DATA PRESENTATION DEVICE AND ITS OPERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique by which an image to be presented is easily selected by using a thumbnail image and simultaneously such selecting operation is done without being viewed by a viewer in presentation using a data presentation device. SOLUTION: The thumbnail image group 123 of a plurality of data images is displayed on the touch panel type input device and display device 122 of a portable information processing terminal 121. An explainer 120 selects a required image from the thumbnail image group 123, and pushes it by a touch pen 118. A signal to specify image data corresponding to the thumbnail image designated by the touch pen is transmitted to the data presentation device 101 from the portable information processing terminal 121. The data presentation device 101 specifies the designated image and transmits the image data to a projection device 102. COPYRIGHT: (C)2007,JPO&INPIT
