Abstract

Embodiments of the systems, devices, and methods described herein generally facilitate the display of a barcode at a computing device for capture by another computing device. In accordance with one example embodiment, a barcode is generated at a first computing device, the barcode is displayed on a display screen associated with the first computing device, and one or more display properties of the barcode are dynamically modified while it is displayed at the first computing device until the barcode is successfully captured (e.g. by a camera) at a second computing device.

Claims

1. A method of displaying a barcode at a computing device, wherein acts of the method are performed by a processor of the computing device, and wherein the method comprises:

generating a barcode for display on a display screen associated with the computing device;

displaying the barcode on the display screen;

generating a modified version of the barcode by modifying one or more display properties associated with the barcode;

displaying the modified version of the barcode; and

automatically repeating said generating the modified version and said displaying the modified version, until a signal to terminate display of the barcode is received by the processor.

2. The method of claim 1, wherein the one or more display properties comprise one or more colors in at least a part of the barcode.

3. The method of claim 1,

wherein the barcode comprises a first plurality of cells displayed in a first color and a second plurality of cells displayed in a second color;

and

wherein said modifying one or more display properties associated with the barcode comprises modifying at least one of;

the first color of the first plurality of cells, or the second color of the second plurality of cells.

4. The method of claim 3,

wherein the barcode is generated from a base pattern, and a layer having at least one modifiable property;

and

wherein said generating the modified version of the barcode comprises modifying one or more of the at least one modifiable property of the layer, and applying the layer to the base pattern.

5. The method of claim 4, wherein the at least one modifiable property of the layer comprises at least one of an opacity of the layer or a color of the layer.

6. The method of claim 4, wherein said one or more of the at least one modifiable property of the layer is modified based on a value of a time-dependent mathematical function.

7. The method of claim 6, wherein the time-dependent mathematical function comprises a continuous function.

8. The method of claim 7, wherein the time-dependent mathematical function comprises a sine function.

9. The method of claim 7, wherein the time-dependent mathematical function comprises a cosine function.

10. The method of claim 4,

wherein the first color is associated with positive values of a time-dependent mathematical function;

wherein the second color is associated with negative values of the time-dependent mathematical function; and

wherein a level of opacity is associated with an absolute value of the time-dependent mathematical function.

11. The method of claim 4, wherein at said repeating, the layer is modified from a transparent state to a semi-transparent state and back to the transparent state over time.

12. The method of claim 11, wherein at said repeating, the layer is modified from a transparent state to a semi-transparent state in the first color, then to the transparent state, then to a semi-transparent state in the second color, and then to the transparent state over time.

13. The method of claim 1, further comprising:

determining whether the signal to terminate display of the barcode is received; and

terminating display of the barcode upon determining that the signal to terminate display of the barcode has been received.

14. The method of claim 1, wherein the signal to terminate display of the barcode is received from a second computing device.

15. The method of claim 1, wherein the signal to terminate display of the barcode is received at the computing device when generated in response to a user input.

16. The method of claim 1, wherein the one or more display properties comprise a display size of at least a part of the barcode.

17. The method of claim 1, wherein the one or more display properties comprise an orientation of the barcode.

18. The method of claim 1, wherein the computing device comprises a mobile device.

19. A computing device comprising a processor and a memory, the processor configured to execute one or more application modules, said one or more application modules comprising:

a module configured to generate a barcode for display on a display screen associated with the computing device;

a module configured to display the barcode on the display screen;

a module configured to generate a modified version of the barcode by modifying one or more display properties associated with the barcode;

a module configured to display the modified version of the barcode; and

a module configured to automatically repeat said generating the modified version and said displaying the modified version, until a signal to terminate display of the barcode is received by the processor.

20. A computer readable storage medium comprising instructions that, when executed by a processor of a computing device, causes the processor to perform acts of a method of displaying a barcode, the method comprising:

generating a barcode for display on a display screen associated with the computing device;

displaying the barcode on the display screen;

generating a modified version of the barcode by modifying one or more display properties associated with the barcode;

displaying the modified version of the barcode; and

automatically repeating said generating the modified version and said displaying the modified version, until a signal to terminate display of the barcode is received by the processor.
