This paper investigates the versatility of force feedback (FF) technology in enhancing user interfaces across a spectrum of applications. We delve into the human finger pad’s sensitivity to FF stimuli, which is critical to the development of intuitive and responsive controls in sectors such as medicine, where precision is paramount, and entertainment, where immersive experiences are sought. The study presents a case study in the automotive domain, where FF technology was implemented to simulate mechanical button presses, reducing the JND FF levels that were between 0.04 N and 0.054 N to the JND levels of 0.254 and 0.298 when using a linear force feedback scale and those that were 0.028 N and 0.033 N to the JND levels of 0.074 and 0.164 when using a logarithmic force scale. The results demonstrate the technology’s efficacy and potential for widespread adoption in various industries, underscoring its significance in the evolution of haptic feedback systems.
