Abstract: A conference system includes two or more user devices and an information processing apparatus connected communicably with each of the two or more user devices. The information processing apparatus receives first instruction data from each user device, generates display screen data representing a display screen including a virtual whiteboard displaying a displayed content changed based on the first instruction data, and sends the generated display screen data. Each user device displays the display screen indicated by the display screen data on a displaying unit. The display screen includes the virtual whiteboard displaying the displayed content indicated by generated display content data.
