ABSTRACT:
A communications device, such as a cellphone, functions as a peripheral for a processor, such as a laptop computer. The cellphone and the laptop are directly coupled via a communications link that is not the cellular network. Audio, still images, video data, and/or user interaction options are provided to the cellphone by the laptop via the communications link. The audio data is rendered by the cellphone via the cellphone's speakers or by a headset. The still image or video data is rendered by a display on the cellphone. User interaction prompts are rendered by a display, audio, or tactile feedback on the cellphone. The user input/responses are made through the keypad or other input method (e.g. wheel) and are provided back to the processor. The communications link is a Bluetooth compatible link. Utilizing the cellphone to render video data preserves the life of the batteries in the laptop.
