A display apparatus includes a display section that displays an image containing one or more objects based on display image data on a display surface, a position generator that generates information representing the position of a mobile terminal that comes into contact with the display surface as terminal position information representing a terminal position in the image, an object identifier that identifies object data on an object corresponding to the terminal position based on the display image data and the terminal position information, and a transmitter that transmits the object data to the mobile terminal.
