Holographic-like video conferencing: a killer app for AR?
This year, Mobile World Congress was all about 5G, infrastructure and handsets, getting ready to support data-intensive low-latency VR content wirelessly.

This means the AR glasses can become an affordable and lightweight smartphone accessory rather than an expensive standalone product with limited battery time, compute power or memory. With front-facing cameras integrated behind the glasses to feed SLAM (Simultaneous Localization and Mapping) algorithms together with a 6DoF tracking inertial measurement unit, the glasses are capable of plane detection and object recognition. With a slick touch and pressure sensitive controller that nreal provides with its glasses, users could decide to stick video content to a wall so it runs there, with the correct perspective regardless of where they stand in the room (a video-enhanced empty wall if you like). With the nreal light glasses eeNews Europe was able to put on, 3D animated characters were not only floating in front of our eyes, they were truly integrated as volumetric content blending with reality, with their own coordinates within the real surroundings. One could walk to the avatars or in full circle around them, always rendered with the appropriate perspective as if they were true holographic projections.

Bea expects such glasses to be used for casual gaming and entertainment (without being locked to a screen), but also for productivity and video conferencing. One could easily imagine the emergence of slim retrofit multi-camera arrays (like a smart door frame) to create dedicated holographic conferencing spots in the home, allowing AR glass wearers to share their own real-time 3D holographic impression with their AR interlocutor as they talk.
