TV Interface Focus Control via Touch Gesture Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for TV interfaces are inflexible and tedious to navigate, requiring repeated button presses to move focus on complex interfaces, especially when many elements are present.
Innovation Solution
A method and system that uses a remote control device to generate movement events and paths, notifying a TV controller to determine the focus location, allowing continuous and complex directional movement of focus without repeated button presses, considering movement speed and sensitivity parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If directional buttons are used to control focus movement on TV interface, then the remote control structure remains simple, but the operation becomes tedious and time-consuming when there are many elements on the interface
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a touch-based system. The touch panel detects finger sliding movements and converts them into focus control signals, allowing users to move focus by simply sliding their fingers on the touch panel surface without repeatedly pressing physical buttons. This substitution dramatically reduces operation time and effort when navigating through multiple interface elements.
Solution Approach 2:
The patent introduces directional information through the dimension of movement trajectory on the touch panel. Instead of discrete button presses in four directions, the system captures the continuous sliding path of the finger, extracting directional components (up, down, left, right) from the trajectory. This dimensional approach allows for more intuitive and efficient focus navigation across the interface.
2Adaptability or versatility
If traditional directional buttons are used for focus control, then the remote control design remains simple, but the flexibility of focus movement is limited
Solution Approach 1:
The touch panel serves multiple functions: it acts as both the display interface and the control input device. The same touch panel surface that shows TV content also captures finger sliding gestures for focus control, eliminating the need for separate directional buttons. This multi-functionality increases focus movement flexibility while avoiding additional structural complexity in the remote control.
Solution Approach 2:
The system transitions from static button positions to dynamic touch gestures. The touch panel detects the dynamic sliding motion of the finger, capturing real-time directional information as the user moves their finger across the surface. This dynamic approach allows for flexible focus movement in any direction along the sliding path, adapting to the user's natural gesture rather than being constrained to fixed button directions.

AI summary
Provided are a method, apparatus and system for controlling a focus on a television interface. The method includes that a remote control device generates a movement event and a corresponding movement path and notifies a TV controller, and the TV controller determines the location of a moved focus according to the movement event and the movement path. Through the technology for controlling a focus on a television interface, a button can be pressed for reduced times, the focus can be controlled in any direction conveniently, quickly and flexibly, and the user experience can be improved effectively.
