Abstract
Embodiments of the present invention provide time-varying barcodes in an active display for information exchange. Specifically, embodiments of the present invention provide a system and method for communicating information between electronic devices via a barcode image sequence. In a typical embodiment, a barcode image sequence is displayed on the display screen of a first electronic device. A second electronic device reads and decodes the barcode image sequence. The second electronic device displays an acknowledgement on the display screen of the second electronic device. The acknowledgement is read by the first electronic device.
Claims20
A data communication device for communicating information via an image, said device comprising:
- a display screen;
- a display component configured to display an image sequence or authentication graphic on the display screen;
- a camera configured to read the image sequence or an authentication graphic;
- a decoding component configured to decode the read image sequence;
- and
- a receiving component configured to receive the authentication graphic from the camera, wherein the device is configured to perform an alignment detection algorithm using the camera, the display, and the image sequence graphic or the authentication graphic.
The data communication device 1, wherein the device further comprises at least one of:
- a display resolution component configured to adjust image resolution based on a resolution calibration test, a display size component configured to adjust image size based on a size calibration test, and a display location component configured to adjust image location based on a location calibration test.
A method for communicating information via an image, comprising:
- displaying an image sequence on a display screen of a first electronic device;
- reading an image sequence by a camera of a second electronic device;
- decoding the read image sequence by the second electronic device;
- displaying an authentication graphic on the display screen of the second electronic device, the authentication graphic being generated in response to the image sequence;
- and
- performing an alignment detection algorithm using the authentication graphic as processed by the first electronic device.
A method for providing a data communication device for communicating information via an image, said method comprising:
- providing an electronic device, comprising:
- a display screen;
- a display component configured to display an image sequence or authentication graphic on the display screen;
- a camera configured to read the image sequence or an authentication graphic;
- a decoding component configured to decode the read image sequence;
- a receiving component configured to receive the authentication graphic from the camera, wherein the electronic device is configured to perform an alignment detection algorithm using the camera, the display, and the image sequence graphic or the authentication graphic.
