External Touch UI Mapping for Content Control Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in manipulating content on an electronic apparatus when a dedicated controller is unavailable, and using a virtual control UI on an external device can be cumbersome.
Innovation Solution
An electronic apparatus is equipped with a communication interface, display, and processor to transmit UI information to an external apparatus, allowing it to display a control UI and a guide UI based on user inputs, adjusting for size and location differences between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual control UI is displayed on an external apparatus when a dedicated controller is unavailable, then the user can manipulate content, but the user's touch engagement becomes difficult and the operation becomes cumbersome
Solution Approach 1:
The patent creates a visual copy of the control UI elements on the external apparatus display, showing buttons and controls that mirror the actual control interface. This allows users to see exactly where to touch on the external device, making the virtual control as intuitive as a physical controller. The control UI information is transmitted from the electronic apparatus to the external apparatus, enabling the user to view and interact with control elements remotely.
2Adaptability or versatility
If control UI information is transmitted to an external apparatus, then control functionality is enabled, but the complexity of coordinating UI output locations across different devices increases
Solution Approach 1:
The patent implements a feedback mechanism where the electronic apparatus receives information about the external apparatus's display characteristics and automatically adjusts the control UI output locations. The processor determines the appropriate output location on the external apparatus based on received display information, creating a closed-loop system that adapts to different device configurations without requiring manual coordination or increasing system complexity.
3Ease of operation
If a guide UI is displayed to show input location correspondence, then user interaction is enhanced, but the display information becomes more complex
Solution Approach 1:
The patent applies local quality by displaying the guide UI only in the specific region where control interaction is needed, rather than overwhelming the entire display. The guide UI is positioned at the corresponding input location on the electronic apparatus display, providing localized assistance exactly where the user needs it. This approach enhances user interaction while maintaining overall display clarity by limiting the additional information to necessary areas only.

AI summary
An electronic apparatus may include: a communication interface configured to communicate with an external apparatus; a display; at least one memory storing instructions; and at least one processor operatively connected to the at least one memory. The at least one processor may be configured to execute the instructions to: based on content being output on the display, transmit first user interface (UI) information corresponding to a UI related to control of the content to the external apparatus through the communication interface, control the display to output a first control UI together with the content based on the first UI information, and based on a user input being received through a second control UI output on the external apparatus based on the first UI information, control the display to output a guide UI in an input location corresponding to the user input together with the content and the first control UI.
