Abstract

The spread, in sport, of technologies able to detect and organize in real time a wide range of data related to the athlete and the context (tracker, gps, gyroscopes, accelerometers, bio-sensors embedded in smartphones or available as wearable devices) offers a great opportunity to collect performance data, allowing objective, accurate and non-invasive physical activity monitoring. In particular, this type of detection allows to avoid all the interferences connected to the laboratory settings. Wearable devices using textiles with embedded physiological sensors are used in various applications involving monitoring, control and learning» (Helmer et al., 2010). In sport, wearable technologies allow detections that do not alter the "natural" scenario of the performance. This work presents the design and development of a wearable device for the collection of data relating to a fundamental of volleyball: the service. The device consists of a glove, wearable by the athlete, equipped with various ultra-thin sensors (such as not to affect performance). The sensors are operated by an Arduino Nano microcontroller, worn at the forearm level by an arm band. The basic sensor is a flexible and ultra-thin TekScan pressure sensor (<0.1 mm), able to detect the pressure exerted by the hand on the ball in a range between 0 and 100 kg with an accuracy of 100g and a sampling frequency of 100 Hz. Collected data are processed by a specially developed support software that provides elementary statistics and specific graphical representations and can be exported in the most common formats.
powerlove:一种可穿戴技术的起源,旨在研究排球发球
在体育运动中,能够实时检测和组织与运动员和环境相关的各种数据的技术(跟踪器、gps、陀螺仪、加速度计、嵌入智能手机或可穿戴设备的生物传感器)的普及为收集表现数据提供了很好的机会,从而实现客观、准确和非侵入性的身体活动监测。特别是,这种类型的检测可以避免与实验室设置相关的所有干扰。使用带有嵌入式生理传感器的纺织品的可穿戴设备用于涉及监测、控制和学习的各种应用»(Helmer et al., 2010)。在体育运动中,可穿戴技术允许在不改变比赛“自然”场景的情况下进行检测。这项工作展示了一种可穿戴设备的设计和开发,用于收集与排球基础相关的数据:服务。该设备由一个手套组成,由运动员佩戴,配备各种超薄传感器(如不影响成绩)。传感器由Arduino纳米微控制器操作,通过臂带佩戴在前臂水平。基本传感器是一个灵活的超薄TekScan压力传感器(<0.1 mm),能够检测手对球施加的压力,范围在0到100 kg之间,精度为100g,采样频率为100hz。收集的数据由专门开发的支持软件处理,该软件提供基本统计数据和具体的图形表示,并可以最常用的格式输出。
