摘要

Touch, though governed by universal physical principles, is experienced idiosyncratically. The first foundation established how skin mechanics and psychophysics define the pathways by which tactile information is gathered, transmitted, and encoded—forming the baseline operating envelope for haptic systems. The present chapter extends that foundation by addressing the variability of human touch: how anatomical, biomechanical, and cognitive differences shape what individuals feel, and why this variability must be explicitly accounted for in the design of integrated haptic systems.
