Abstract

An apparatus, method, and computer program product are described below that can provide and/or detect dynamic fiducial markers presented on a display of an apparatus. An apparatus providing the fiducial marker may initially provide for the presentation of the fiducial marker on a display, where the fiducial marker represents one or more properties of the apparatus, such as connectivity information for the apparatus. The apparatus may modify the presentation of the fiducial marker based on a change in one or more properties of the apparatus. An apparatus configured to detect dynamic fiducial markers provided on other device displays may also be configured to provide for the presentation of its own fiducial markers, and vice versa. Thus, in some cases, apparatuses may function as both a tangible user interface display and a tangible object (e.g., in a bi-directional communication scenario).

Claims

1. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

receive an indication of a first fiducial marker presented on a display of a device proximate the apparatus;

execute a first operation based on the first fiducial marker;

receive an indication of a second fiducial marker presented on the display of the device, wherein the second fiducial marker is different from the first fiducial marker and replaces the first fiducial marker; and

execute a second operation based on the second fiducial marker.

2. The apparatus of claim 1, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to provide for presentation of a fiducial marker on the display of the apparatus, wherein the fiducial marker is representative of at least one property of the apparatus and is detectable by the device.

3. The apparatus of claim 2, wherein the presentation of the fiducial marker on the display of the apparatus is provided in response to the receipt of the indication of the first fiducial marker or the indication of the second fiducial marker presented on the display of the device.

4. The apparatus of claim 1, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to decode the indication of at least one of the first fiducial marker or the second fiducial marker.

5. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

provide for presentation of a fiducial marker on a display of the apparatus, wherein the fiducial marker is representative of at least one property of the apparatus; and

modify the presentation of the fiducial marker,

wherein the presentation of the fiducial marker is modified in response to a change in the at least one property of the apparatus.

6. The apparatus of claim 5, wherein the at least one property of the apparatus comprises at least one of a position, an orientation, an identity, or connectivity information of the apparatus.

7. The apparatus of claim 5, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to receive an indication of a fiducial marker presented on a display of a device proximate the apparatus.

8. The apparatus of claim 7, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to modify the presentation of the fiducial marker based on the indication received.

9. The apparatus of claim 5, wherein the fiducial marker includes steganographic information.

10. The apparatus of claim 5, wherein the display of the apparatus is a polarized display, such that the presentation of the fiducial marker on the display is dependent on an angle of the display of the apparatus with respect to a display of a device proximate the apparatus.

11. A method comprising:

receiving an indication of a first fiducial marker presented on a display of a device;

executing a first operation based on the first fiducial marker;

receiving an indication of a second fiducial marker presented on the display of the device, wherein the second fiducial marker is different from the first fiducial marker and replaces the first fiducial marker; and

executing a second operation based on the second fiducial marker.

12. The method of claim 11 further comprising providing for presentation of a fiducial marker on a display of an apparatus, wherein the fiducial marker is representative of at least one property of the apparatus and is detectable by the device.

13. The method of claim 11 further comprising decoding the indication of at least one of the first fiducial marker or the second fiducial marker.

14. A method comprising:

providing for presentation of a fiducial marker on a display of an apparatus, wherein the fiducial marker is representative of at least one property of the apparatus; and

modifying the presentation of the fiducial marker,

wherein the presentation of the fiducial marker is modified in response to a change in the at least one property of the apparatus.

15. The method of claim 14 further comprising receiving an indication of a fiducial marker presented on a display of a device proximate the apparatus.

16. The method of claim 14, wherein the fiducial marker includes steganographic information.

17. The method of claim 14, wherein the display of the apparatus is a polarized display, such that the presentation of the fiducial marker on the display is dependent on an angle of the display of the apparatus with respect to a display of a device proximate the apparatus.

18. A computer program product comprising at least one computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions for:

receiving an indication of a first fiducial marker presented on a display of a device;

executing a first operation based on the first fiducial marker;

receiving an indication of a second fiducial marker presented on the display of the device, wherein the second fiducial marker is different from the first fiducial marker and replaces the first fiducial marker; and

executing a second operation based on the second fiducial marker.

19. The computer program product of claim 18 further comprising program code instructions for providing for presentation of a fiducial marker on the display of the apparatus, wherein the fiducial marker is representative of at least one property of the apparatus and is detectable by the device.

20. The computer program product of claim 18 further comprising program code instructions for decoding the indication of at least one of the first fiducial marker or the second fiducial marker.

21. A computer program product comprising at least one computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions for:

providing for presentation of a fiducial marker on a display of an apparatus, wherein the fiducial marker is representative of at least one property of the apparatus; and

modifying the presentation of the fiducial marker,

wherein the presentation of the fiducial marker is modified in response to a change in the at least one property of the apparatus.

22. The computer program product of claim 21 further comprising program code instructions for receiving an indication of a fiducial marker presented on a display of a device proximate the apparatus.

23. The computer program product of claim 21, wherein the fiducial marker includes steganographic information.

24. The method of claim 21, wherein the display of the apparatus is a polarized display, such that the presentation of the fiducial marker on the display is dependent on an angle of the display of the apparatus with respect to a display of a device proximate the apparatus.
