Hi, I am Frank, a hardware engineer from Taiwan. If you are a maker like me and sometimes build things  your own. We provide both software and hardware kids for you to make VR game systems like golf simulators, shooting simulators.
WIth our golf simulator kits like ONEPPTECH's golf simulator software, the price is only US$149 per year, you can buy a OAK-D from OpenCV for $199. Then you have the key hardware and software of a golf simulators.
And we are developing more VR application using  OAK-D, so the OAK-D will be uses in other simulator.  So you can use OAK-D in multiple applications with less money and have more fun!
Due to ONEPPTECH's software copy right, we can not sell ONEPPTECH's software with DTG-201. For customers interested  can contact ONEPPTECH  directly.
DTG-201 is a 200 fps VR camera and we use it to catch golf balls speed and direction. Can be used in CG3D's golf softwares. For ONEPPTECH's golf software we support OAK-D only.
All product supports are forum based at http://vrmaker.tw, please be patient if we could reply your question immediately!  
Make and have fun!
