Samsung's AR Emoji may be useful for considerably more than the occasional funny reaction GIF. The tech giant recently received a US patent for a "hybrid visual communication" system that would replace live video of a person with an augmented reality 3D model (basically, AR Emoji) that reflects their facial expressions in real time. This virtual self would stand-in for you during video chats when your connection is flaky, so you could hold a call without the stops and stutters that come with low bandwidth. We'd add that it could be helpful for those moments when you're less-than-presentable but still want to talk face to face. Just got out of bed? You won't look quite so groggy.
