ELECTRONIC BLACKBOARD, RECORDING MEDIUM, AND INFORMATION DISPLAY METHOD

Document Type and Number:

WIPO Patent Application WO/2017/057629

Kind Code:

A1

Abstract:

[Problem] To provide an electronic blackboard capable of appropriately determining an operation mode. [Solution] The present invention has: a coordinate detection means for detecting coordinates of an object in a display unit; a number detection means for detecting the number of objects on the display unit on the basis of the coordinates of the objects detected by the coordinate detection means; a time measurement means for starting the measurement of a prescribed time if the number detection means has detected a first object; and a mode determination means that, if the number detection means does not detect a second object even if the time measurement means measures the prescribed time, determines being in a first operation mode for displaying visible information on the basis of the coordinates, and if the number detection means has detected the second object before the number measurement means measures the prescribed time, determines being in a second operation mode for accepting an operation for the visible information.
