INPUT SYSTEM BASED ON SPATIAL MOVEMENT, ENABLING USER TO DIRECTLY PERFORM INPUT TO IMAGE EXPRESSED IN DISPLAY DEVICE THROUGH MOVEMENTS ON SPACE WITHOUT MANUAL OPERATION OF THE USER

摘要

PURPOSE: An input system based on a spatial movement is provided to enable a user to directly perform input to an image expressed in a display device through movements on a space without a manual operation of a user, thereby stimulating a user's curiosity on the displayed image while inducing the user's participation. CONSTITUTION: A spatial input device(200) includes a frame having an input space which is empty inside, and two cameras installed on the frame with angles of incidence toward the input space. An image device(300) projects an image on a space or a side far away at certain intervals from the spatial input device(200). A control device(400) controls operations of the spatial input device(200) and the image device(300), converts position information into 2-dimensional coordinate values to display the image, and executes an activation command of an activation menu when a pointer indicated on the image is recognized as the active command.
