Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems that support both voice input and pen input are often confusing for users, requiring complex modality switching and relying heavily on user interfaces, which hinders productivity and efficiency in text editing tasks.
Innovation Solution
A computer system that integrates voice and pen input using a touchscreen device and an electronic pen, allowing for seamless switching between handwriting recognition, voice recognition, and formatting options through pressure signals and intuitive gestures, eliminating the need for complex UI-dependent modality switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex modality switching routines and UI-dependent functions are used to support both voice input and pen input, then the system can provide multiple input methods, but the user interface becomes confusing and input efficiency decreases
Solution Approach 1:
The system automatically detects the user's input modality through pressure sensors in the electronic pen, eliminating the need for manual mode switching. The pen naturally serves as both a pointing device and an input trigger, with different pressure thresholds automatically activating handwriting recognition or voice input without user intervention in modality selection.
Solution Approach 2:
The patent removes the complex UI-dependent modality switching routines from the system. Instead of relying on button presses, menu selections, or interface switches, the system extracts modality selection to the physical act of using the pen itself through pressure detection, simplifying the user interface to purely natural interactions.
2Ease of operation
If pressure sensors within the electronic pen are used to activate different modalities, then modality switching becomes simpler and more intuitive, but the device complexity increases
Solution Approach 1:
The electronic pen is designed to perform multiple functions through a single component addition - pressure sensing. The same pen structure serves as both a pointing device and a modality switch, with pressure thresholds triggering different input modes (handwriting vs. voice). This multi-functionality approach avoids adding separate switching mechanisms while maintaining simplicity.
3Productivity
If voice input is used for text entry, then input speed increases significantly, but accuracy decreases for certain text editing tasks requiring precision
Solution Approach 1:
The system dynamically switches between voice input and handwriting recognition based on the task context and user actions. During voice input, the system maintains high-speed text entry, but when the user applies pressure or uses pen gestures, it transitions to handwriting mode for precise editing tasks. This dynamic adaptation allows the system to optimize for speed during dictation and precision during editing without compromising either capability.
Data Source
AI summary
Systems and methods of text editing are disclosed. A system may include a touchscreen, a memory, and a processor. A method may include receiving, from an electronic pen in communication with the processor, pressure signals indicating a detection of a first amount of pressure at a pen tip. In response to receiving the pressure signals, handwriting recognition may be activated. Touch input representing handwriting a first location of the touchscreen may then be received, and the touch input may then be converted into rendered textual content corresponding to the handwriting.
