Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human verification methods, such as CAPTCHAs, are becoming increasingly ineffective as computers become more advanced, necessitating a new approach to reliably distinguish humans from computers.
Innovation Solution
A capacitance module that communicates human-verification prompts, such as vibrations or light outputs, imperceptible to central processing units, and detects user responses to determine whether a human is operating the module, using a processor and user input detectors like capacitive sensors or pressure sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional CAPTCHA methods are used, then human verification is implemented, but computers with advanced capabilities can solve these CAPTCHAs, reducing verification effectiveness
Solution Approach 1:
The patent replaces traditional visual or text-based CAPTCHA challenges with a haptic feedback-based verification system. The mechanical vibration feedback delivered through the device's haptic motor creates a physical sensation that computers cannot perceive or replicate, thereby substituting the verification mechanism from cognitive processing to physical sensation processing.
Solution Approach 2:
The patent introduces haptic feedback as an intermediary between the verification system and the user. The haptic motor acts as a mediator that delivers tactile prompts to the user's finger, creating a physical interaction channel that bypasses computer-based visual or text processing and directly engages human sensory perception.
2Reliability
If hardware prompts like vibrations are used for human verification, then computers cannot perceive the prompts, but the solution relies on specific hardware and has limited use cases
Solution Approach 1:
The patent integrates the haptic verification system into an existing capacitive touch interface that is already present in modern devices. The same capacitive sensors and haptic motors used for normal touch interaction are repurposed for verification purposes, allowing the system to serve both regular operation and security verification functions without requiring separate dedicated hardware.
Solution Approach 2:
The patent combines the human verification functionality with the existing touch interface system. The capacitive sensing array and haptic feedback mechanisms that normally support user interaction are merged to also perform verification, creating a unified system where the verification process occurs through natural touch gestures rather than separate hardware components.

AI summary
Telling a human apart from a computer using a capacitance module may include receiving a request for human verification; determining a human-verification prompt; communicating the human-verification prompt using a prompting device in the capacitance module; detecting a response to the human-verification prompt using a user input sensor in the capacitance module; determining whether a human is operating the capacitance module based, in part, on the response detected with the user input detector; and returning a human verification result.
