This is about the first time I’ve ever experienced immersive feeling in my life. I was in elementary school then and I went to Hong Kong Disneyland with my classmates. I can still remember an attraction called Mickey’s PhilharMagic. It is a “4-D film attraction” which was basically a 3-D movie with exaggerated movements: things may “move” very “close” to the audience very fast and makes the audience to dodge backward. There are other techniques involved, mostly making physical phenomenon like wind or fire. That’s probably not the first time I’ve ever watched a 3D movie but I was really impressed by that. That was the first time I’ve ever felt myself interacting with the characters in the movie and I felt myself inside the movie. I really appreciated a couple of details. Once there were many gems and jewelries pop out of the screen and came close to my face. I reached out my hand trying to pick up the gems and then realized how stupid I was because they were not there. The other time was a mop running over the stage and splashed water to audience’s faces. There was actually water coming out and poured onto my face. But if you will never expect that there are some water shooting devices assembled in the “fences” in front of the first row. Because people cannot see where the water came from, it became more real as if the mop splashed water onto the audience’s faces. Besides, when there was fire on the screen, the temperature in front of my face will rise and my face was like burning. When the characters were flying, there was wind blowing on my face. Of course, all those heating devices and fans were hidden. The seats could create acceleration as if I was flying or dropping from a cliff, too. It did not have to move very long distance or drop from very high position, the acceleration was the key that makes the movements very real. It was really amazing.
