Why Human Factors Matter Accuracy alone does not determine whether a physiological monitoring device performs well in real-world use. Human factors studies evaluate how users interact with a device during normal operation. They confirm that the device can be used correctly and repeatedly under the conditions reflected in its claims. For medical device manufacturers, this work strengthens the evidence package by showing that performance is achievable under realistic workflo

“Usability testing of wearable medical device in a clinical trial" Introduction: Usability as a Core Component of Clinical Success The proliferation of wearable medical devices—from continuous glucose monitors to smart ECG patches and pulse oximeters—has transformed healthcare. These devices promise real-time health monitoring, greater patient autonomy, and continuous data collection. However, their effectiveness in real-world settings hinges not only on technical accuracy bu
