World's first interactive 3D holographic display | A team of Spanish engineers has created the world's first 3D hologram that can be physically interacted with.
Remember the scene in Iron Man 2 where Tony Stark rediscovers a new element and is handling virtual 3D holographic elements with his hands, moving them around, pinching, swiping, flicking, and tossing? Pretty cool in 2010. What about 2025?
Holograms are generally made using swept volumetric displays, meaning images are projected at different heights nearly three thousand times per second onto a rigid oscillating surface called a diffuser, giving the appearance of a three-dimensional object without the need for special glasses or headsets. Using gestures you're already accustomed to with your phone's touch screen – swipe, touch-to-select, pinch, rotate and more – a user can effectively control and manipulate these holographic objects through the elastic diffuser. Dr. Bouzbib has said she's looking to further improve the design using focused ultrasound or conductive threads to simulate haptic feedback ... leaving me wondering if the flappy elastic isn't shocking enough.
