Abstract
A display device is capable of switching a function of an indication body in accordance with the need of the user in the case in which the indication body is made to function as a pointing device. The display device is provided with a function device having a first interface. The configuration information of the first interface is stored in the storage section, and is supplied to a host device by a supply section via the function device. A change section is capable of change the configuration information in accordance with the operation of the user received by a reception section.
Claims12
A display device comprising:
- a function device connected to a host device, the function device having a first interface;
- a storage section adapted to store a plurality of pieces of configuration information including first configuration information adapted to make a first pointing device correspond to an interface;
- a display section adapted to display an image on a display surface;
- a detector adapted to detect a first position indicated by a first indication body to the display surface;
- a supply section adapted to assign the first configuration information stored in the storage section and first coordinate data representing the first position detected by the detector to the first interface, and supply the host device with the first configuration information and the first coordinate data via the function device;
- a reception section adapted to receive an operation of a user;
- and
- a change section adapted to change the configuration information corresponding to the first coordinate data in accordance with the operation received by the reception section.

- a third step of receiving an operation of changing the configuration information, which is assigned to the first interface, from a user;
- a fourth step of changing the configuration information corresponding to the coordinate data from the coordinate data supplied in the second step in accordance with the operation received in the third step;
- a fifth step of detecting, after the change in the fourth step, a position indicated by the indication body to the display surface;
- and
- a sixth step of assigning coordinate data representing the position detected in the fifth step and the configuration information changed in the fourth step to the first interface, and supplying the host device with the coordinate data and the configuration information via the function device.
