Sensors Walk...

I added the class late and now i'm finally on the blog, here is my sensors walk post. I saw two types of button-sensors; one was a handicap access door-opening button near the north entrance to FAC, the other button was a blue emergency or panic button near Plaza of the America. I also saw a reverse camera on a large cargo truck near Little Express. Another "sensor" I noticed was a large LCD TV screen on the 1st floor of FAC. What I though was interesting about the TV was that it kind of worked as a "reverse sensor" that attracts passer-by's attention; humans sense the TV. I feel that we easily walk by most signs and advertisements, but the moving images on the TV are extra attractive to our eyes.
