<p>A method and apparatus for navigating an image viewed on a display screen (320). The image is controlled by a processor (215) that receives navigational commands selected on a touchscreen (205) of an auxiliary display device (200). The touchscreen (205) is partitioned into a plurality of navigational control areas (210, 220, 230, 240, 250, 260, 270, 280). Each navigational control area is associated with a different navigational command. When one of the navigational control areas of the touchscreen (205) is selected, the navigational command associated with the selected navigational control area is transmitted to the processor (215). The processor (215) receives and executes the transmitted navigational command to navigate the image. The boundaries of the control areas are normally hidden from view, but can be revealed on the touchscreen (205) in response to a user input.</p> |
