The aim of the present work is to introduce a novel wearable device suitable to be used to investigate perception in interactive tasks, on individuals with and without sensory disabilities. The system is composed by small units embedded with sensors and actuators that allows emitting different kind of stimuli (light, haptic, sound) and to record the user response, thanks to a capacitive sensor. We validated the system by implementing an interception task in three different sensory modalities: visual, tactile and auditory. Six subjects with normal sight were asked to tap either a static or a moving stimulus generated by 6 units placed on their forearm. Results suggest that the system can effectively provide new insights in characterizing how perception principles vary when perceptual judgement occurs through different senses. This confirms the device potential in contributing to the design of rehabilitation protocols rooted on neuroscientific findings, for people with sensory impairments.
本研究的目的是介绍一种新型可穿戴设备，适用于在有或没有感官障碍的个体中，用于研究交互任务中的感知。该系统由嵌入传感器和执行器的小单元组成，借助电容式传感器，该系统能够发出不同类型的刺激（光、触觉、声音）并记录用户反应。我们通过在视觉、触觉和听觉三种不同感官模式下实施拦截任务来验证该系统。六名视力正常的受试者被要求点击放置在他们前臂上的6个单元产生的静态或动态刺激。结果表明，该系统可以有效地提供新的见解，以表征当通过不同感官进行感知判断时，感知原理是如何变化的。这证实了该设备在为基于神经科学发现的康复方案设计做出贡献方面的潜力，适用于有感官障碍的人群。
