Dynamic Handwriting Input Waiting Time Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handwriting input systems in electronic devices, such as PDAs and smartphones, use fixed waiting times for handwriting recognition, which can lead to user inconvenience due to varying writing speeds, resulting in either wasted time or interrupted recognition processes.
Innovation Solution
The method dynamically adjusts the waiting time based on the writing speed of the user by generating a writing speed and setting the waiting time accordingly, ensuring that handwriting recognition is performed optimally without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed waiting time is set for handwriting recognition, then the system can perform recognition operations, but users with varying writing speeds experience either wasted time or interrupted recognition
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed waiting time to a dynamically adjustable waiting time that adapts to user writing speed. The system calculates writing speed based on the time interval between consecutive handwriting inputs and automatically adjusts the waiting time threshold accordingly. This allows the system to maintain reliable handwriting recognition for both fast and slow writers without causing time waste or recognition interruptions.
Solution Approach 2:
The patent implements parameter changes by modifying the waiting time parameter based on detected writing speed. The system changes the waiting time parameter dynamically according to the user's writing characteristics, rather than using a static parameter. This enables the system to optimize recognition performance across different writing speeds by adjusting the time threshold parameter adaptively.
2Productivity
If the waiting time is set for fast writers, then recognition completes quickly for them, but slow writers experience interrupted recognition processes
Solution Approach 1:
The system uses dynamics to make the waiting time adaptive rather than fixed. By continuously monitoring writing speed and adjusting the waiting time threshold in real-time, the system ensures that both fast and slow writers receive appropriate recognition timing, preventing interruptions for slow writers while maintaining efficiency for fast writers.
Solution Approach 2:
The system implements feedback by monitoring the time interval between consecutive handwriting inputs to calculate writing speed. This feedback mechanism allows the system to detect whether the user is writing quickly or slowly and adjust the waiting time accordingly, ensuring that recognition operations complete successfully for all writing speeds.
3Reliability
If the waiting time is set for slow writers, then recognition completes for them, but fast writers waste time waiting for recognition
Solution Approach 1:
The patent applies dynamics by making the waiting time parameter adaptive to individual user writing speeds. Instead of using a conservative fixed time that causes delays for fast writers, the system dynamically calculates the appropriate waiting time based on real-time writing speed detection, eliminating unnecessary waiting time while ensuring recognition completion for all users.
Solution Approach 2:
The system changes the waiting time parameter based on detected writing speed characteristics. For fast writers, the system reduces the waiting time parameter to minimize delays, while for slow writers, it increases the parameter to ensure complete recognition. This parameter adaptation resolves the contradiction between reliability and time loss.
4Ease of operation
If a default waiting time is provided, then the system can operate without user configuration, but it cannot adapt to individual writing speed variations
Solution Approach 1:
The system implements self-service by automatically detecting user writing speed and adjusting the waiting time parameter without requiring manual user configuration. The system serves itself by monitoring its own operational parameters (time between inputs) and adapting accordingly, eliminating the need for user setup while providing personalized adaptation to individual writing speeds.
Solution Approach 2:
The system uses feedback from user input patterns to automatically adapt to individual writing speeds. By monitoring the time intervals between consecutive handwriting inputs, the system receives feedback about the user's writing characteristics and adjusts the waiting time parameter accordingly, combining ease of operation with adaptability.

AI summary
A method for dynamically adjusting a waiting time of handwriting inputs is applied to an electronic equipment (100, 300, 700) having a handwriting input device (110). When a waiting-for-input time after the handwriting input device (110) receives a handwriting input (HIN) exceeds a waiting time of the electronic equipment, the electronic equipment (100, 300, 700) performs a handwriting recognition upon the handwriting input (HIN) so as to display a candidate word list (CL). The method includes the following steps: receiving the handwriting input (HIN); generating a writing speed according to the handwriting input (HIN); and setting the waiting time of the electronic equipment (100, 300, 700) according to the writing speed.
