The new “attentive and more considerate” office cubicle helps increase work focus for those who share space with many others. It automatically “mediates audiovisual communications” between co-workers by using information gained about their “social orientation” in an office, says Dr. Vertegaal.[...]
The attentive cubicle’s walls are constructed of a translucent material called Privacy Glass™ that consists of a glass pane with an embedded layer of liquid crystals. Overhead cameras mounted in the ceiling track the “social geometry” between co-workers. When potential communication partners are detected, the cubicle’s walls automatically change from opaque to transparent, allowing for visual interaction.
A little creepy--"HAL, please let me talk to Bob." "Dave, I'm afraid I can't do that."--but interesting.
