Abstract

The invention relates to a method of giving a presentation on a wireless projector (1) from a mobile device (3). If the mobile device (3) has access to a company'"'"'s internal network (6), a wireless communications connection is made to the projector (1) over this network (6), thus enabling access to be gained to the data present there. If on the other hand the mobile device (3) belongs to a visitor who does not have access to the network (6), only an ad-hoc connection is made between the device (3) and the projector (1) without the network (6) being involved.

Claims

1. A system for giving a presentation, comprising

a) an image-showing device (1) having a wireless communications interface (2),

b) a mobile device (3) having a wireless communications interface (4), the image-showing device (1) and the mobile device (3) being arranged

c) to make an ad-hoc wireless connection in response to a triggering event,

d) to convey the further communication over a network (6) if one is accessible to both parties,

e) to show a presentation controlled by the mobile device (3) on the image-showing device (1).

2. A system as claimed in claim 1, characterized in that the image-showing device is a projector (1).

3. A system as claimed in claim 1, characterized in that the triggering event is the coupling of the mobile device (3) to a data carrier (5), which latter preferably contains the communications parameters required for the ad-hoc connection.

4. A system as claimed in claim 3, characterized in that the connection between the image-showing device (1) and the mobile device (3) is brought to an end when the coupling of the mobile device (3) to the data carrier (5) is interrupted.

5. A system as claimed in claim 3, characterized in that the data carrier is an insertable card (5) or a CD-ROM.

6. A system as claimed in claim 1, characterized in that the image-showing device (1) offers the mobile device (3) controlled access to resources on a network (6) accessible to the image-showing device, and in particular to printers (9) connected into the network.

7. A method of giving a presentation, comprising the following steps:

a) making of an ad-hoc wireless connection between a mobile device (3) and an image-showing device (1),

b) checking whether a common network (6) is accessible to the mobile device (3) and the image-showing device (1), and if required changing the communication over to a connection over the network,

c) control of a presentation on the image-showing device (1) by the mobile device (3).

8. A method as claimed in claim 7, characterized in that, in the check, it is established whether the mobile device (3) already has a connection to a common network (6)

9. A method as claimed in claim 7, characterized in that, if it is not being used for a presentation, the image-showing device (1) goes to a mode in which it is ready to make an ad-hoc connection.

10. A method as claimed in claim 7, characterized in that information is transmitted from the mobile device (3) over an ad-hoc connection to the image-showing device (1) and is conveyed by the latter to a network (6) for further processing, and in particular for printing out.
