Touch Screen Portable Apparatus for External Display Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when browsing information on an external apparatus from a distance, as they need to alternately press directional buttons multiple times to navigate and select specific areas on the screen, which is inefficient.
Innovation Solution
A portable apparatus with a touch screen is connected to an external apparatus, allowing users to navigate and control information displayed on the external screen using intuitive gestures such as flicks, pinches, and taps, enabling swift and convenient browsing through synchronization and mode conversion based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote controller with directional buttons is used to browse information on an external apparatus, then the user can navigate the screen from a distance, but the user must press buttons multiple times alternately which causes inconvenience and reduces efficiency
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a touch screen interface that uses gesture recognition. Instead of physically pressing directional buttons multiple times, users can perform intuitive gestures (such as flicking, pinching, or tapping) on the touch screen to control the external apparatus, significantly reducing the number of operations required and improving browsing efficiency
Solution Approach 2:
The portable apparatus with touch screen acts as an intermediary between the user and the external apparatus. It receives user gestures through the touch screen, processes them, and transmits corresponding control signals to the external apparatus, enabling efficient remote control without direct interaction with the external device's interface
2Productivity
If multiple directional button presses are required to move the pointer to a specific area, then the pointer can reach the target location, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent substitutes the complex sequence of mechanical button presses with simple touch gestures on the portable apparatus's touch screen. A single flick gesture can move the pointer across large distances, and a pinch gesture can quickly zoom into specific areas, dramatically reducing both the number of operations and the time required to navigate to target locations
Solution Approach 2:
The system performs preliminary actions by automatically calculating the target location based on the user's gesture intent. When the user flicks or pinches on the touch screen, the system pre-computes the necessary pointer movements and zoom levels, then executes them directly without requiring the user to manually step through multiple button presses

AI summary
A portable apparatus comprising a touch screen for browsing information displayed on a screen of an external apparatus and a method for browsing information thereof are provided. The method includes displaying a link area included in the web page displayed on the screen of the external apparatus on the touch screen of the portable apparatus, in response to a first gesture of a user on the touch screen, magnifying the link area displayed on the touch screen, and in response to a second gesture of the user on the magnified link area transmitting information regarding displaying another web page related to the link area on the screen of the external apparatus from the portable apparatus to the external apparatus. Accordingly, users may browse information displayed on a screen of an external apparatus using a portable apparatus having a touch screen swiftly and conveniently.
