Achieving razor-sharp vision in the metaverse

Thanks to the enhanced light-field technology developed by EPFL spin-off Creal, augmented-reality and virtual-reality images appear increasingly life-like with less strain on users' eyes. The company will present the latest version of its system at the Augmented World Expo this week in California. Augmented reality and virtual reality could one day be part of our everyday lives, whether we're buying groceries, attending a meeting, playing a video game or even undergoing surgery. Some tech enthusiasts believe that many of our day-to-day interactions could soon take place in the metaverse - an alternate world where people move seamlessly between the virtual and physical realms. But before that can happen, many improvements need to be made to AR and VR systems, such as to improve touch and smell capabilities, streamline the interfaces with virtual elements, and display more life-like images. It's this last challenge that Creal's founders decided to address with their new generation of light-field technology. Creal's system enables the human eye to focus on virtual objects at any depth, just like with objects in the real world.
