Solution Overview

Problem

Current fingerprint recognition systems for personal identification and verification lack an efficient method for inputting actions into computer devices using fingerprint sensors, particularly when multiple fingers are involved.

Innovation Solution

A method and system utilizing a fingerprint recognition sensor on a user's thumb to read fingerprint patterns from other fingers, correlating these patterns with stored data to initiate specific actions on a computer device, allowing for flexible and secure input options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fingerprint sensor is used for personal identification, then security and accuracy are improved, but the ability to input diverse actions is limited

Engineering Contradiction:
Improveidentification accuracyVSAvoidaction input capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The fingerprint sensor is configured to perform multiple functions: it not only identifies users through fingerprint matching but also detects which finger is placed on it to trigger different actions. The sensor universally handles both authentication and command input by combining fingerprint verification with finger position detection, allowing a single device to serve multiple purposes without requiring separate input mechanisms

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple fingers are used for input, then action versatility is improved, but system complexity increases

Engineering Contradiction:
Improveaction input optionsVSAvoidsensor system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the input recognition process into two independent segments: fingerprint pattern recognition and finger position detection. The sensor array detects which specific finger (index, middle, ring, or pinky) is placed on the sensor, while separately verifying the fingerprint. This segmentation allows multiple fingers to trigger different actions without requiring a completely new system architecture, maintaining relative simplicity while enabling versatile input options

Inventive Principle:
Principle #1Segmentation

AI summary

A method of inputting an action to a computer device using a fingerprint recognition sensor placed on a thumb of a user. The method including: setting a plurality of actions corresponding to fingerprint data from a user's fingerprint patterns; storing the plurality of actions corresponding to the fingerprint data in the computer device; reading fingerprint data by the fingerprint recognition sensor corresponding to the user's fingerprint patterns from a first finger placed in contact with the fingerprint recognition sensor; comparing the fingerprint pattern from the first finger with the user's fingerprint data stored in the computer device; and responsive to a match between the fingerprint pattern from the first finger and the user's fingerprint data stored in the computer device, initiating the action stored in the computer device corresponding to the first finger placed in contact with the fingerprint recognition sensor.
