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.

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.

At least two image pickup devices are provided with a prespecified space therebetween on a peripheral section of the entry area for picking up images of the pointing body illuminated by the light from the lighting device. Position on the CCD of the image pickup devices where an image of the pointing body is formed is obtained according to output from each of the image pickup devices. Coordinates of the position of the pointing body in the entry area are calculated from these positions.

The coordinates of a position of a pointing body such as a user's fingertip or a pen inserted in the entry area is identified using the distribution of intensity detected by the light receiving/emitting devices.

Abstract: An apparatus that includes angle detection sections periodically detecting a point on a panel as angles. An angle storing section stores the angles detected during an immediately earlier Ucycle among angles periodically detected, and an angle choosing section chooses angles which are most adjacent to the angles stored among angles detected during the immediately earlier cycle when a number of angles detected during a present cycle is greater than a number of angles detected during the immediately earlier cycle. A coordinate arithmetic section detects during the immediately earlier cycle coordinates based on the angles chosen. In this apparatus, when the number of angles detected during the present cycle is one greater than the number of angles detected during the immediately earlier cycle for each angle detecting section, the coordinates inputted by an other pointing device can be detected through angles which have not been chosen.

Abstract: An information sharing area, employed by all conferees for sharing information (object) or personal knowledge transmitted via information processors from conferees, and an editing display area, employed for editing a structure of the information (object) or shared knowledge, can be definitely distinguished from each other and displayed in a large display device commonly visible from all, conferees. When the areas are displayed in the large display device and one of the objects displayed in the information sharing area is designated, the designated object is displayed at a desired location in the editing display area and can be edited through cooperative works by all conferees centering around a conference chairman.
