Hello, I'm Daniel Yelamos and I'm the CM of ARLab, a Spanish-Israel company that develops AR solutions. We've released a couple of SDKs and a few apps based on AR to help people develop this kind of software.
If you are interested in AR development you can check out our products or our open betas. Furthermore you can see what we're up to in our blog, our facebook or our twitters: @arlabdev and @arlaboratory.
I hope to see you in linkAR!
