In August last year, the Virtual Reality Developers Conference (VRDC) released its first report on the VR industry based on a survey of developers. The results show that there are more developers using HTC Vive than Oculus Rift. Now that the second report has been published, the gap between the two has further increased. The second report investigated more than 600 VR/AR/MR developers, more than 500 respondents last year. 56% of developers stated that they are developing Vive content, 49% of developers stated that they are developing Rift content. The gap between the two is 7 points, which is higher than last year's 5.4 points. The popularity of these two headphones is also Calculate high. The proportion of Sony PSVR content developers jumped from 12.9% last year to 19% this year. Platforms like Google Daydream and Microsoft HoloLens are also starting to take off. However, the developer of the Samsung Gear VR dropped from 33.8% to 33%, which is surprising. The report also investigated the developer’s upcoming platform for the next app. Vive again won 52% of the time, and the Rift was also very close, with 50%. Gear VR, Daydream, Cardboard and PSVR are behind it. On the other hand, Vive is also the most popular platform for exclusive publishing choices, with 35% of content planned for exclusive distribution on HTC's platform. Although Oculus provided funding for exclusive content, it was only 13%. Of course, there are also some developers who first published the project on Vive and then moved to the Rift and PSVR platforms. In other respects, the survey also found that most of the projects were funded by internal developers and individual funds, and only 5% of projects were funded by external publishers. Most people think that the VR technology can make a profit in the middle period of development. 16% think that they can make profits in the short term, and 8% think that VR technology can't benefit. Overall, this year's report seems to be roughly the same as in previous years, and there are no signs of rapid growth. After all, VR/AR is still in its infancy and it may take a long time to see obvious changes in the investigation report.
