Working in game industry about 20 years. Worked for major game companies in Korea. I was interesting in HMD (Head mounted display) when it came out. At that time, it was not VR. But it was only interesting as HMD was not becoming that popular for people. When I knew oculus device, I started implementing and develop based on VR with my game development skill and know-how. And I keep challenge myself to get specific result from VR for general use. Suddenly now I am very first developer who implement game development technique and skill to medical training solution. Now I can present what I am researching and develop with VR and I believe it will change our future of training, life and more.
