COMMUNICATION DEVICE INCLUDING ONE OR MORE ELECTRICAL CONTROL BUTTONS IN AN UPPER HOUSING PART

摘要

Folding wireless communication devices (100, 700) comprise first parts (102, 1002) that are rotatably coupled to second parts (104, 1104). The first parts (102, 1002) can be moved from first positions in which the first parts (102, 1002) overlie the second parts (104, 1104) to second positions in which the first parts (102, 1002) extend upward away from the second parts (104, 1104). The first parts (102, 1002) comprise one or more buttons (302, 304, 306, 308 1010, 1012), e.g., a pair of directional buttons, such as "UP" and "DOWN" control buttons (302, 304, 1010, 1012). Hardware and/or software is used to change the function of the buttons (302, 304, 306, 308 1010, 1012) depending on the position of the first parts (102, 1002).
