Fingerprint Detection for Touch Input Misinterpretation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch input mechanisms often misinterpret inadvertent contacts as legitimate input events, and increasing the number of gestures complicates user interaction, leading to frustration and disruption.
Innovation Solution
Incorporating a fingerprint detection module to enhance the interpretation of touch input events by identifying intended versus unintended actions and providing a nuanced understanding of finger contacts, allowing for more expressive gestures without complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the touch input mechanism is made more sensitive to accommodate more gestures, then the expressiveness of the input mechanism is improved, but the risk of misinterpreting inadvertent contacts as legitimate input events increases
Solution Approach 1:
The patent introduces fingerprint detection as an intermediary mechanism between the touch input and the system response. The fingerprint sensor detects whether a finger is intentionally touching the display, serving as a mediator that validates touch inputs and filters out inadvertent contacts before they are processed as legitimate gestures.
Solution Approach 2:
The patent replaces reliance on purely mechanical touch detection with biometric fingerprint detection. Instead of using only the physical presence of contact on the display surface, the system uses fingerprint pattern recognition to verify intentional user input, substituting a more reliable biometric detection method.
2Adaptability or versatility
If the number of valid gestures is increased to provide richer interaction, then the expressiveness of the touch input mechanism is improved, but it becomes more difficult for users to understand and memorize the gestures
Solution Approach 1:
The patent applies local quality by using fingerprint detection specifically at the point of contact on the display surface. Rather than requiring users to memorize complex global gesture sequences, the system locally verifies finger identity and intent at the touch point, simplifying the interaction model while maintaining rich gesture capabilities.
3Speed
If the touch input mechanism interprets all contacts as legitimate input events, then the responsiveness of the system is improved, but the frequency of inadvertent input events increases
Solution Approach 1:
The patent implements preliminary action by performing fingerprint detection before processing the touch input as a legitimate command. The system proactively checks for fingerprint presence and validates the touch intent before executing any gesture, preventing inadvertent inputs from triggering system responses.
Data Source
AI summary
A device and related methods, including a display and a display surface, are provided. The device includes logic configured to detect touch events received via the display surface. The display is coupled to a remote computing functionality that is configured to store shared work space information in a data store associated with the remote computing functionality to support collaborative tasks performed by participants in an interaction session. The device further includes logic configured to receive touch events and interpret the touch events as a request to drag an object, select a menu option, or display a web page. The device further includes logic configured to receive requests, not via the display surface of the display, but from user devices different from the display. Such requests can include requests to display an object on the display surface or execute an application.
