Abstract: A schedule management system which can display a schedule on a screen and enables the user to enter schedule topics promptly and accurately without performing complicated operation is provided. An external voice is input through a microphone or a network control unit and is converted into a digital signal by an A/D converter and a coder. An identifier related to the digital signal is generated. The identifier is displayed on a schedule on a display unit. The digital signal is stored in a memory in relation to the identifier. A user specifies the displayed identifier through an operation section, whereby the digital signal related to the identifier is extracted from the memory by a CPU, the extracted digital signal is converted into an analog signal by a D/A converter, and the analog signal is output as a voice through a loudspeaker or the network control unit to the outside. Like a voice, an image can also be handled.

Abstract: An integrated information processing apparatus is provided with a display device and a generally transparent input tablet having an input surface placed on a display surface of the display device for outputting a pointing coordinate which is a coordinate on the input surface pointed by a user's finger or an indicator. The apparatus includes a circuit for determining an indication direction extended point coordinate from the pointing coordinate output by the input tablet and a predetermined value, and a display processing section for displaying a point on the display surface of the display device corresponding to the determined indication direction extended point coordinate so that it is distinguishably displayed on the display device.

Abstract: An input panel interface section is responsive to an input signal from an input panel to provide input coordinate data indicating an input position in a coordinate system used in the input panel. A converter converts the input coordinate data provided by the input panel interface section into display coordinate data. The display coordinate data is data in a coordinate system used for a display controller to determine a display position on a display. The display controller controls display output to the display by using the display coordinate data output by the coordinate converter. A CPU interface section controls access of a processor to the display controller, the input panel interface section, and the coordinate converter.
