Ad Multi-Screen Collaboration via Wireless Signal Bearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public-oriented devices, such as electronic billboards, cannot implement cross-device multi-screen collaboration with user terminals due to the requirement of logging in with the same account.
Innovation Solution
An advertisement multi-screen collaboration method where an advertising device broadcasts a wireless signal with an identifier and bearing information, allowing a terminal to determine effective exposure and report an effective exposure event to a server, which updates user preferences and returns matching advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If public-oriented devices require login with the same account for cross-device multi-screen collaboration, then service continuity can be achieved, but device accessibility and user convenience deteriorate
Solution Approach 1:
The patent introduces a server as an intermediary that mediates between the advertising device and the terminal. The server receives bearing information from the advertising device, determines effective exposure, and manages user preferences without requiring direct account-based authentication between devices. This intermediary approach maintains service continuity while eliminating the need for users to manually log in to multiple devices.
2Reliability
If account-based authentication is required for multi-screen collaboration, then device identity verification is improved, but system complexity and user burden increase
Solution Approach 1:
The patent extracts the authentication and identity verification functions from the device-to-device interaction layer and relocates them to the server layer. The advertising device only needs to broadcast bearing information, while the server handles all identity verification, preference management, and coordination logic. This extraction simplifies the device complexity while maintaining reliable identity verification through server-based authentication.
3Measurement precision
If manual account configuration is required for each device, then user identity management is precise, but time consumption and operational efficiency deteriorate
Solution Approach 1:
The patent implements preliminary action by having the advertising device automatically broadcast bearing information containing device identifiers and location data before any user interaction occurs. The server pre-processes this information to establish device identities and user associations in advance. When a terminal approaches the advertising device, the server has already prepared the effective exposure determination and user preference data, eliminating the need for users to manually configure accounts on each device.

AI summary
An advertisement multi-screen collaboration method and a device are provided, and relate to the field of electronic devices, to resolve a problem that a public-oriented device and a terminal of a user cannot implement cross-device multi-screen collaboration. When playing a first advertisement, an advertising device broadcasts a wireless signal that includes an identifier of the first advertisement and bearing information used to indicate a position and an orientation of the advertising device. A first terminal receives the wireless signal, and when determining that the first advertisement played by the advertising device is effectively exposed to a user of the first terminal, sends an effective exposure event to a server. The effective exposure event includes a unified identity corresponding to the user of the first terminal and the identifier of the first advertisement, so that the server updates a historical preference of the user corresponding to the unified identity. The first terminal adds the unified identity when requesting an advertisement resource from the server, so that the server returns an advertisement resource of a second advertisement having a same advertising campaign as the first advertisement to the first terminal based on the unified identity.
