Description

This invention relates to a display device, a program, a display method, and a display system. Electronic whiteboards and other display devices are known that allow users to draw strokes on a touch-panel display using a dedicated electronic pen or their finger, and then display handwritten data formed by several strokes. Display devices with relatively large touch panels are installed in conference rooms and public facilities and used as electronic whiteboards by multiple users. Technologies have been devised to effectively utilize the limited display area of a display device (see, for example, Patent Document 1).
