Dynamic Aerial Image Positioning for Non-Contact Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact authentication techniques assume a fixed reading device, which limits adaptability to changing situations and environments, such as varying user positions or obstacles, potentially affecting authentication accuracy and security.
Innovation Solution
An information processing apparatus that dynamically adjusts an aerial image in the air to guide users to a specific position for non-contact authentication, considering user characteristics and environmental factors, using a processor-controlled system with a camera for image analysis and communication devices for directivity, allowing flexible authentication regardless of user position or obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed reading device is used for non-contact authentication, then the device structure is simple, but the adaptability to changing situations and environments is poor
Solution Approach 1:
The patent applies dynamics by making the aerial image position variable rather than fixed. The processor dynamically adjusts the position of the aerial image formed in the air based on detected user positions and environmental factors, allowing the authentication system to adapt to changing situations while maintaining a relatively simple fixed device structure.
Solution Approach 2:
The patent changes the parameter of image position dynamically. By varying the positional parameters of the aerial image based on user characteristics and environmental conditions, the system achieves high adaptability without requiring complex mechanical adjustments to the reading device itself.
2Measurement precision
If the aerial image position is fixed, then the system is simple to operate, but authentication accuracy decreases when user position varies
Solution Approach 1:
The patent implements feedback by detecting the user's position and environmental factors, then using this information to adjust the aerial image position. This closed-loop feedback mechanism ensures authentication accuracy is maintained across varying user positions without requiring users to manually adjust the system.
Solution Approach 2:
The system performs self-adjustment by automatically modifying the aerial image position based on detected conditions. The processor autonomously optimizes authentication accuracy without user intervention, maintaining ease of operation while improving measurement precision.
3Adaptability or versatility
If the reading device is fixed in position, then installation is simple, but it cannot accommodate obstacles or varying user positions
Solution Approach 1:
The patent applies dynamics by making the virtual authentication position flexible through aerial image relocation. The system detects obstacles and user positions, then dynamically repositions the aerial image to accommodate these conditions, allowing a fixed physical device to adapt to varying environments without complex reconfiguration.
