Public Display Content Routing via Location Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small screens on devices like smartphones and tablets make it difficult to access and use information, especially for tasks like reading detailed maps, when users are on the move, as these devices are cumbersome and the content is not easily viewable in a larger format.
Innovation Solution
A system that allows content, such as map directions, to be requested from a mobile device and automatically presented on a nearby public display device, selecting the most appropriate display based on location and user preferences, without user input, ensuring the content is easily viewable and accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is viewed on mobile device screens, then portability and accessibility are improved, but viewing comfort and detail visibility deteriorate due to small screen size
Solution Approach 1:
The patent introduces a server as an intermediary between the mobile device and public display devices. The server receives content requests from mobile devices, identifies suitable public displays based on location and user preferences, and manages the content transmission. This intermediary enables seamless offloading of content viewing from small mobile screens to large public displays without requiring direct connection or user intervention.
Solution Approach 2:
The patent extracts the content presentation function from the mobile device itself and relocates it to external public display devices. By separating the content generation (on mobile device) from content presentation (on public display), the system allows users to maintain portability while enjoying large-format viewing on public infrastructure.
2Measurement precision
If users manually select display devices, then control and precision are improved, but operation complexity and time consumption increase
Solution Approach 1:
The system implements self-service by enabling public display devices to automatically identify and select themselves for content presentation. The displays broadcast their availability and characteristics, and the server automatically matches them with appropriate content requests based on location, user preferences, and display capabilities, eliminating the need for manual user selection.
Solution Approach 2:
The patent incorporates feedback mechanisms where public display devices provide information about their availability, location, and capabilities to the server. The server uses this feedback to automatically determine the most suitable display for each content request, ensuring accurate matching without user intervention. User preferences also provide feedback that refines the selection process.
3Area of stationary object
If content is presented on public display devices, then viewing comfort and detail visibility are improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent makes public display devices multi-functional by enabling them to serve both their original purposes and content presentation for mobile devices. The same display infrastructure is used for both public information/entertainment and for presenting user-requested content from mobile devices, eliminating the need for dedicated hardware and reducing overall system complexity.
Solution Approach 2:
The server acts as an intermediary that manages the complexity of coordinating between mobile devices and public displays. It handles location-based matching, user preference processing, and content routing, thereby shielding users from system complexity while enabling sophisticated content presentation on public displays.
4Ease of operation
If automatic display selection is implemented, then ease of operation and speed are improved, but loss of information about user preferences may increase
Solution Approach 1:
The system performs preliminary action by collecting and storing user preferences in advance. Before automatic display selection occurs, the server already has access to user preference data, which it uses to pre-filter and rank potential display options. This ensures that even though selection is automated, it is guided by stored user preferences, preventing information loss.

AI summary
Methods, systems, and media for presenting requested content on public display devices are provided. In some implementations a method for presenting content on a display device is provided, the method comprising: receiving a request from a mobile device to present content, including image data, on a display device; receiving a graphical representation associated with a user; receiving location information associated with the mobile device; receiving display device information associated with display devices, including location information associated with that display device; selecting, without user input, a first display device on which to present the content based on the location information associated with the mobile device and the location information associated with each of the plurality of display devices; and in response to selecting the first display device, causing both the graphical representation associated with the user of the mobile device and the content to be presented by the first display device.
