What the camera was picking up was the quick and accurate positional tracking. That alone almost makes it feel like it is 3d. However, when you're looking through the glasses you also get stereo vision which gives true depth perception as well.
It was really cool and I could see this as being an engineering tool. Visualizing an object as a solid and being able to manipulate it could be quite helpful.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
