I saw a total of about 10% of things around me in the airport of Los Angeles, CA, last Sunday on the way from Taiwan to Houston, Texas. The picture I get was not complete. They were like pictures printed on a cloth with holes everywhere. Most of the things I could see were the things right at my eye levels. It looked like 90% of the environment didn't have pictures, I didn't feel dizzy or anything. I just could not be sure what was really around me. If a car ran toward me, I won't be able to run away from it because I couldn't tell if there were obstacles around me. I didn't have control over what I wanted to see.
