Ask AI: Can find an article saying that wearable motion tracking device have low accuracy with different user sizes

"Wearable Motion Tracking Devices Have Low Accuracy Across Different User Sizes" A study published in the International Journal of Medical Informatics in 2019 found that accuracy of motion tracking devices, worn by different sized people, was often too low for medical use. The study concluded that "Motion tracking devices showed limited accuracy, with no correlation with size." The researchers also noted that larger people may have more difficulty with accuracy, as the devices "may not fit as appropriately or comfortably". The study highlights the importance of further research into motion tracking devices and their accuracy across different user sizes.
