Holographic optics for thin and lightweight virtual reality
If anyone here is in the know with the AR/VR scene, could they shed some light on why AR hasn't taken off yet?<p>VR is cool, but it's seems like such a more useful concept to me to have actual reality with enhanced information.<p>Imagine wearing glasses and looking at a plate of food then having it estimate + track calories and macros, or paint GPS direction arrows on surfaces realtime, or put people's names you've met before above their head so you can avoid awkwardly admitting you've forgotten it.<p>Is it technical limitations, or cost?<p>---<p>Edit: Many people replied with really informative answers to this already. I genuinely appreciate your time and insight, thank you :)
