Abstract
A feedback-enhancing film includes: an elastic layer comprising a first polymer exhibiting optical transparency and elasticity; and an interface layer arranged across an upper surface of the elastic layer comprising a second polymer exhibiting optical transparency, impact resistance, UV resistance, and smoothness to touch. Additionally, the interface layer and the elastic layer mutually deform to resist transverse movement of a stylus tip across the interface layer in response to an application of writing force to the interface layer via the stylus tip. The film can also comprise a system including: the film; a stylus including a stylus tip; and a touch-sensitive screen.
