Researchers have developed an enhanced wearable motion-tracking system that could improve the accuracy of fitness trackers used to monitor exercise and training. The team provides details in the International Journal of Data Mining and Bioinformatics.
Current wearable devices often show inconsistencies in heart-rate monitoring and can miscalculate calories burnt, speed, and distance travelled. Such inaccuracies limit their usefulness for health-conscious consumers, but particularly for athletes and their coaches who need precision.
The new work hopes to improve both data collection and sensor calibration. Researchers used fuzzy algorithms, computational methods designed to handle uncertain or variable information, to analyse real-time exercise data. They also applied filtering techniques to remove noise and improve data quality before calibrating the device’s sensors.
In their tests, they found that measurements of heart rate, calorie expenditure, movement speed, and distance closely matched those obtained through standard laboratory procedures. The researchers suggest that their main advance lies in combining improved sensor calibration with more sophisticated data processing. This allows the device to generate a more reliable picture of an athlete’s training performance in real time.
The findings could be used beyond competitive sport to help users develop personalised fitness programmes for health monitoring and injury prevention by giving them more dependable information about their physical activity.
