Predictive Keyboard Gesture Selection and Dynamic Suggestion Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing predictive keyboard systems on electronic devices with touch-sensitive surfaces are inefficient, requiring users to move their contact point away from the keyboard to select predicted character strings, wasting time and energy, and often distract users with changing suggestions, increasing cognitive burden and reducing typing efficiency.
Innovation Solution
A method and interface that displays suggested character strings above the on-screen keyboard, allowing users to insert characters by gestures within or outside a predefined key, updating suggestions dynamically by maintaining and modifying displayed character strings based on entered characters, and adding predicted characters, thereby streamlining the typing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user moves the contact point away from the on-screen keyboard region to tap the predicted character string region, then the predicted character string can be selected, but the user's time is wasted and the device's energy is consumed
Solution Approach 1:
The patent merges the keyboard input area with the prediction display area by showing predictions above the keyboard. Users can select predictions by tapping the same key without moving their contact point, combining selection and input actions into one location.
Solution Approach 2:
The system performs preliminary action by displaying predicted character strings before the user completes typing. This allows users to select predictions in advance without having to type the entire string, saving time and effort.
2Adaptability or versatility
If the predicted character strings are displayed and change as the user types, then prediction functionality is provided, but the user is distracted and cognitive burden increases
Solution Approach 1:
The system implements dynamics by allowing predictions to change adaptively as the user types. The predictions update based on the current input state, providing relevant suggestions while maintaining a stable display position above the keyboard to minimize distraction.
3Productivity
If the user taps the predicted character string region, then the character string is inserted, but the user must move the contact point away from the keyboard
Solution Approach 1:
The patent combines the prediction selection function with the keyboard key press action. Users select predictions by tapping the same key that would normally input a character, merging selection and input into a single action at the same location.
Solution Approach 2:
The system introduces an intermediary mechanism where the prediction display acts as a mediator between the user's intent and the text input. The predictions are displayed above the keyboard and can be selected through key presses, facilitating smooth transitions without requiring contact point movement.

AI summary
A method includes displaying a suggestion region above an on-screen keyboard. The suggestion region includes multiple suggested character strings. The method further includes: detecting a gesture that begins within a predefined key of the on-screen keyboard; and responsive to detecting the gesture: in accordance with a determination that the gesture ends within the predefined key, inserting a first character string into a text field; and in accordance with a determination that the gesture ends outside of the predefined key, inserting a second character string into the text field, wherein the second character string is different from the first character string.
