Abstract
Facilitating user actions between a media playback device and a separate personal device (e.g., a smartphone, smart watch, or wearable device) can present challenges. For example, methods that rely on shared user accounts may be less suitable for public or shared displays, while others, such as those using visual codes, can involve user actions that might interrupt a passive viewing experience. A data payload, such as a product identifier, can be embedded as an acoustic watermark into an audio signal broadcast from a source device. A separate receiving device can use its microphone to passively detect and decode this watermark from the ambient environment. Upon decoding the data payload, the receiving device can initiate a corresponding workflow, such as retrieving product information. This approach can facilitate a cross-device workflow by transferring context from a media consumption environment to a personal transactional device, potentially without depending on shared user accounts.
