experimental protocols devised by neuroscientists to assess spatial cognition skills in children. Technological choices are emphasized with respect to ecological requirements. Ad-hoc calibration procedures are presented which are suitable to unstructured environments. Preliminary results based on experimental trials carried out at a day-care on typically developing children (12–36 months old) show how the instrumented objects can be used effectively in a semi-automatic fashion (i.e., rater-independent) to derive accurate measurements such as orientation errors and insertion time which are relevant to the object insertion task. This study indicates that a technological approach to ecological assessment of spatial cognition in children is indeed feasible and maybe useful for identification and early assessment of developmental delay.
