Abstract

A compound portable computing device (100) comprising two or more separate portable devices (101, 105) coupled over a wireless link. A first portable computing device (104) contains a first portion of a full-size QWERTY
keyboard. A second portable computing device (105) contains a second portion of the full-size keyboard. The first portion and the second portion together comprise the keys of the full-size keyboard. A network link couples the first portable device (104) to the second portable device (105). A partial keyboard map is loaded into memory of the first and second devices. The partial keyboard map in the first device (104) corresponds to the portion of the keyboard contained in the first device (104), and the partial keyboard map in the second device (105) corresponds to the portion of the keyboard contained in the second device (105). The partial keyboard maps allow the first and second portable devices to operate as a full-size keyboard.
