<p>The invention is a hand-held device (Fig. 1). It comprises multiple keys (112, 113) on its face ('face-keys') and one or more buttons (101, 102, 103) on its side ('side-buttons'). A user types a character (or invokes a function) by pressing one of the face-keys using a finger on the hand that is not holding the device while simultaneously holding in combinations of the side-buttons with fingers on the hand that is holding the device. Pressing a face-key without holding in any of the side-keys produces a given character (or function). Pressing the same face-key while simultaneously holding in a given combination of the side-keys can result in a different character (or function). The invention allows for faster typing of text on cell phone handsets and other hand-held devices.</p> |
