Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-computer interaction methods using touchscreen input face challenges such as joined-up handwriting difficulties and low input efficiency, particularly in controlling handwriting and vocal command directives.
Innovation Solution
A multi-modality human-computer interaction system that integrates touch operations and voice recognition to establish a correspondence between a user's voiceprint and a predetermined output position on a touchscreen, ensuring accurate and efficient input by matching voiceprints to determine the correct display location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touchscreen input is implemented by using touch operation, then handwriting input can be achieved, but joined-up handwriting and difficulty in controlling handwriting occur, causing low input efficiency
Solution Approach 1:
The patent replaces the mechanical touch operation system with a voice recognition system. Instead of using physical touch gestures that cause handwriting control difficulties, the system captures voice signals, processes them through voiceprint recognition, and converts them into text or commands. This substitution eliminates the joined-up handwriting problem and improves input efficiency by allowing users to speak naturally without worrying about stroke separation or gesture precision.
2Productivity
If voice command directives are used for input, then input efficiency can be improved, but interference from other users' voice inputs occurs, reducing reliability
Solution Approach 1:
The patent implements voiceprint recognition as a feedback mechanism to verify the source of voice inputs. When a voice command is detected, the system first performs voiceprint analysis to confirm whether the voice belongs to the authenticated user before executing the command. This feedback loop ensures that even in multi-user environments, only authorized voice inputs are processed, thereby maintaining high reliability while preserving the efficiency benefits of voice input.
3Adaptability or versatility
If multi-user voice input is allowed, then collaboration can be enhanced, but interference from other users' voice inputs occurs, causing incorrect display positions
Solution Approach 1:
The patent segments the voice input processing by creating distinct processing channels for different users based on their voiceprints. Each user's voice is independently identified and routed to their designated output position on the touchscreen. This segmentation allows multiple users to collaborate simultaneously without interference, as each user's voice inputs are clearly distinguished and displayed at the correct position, maintaining both multi-user adaptability and position accuracy.

AI summary
A human-computer interaction method and system, and an apparatus relate to the field of human-computer interaction technologies, to help output and display voice content of one or more users to a corresponding output position on a touchscreen, and improve touchscreen input efficiency and user experience. The human-computer interaction method includes: establishing a correspondence between a first voiceprint and a first output position on a touchscreen; and receiving first voice, and when it is determined that a voiceprint of the first voice matches the first voiceprint, recognizing content of the voice, and outputting and displaying the content to the first output position.
