Holograms could quickly emerge as the next big thing in communications, allowing users to interact with spatially-designed virtual objects that enhance face-to-face interactions with emotion, realism, and depth. Using cutting-edge real-time 3D (RT3D) engines, a number of new businesses have started investigating immersive avatar development and photorealistic holograms for future communications platforms. Science fiction originally imagined these technologies, but they are already becoming (virtual) reality.
Currently, a variety of smartphone apps developed with Google's ARCore or Apple's ARKit may give the appearance of a 3D hologram. These produce a video of a hologram rather than 3D holograms. They blend digital objects with live video feeds. The app displays what the camera sees before overlaying digital images over the live video feed. Looking at the screen, the hologram seems to be a few feet in front of you.
