The question was deceptively simple. Could the light that is used to form an image on a display also be converted into something that can be felt? At the University of California - Santa Barbara, a team of researchers spent nearly a year exploring this idea, working through theoretical models, conducting simulations, and eventually building prototypes. Their work, described in the paper Tactile Displays Driven by Projected Light and explored in TechXplore, has led to a significant breakthroug
