Data or electrooptic sensor images are made of a star field and at least one, and possibly multiple, Earth satellites associated therewith. A matrix is used to relate button depression and navigation screen to a particular activity. The mobile terminal receives a visualization request from the process; selects data in accordance with the visualization request; and displays the selected data the display area. Air pressure is delivered to annular pistons to cause the inner housing to extend and retract. A subtracter subtracts this noise component from the luminance signal supplied from a delay circuit, thereby outputting a luminance signal reduced of noise through an output terminal. When the biometric characteristics are analyzed at the second telecommunication device, a display is generated depicting the mood, gender, age, urgency or other characteristics of the caller associated with the incoming call.
