摘要: A numeric keypad configuration facilitates accurate keypresses by varying key heights to provide obvious tactile feedback to a user. A home key (160) in a keypad (100) has a lower height (265) than the other keys in the matrix. After locating the home key using touch, surrounding keys can be quickly and accurately located also without looking at the keypad. Additionally, instead of printing a number or letter on the surface of a small key, alphanumeric labels (120) are provided in the spacing area between the keys on the telephone front housing (180) and illuminated, thus improving visibility of the numbers and letters in dim lighting situations. This numeric keypad configuration can be used on cellular telephone keypads or any electronic device where a small numeric keypad is desirable.

摘要: A keypad configuration for an electronic device has a housing (180) with one or more push buttons (110) having centers (113), a maximum radius (115), and a maximum height (215). A specific area (118) surrounds each push button and has a minimum radius (129) that is at least five times as long as the maximum radius of the push button or at least three times as long as the maximum height of the push button. No additional push buttons are within this specific area. The size, height, and spacing of the push buttons provide a point contact sensation to a user's fingertip, which prevents a user from pressing more than one key at a time and provides space for alphanumeric labels beside each push button. This keypad configuration is particularly suited for portable electronic devices where a small keypad is desirable, such as cellular telephones.
摘要翻译: 用于电子设备的键盘配置具有带有一个或多个具有中心(113),最大半径(115)和最大高度(215)的一个或多个按钮(110)的壳体(180)。 特定区域(118)围绕每个按钮并且具有至少是按钮的最大半径的五倍的最小半径(129)或至少是按钮的最大高度的三倍。 此特定区域内没有其他按钮。 按钮的尺寸,高度和间距为用户的指尖提供点接触感,防止用户一次按下多个键,并为每个按钮旁边的字母数字标签提供空间。 该键盘配置特别适用于需要小键盘的便携式电子设备,例如蜂窝电话。
