Abstract: An information processing apparatus includes an analysis unit, a starting point determination unit, and a coordinate conversion unit. The analysis unit analyzes an action history of a first subject, in accordance with action information obtained by detecting an action of the first subject. The starting point determination unit determines a position of a starting point of an action of the first subject, in accordance with the action history analyzed by the analysis unit. The position of the starting point is represented as a relative coordinate position. When a second subject different from the first subject has an absolute coordinate position, the coordinate conversion unit converts the relative coordinate position representing the starting point of the action of the first subject into an absolute coordinate position, in accordance with the absolute coordinate position of the second subject.

Abstract: A writing control system includes a display holding medium, a reading unit, an identifying unit, a control unit and a writing unit. The display holding medium includes a display section capable of displaying and holding an image in a no-power state and a storage section having a storage area for storing information that identifies an electronic document associated with it. The reading unit reads the information from the storage section when the display holding medium is located in a predetermined position. The identifying unit identifies the electronic document associated with the display holding medium, based on the information read from the display holding medium. When the electronic document associated with the display holding medium is not identified, the control unit performs control so that a page image, which has not been written, of an electronic document, which is used in last image writing, is set as a writing target.
