dusting (e.g. multiple exposure) pictures of wristwatch computer videophone

wristwatch computer videophone in white light:

lighting variations (keeping front dark so screen can be seen):

closeup view of screen

toplit only variations (only lightvectors from above):

single exposure pictures of wristwatch computer videophone in use (with camera signal in freeze-frame mode for approx. 1/4 sec. to 1 sec. exposure in the f/5.6 to f/11 aperture range)

some of these pictures are blurry on screen (e.g. trying to hold my hand still in a completely dark room for 1/4 sec to 1 sec or so, so that the screen would show up in the picture, illuminated only by a flashlamp, variously in the 25 to 800 joule output range, 480 volts, fired at 6 kV trigger, during the exposure).

also, because the video was freeze-framed for the long exposure, the clock hands sometimes painted it over (had to keep refreshing the window behind the clock), so some pictures have partially obliterated screen behind the clock.

however, three of these pictures: frame numbers 464, 466, and 472, appear to be satisfactory:

463 464 465 466 467 468 469 471 472

ISSCC: 'Dick Tracy' watch watchers disagree

By Peter Clarke

   SAN FRANCISCO -- Panelists at a Monday evening (Feb. 7) panel session
   at the International Solid State Circuits Conference (ISSCC) here
   failed to agree on when the public will be able to buy a "Dick Tracy"
   style watch for Christmas, with estimates ranging from almost
   immediately to not within the next decade.
   Steve Mann, a professor at the University of Toronto, was hailed as
   the father of the wearable computer and the ISSCC's first virtual
   panelist, by moderator Woodward Yang of Harvard University (Cambridge


   Not surprisingly, Mann was generally upbeat at least about the
   technical possibilities of distributed body-worn computing, showing
   that he had already developed a combination wristwatch and imaging
   device that can send and receive video over short distances.

   Meanwhile, in the debate from the floor that followed the panel
   discussion, ideas were thrown up, such as shoes as a mobile phone --
   powered by the mechanical energy of walking, and using the Dick Tracy
   watch as the user interface -- and a more distributed model where
   spectacles are used to provide the visual interface; an ear piece to
   provide audio; and even clothing to provide a key-pad or display.
