CROSS-DEVICE INFORMATION EXCHANGE VIA WEB BROWSER

摘要

Techniques are disclosed for exchanging information between devices. Each device is configured to execute a web browser application. One of the devices is referred to as a streamer device, and the other a receiver device. The receiver device includes a camera for receiving images displayed by the streamer device. A user of the streamer device can orient the display of the streamer towards the camera of the receiver device. The receiver device uses the camera to observe images displayed by any streamer devices that are present within the field of view of the camera. The receiver device, via the camera, analyzes each video frame displayed by the streamer device for a pattern. If the pattern is detected and matches a predefined pattern, the receiver device can retrieve information associated with the pattern, and display that information in the web browser.

主权项

1. A computer-implemented method comprising:
receiving, by a first device via a camera, a series of video frames generated by a web browser of a second device, the series of video frames having an image pattern steganographically hidden therein during playback such that the image pattern is visually imperceptible by a human when the video frames are rendered sequentially; analyzing, by a processor of the first device, the video frames to locate the image pattern; matching, by the processor, the image pattern with a predefined image pattern; and in response to the matching, displaying information associated with the predefined image pattern.
