In this paper we present the SPRF (Sensorised Pen with Real time Feedback) platform that aims to objectively detect handwriting-related graphomotor disorders in children with Special Educational Needs (SEN), and to treat them through game-guided intervention plans performed with the same sensorised system. We have developed two sensorised devices (wristband and pen) for the SPRF to be able to quantify relevant physical parameters as children perform both diagnostic activities and the subsequent intervention plans. This way, SPRF differentiates from traditional methodologies commonly adopted in non-technologically assisted approaches where well-known graphomotor variables (directly related to the abovementioned physical parameters) are observed by diverse professionals with different criteria, which undoubtedly leads to an undesirable subjectivity. The novelty of SPRF relates to: (i) the ability to suggest tailored intervention plans for each child, based on objective parameter measurement, and (ii) the possibility to instantaneously correct children as they perform that custom-made plan thanks to an intuitive interface (similar to traffic lights) through which therapists can easily identify skills achieved, in progress or failed. The approach has been validated with a real group of SEN children from Ecuador, showing that, in terms of graphomotor skills, children who received on-the-fly feedback during the therapeutic intervention outperformed children not exposed to such real-time corrections.

自动反馈教育平台：特殊教育需求儿童写作学习的评估和治疗干预

在本文中，我们提出了 SPRF（实时反馈传感笔）平台，旨在客观地检测有特殊教育需要 (SEN) 的儿童中与手写相关的书写运动障碍，并通过使用该平台执行的游戏引导干预计划来治疗他们传感系统。我们为 SPRF 开发了两种传感设备（腕带和笔），以便能够在儿童执行诊断活动和后续干预计划时量化相关的物理参数。这样，SPRF就有别于非技术辅助方法中常用的传统方法，在非技术辅助方法中，众所周知的书写运动变量（与上述物理参数直接相关）是由不同的专业人士以不同的标准观察的，这无疑会导致不良的主观性。 SPRF 的新颖之处在于：（i）能够根据客观参数测量为每个孩子建议量身定制的干预计划，以及（ii）通过直观的界面，可以在儿童执行定制计划时立即纠正他们（类似于交通信号灯）治疗师可以通过它轻松识别已实现、正在进行或失败的技能。该方法已在来自厄瓜多尔的一组真实的 SEN 儿童中得到验证，结果表明，就书写运动技能而言，在治疗干预期间收到即时反馈的儿童表现优于未接受此类实时纠正的儿童。
