Understanding how Humans perform Pressure Input on the Body

The skin is an increasingly popular surface for pressure-based input, but the input performance varies between locations on the body.This study investigated how anatomical differences affect the pressure interaction.In our first experiment, we measured maximum and comfortable force (MCF) in the forearm, the back of the hand, and the knuckle.In the second, we examine how target size and location influence input accuracy and control.We found that larger targets reduced task difficulty, while bony areas, such as the knuckle, supported more stable control than soft regions, such as the forearm.
