Photos go beyond the inkjet

Article Abstract:

Three photo printers from camera companies offer improvements over inkjet-printed photos from digital cameras. The entry-level Polaroid P-500 uses the memory card from the camera to print to Polaroid instant camera film. The paperback-sized unit is portable, but the image quality is not as good as photo lab results. The Sony DPP-SV55 uses the dye-sublimation process to produce commercial quality 4x6 prints. It can attach to a Mac or Windows machine, or operate from camera memory cards. The Olympus P400 can print 7.6 by 10 inch photos at a 90 second per image rate. The fact that you don't pay for images you don't want makes even the most expensive of these systems competitive with processing services on a cost per image basis.

Lifting the cover of those ubiquitous touch screens

Article Abstract:

Computer touch-screen systems, using either a finger or stylus, are the easiest computer systems to use. Touch screens employ two technologies to make them work: one that displays the items on the screen and one that computes what the finger or stylus has chosen. The systems must work quickly. The resistive overlay system was the first touch-screen technology developed. It is still used, along with the newer surface acoustic wave technology and infrared screens.
