We present WEARDA, the open source WEARable sensor Data Acquisition software package. WEARDA facilitates the acquisition of human activity data with smartwatches and is primarily aimed at researchers who require transparency, full control, and access to raw sensor data. It provides functionality to simultaneously record raw data from four sensors -- tri-axis accelerometer, tri-axis gyroscope, barometer, and GPS -- which should enable researchers to, for example, estimate energy expenditure and mine movement trajectories. A Samsung smartwatch running the Tizen OS was chosen because of 1) the required functionalities of the smartwatch software API, 2) the availability of software development tools and accessible documentation, 3) having the required sensors, and 4) the requirements on case design for acceptance by the target user group. WEARDA addresses five practical challenges concerning preparation, measurement, logistics, privacy preservation, and reproducibility to ensure efficient and errorless data collection. The software package was initially created for the project ``Dementia back at the heart of the community'', and has been successfully used in that context.
翻译:我们介绍了WEARDA(开放源码WEARDA),这是开放源码WEARDA(WEARDA)的传感器数据采集软件包。WEARDA(WEARDA)协助以智能观察器获取人类活动数据,主要针对需要透明度、全面控制和原始传感器数据的研究人员。它提供功能,同时记录来自四个传感器的原始数据 -- -- 三轴加速计、三轴陀螺仪、气压计和全球定位系统 -- -- 这应该使研究人员能够估计能源支出和地雷移动轨迹。一个运行TizenOS的三星智能监视器之所以被选中,是因为:(1)智能观察软件API所需的功能;(2)软件开发工具和无障碍文件的可用性;(3)具有所需的传感器;(4)关于案件设计的要求,供目标用户群体接受。WEARDA处理五个实际挑战,涉及准备、测量、物流、隐私保护以及推广,以确保高效和无误差数据收集。软件包最初是为社区核心的“Deritia”项目创建的,并在此范围内成功使用。</s>
