Linux Journal: A GNU/Linux Wristwatch VideophoneJul 01, 2000, 19:35 (6 Talkback[s])

"This fully functioning prototype, designed and built by Steve Mann in 1998, was demonstrated in 1999 and later used to deliver a videoconference at ISSCC 2000."
"A VGA screen is configured using XF86 Config set to 640x480, 24-bit color, allowing video to be displayed at the captured resolution. The camera also operates at 640x480 resolution with 24-bit color video capture at 30 frames per second. Images may be processed or stored locally, or transmitted at a lesser rate. A future version will transmit images at the recording speed of 30 frames per second rather than the current six to eight frames per second limit imposed by the slow (2.4 megabits per second) radio link."
"One technical problem that arises from running GNU/Linux (GNUX) on a wristwatch is the input. We are experimenting with an input pie menu system. A user can easily select eight directions of the compass, but since this device has a clock face (at least, that is its concomitant cover usage), a 12-position pie menu makes the most sense."
