In-context word prediction using on-screen candidate display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing predictive text input methods for electronic devices require users to divert attention from the keyboard to view and consider suggested words, leading to eye strain, inefficiency, and wasted processing cycles, as they often only provide predictions for the current word being entered and lack contextual understanding.
Innovation Solution
A method that allows users to input text without diverting attention from the keyboard by displaying candidate predictions on the touchscreen, enabling continuous touch input to accept predictions, and using a timer based on touch distance from the screen edge to confirm selections, thus allowing simultaneous selection and confirmation of multiple words.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If predictive text input methods display suggested words on the touchscreen, then text input speed is improved, but users must divert attention from the keyboard causing eye strain and inefficiency
Solution Approach 1:
The patent applies dimensionality change by moving the prediction display from a separate visual location (touchscreen) to the same spatial plane as the keyboard input. Predictions are displayed directly on the keyboard interface, allowing users to select predicted characters without shifting their gaze or attention between different display areas. This resolves the contradiction by maintaining high input speed while eliminating the need for diverted attention.
2Loss of energy
If the system provides predictions for only the current word, then processing cycles are optimized, but contextual understanding and prediction accuracy are limited
Solution Approach 1:
The system applies preliminary action by pre-calculating and preparing multiple levels of predictions (current word completions and subsequent word predictions) before the user actually needs them. This allows the system to provide accurate contextual predictions for multiple words ahead of time without wasting processing cycles on unnecessary calculations, as predictions are generated only for relevant contextual positions based on current input state.
3Measurement precision
If users must view and consider suggested words on the touchscreen, then prediction accuracy can be evaluated, but text input efficiency decreases due to attention diversion
Solution Approach 1:
The patent merges the prediction display function with the keyboard input interface by integrating suggested characters directly into the keyboard layout. Users can evaluate and select predictions within the same visual field as their typing activity, eliminating the need to switch attention between keyboard and separate display areas. This combining approach maintains prediction evaluation capability while preserving text input efficiency.

AI summary
Methods and systems for predicting user input on a keyboard. Methods include enabling user input on a display comprising at least three fields. The first field displays an input string that is based on input selections such as keyboard entries. The second field displays a candidate prediction generated based on other input selections, consisting at least in part of a proposed completion to the input selection, and partially based on the input string in the first field. The third field displays another candidate prediction generated based on the input string in the first field as well as the candidate prediction in the second field.
