    摘要: A keyboard of a handheld electronic device is provided. The keyboard is divided into a number of key areas arranged in array. The keyboard includes character keys and function keys. Each of the character keys respectively occupies one of the key areas and has a first character symbol, while some of the character keys further have a second character symbol respectively. Some of the function keys have an activation key occupying one key area. The other function keys respectively include an ENTER key, a SPACE key, and a SHIFT key, each of which occupies approximately two key areas transversely. The arrangement of the keys enable users to press the key quickly, correctly, and conveniently.

    摘要: A handheld electronic device and a method for switching a user interface thereof are provided. The present method is suitable for a handheld electronic device having a first part and a second part. The first part comprises a screen, and the second part is slidingly disposed below the first part along a specific path. A part type of the second part is detected when the second part is slid out along the specific path relative to the first part. Then, the user interface is switched and displayed on the screen according to the part type, wherein the displayed user interface is corresponding to application programs relative to the part type. As a result, convenience of executing application programs on the handheld electronic device can be improved.
