Gesture-Based Interface with Dynamic Positional Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inexperienced users face difficulties in mastering gesture-based user interfaces due to repeated mistakes while learning gestures, as they lack immediate feedback and guidance during the learning process.
Innovation Solution
A gesture-based user interface method that detects input positions, determines available gestures, and displays guides on the screen, virtually divides the screen into regions to assign gestures, and updates guides based on input position changes, using a gesture input unit, processing unit, and display unit to provide real-time feedback through guide images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture-based user interface is implemented without real-time guidance, then device functionality is provided, but user learning difficulty increases and errors repeat
Solution Approach 1:
The system provides real-time feedback by detecting the user's current input position and displaying corresponding gesture guides that show what gestures can be performed from that position. This continuous feedback loop helps users learn correct gestures by immediately showing them the expected gesture paths, reducing repeated mistakes and improving ease of operation.
Solution Approach 2:
The system performs preliminary action by pre-calculating and displaying all possible gestures that can be input from the detected position before the user actually performs them. The guide images show gesture paths and destinations in advance, allowing users to plan and execute gestures more accurately without trial and error.
2Ease of operation
If gesture guides are displayed continuously, then user guidance is improved, but screen space for content is reduced
Solution Approach 1:
The gesture guides are implemented dynamically rather than statically. The guides are displayed only when the detection unit detects a specific input position, and they are updated in real-time as the user moves their input device. This dynamic approach ensures guidance is visible when needed while minimizing interference with content display during normal operation.
Solution Approach 2:
The guidance information is localized to the specific input position detected on the screen rather than being displayed globally. The guide images are positioned near the detected input location and only show gestures relevant to that area, allowing content in other regions of the screen to remain undisturbed and maximizing the effective content display area.
3Adaptability or versatility
If screen is divided into multiple regions with assigned gestures, then gesture organization is improved, but system complexity increases
Solution Approach 1:
The screen division system is designed to be universal and adaptable rather than fixed. The detection unit can identify input positions in any region, and the guide display unit can show appropriate gestures for any detected position. The system automatically adapts to different input positions without requiring complex manual configuration, making the multi-region system versatile yet simple to operate.
