Predictive Suggestion Sorting by Operating Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing character input techniques on touchscreen devices fail to accurately reflect the user's situation during input operations, leading to inappropriate prediction results.
Innovation Solution
A character input device that includes an operation unit, a detector to measure operating speed, and a predictive suggestion generation unit that sorts suggestions based on the detected speed, ensuring output suggestions align with the user's input speed and situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If predictive suggestions are generated without considering operating speed, then the prediction function can be implemented simply, but the prediction accuracy and user convenience deteriorate
Solution Approach 1:
The system performs preliminary detection of operating speed before generating predictive suggestions. The detector measures the user's input speed in advance, and this information is used to adjust the prediction algorithm accordingly, ensuring accurate predictions matched to the user's actual typing pace
Solution Approach 2:
The prediction system dynamically adapts to the user's operating speed. The predictive suggestion generation unit adjusts its behavior based on real-time speed detection, making the system flexible and responsive to changing user input patterns rather than using a fixed prediction approach
2Adaptability or versatility
If predictive suggestions are sorted by frequency alone, then the sorting algorithm is simple, but the suggestions do not reflect the user's current input situation
Solution Approach 1:
The sorting criteria for predictive suggestions are changed based on the detected operating speed parameter. When typing speed is high, the system prioritizes shorter suggestions; when typing speed is low, it prioritizes longer suggestions. This parameter-based adaptation allows the system to flexibly adjust to different user situations
