Adaptive Sensing Component Resolution for Touch Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods in computing devices, such as password entry or fingerprint scanning, can be time-consuming and detract from usability, leading to frustrating user experiences due to their inherent inefficiencies.
Innovation Solution
The implementation of an adaptive sensing component that dynamically changes resolution based on touch location, allowing for high resolution fingerprint sensing only when necessary, thereby reducing power consumption and enhancing user interaction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution sensing is continuously activated for authentication, then authentication accuracy is improved, but power consumption increases
Solution Approach 1:
The sensing component dynamically adjusts its resolution based on operational context. The system transitions between low resolution mode (for general touch detection) and high resolution mode (for fingerprint authentication), optimizing power consumption while maintaining authentication accuracy when needed
Solution Approach 2:
The sensing component changes its resolution parameter adaptively. By modifying the sensing resolution from low to high based on detected touch patterns and authentication requirements, the system achieves accurate fingerprint authentication only when necessary, reducing overall power consumption
2Reliability
If authentication steps are implemented, then security is improved, but user experience deteriorates due to time consumption
Solution Approach 1:
The system performs preliminary touch detection at low resolution before initiating high resolution fingerprint scanning. This preliminary action quickly identifies authentication intent and prepares the system, reducing the overall authentication time while maintaining security
Solution Approach 2:
The sensing component uses periodic sampling at different resolutions. Initial periodic samples detect touch presence, followed by targeted high resolution scanning only when authentication is required, streamlining the authentication process
3Measurement precision
If high resolution sensing is used across the entire display, then detection precision is improved, but device complexity increases
Solution Approach 1:
The sensing component implements local quality by maintaining high resolution sensing capability only in specific regions or zones where authentication is detected, rather than across the entire display. This reduces overall device complexity while preserving detection precision where needed

AI summary
A display component (108) displays multiple icons that a user can touch. A sensing component (104) supports multiple resolution modes, including at least a high resolution mode and a low resolution mode. In one embodiment, in response to detecting an object touching one of the multiple icons while in the low resolution mode, at least a portion of the sensing component over the touched icon changes to operating in a high resolution mode. While in the high resolution mode, the user's fingerprint is sensed, and then the sensing component is returned to the low resolution mode. In another embodiment, icons are displayed in different regions of a display, and those different regions are associated with different sensing component resolutions. When an icon is touched, the touch is detected by the sensing component using the sensing component resolution associated with the region that includes the icon.
