fingerkomfort

Fingerkomfort is a term used in ergonomics and product design to describe the level of comfort and ease experienced by fingers during use or manipulation. It aggregates physical comfort, precision, and fatigue resistance, focusing on how design choices influence finger posture, grip, and tactile interaction. The concept is most common in German-speaking contexts and is applied to a wide range of devices and tools, from keyboards and mobile devices to hand tools and musical instruments.

Several factors contribute to fingerkomfort. The geometry of contact surfaces—edge radii, fillets, and curvature—affects pressure distribution and risk of discomfort. Material properties such as softness, springiness, and thermal feel influence how fingers perceive a surface. Actuation effort, travel distance, and required grip force determine how readily a task can be performed without strain. Texture, haptics, and feedback aid control. Temperature, moisture, and glove use can alter perceived comfort. Individual factors including hand size, age, and ergonomic health also play a role.

Evaluation combines subjective perception and objective measures. Participants may rate comfort after tasks, while sensors assess contact pressure, finger joint angles, grip strength, and fatigue. There is no single standard metric for fingerkomfort; practitioners typically use task- and user-specific criteria.

Applications span consumer electronics, tools, and medical devices, where increasing fingerkomfort can reduce user effort and error, and extend usability across populations.
