This week, I visited a startup whose office had a very unusual feature: a usability lab. There I was in a soundproofed room with a table in the center flanked by two chairs, one for a user and one product manager or UX researcher. On the table, a constellation of web cams record a user’s facial expressions and interactions with a mobile phone or laptop while a microphone captures the user’s voice.
