Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile terminals face inconvenience due to excessive and elaborate touch gestures required when navigating magnified or reduced screen content, leading to dizziness and inefficient information retrieval.
Innovation Solution
A method for screen change control based on input signals that adjusts screen change speed and magnitude according to current screen ratio information, allowing for adaptive screen adjustments to facilitate easier information location without dizziness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If screen content is magnified by zooming in, then detail viewing capability is improved, but the number of touch gestures required to locate information increases
Solution Approach 1:
The patent implements dynamic adjustment of screen change magnitude based on current zoom level. When zoomed in, the system automatically reduces the magnitude of screen changes in response to touch gestures, allowing users to navigate detailed content without requiring excessive gestures. This dynamic adaptation resolves the contradiction by making the interface responsive to the current viewing state.
Solution Approach 2:
The system changes the parameter of screen change magnitude based on zoom level. At higher zoom levels, smaller screen changes are applied per gesture, while at lower zoom levels, larger screen changes are applied. This parameter adaptation allows the same touch gesture to be effective across different magnification states, reducing the total number of gestures needed.
2Area of stationary object
If screen content is reduced by zooming out, then overview capability is improved, but the elaboration of touch gestures required increases
Solution Approach 1:
The system dynamically adjusts screen change magnitude based on zoom level. When zoomed out to provide overview, the system increases the magnitude of screen changes in response to touch gestures, allowing users to navigate large areas efficiently without elaborate gesture sequences. This dynamic response adapts the interface to the current viewing context.
Solution Approach 2:
The patent implements parameter changes in screen change magnitude according to zoom level. At lower zoom levels where overview is needed, larger screen changes are applied per gesture, enabling efficient navigation across extended content areas without requiring elaborate touch gesture sequences.
3Productivity
If screen change magnitude is increased to reduce navigation gestures, then navigation efficiency is improved, but user dizziness increases
Solution Approach 1:
The system implements parameter changes in screen change magnitude based on zoom level. At higher zoom levels where detail viewing is prioritized, smaller screen change magnitudes are applied to prevent user dizziness. At lower zoom levels where overview is needed, larger magnitudes are acceptable. This contextual parameter adjustment optimizes navigation efficiency while preventing harmful effects.
Solution Approach 2:
The patent applies different screen change magnitudes locally based on zoom context. Instead of using a uniform screen change magnitude across all zoom levels, the system adapts the magnitude to the local viewing context, using smaller changes when zoomed in and larger changes when zoomed out. This local adaptation prevents dizziness during detailed viewing while maintaining navigation efficiency during overview.

AI summary
A screen change control method based on input signals and a mobile terminal supporting the same are disclosed. The mobile terminal includes a display panel for outputting a screen assigned to a user function, and a control unit for collecting screen ratio information based on at least one of a proportion of a current screen on the display panel to a full screen assigned to the user function and a ratio of enlargement or reduction by zooming, and for automatically adjusting an amount of screen changes for an input signal according to the screen ratio information.
