Abstract

An interactive system can include a display device, a control panel, a projector, a processing device, and an input device. The input device can detect indicia of its posture relative to the control panel or a display surface of the display device, so that the interactive system can recognize interactions between the input device and these components. Interactions between the input device and the display surface can be captured, analyzed by the processing device, and then represented in an image projected onto the display surface. The control panel can comprise a plurality of non-projected, tactile activation objects, each of which can correspond to an activity or function of the interactive system, such as, for example, powering on the projector. When the interactive system detects an interaction between the input device and an activation object, the activity corresponding to the selected activation object can be performed.

Claims

1. A presentation system comprising:

a processing device;

one or more activation objects, each activation object comprising a corresponding position-coding pattern and each activation object being mapped to a corresponding activity; and

a detection system configured to detect the position-coding pattern on an activation object with which an input device interacts, and to identify selection of a first activation object based on detection of a first position-coding pattern corresponding to the first activation object;

the processing device being further configured to transmit to one or more peripheral devices one or more instructions for performing the activity corresponding to the first activation object, in response to selection of the first activation object.

2. The presentation system of claim 1, the processing device or the input device being configured to map the first position-coding pattern to one or more coordinates.

3. The presentation system of claim 1, the processing device configured to receive indicia of the first activation object from the input device.

4. The presentation system of claim 3, the input device comprising an image-capture device for capturing an image of at least a portion of the position-coding pattern on the first activation object.

5. The presentation system of claim 4, the processing device or the input device being configured to map the portion of the position-coding pattern to the first activation object.

6. The presentation system of claim 3, the processing device being integrated into the input device.

7. The presentation system of claim 1, further comprising:

a display device having a display surface; and

a projector for projecting an image onto the display surface;

wherein the first activation object corresponds to a command to adjust one or more settings of the projector, and wherein the processing device transmits a signal to the projector in response to selection of the first activation object.

8. The presentation system of claim 7, the first activation object corresponding to a command to power on the projector.

9. The presentation system of claim 1, further comprising a display device having a display surface, the display surface having a second position-coding pattern thereupon, wherein the detection system is further configured to distinguish interactions between the input device and the display surface from interactions between the input device and the activation objects.

10. The presentation system of claim 9, the detection system being configured to determine coordinates on the display surface at which an interaction between the input device and the display surface occurs, based on detection of the second position-coding pattern.

11. The presentation system of claim 9, the activation objects being releasably securable to the display surface.

12. The presentation system of claim 9, the activation objects being integrated into the display device.

13. The presentation system of claim 1, at least one of the peripheral devices belonging to a group consisting of a projector, an audio system, a lighting system, HVAC, a disc player, and an automated projector screen.

14. The presentation system of claim 1, the first position-coding pattern comprising a pattern of dots.

15. A presentation system comprising:

a display device having a display surface with a first position coding pattern;

a peripheral device;

an activation object having a second position coding pattern, the activation object being associated with a first command related to the peripheral device;

an input device for detecting a local position-coding pattern indicating a current posture of the input device with respect to an object comprising the local position-coding pattern; and

a processing system configured to receive indicia of the current posture of the input device and, if the indicia indicates selection of the activation object, to transmit an instruction to the peripheral device to execute the first command.

16. The presentation system of claim 15, the processing system being external to the input device.

17. The presentation system of claim 15, the input device comprising an image capture device for capturing one or more images of the local position-coding pattern.

18. The presentation system of claim 15, the activation object being a non-projected object.

19. The presentation system of claim 15, the activation object being a tangible object.

20. A method comprising:

providing one or more activation objects and one or more position-coding patterns, each activation object having a corresponding position-coding pattern, and each activation object being associated with a corresponding command related to one or more hardware devices;

detecting a posture of an input device with respect to the activation objects, based on detection of at least one of the position-coding patterns;

identifying selection of a first activation object based on the posture of the input device; and

transmitting an instruction to at least one of the hardware devices to comply with the command associated the first activation object, in response to the selection of the first activation object.

21. The method of claim 20, wherein detecting a posture of the input device with respect to the activation objects comprises capturing an image of the at least one of the position-coding patterns.

22. The method of claim 20, the activation objects being tangible objects.

23. The method of claim 22, wherein transmitting the instruction to at least one of the hardware devices comprises transmitting the instruction to a projector to power on the projector.

24. The method of claim 20, wherein transmitting the instruction to at least one of the hardware devices comprises transmitting the instruction to at least one of a group consisting of a projector, an audio system, a lighting system, HVAC, a disc player, and an automated projector screen.

25. The method of claim 20, further comprising providing a display device having a display surface with a corresponding position-coding pattern.

26. The method of claim 25, further comprising determining toward which of the display surface and the first activation object the input device is directed.
