Abstract

An example processor-implemented method for placing a graphical element on a display surface in accordance with the present disclosure is receiving an image of at least part of a display surface, detecting in the received image a token placed by a user on the display surface to specify an area on the display surface, and placing the graphical element within the area specified by the placement of the token.

Claims

1. A processor-implemented method for placing a graphical element on a display surface, comprising:

receiving an image of at least part of a display surface;

detecting in the received image a token placed by a user on the display surface to specify an area on the display surface; and

placing the graphical element within the area specified by the placement of the token.

2. The method of claim 1, further comprising:

receiving a selection by the user of a graphical element item, wherein the graphical element item is selected from a set of graphical element items in the graphical element, and the graphical element item identifies an action to be performed; and

performing the action identified by the graphical element item.

3. The method of claim 2, further comprising:

receiving user data from the user;

retrieving a user profile associated with the user data, the user profile identifying a security level for the user; and

determining whether to perform the action identified by the graphical element item based on the security level.

4. The method of claim 1, wherein the display surface is horizontal and the token rests on the display surface.

5. The method of claim 1, further comprising:

identifying data associated with the token based on the received image; and

generating the graphical element based on the data.

6. The method of claim 5, wherein generating the graphical element based on the data further comprises:

checking the data for graphical element items;

if the graphical element items do not exist in the data, generating the graphical element with generic graphical element items; and

if the graphical element items exist in the data, using the graphical element items to generate the graphical element.

7. The method of claim 5,

wherein the data comprises at least one graphical element item and graphical element settings;

and

wherein generating the graphical element based on the data further comprises generating the graphical element based on the at least one graphical element item and graphical element settings.

8. The method of claim 5,

wherein the data comprises at least one graphical element item and graphical element settings;

and

wherein identifying the data associated with the token based on the received image further comprises;

examining the image of the token to recognize the token; and

obtaining the at least one graphical element item and graphical element settings associated with the recognized token.

9. The method of claim 1, wherein placing the graphical element within the area specified by the placement of the token further comprises:

identifying dimensions of the graphical element;

comparing the dimensions of the graphical element to the area specified by the placement of the token on the display surface;

if the dimensions of the graphical element are greater than the area specified by the placement of the token, adjusting the dimensions of the graphical element according to the area specified by the placement of the token; and

if the dimensions of the graphical element are equal to or less than the area specified by the placement of the token, maintaining the dimensions of the graphical element.

10. The method of claim 1, further comprising:

receiving user data from the user;

retrieving a user profile associated with the user data, the user profile identifying at least one graphical element item and graphical element settings; and

generating the graphical element based on the user profile using the at least one graphical element item and graphical element settings.

11. A projector-camera system for placing a graphical element on a display surface, comprising:

a projector for projecting an image received from a processor, wherein the projector has a field of projection on the display surface;

a camera for capturing an image of a token placed by a user on the display surface, wherein the camera has a camera field of view, and wherein the camera field of view intersects the projector field of projection of the projector on the display surface;

a memory storing data and instructions;

a processor disposed in communication with the memory, and configured to issue a plurality of processing instructions stored in the memory, wherein the processor issues instructions to;

receive an image of at least part of a display surface;

detect in the received image a token placed by a user on the display surface to specify an area on the display surface; and

place the graphical element within the area specified by the placement of the token.

12. The system of claim 11, wherein the processor:

identifies data associated with the token based on the received image; and

generates the graphical element based on the data.

13. The system of claim 12,

wherein the data comprises at least one the graphical element item and graphical element settings;

and

wherein the processor, in identifying the data associated with the token based on the captured image;

examines the image of the token to recognize the token; and

obtains the at least one graphical element item and graphical element settings associated with the recognized token.

14. The system of claim 11,

wherein the graphical element has a set of graphical element items,

wherein the set of graphical element items identify actions to be performed, and

wherein the processor:

receives a selection by the user of a graphical element item from the set of graphical element items; and

performs the action identified by the graphical element item.

15. The system of claim 14, wherein the processor:

receives user data from the user;

retrieves a user profile associated with the user data, the user profile identifying a security level for the user; and

determines whether to perform the action identified by the graphical element item based on the security level.

16. The system of claim 11, wherein the processor, in generating the graphical element based on the data:

checks the data for graphical element items;

if the graphical element items do not exist in the data, generates the graphical element with generic graphical element items; and

if the graphical element items exist in the data, uses the graphical element items to generate the graphical element.

17. The system of claim 11, wherein the processor:

receives user data from the user;

retrieves a user profile associated with the user data, the user profile identifying at least one the graphical element item and the graphical element settings; and

generates the graphical element based on the user profile using the at least one the graphical element item and the graphical element settings.

18. A non-transitory computer-readable medium comprising instructions that when executed cause a system to:

receive an image of at least part of an display surface;

detect in the received image a token placed by a user on the display surface to specify an area on the display surface; and

place the graphical element within the area specified by the placement of the token.

19. The non-transitory computer-readable medium of claim 18, wherein the instructions further comprise:

receiving a selection by the user of a graphical element item from the graphical element, wherein the graphical element has at least one graphical element item identifying an action to be performed; and

performing the action identified by the graphical element item.

20. The non-transitory computer-readable medium of claim 19, wherein the instructions further comprise:

receiving user data from the user;

retrieving a user profile associated with the user data, the user profile identifying a security level for the user; and

determining whether to perform the action identified by the graphical element item based on the security level.
