Mobile Terminal IME Control for Simultaneous Multi-Display Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies have not effectively handled simultaneous input signals for both mobile terminals and display devices when they are connected and used simultaneously, leading to inefficiencies in user input management.
Innovation Solution
A mobile terminal with a wireless communication unit, a first display unit, and a controller that generates separate input processes for the terminal and a display device, allowing simultaneous output of input method editors (IMEs) to both units while maintaining seamless user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single input method editor (IME) is shared between mobile terminal and display device, then device complexity is reduced, but ease of operation deteriorates when multiple displays are used simultaneously
Solution Approach 1:
The patent divides the input process into separate first and second input processes, with each process dedicated to a specific display device. This segmentation allows each display to have its own IME instance, enabling simultaneous input operations without conflict while maintaining manageable complexity through clear process separation.
Solution Approach 2:
The mobile terminal is designed to universally support multiple input processes that can be simultaneously executed. The controller can manage multiple IMEs across different display devices, making the system capable of handling various input scenarios (single display, multiple displays, different user inputs) through a unified multi-process architecture.
2Ease of operation
If separate input processes are generated for mobile terminal and display device, then ease of operation improves for simultaneous input, but device complexity increases
Solution Approach 1:
The patent segments input processes into distinct first and second input processes, each associated with specific display devices. This segmentation enables simultaneous input operations without conflict while maintaining manageable complexity through clear process separation and dedicated resource allocation.
Solution Approach 2:
The patent introduces a new dimension of input process management by creating parallel input processes that operate independently yet coordinate through the controller. This dimensional expansion from single-process to multi-process architecture enables simultaneous input capability while organizing complexity through structured process layers.
3Adaptability or versatility
If input method editor is output to display device, then adaptability improves for multi-display usage, but loss of information increases due to input signal routing conflicts
Solution Approach 1:
The patent segments input signal routing into separate pathways for first and second input processes. Each display device receives input signals through its dedicated IME instance, preventing routing conflicts and information loss while maintaining high adaptability for multi-display configurations.
Solution Approach 2:
The controller acts as an intermediary that coordinates between multiple input processes and display devices. It manages the routing of input signals, ensuring that each input is correctly directed to the appropriate IME and display device, thereby preventing information loss while enabling versatile multi-display support.

AI summary
A mobile terminal and a method of controlling the mobile terminal are discussed. The mobile terminal includes a wireless communication unit configured to communicate with a display device external to the mobile terminal, a first display unit, and a controller configured to control the wireless communication unit and the first display unit. The controller generates a first input process and a second input process different from the first input process. Further, in response to the second input process, the controller receives a user input signal from the display device, and outputs a second input method editor (IME) for displaying on a second display unit of the display device.
