A display device can make it possible to easily recognize a plurality of indication bodies as a plurality of pointing devices. The display device is provided with a function device having a first interface and a second interface, and stores configuration information assigning the same class to the first interface and the second interface in a storage section. The display device detects a first position indicated by a first indication body to a display surface and a second position indicated by a second indication body to the display surface, assigns first coordinate data representing the first position to the first interface, assigns second coordinate data representing the second position to the second interface, and supplies a host device with the first coordinate data and the second coordinate data.
