Handheld portable user device and method for the presentation of images
View Patent ↗A presentation system and a user device for use as a presentation aid is disclosed. The system comprises presentation means ( 5 ) for presenting images that associate with a presentation. Pointer means ( 4 ) are used for provision of a pointer on an image ( 11 ) presented by means of the presentation means. Detector means ( 8 ) are for detecting the pointer on the image and for determining the location of the pointer relative to the image. Control means ( 6 ) are adapted to provide at least one control function for the presentation based on information from the detector means.
1. A handheld portable user device for use by a presenter, comprising:
presentation means for presenting images that associate with a presentation;
detector means for detecting a pointer that has been provided on the image;
determination means for determining the location of the pointer relative to the image; and
control means adapted to provide at least one control function for the presentation based on information from the detector means.
2. A handheld portable user device according to claim 1 , which is a mobile telephone.
3. A presentation system, comprising:
a handheld portable user device comprising a presentation means for presenting images that associate with a presentation;
pointer means for providing a pointer on an image presented by means of the presentation means;
detector means for detecting the pointer and for determining the location of the pointer relative to the image; and
control means adapted to provide at least one control function for the presentation based on information from the detector means.
4. A system as claimed in claim 3 , wherein the handheld portable user device further comprises the detector means.
5. A system as claimed in claim 3 , wherein the handheld portable user device further comprises control means.
6. A system as claimed in claim 3 , wherein the handheld portable user device is adapted for wireless communication with at least one other station.
7. A system as claimed in claim 3 , wherein said presentation means are adapted to project images on a planar surface.
8. A system as claimed in claim 3 , wherein said presentation means comprises means for controlling an image presentation device.
9. A system as claimed in claim 3 , wherein at least two entities of the system are adapted for communication via a wireless interface.
10. A system as claimed in claim 9 , wherein the wireless interface is based on a short range radio link protocol or an infrared protocol.
11. A system as claimed in claim 3 , wherein the images are projected by means of a laser projector.
12. A system as claimed in claim 3 , wherein the images are presented by means of a display device.
13. A system as claimed in claim 3 , wherein the pointer means is adapted to provide a recognizable pattern on the image.
14. A system as claimed in claim 13 , wherein the detector means are adapted to detect said recognizable pattern.
15. A system as claimed in claim 3 , wherein the pointer means comprise a laser pointer.
16. A system as claimed in claim 3 , wherein the pointer means comprise a tipped element.
17. A system as claimed in claim 3 , wherein the detector means comprises imaging means.
18. A system as claim in claim 17 , wherein the imaging means comprise at least one camera.
19. A system as claimed in claim 17 , wherein the imaging means comprise at lease one scanning device.
20. A system as claimed in claim 17 , wherein the imaging means is adapted to track the location of the pointer provided by the pointer means.
21. A system as claimed in claim 17 , wherein the imaging means is adapted to track motion of the pointer on the image.
22. A system as claimed in claim 3 , wherein the detector means are adapted to detecting pointers provided by a plurality of pointer means.
23. A system as claimed in claim 22 , wherein at least two pointer means provide a different pointer on the image.
24. A system as claimed in claim 3 , wherein the user device comprises transceiver means for communication with a communication network.
25. A system as claimed in claim 24 , wherein the communication means provide a wireless communication interface between the user device and a cellular network.
26. A presentation system according to claim 3 , wherein the handheld portable user device is a mobile telephone.
27. A presentation method comprising:
presenting an image that associates with a presentation by means of a handheld portable user device comprising a presentation means;
producing a pointer on the image;
detecting the pointer from the image;
determining the location of the pointer relative to the image; and
controlling the presentation based on the determined location information.
28. A presentation method according to claim 27 , wherein the handheld portable user device is a mobile telephone.
