Highlight-Driven Gesture UI Navigation via Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces, such as free cursor and highlight-driven UIs, lack efficient methods for navigating and selecting objects in a 2D or 3D screen space using gestures, particularly in applications where precise directional input is required.
Innovation Solution
Implementing a gesture-based system that recognizes neutral and directional hand gestures to move a highlight between adjacent objects on a display screen, where the direction and distance of the gesture input determine the movement speed and direction of the highlight, allowing for precise navigation and selection without the need for physical input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture-based input is implemented for highlight-driven UI navigation, then ease of operation is improved by eliminating physical input devices, but measurement precision deteriorates due to difficulty in detecting and measuring gesture directions and distances
Solution Approach 1:
The system displays visual feedback elements on the screen that show the detected gesture direction and distance relative to the current highlight position. This feedback mechanism allows users to see what the system has interpreted from their gestures, enabling them to adjust their gestures to achieve precise navigation. The feedback loop resolves the measurement precision problem by making the gesture detection process transparent and adjustable.
Solution Approach 2:
The patent replaces physical input devices (mechanical systems) with gesture-based input detected through computer vision or sensors. This substitution improves ease of operation by eliminating the need for physical devices, while the measurement precision challenge is addressed through software-based gesture analysis that tracks hand position, direction, and movement distance.
2Productivity
If gesture direction and distance are mapped to highlight movement, then productivity is improved by enabling faster navigation, but device complexity increases due to the need to process and interpret gesture signals
Solution Approach 1:
The gesture detection system is designed to handle multiple functions: detecting hand position, determining gesture direction, measuring movement distance, and mapping these to highlight navigation. This multi-functional approach improves productivity by enabling fast navigation through gestures, while the complexity is managed by integrating these functions into a unified gesture processing framework rather than separate systems.
3Measurement precision
If neutral position detection is required for gesture input, then measurement precision is improved by establishing a reference point, but ease of operation deteriorates due to the additional step of indicating neutral position
Solution Approach 1:
The system performs preliminary detection and indication of the neutral position before actual gesture navigation begins. By showing users where the neutral position is and what it looks like, the system prepares users for accurate gesture input. This preliminary action improves measurement precision by establishing a clear reference point, while the ease of operation is maintained by making the neutral position visually obvious and easy to identify.

AI summary
Disclosed are approaches for user interface control. In one embodiment, a method can include: indicating a highlight of a first object of a plurality of objects displayed on a display screen; accepting a signal deriving from a first gesture input of a user indicating a neutral position relative to the highlighted first object; accepting a signal deriving from a second gesture input of the user indicating a directional position at least a predetermined distance from the neutral position; and indicating, in response to the second gesture input, a movement of the highlight from the first object to a second object adjacent to the first object, and where the directional position of the second gesture input correlates to a position on the display screen of the second object relative to the first object.
