Scientists Unveil Screen That Produces Touchable 3D Images Using Light-Activated Pixels
Engineers at UC Santa Barbara have developed a revolutionary display that allows users to physically feel digital images in real time. The system uses optotactile pixels that expand when struck by light, forming raised bumps that match visual content. This wire-free design relies on heat-activated air pockets, opening new possibilities for interactive screens in smartphones, vehicles, virtual reality, and smart architectural surfaces where touch and vision seamlessly merge.
