Multi-Display Content Synchronization for Text Input and Supplemental Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interacting with content on a single, large display device, such as a digital television, can be cumbersome due to difficulties in providing textual input and accessing additional information, particularly due to readability and aesthetic concerns.
Innovation Solution
A networked environment is established using a primary display device and one or more secondary display devices, where the secondary devices provide synchronized supplemental content, such as on-screen keyboards or additional information, to enhance the user experience without interfering with the primary content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If content is displayed on a single large display device, then the display area is sufficient, but user interaction becomes cumbersome and additional information cannot be easily provided
Solution Approach 1:
The system divides the display functionality into multiple independent display devices. The primary display device shows main content while secondary display devices provide supplemental information and interaction interfaces. This segmentation allows each device to have optimized functionality, improving ease of operation while maintaining sufficient total display area.
Solution Approach 2:
The system extends the display experience from a single two-dimensional surface to multiple two-dimensional surfaces distributed in space. By adding secondary displays in different locations (e.g., mobile devices, tablets), the system creates a multi-dimensional display environment that provides both adequate display area and improved interaction capabilities.
2Loss of information
If supplemental information is provided on the same display, then information completeness improves, but readability and aesthetics deteriorate
Solution Approach 1:
The system segments information presentation across multiple display devices. Primary content is displayed on the main device with high visual quality, while supplemental information is displayed on secondary devices. This separation ensures that each display shows only its intended content at optimal quality, maintaining readability and aesthetics while providing complete information.
Solution Approach 2:
Secondary display devices act as intermediaries for presenting supplemental information. Instead of cluttering the primary display with additional data, the system uses secondary displays as intermediary surfaces that offload supplemental content, keeping the primary display clean and readable while still providing complete information to the user.
3Device complexity
If text input is provided through on-screen keyboard with remote control, then the device complexity remains simple, but ease of operation deteriorates
Solution Approach 1:
The system segments the text input function from the primary display device and relocates it to secondary display devices. The secondary devices (mobile phones, tablets) provide their own optimized keyboards and input interfaces, while the primary device maintains its simple remote control. This segmentation improves text input ease without increasing the complexity of the primary device.
Solution Approach 2:
Secondary display devices serve multiple functions: they display supplemental information, provide text input interfaces, and communicate with the primary display device. By making these devices multi-functional, the system avoids adding dedicated text input hardware to the primary device, maintaining simplicity while improving ease of operation.

AI summary
Disclosed are various embodiments for providing content via multiple display devices. First content is transmitted to a second computing device for rendering on a first display device. A current state of the first content rendered on the first display device is determined. A directive is sent to a third computing device to render second content that is synchronized to be relevant to the current state of the first content on a second display device corresponding to the third computing device. The second content comprises a list of cast members currently on screen in the first content.
