Digital Signage System Mobile Interaction via Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital signage systems lack interaction with viewers and are unable to provide information on viewing groups and frequencies, limiting advertising effectiveness, and integrated touch screens are costly and inconvenient, especially in public settings.
Innovation Solution
A digital signage system that allows users to interact through their mobile terminals, using a gateway device connected to a network with wireless access points, enabling content download and service provision to mobile devices, thereby extending service coverage without the need for multiple displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If integrated touch screens are used to provide interaction with viewers, then interactivity is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the viewer and the digital signage system. The mobile terminal handles all interaction operations (touch, input, display), while the digital signage system only needs to provide wireless network access and content delivery. This mediator approach eliminates the need for integrated touch screens in the display units, resolving the contradiction between interactivity and device complexity.
Solution Approach 2:
The patent makes the mobile terminal serve multiple functions: it acts as a touch interface, a display device, an input device, and a communication bridge. By leveraging the universal functionality of mobile terminals that users already possess, the system achieves comprehensive interactivity without adding specialized interaction hardware to each digital signage unit.
2Adaptability or versatility
If multiple integrated touch screens are deployed to serve multiple users simultaneously, then service coverage is improved, but cost increases significantly
Solution Approach 1:
The patent enables users to serve themselves using their own mobile terminals. Each user independently operates their personal device to interact with the digital signage system through wireless connection. This self-service model eliminates the need for the system to provide dedicated touch screens for each user, allowing unlimited concurrent users without increasing hardware costs.
Solution Approach 2:
Instead of physically replicating touch screen hardware for each user, the patent creates virtual copies of the interaction interface through wireless network connections. Multiple users simultaneously access the same digital signage content and interaction capabilities through their respective mobile terminals, achieving unlimited service coverage without physical hardware multiplication.
3Ease of operation
If integrated touch screens are used in public places, then interaction capability is improved, but ease of operation deteriorates due to privacy concerns
Solution Approach 1:
The mobile terminal serves as a privacy-protecting intermediary between the user and the public digital signage display. Sensitive operations (input, viewing private content) occur on the user's personal device rather than on the public display. The intermediary wireless connection transmits only necessary data, keeping personal information and interactions private while still enabling full interaction capability.
4Measurement precision
If face recognition technology and cameras are deployed to estimate advertising benefit, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a feedback mechanism where the system automatically tracks user interactions (viewing time, interaction frequency, purchase behavior) through wireless network data. This feedback loop provides continuous measurement of advertising effectiveness without requiring cameras or face recognition technology. The interaction data from mobile terminals serves as the measurement basis, simplifying the system while maintaining measurement capability.
