Not exactly the same thing but I've actually been sitting on an idea for a mobile app that was inspired by Google: Essentially, you'd be able to look through your phone camera and draw on the world on the screen. Then other people could see your geolocated creations and maybe modify them. (I also considered autodecay for dense areas) I never did figure out the physics of how the projection would work or if the accuracy of GPS made it feasible, but I thought it'd be a good way to blend our real world and allow a sort of "virtual graffiti", a form of augmented virtual reality. As with all interesting ideas though, if you wait too long, someone comes and does it and I saw something similar on HN except with stickers also. As for how Google inspired it, their photo app lets you physically rotate your phone to pan around photospheres.

TiltBrush seems more of a pure creative endeavor meant for artists or anyone just looking to mess around a virtual world. I really much like how you can walk around the creation/space. The fact that it's three dimensional actually makes it more like sculpture than painting, though I"m sure there isn't anything other than parallax errors preventing 2D drawing. The granularity of the brushes seems to be good, so it will all come down to how well the hand controllers will work together with the headset. (hopefully not requiring surgery-like stillness just to get small details right, maybe by allowing adjustable head movement sensitivity)

String did "virtual graffiti" in 3d in 2011! https://vimeo.com/15935674

When I last explored this idea, "stickers" are necessary since most surfaces in real life are generic "textures", so there's no way to know which section of a wall you're looking at if you're too close to it.

Interesting how it's in 3D, and pretty interesting considering how early it was done. (back before all the Oculus hype) Oh and sorry what I meant by stickers were colorful cartoon drawings popular in Facebook and LINE. Although what you're saying does make sense in regards to manipulating surfaces.

I saw a beta of this at a recent Berlin meetup that sounds similar to what you're talking about: http://gibbl.xyz/

That's pretty sweet, especially the tracking. Building blocks might be slower but the results look much better and friendlier haha. Kinda like Minecraft for the real world :).

Is it similar to what hololens is trying to achieve here: [1]

Thanks for the link! I think their approach of including the real-world is very exciting and has just as much potential as completely virtual applications.

Edit: Just realized you were asking me a question. Well nothing quite as advanced. The user would look through their camera on the phone screen and draw directly on the screen and also be able to see other people's overlays, kinda like snapchat but in 3D and realtime. If I find the implementation I saw on HN I l link it.

check out http://www.glif-it.com This sounds similair to what you described, in beta stage now.

I like how it takes the idea even further into a sort of social bulletin board. (also like snapchat for the real world) Making it text-only is also an interesting choice which makes it seem aimed towards notes.
