Simulating Softness for Haptic Interfaces
- Magazine Article
Researchers have developed a formula that enables them to recreate different levels of perceived softness. Based on the results from their experiments, they created equations that can calculate how soft or hard a material will feel based on material thickness, Young’s modulus (a measure of a material’s stiffness), and micropatterned areas. The equations can also do the reverse and calculate, for example, how thick or micropatterned a material needs to be to feel a certain level of softness.
