N^o 6 – Geometry Matters

“A multi-point system can provide perspective on different risk types and different body segments,” Join LifeBooster’s Program Manager & Ergonomist, William Thomas, as we discuss why geometry matters when using multi-point sensors to collect and assess risk data. 

Single-Point Sensors Capture Data From a Single Joint

Wearable technologies are becoming increasingly present in Health & Safety programs. Many companies now rely on wearables to expand the capabilities of their safety teams. These safety tools offer different methods of capturing risk data, as well as differing degrees of the breadth, depth, and quality of the data collection & analysis. Single-point and multi-point sensor systems are common options in-market today but they offer different values to their users. Single-point systems provide perspective on movement at a single joint and are often used in behavior intervention projects to improve the postures of a single movement pattern. Single-point systems are limited in their ability to measure, analyze and represent dynamic kinematic data on complex, multi-joint movements. Multi-point sensor systems on the other hand deliver a much more robust analysis of risk.

Multi-Point Sensors Provide Dynamic 3D Movement Mapping

Many validated risk standards & assessments require measurement and analysis of multi-joint segments and of joint segments in relation to others. In other words, geometry matters in conducting accurate ergonomic assessments. A multi-point system can provide perspective on both different risk types and different body segments. This enables the application of standardized risk tools through a truly digitized risk assessment process. The net benefit is a powerful system for accurately analyzing and reproducing kinematic data and for assessing risk using standardized tools for repetitive motions and postures.

Multi-Point Sensors Analyze Multiple Body Segments and Risk Factors

People come in different shapes and sizes, we have different strengths, weaknesses, and skills, and are not exposed to risk uniformly. Because of this the risk profile for every employee, even those performing the same job task, is unique. To accurately measure, map, and analyze complex employee movements, the utilization of a multi-point IMU sensor system is necessary. A multi-point sensor system accounts for these variabilities and enables dynamic movement mapping. A multi-point sensor system coupled with an extensible risk analytics platform that can combine data from multiple sensors delivers rapid analysis of risk from the very first assessment. These multi-point systems can enable all-in-one assessments, that is to say, the analysis of multiple risk types including repetitive motion, posture, vibration, and thermal stress, simultaneously. Providing you with a more comprehensive, accurate perspective on the different risks facing your employees.
