Sliding Doors
Public bathroom doorway, Karuizawa, Japan, January 2008
Before we hiked up the nearby mountain I wanted to use the bathroom. I was very frustrated to find the door locked. I pushed and pulled and saw the keyhole for the deadbolt and figured I was out of luck. Then I saw someone enter the adjacent women’s room – by sliding the door. I wouldn’t expect a bathroom door to slide, and I didn’t interpret any of the cues (or affordances) about how this door works to suggest sliding was a possibility.
