Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with touchscreens face inefficiencies in distinguishing between different types of touch inputs, such as drawing and external device control inputs, requiring users to manually switch modes, which is inconvenient.
Innovation Solution
An electronic apparatus that recognizes touch inputs based on their thickness, automatically determining whether they are drawing inputs or external device control inputs, eliminating the need for manual mode switching by using threshold ranges to differentiate between input types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electronic apparatus uses a single touch input mode for both drawing and external device control, then the device complexity is reduced, but the ease of operation deteriorates because users cannot easily distinguish between input types
Solution Approach 1:
The patent changes the parameter of touch input characteristics by analyzing multiple parameters simultaneously (contact area, pressure, duration, movement pattern) to distinguish between drawing inputs and external device control inputs. This allows the system to automatically differentiate input types without requiring users to manually switch modes, resolving the contradiction between simplified device operation and accurate input recognition.
2Measurement precision
If the electronic apparatus manually switches between drawing mode and external device control mode, then the measurement precision of input type recognition is improved, but the loss of time increases due to manual mode switching
Solution Approach 1:
The system performs self-service by automatically analyzing touch input characteristics and determining the input type without user intervention. The processor autonomously evaluates multiple parameters (contact area, pressure, duration, movement) and switches modes based on the analysis, eliminating manual mode switching and the associated time loss while maintaining accurate input type recognition.
Solution Approach 2:
The system implements feedback by continuously monitoring touch input parameters and adjusting the operating mode based on real-time analysis. The processor uses the feedback from parameter analysis to automatically determine whether the user intends to draw or control an external device, enabling rapid and accurate mode switching without manual user actions.
3Reliability
If the electronic apparatus analyzes multiple touch input parameters, then the reliability of input type differentiation is improved, but the device complexity increases
Solution Approach 1:
The processor is designed with multi-functionality to handle multiple touch input parameters simultaneously. It can analyze contact area, pressure, duration, and movement patterns using the same hardware components, avoiding the need for separate dedicated systems for each parameter. This universal approach improves input type differentiation reliability while minimizing the increase in device complexity.
