Abstract: A system for delivering contents includes a center system which delivers the contents, a plurality of terminal systems which receive the contents from the center system and displays the contents, and communication lines connecting the center system to the plurality of terminal systems. The center system includes a delivery-schedule setting unit which sets a schedule of delivery, and a contents-delivery unit which delivers the contents to the terminal systems according to the schedule of delivery during a time period when a load on the terminal systems is lower than a predetermined level.

Abstract: An optimal pen color is automatically selected for a given background color based upon a predetermined relative distance in the Munsell color-order system. The predetermined distance is defined in terms of saturation, hue and or lightness. In general, sufficient visual distinction is observed when the color representations of the pen and the background are separated by the predetermined relative distance in the Munsell color-order system.

Abstract: An electronic blackboard displays information and optically detects input information on a display/writing surface by determining the corresponding coordinates. To determine the input coordinates, a predetermined number of pairs of light emitting elements and light detecting elements are placed in parallel for each axis near the edges. The light emitting elements and the light detecting elements are also linearly and equidistantly placed. A control unit is connected to the light emitting elements for sequentially activating these light emitting elements and for controlling the light detecting elements to detect the light in an overlapping manner. Based upon the above positional information from the light detecting elements, an input coordinate determination unit determines the input coordinates of an input on the display/writing surface.

Abstract: An electronic blackboard displays information and optically detects input information on a display/writing surface by determining the corresponding coordinates. To determine the input coordinates, a predetermined number of pairs of light emitting elements and light detecting elements are placed in parallel for each axis near the edges. The light emitting elements and the light detecting elements are also linearly and equidistantly placed. A control unit is connected to the light emitting elements for sequentially activating these light emitting elements and for controlling the light detecting elements to detect the light in an overlapping manner. Based upon the above positional information from the light detecting elements, an input coordinate determination unit determines the input coordinates of an input on the display/writing surface.

Abstract: A coordinate inputting/detecting apparatus, for optically detecting a position of a designating device inserted into a flat or substantially flat two-dimensional coordinate inputting/detecting area, and including a coordinate determining device to determine two-dimensional coordinates of the designating device in the area. A distance determining device determines a distance of the designating device from a surface of the area when the designating device is located on or in vicinity to the area. A storing device stores information of the determined coordinates and information of the determined distance. A coordinates change detecting/storing device detects and stores a change of the coordinates information. A distance change detecting/storing device detects and stores a change of the distance information. A state allocating device allocates at least one designating state among designating states of the designating device stored in advance, based upon the coordinate change and distance change information.
