Palm Verification Guidance via Dynamic Visual Distance Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current palm verification methods are inefficient due to their complexity, leading to low efficiency and increased user understanding costs, particularly in applications like door unlocking and payment systems.
Innovation Solution
A guiding method and apparatus that displays a guidance interface with a movable element in a moving region, dynamically adjusting its location based on the distance between the palm and the detection device, providing visual guidance for palm verification by indicating the correct distance, thus simplifying the verification process.

Engineering Contradiction Analysis
1Productivity
If traditional palm verification methods are used with complex operation guides, then verification accuracy can be maintained, but verification efficiency decreases and user understanding costs increase
Solution Approach 1:
The patent replaces complex mechanical guidance operations with an optical visualization system. A display screen shows a movable element that visually indicates the required palm movement trajectory and distance, substituting text-based mechanical instructions with intuitive visual feedback. This allows users to understand verification requirements immediately without complex operational guides.
Solution Approach 2:
The patent introduces a movable element as an intermediary between the user's palm and the detection device. This visual indicator serves as a mediator that translates complex verification requirements into simple visual cues, showing users exactly where to move their palm and how far, thereby reducing understanding costs while maintaining verification accuracy.
2Measurement precision
If detailed operation guidance is provided for palm verification, then verification accuracy is maintained, but user understanding costs increase
Solution Approach 1:
The patent utilizes visual changes in the display interface to convey verification status and guidance information. The movable element changes position, and different visual states indicate different verification stages, allowing users to understand requirements without text-based instructions. This visual language maintains precision while reducing information processing burden.
Solution Approach 2:
The patent transforms one-dimensional text instructions into two-dimensional visual displays. The movable element's position on the screen provides spatial information about palm movement requirements, encoding multiple pieces of information (direction, distance, status) in a single visual representation, thereby reducing user understanding costs while maintaining verification accuracy.

AI summary
A method for guiding palm verification performed by a computer device is disclosed. The method includes: displaying a guidance interface for palm verification, the guidance interface including graphical guidance information and the graphical guidance information comprising a movable element in a moving region, and a display location of the movable element in the moving region indicating a current distance between a palm and a detection device; dynamically adjusting the display location of the movable element in the moving region on the guidance interface in response to a change of the current distance between the palm and the detection device; and displaying first prompt information for indicating starting of verification or completion of verification when the display location of the movable element in the moving region meets a preset condition.
