| 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. |
