Sliding Candidate Character Box for Compact Device Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact smart devices have limited screen size, making existing input methods like handwriting, T9, and keyboard input impractical due to the small screen size, and voice input is inaccurate in noisy environments.
Innovation Solution
A character input method and apparatus that displays a character input box and a sliding candidate character box on the screen, allowing users to select characters by sliding and tapping, with features like intelligent prediction and language switching, enabling efficient character input independent of screen size and improving accuracy over voice input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact smart device is designed with a smaller screen size, then the device becomes more portable and compact, but existing input methods (handwriting, T9, keyboard) become difficult or impossible to use due to insufficient display area
Solution Approach 1:
The input interface is segmented into two distinct areas: a character input box area and a candidate character box area. The candidate character box can be positioned independently (first area or second area), allowing the interface to be divided into functional zones that optimize both display efficiency and user interaction on compact screens.
Solution Approach 2:
The patent utilizes spatial arrangement in different screen areas (first area vs. second area) to organize input elements. By distributing characters and candidate boxes across different spatial zones, the interface maximizes the use of limited screen real estate while maintaining accessibility and usability.
2Ease of operation
If the screen size is increased to fully display handwriting strokes, T9 keypad, or keyboard, then input methods become feasible, but the device loses its compact form factor
Solution Approach 1:
The input interface is segmented into two distinct areas: a character input box area and a candidate character box area. The candidate character box can be positioned independently (first area or second area), allowing the interface to be divided into functional zones that optimize both display efficiency and user interaction on compact screens.
Solution Approach 2:
The patent dynamically adjusts the positioning and display parameters of the candidate character box based on screen space availability. By changing the spatial parameters (positioning in first or second area) and display characteristics of input elements, the system adapts to different screen sizes while maintaining input functionality.
3Productivity
If voice input is used in noisy environments, then input speed may be maintained, but input accuracy deteriorates significantly
Solution Approach 1:
The system performs preliminary action by displaying multiple candidate characters before the user finalizes input. The candidate character box pre-presents possible character options based on partial input or context, allowing users to select from predetermined candidates rather than relying solely on voice recognition accuracy in noisy environments.
Solution Approach 2:
The patent implements feedback mechanisms where the system provides candidate character suggestions to the user based on their input. This feedback loop allows users to verify and correct potential input errors by selecting from displayed candidates, thereby improving overall input accuracy while maintaining efficient workflow.

AI summary
Embodiments of the present invention provide a character input method and apparatus, and a terminal. In the method, a candidate character box is a sliding display box that is capable of displaying a preset quantity of characters, a different candidate character is displayed in the candidate character box in response to a slide operation of a user, the candidate character box includes a selection box, and a candidate character in the selection box is selected, so as to implement information input on a compact smart device.
