The Augmented Reality Pad (AR PAD) (2001)

Prototyped in 2001, this device allow groups of individuals to view synthetic objects in real scenes, creating a collaborative "augmented reality". Unlike a head-mounted augmented reality display, the AR Pad is unencumbering, allowing users to see each others eye gaze and facial expressions. These non-verbal cues are commonly used in face-to-face collaboration. The ARPad was first demonstrated at the 2001 International Symposium on Augmented Reality (ISAR). It was developed by Dmitryi Mogilev, Mark Billinghurst, and Kiyoshi Kiyokawa (University of Washington HITLAB) and Jarrell Pair. The software was built using a modified version of the ARToolkit running on both Linux and Windows PC's. An updated version of the demonstration was shown at the 2002 SIGCHI conference.
