When I experienced with the simulator tool, my observations are except the totally blind one, I could still read some words from the other three kinds of vision loss, even though not very smoothly.
(Totally Blind)Then I wear a sunglasses with a lot of glue on its glass and I began to walk around. I tried to walk up the library stairs and though I could feel the steps by foot but when I took a look at the stairs, it was just a whole white stripe without any gradient. When I experienced with the elevator, it was hard for me to push the floor button and I ended up push all buttons and the elevator stopped every floor. The stairs in CUB was easier to use compared to the stair in library since there are color contrasts to inform me where steps start and end. Then I went to the Bank of America ATM machine, the location for the card swipe and the key-pad were found easily since there are red lights near the card swipe and I could touch and feel where the key-pad located. Mostly, because I used this machine a lot, so the familiarity helped. There is one more thing I want to mention is natural light was always very noticeable, it appears light blue and I could easily tell it. Generally speaking, everything seems blended together when I wear that glass and I begin to have a general sense of how people with low vision live, work and behavior. I will incorporate those observations in my future design to help people with low visions live better and more comfortable.
