Invisible optical label for transmitting information between computing devices

摘要

Embodiments of the present disclosure provide a method and system for sharing information between a first computing device and a second computing device. In the described embodiments, an optical label, such as, for example a QR code, is generated on the first computing device. In embodiments, the optical label is color encoded and displayed in such a way that the optical label is not perceptible to a user. The second computing device may capture the encoded optical label and subject the captured images to a processing technique that decodes the encoded optical label.

主权项

1. A method for transmitting information from a first computing device to a second computing device, the method comprising:
generating an optical label on the first computing device; generating a first frame of the optical label and a second frame of the optical label wherein:
a first portion of the first frame of the optical label is encoded in a first color and a second portion of the first frame of the optical label is encoded in a second color; anda first portion of the second frame of the optical label is encoded in a third color and a second portion of the second frame of the optical label is encoded in a fourth color; and alternately displaying the first frame and the second frame at a frequency such that the first color of the first portion of the first frame is offset by the third color of the first portion of the second frame and the second color of the second portion of the first frame is offset by the fourth color of the second portion of the second frame and wherein alternately displaying the first frame and the second frame at a frequency comprises alternately displaying the first frame and the second frame at a frequency at which the alternating frames are not perceptible by a human eye.
