Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems, such as tablet computers, lack efficient and intuitive methods for user input, particularly in scenarios where traditional keyboards are cumbersome or impractical.
Innovation Solution
The integration of fingerprint recognition technology, where touch sensors on the device's surface detect fingerprints and associate them with specific input functions, allowing users to perform actions like typing or navigating applications through fingerprint gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual keyboard is used for user input, then text input capability is provided, but ease of operation deteriorates due to cumbersome interaction
Solution Approach 1:
The patent combines fingerprint recognition technology with virtual keyboard functionality, merging biometric identification and input methods into a single integrated system. The fingerprint sensor is embedded within or adjacent to the display area, allowing simultaneous touch input and fingerprint detection, thereby simplifying user interaction while maintaining text input capability
Solution Approach 2:
The patent introduces fingerprint patterns as an intermediary between the user and the input system. Instead of directly pressing virtual keys, users place their fingerprint on the sensor, which then translates the fingerprint pattern into corresponding keyboard inputs, making the interaction more intuitive and easier to operate
2Ease of operation
If traditional keyboards are used, then text input is achieved, but usability deteriorates in scenarios where keyboards are impractical
Solution Approach 1:
The patent makes the input system universal by enabling multiple input methods through a single fingerprint sensor. The same sensor can recognize fingerprint patterns for text input, navigate applications, control media playback, and perform other functions, making the system adaptable to various usage scenarios without requiring separate physical keyboards
Solution Approach 2:
The patent implements dynamic input capabilities where the fingerprint sensor can adapt its function based on the context and user needs. The system can switch between different input modes (text input, navigation, media control) and adjust sensitivity or recognition parameters dynamically, enhancing usability across different scenarios
3Ease of operation
If fingerprint recognition is integrated, then intuitive user input is enabled, but device complexity increases due to additional sensors
Solution Approach 1:
The patent merges the fingerprint sensor with existing device components, such as integrating it into the display assembly or housing structure. This consolidation approach allows fingerprint recognition functionality to be added without significantly increasing overall device complexity, as the sensor shares space with or is coupled to existing structural elements
Solution Approach 2:
The fingerprint recognition system operates autonomously, automatically detecting and processing fingerprint patterns without requiring manual intervention or complex configuration. The system self-calibrates and adapts to different users, reducing the need for additional control mechanisms and simplifying the overall device architecture

AI summary
An information handling system includes a tablet computer, which in turn includes a touch sensor, a sensor detector, and a processor. The sensor detector is configured to communicate with the touch sensor, and to detect a first fingerprint on the touch sensor. The processor is configured to communicate with the sensor detector, to determine that the first fingerprint is within a first zone of the touch sensor, to match the first fingerprint to a stored fingerprint for the first zone of the touch sensor, to determine a first input function associated with the first fingerprint based on the first fingerprint matching the stored fingerprint for the first zone, and to execute the first input function.
