The Effect of Pressure Levels on Comfort in Ankle Wearable Devices: A Human-Centered Ergonomics Approach

Abstract: This study investigates the relationship between pressure levels and user comfort in ankle wearable devices, with a focus on the interplay between pressure levels and individual physiological characteristics. A two-phase experimental design was employed, including a preliminary study to determine pressure thresholds and a formal experiment to evaluate comfort under various pressure levels (350g–750g). Using modified evaluation tools tailored for lower limb devices, we examined nine dimensions of comfort through subjective rating scales. The results revealed that comfort responses to pressure levels exhibit non-linear trends, with specific pressure ranges optimizing attachment and lightness, while others induce discomfort and restricted mobility. Individual factors such as BMI and lower leg circumference were found to significantly modulate these effects, underscoring the necessity of personalized designs for wearable devices. This study provides methodological advancements in comfort assessment and offers actionable insights for optimizing wearable device design in healthcare and rehabilitation applications.
