A mobile device is equipped with components to facilitate communication with another user, as well as controlling pointing on a computing device proximally disposed adjacent to the mobile device. The communication may be audio or textual. The mobile device includes a movement mechanism to generate movement signals, which are processed into pointing control signals and transmitted to the proximally disposed computing device. The movement mechanism may be an electro-mechanical mechanism, an optical-electro-mechanical mechanism, or an optical mechanism, integrated with the device, or disposed on an interchangeable cover removably mated with a core body of the mobile device. The pointing control signals may be transmitted as radio frequency signal employing a radio frequency signal transmitter, or infrared signal employing an infrared signal transmitter. Similarly, the transmitter may be disposed on an interchangeable cover removably mated with a core body of the mobile device.
