摘要： In the coordinate-position inputting/detecting device, the light receiving/emitting devices emit light beams spreading in a fan shape and travelling along an entry area. The light receiving/emitting devices also receive the light beam reflected by a recursive reflecting member and detect the distribution of the intensity of the received light beam. 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.

摘要： 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.

摘要： 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 of the apparatus includes a coordinate determining device to determine two-dimensional coordinates of the designating device in the coordinate inputting/detecting area. A distance determining device determines a distance of the designating device from a surface of the coordinate inputting/detecting area when the designating device is located on or in vicinity to the coordinate inputting/detecting area. A storing device stores information of the two-dimensional coordinates determined by the coordinates determining device and information of the distance determined by the distance determining device so as to be associated with each other. A coordinates change detecting/storing device detects a change of the two-dimensional coordinates information at a predetermined time interval and stores the detected change of the two-dimensional coordinates information. A distance change detecting/storing device detects a change of the distance information at a predetermined time interval and stores the detected 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 information and the distance change information.
