Remote Control Touch Screen UI Mirroring for Intuitive Cursor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls with touch screens require users to simultaneously monitor both the display apparatus screen and the remote control screen for input operations, leading to inconvenience and inaccurate manipulation due to size differences and the need to check multiple screens for cursor movement and input operations.
Innovation Solution
A remote control device with a controlling unit that identifies the user interface (UI) information corresponding to the cursor's location on the display apparatus screen and displays relevant UI elements on its own touch screen, such as list widgets, edit boxes, slide-bar widgets, button widgets, drop-down widgets, and scroll widgets, allowing intuitive and accurate manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control with a touch screen is used to control a display apparatus, then the user can view the screen on the remote control and move the cursor intuitively, but the user must check both the display apparatus screen and the remote control screen in turn, causing inconvenience and inaccurate manipulation
Solution Approach 1:
The patent applies the copying principle by displaying a replicated version of the display apparatus screen on the remote control touch screen. This copy shows the cursor position and UI elements, allowing the user to operate the remote control intuitively without needing to switch between viewing both screens simultaneously.
Solution Approach 2:
The remote control touch screen acts as an intermediary between the user and the display apparatus. It provides visual feedback about the cursor position and UI state, mediating the control operation so the user doesn't need to directly observe the display apparatus screen while manipulating the remote control.
2Volume of moving object
If the display unit size of the display apparatus is different from the remote control screen size, then the remote control can be compact and portable, but the user cannot perform manipulation accurately due to size differences
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the display parameters on the remote control touch screen based on the cursor position and UI context. The system changes what information is displayed (cursor coordinates, widget type, UI elements) to provide accurate manipulation feedback despite the size difference between the remote control screen and the display apparatus screen.
Solution Approach 2:
The patent applies local quality by displaying different types of information in different areas of the remote control screen based on where the cursor is located on the display apparatus. The display content is customized locally according to the specific UI context, providing precise manipulation feedback for the current cursor position while maintaining a compact form factor.

AI summary
A method for displaying a user interface (UI) of a display apparatus on a remote control and a remote control applying the same are provided. The remote control includes a controlling unit which identifies information regarding a UI where a cursor is located on a screen of the display apparatus, and a display unit, such as a touch screen, which displays an image corresponding to the identified UI information. Accordingly, a user may remotely control the display apparatus more intuitively and delicately using the touch screen display unit on the remote control.
