One of th...

In this paper we present CamTalk, a novel bidirectional communications framework using front-facing cameras and displays of smartphones. In the CamTalk framework, two smartphones exchange information via barcodes: information is encoded into barcodes that are displayed on the screen of the origin device, and those barcodes are captured by the front-facing camera of the destination device and de...
