A glass or acrylic panel with 4 wires connecting to the mouse port of a computer. Touching the screen passes electric charge through the wires and the position of the stylus on the screen can then be determined by the software. The 4-wire is less expensive and slightly less hard-wearing than the 5-wire type and is more often used in the home, school, or office. A PDA would probably incorporate 4-wire technology, while an in-store kiosk would incorporate 5-wire technology.
