A user interface with guide lights for a communications device, such as a mobile telephone, is provided to assist a user in the correct and efficient operation of the device having a display, and a keypad which contains a numerical 10-key and other control keys. The user interface includes a means for identifying the appropriate keys on the keypad which correspond to the step or steps required to activate a desired operation to be performed within the device. In the preferred embodiment, identification of the appropriate keys is achieved using a light source which is mounted beneath each translucent key so that when the light source is illuminated, the key associated with that light source will be identified to the user. The intensity of the light sources is variable and may be controlled to provide sufficient contrast to read all keys in low ambient light while highlighting the keys to be pressed for operation of the desired function. In high ambient light, the intensity of the guide lights may be increased for enhanced contrast and visibility. Alternatively, different color light sources may be used, with one color to light all keys for visibility in low ambient light, if needed, and the other color to provide the guide lights.read more
