DISPLAY DEVICE, DISPLAY SYSTEM, AND DATA SUPPLY METHOD FOR DISPLAY DEVICE

摘要

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.

主权项

1. A display device comprising:
a function device connected to a host device and having a first interface and a second interface; a display section adapted to display an image on a display surface; a detector adapted to discriminate between a first pointing body and a second pointing body for pointing to a position on the display surface, and detect a first position pointed to by the first pointing body and a second position pointed to by the second pointing body on the display surface; and a supply section adapted to assign first coordinate data representing the first position detected by the detector to the first interface and supply the host device with the first coordinate data via the function device, and assign second coordinate data representing the second position detected by the detector to the second interface and supply the host device with the second coordinate data via the function device, wherein the first pointing body and the second pointing body are external to the display device and the display surface.
