Touch Screen Gesture Navigation Without Control Icons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch screens lack intuitive methods for users to navigate through sequentially arranged objects without control icons, leading to suboptimal usability.
Innovation Solution
An electronic device and method that allows users to navigate through sequentially arranged objects on a touch screen by detecting specific user inputs, displaying subsequent objects based on arrangement order when conditions are met, and designating alternative objects when conditions are not satisfied, without the need for control icons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control icons are provided on the touch screen for navigating objects, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent extracts the navigation function from traditional control icons and integrates it directly into the touch screen interface. The touch screen itself becomes the control mechanism through gesture recognition, eliminating the need for separate control icons while maintaining ease of operation.
Solution Approach 2:
The touch screen is given multiple functions: it serves both as the display medium for showing objects and as the control input device for navigating between objects. This multi-functionality eliminates the need for separate control icons, reducing device complexity while maintaining ease of operation.
2Adaptability or versatility
If multiple control icons are provided for different navigation functions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The touch screen interface provides universal gesture-based control that handles multiple navigation functions (forward, backward, selection) through different gestures on the same interface, eliminating the need for multiple specialized control icons.
Solution Approach 2:
The system changes the parameter of control input from discrete icons to continuous gesture parameters (swipe direction, swipe distance, touch position), enabling multiple navigation functions through variations of the same gesture type rather than requiring separate icons for each function.

AI summary
An electronic device is provided and includes a touch screen and a processor that is configured to display a first object among a plurality of sequentially arranged objects on the touch screen, display, when a first user input that satisfies a designated condition is detected via the touch screen while the first object is displayed, a second object arranged subsequent to the first object according to an arrangement order among the plurality of objects on the touch screen, and display, when a second user input that does not satisfy the designated condition is detected via the touch screen while the first object is displayed, a third object designated regardless of the arrangement order among the plurality of objects on the touch screen.
