First Claim
1. A wristwatch having an input/output device, said wristwatch comprising:
- a display, said display displaying a selected set of input characters;
a wrist band connected to said display for securing said display to the wrist of a user;
a flexible assembly operatively connected to said display;
said flexible assembly having a set of character keys located thereon, each of said character keys associated with an individual character of said selected set of input characters and at least one control key, wherein said selected set of input characters comprises a single row of characters from a set of keyboard rows, andwherein actuation of any of said characters keys causes the character associated with said actuated key to be input into said device and actuation of said control key causes said currently selected set of input characters to be changed to a different set of input characters, andwherein said flexible assembly is pivotal from a position where said assembly extends substantially along and underneath said wristband to a position substantially perpendicular to said wristband.

Abstract
A keyboard type input device used in conjunction with a wristwatch or a portable telephone has multiple key positions provided as character entry keys. Each key corresponds to one key in the selected row of the conventional QWERTY keyboard. A second set of control buttons provide for the selection of which row of a conventional QWERTY keyboard are represented by the character keys in addition to other functions such as case shift, and alpha-numerical control functions. A selected row is shown on a display, as visual feedback. Alternatively the keys are implemented as LCDs with pressure sensors and the characters of the selected row are displayed directly on the corresponding key positions. The keyboard finds particular use in portable devices as it demands less space than traditional keyboards.
