Linked Display System for Cross-Device Information Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing both overview and detailed information simultaneously on mobile terminals due to limited display size, requiring complex operations to switch between different scales and amounts of information.
Innovation Solution
A linked display system comprising first and second display apparatuses that allow users to specify a position, transmitting a predetermined range for displaying reference information with different scales and amounts, optimizing the display by selecting appropriate information based on local display capacity and superimposing frames to indicate display ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If display area size is limited to guarantee portability, then portability is improved, but information availability deteriorates
Solution Approach 1:
The patent extends the display system from a single 2D screen to multiple display devices in 3D space. The first display apparatus (mobile terminal) and second display apparatus (external display) work together to provide both overview and detailed information simultaneously, effectively adding a spatial dimension to the display capacity.
Solution Approach 2:
The display information is segmented into two types: operation display information shown on the mobile terminal and reference display information shown on the external display. This segmentation allows different scales and amounts of information to be displayed simultaneously on different devices, resolving the contradiction between limited screen size and information availability.
2Loss of information
If user switches between different scales and amounts of information, then information availability is improved, but operation complexity increases
Solution Approach 1:
The first display apparatus acts as an intermediary between the user and the second display apparatus. It receives user input, transmits the predetermined range to the second display apparatus, and receives control signals back. This intermediary role simplifies user interaction by consolidating control operations on the mobile terminal while leveraging the external display's capacity.
Solution Approach 2:
The system merges the display capabilities of two separate devices to provide both overview and detailed information simultaneously. The operation display information and reference display information are combined in a coordinated manner, allowing users to access multiple information scales without switching displays or applications.
3Loss of information
If multiple information scales are displayed simultaneously, then information availability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the detailed reference display information from the mobile terminal and displays it on an external second display apparatus. This extraction reduces the processing and display burden on the mobile terminal while maintaining access to comprehensive information through the external display.

AI summary
Provided is a linked display system capable of improving availability of information having different scales and amounts of information, a linked display method, and a program. A mobile terminal 100 includes a display unit 101 that displays operation display information I1, a range setting unit 105 that sets a predetermined range A containing a specified position in accordance with an operation to specify any position P over operation display information and a communication unit 109 that transmits the predetermined range to a TV set 200. The TV set includes a communication unit 209 that receives the predetermined range from the mobile terminal, a display information selection unit 205 that selects reference display information I2 capable of displaying information corresponding to the predetermined range from at least one piece of the reference display information corresponding to the operation display information in accordance with display capacity of a local apparatus and having a different scale and amount of information from those of the operation display information, and a display unit 201 that displays information corresponding to the predetermined range of the selected reference display information.
