AR is a buzzword we hear everywhere. But is it really possible to build enhanced AR experiences quickly? There were quite a few attempts to bring AR to Android, but they were not easy to implement or required special hardware. ARCore solves both of the problems. It is a fast and performant SDK providing great API to build AR focused apps using just a phone’s camera. The slides cover AR main concepts, geometry detection, object rendering and potential problems. Lessons learnt are also shared from the experience of building e-commerce AR experience at Jet.com.
