Last August, the Virtual Reality Developers Conference (VRDC) published its first report on the status of the VR industry based on a survey of developers. The results show that HTC Vive has a slightly larger number of developers than Oculus Rift. Recently, the second report has been published and the gap between the two has slightly increased. The second VR/AR innovation report came from more than 600 developers working on VR, AR, and MR. Last year, the number was more than 500. Of this year's developers, 56% said they are developing for Vive, and 49% of respondents said they are working for Rift. The gap between the two is 7%, which is a little larger than the gap of 5.4% last year. Sony's PlayStation VR (PSVR) also increased, from 12.9% to 19%. Other platforms such as Google Daydream and Microsoft HoloLens are also in the statistics, and the developer ratio of GearVR has dropped from 33.8% to 33%, which is surprising.
