Word Prediction Selection via Single-Tap Keyboard Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current text input methods on electronic devices, such as smartphones and tablets, while improved with word prediction algorithms, still require multiple interactions to select predicted words, which can slow down the entry process.
Innovation Solution
A method that allows users to select word prediction candidates with a single tap on a key, utilizing a keyboard and touchscreen interface to generate and display candidates based on initial input characters, enabling quick selection without the need for additional keystrokes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If word prediction algorithms are used to suggest words during input, then data entry speed and accuracy are improved, but the number of interactions required to select predicted words increases
Solution Approach 1:
The system performs preliminary action by pre-computing and displaying multiple word prediction candidates along with their associated key sequences before the user needs to select a word. This allows the user to quickly identify and select the desired word without requiring multiple sequential interactions, thereby resolving the contradiction between productivity and ease of operation.
2Measurement precision
If multiple keystrokes are required to select predicted words, then selection accuracy is improved, but time consumption increases
Solution Approach 1:
The system implements feedback by displaying visual indicators (such as underlined characters) that show which predicted word corresponds to which key sequence. This feedback mechanism allows users to quickly and accurately identify the correct word without requiring multiple keystrokes, thus reducing time consumption while maintaining selection accuracy.
3Productivity
If traditional word selection methods are used, then keyboard simplicity is maintained, but input efficiency decreases
Solution Approach 1:
The system applies universality by making the keyboard serve multiple functions: not only for typing characters but also for selecting predicted words through single-tap interactions. The keyboard becomes a multi-functional interface that combines input and selection operations, thereby improving input efficiency without significantly increasing the perceived complexity for the user.

AI summary
Methods and apparatuses are provided for improving word prediction candidate selection in an electronic device. Input of one or more characters is received via a capacitive physical keyboard. A word prediction process generates a set of word prediction candidates, determines a unique character in each word prediction candidate, and displays the word prediction candidates along with visual indicia to indicate the unique character. A second input is then received comprising a tap input of a single character on the keyboard. The electronic device determines whether the second input corresponds to a unique character associated with any of the word prediction candidates, and if so, displays the selected word in an input field on the display.
