This application requests equipment to quantitatively and automatically calculate kinematic variations during working activities over a typical working period (normally a working day). Musculoskeletal disorders (MSDs) are principally a function of motion, posture and repetition, as well as psychosocial stresses. Recent research has shown that even highly skilled operators include variations in their gestures which can moderate MSD risk. It is important that models account for the real posture and motion variations employed by workers. A three-camera video-based and frequency-variable SIMI motion system is requested to support this important research, along with eight wireless 2D inclinometers (for the back, upper arms, forarms and hands) which do not require visual contact and interface with the CAPTIV L7000 analysis system. These will complement traditional video equipment and analysis tools already available: CAPTIV L2100 software to time-analyse observed video qualitatively (but not quantitatively capture angular variations) and CAPTIV L3000 with force sensing technologies (linear tension-compression transducer, finger-tip sized force-sensing resistors). VICON or OPTOTRAK systems at institutions 2 to 3 hours drive away remain of interest for controlled laboratory studies, unlike the work-centred studies proposed here. With the requested equipment, quantitative and exact data analysis recorded can be recorded either in a work-site or in a laboratory.

该应用要求设备在典型的工作时间段（通常是工作日）内定量和自动地计算工作活动期间的运动学变化。 肌肉骨骼疾病（MSD）主要是运动，姿势和重复以及心理社会压力的功能。最近的研究表明，即使是高度熟练的操作员，也会在他们的手势中加入一些变化，这些变化可以降低MSD的风险。 重要的是，模型考虑到工人所采用的真实的姿势和运动变化。 一个三摄像头视频为基础的和变频SIMI运动系统需要支持这一重要的研究，沿着8个无线二维倾角仪（背部，上臂，前臂和手），不需要视觉接触和接口的CAPTIV L7000分析系统。 这些将补充现有的传统视频设备和分析工具：CAPTIV L2100软件，用于对观察到的视频进行定性时间分析（但不定量捕获角度变化），CAPTIV L3000具有力感测技术（线性拉伸-压缩传感器，指尖大小的力感测电阻器）。 与本文提出的以工作为中心的研究不同，在2至3小时车程的机构中使用VICON或OPTOTRAK系统仍然是受控实验室研究的兴趣所在。 使用所需的设备，可以在工作现场或实验室中记录定量且准确的数据分析。
