“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 640×480,
24-bit color, allowing video to be displayed at the captured
resolution. The camera also operates at 640×480 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.”
