Human Factors & Physiology 🧤 in medical devices ⚕️and wearables
Accuracy, acceptance, and comfort are key for health-related devices. Smart contact lenses, launched to monitor glucose levels in the tears, were withdrawn from the market due to a low accuracy and acceptance. At the same time, the ŌURA ring ⭕ made its way on many fingers providing heart rate measurements as accurate as an ECG.
The ŌURA Ring gained strong user acceptance by using a lightweight titanium design that feels like a normal ring while providing continuous heart rate 💓, sleep, and activity data through a simple app interface. Many users report wearing it daily without discomfort, which contributed to its rapid adoption among health-conscious consumers.
Non-invasive procedures whenever possible and the right balance between possible sensory discomforts and gains from the product usage, are fondational blocks for successful medical devices and gears.
This is why at DervalResearch we apply Human Factors & Physiology 🧤 to help organizations improve user acceptance and real-world performance of medical devices and wearables.
Illustrated below is a before/after implementation case combating burnout with non-invasive preventive solutions (like the ŌURA Ring) replacing Band-Aid solutions (like energy drinks). You can find more examples of Human Factors & Physiology applied to various industries on our website.
