Start-up Avegant is making some waves with a Virtual Retinal Display. VRDs have been invented back in the 80s, but never made it to the market. Avegant is maybe finally the one that brings us VRD glasses.
Head mounted displays are back in the trending technology since the Ocolus Rift glasses got traction on Kickstarter. HMDs have been a major tech trend also in the early 90s. If we are now closer to making HMDs a success remains to be seen. THe current LCD based HMDs are in my mind not the future.
The idea of projecting light onto our eyes is the way to go as it is the natural way of seeing. The technology was invented back in the 80s in Japan. There have been several attempts since to make VRDs a product. CNET featured now the VRD prototype of a start-up called Avegant.
The good news it works and the resolution is already at twice that Oculus Rift is providing. The setup is though still very rough. It will still take a while until these glasses hit the market, but they are clearly the future of HMDs.
