For starters, the SeeThru headset doesn't come equipped with a camera. That means no video recording or pictures, and for some headsets out there, it could mean a real decrease in AR data, too. Thankfully, the SeeThru headset makes up for its lack of visual data with a whole suite of built-in sensors. Three separate gyroscopes, accelerometers and compasses make sure that your headset knows exactly where you're looking at any given time.
