I thought about the possibility of having notes in all my bedroom, in the walls, the ceiling… or even more, having a lot of small displays showing each one a different thing (an image or a video), I use to have random thoughts and I have projects where I need to have 2 or more screens displaying a different thing to increase my productivity, it would be nice to just put the glasses on and write things or put information anywhere I want to. Also, if you read about the loci study method, this could be taken to a new level with augmented reality. The problem is that I'm a complete newbie, where do I start? What glasses should I buy to do this? Do I need something more? In the case this information is useful: my phone has a ToF camera. Is there even a program or app able to do this? Thanks a lot and sorry for my bad english.
