Virtual Keyboard Ticker for Predictive Text Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current predictive text input methods on electronic devices require users to divert attention from the keyboard, leading to eye strain and inefficiency, especially when composing long texts, as they need to view suggestions displayed elsewhere on the screen, causing processor idle cycles and wasted display power.
Innovation Solution
A method that displays input characters and predicted sets of characters within a ticker located proximate to the virtual keyboard, allowing users to maintain focus on the keyboard while receiving word context and error indications, with the ticker scrolling to maintain the cursor's fixed position at the center, reducing eye movement and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If predictive text suggestions are displayed elsewhere on the screen, then users can receive word context and error indications, but users must divert attention from the keyboard causing eye strain and inefficiency
Solution Approach 1:
The patent combines the predictive text display area with the keyboard area by implementing a scrolling display that shows predictive suggestions directly adjacent to the keyboard. This merging allows users to view both the keyboard and predictive text without diverting attention, as both elements occupy overlapping or adjacent spatial regions on the display.
Solution Approach 2:
The patent utilizes the temporal dimension through scrolling to resolve the spatial conflict between keyboard and predictive text display. By making the display scroll dynamically based on keyboard input, the system provides predictive suggestions in a time-varying manner that maintains spatial proximity to the keyboard, allowing users to perceive both elements within a compact area.
2Loss of information
If users view predictive suggestions displayed elsewhere on the screen, then they can receive text context, but processor idle cycles increase and display power is wasted
Solution Approach 1:
The patent implements periodic updates of the predictive text display that are synchronized with keyboard input events. The display scrolls and updates only when triggered by user input, rather than continuously refreshing. This periodic action reduces processor idle cycles and display power consumption while maintaining the provision of text context information.
Solution Approach 2:
The scrolling display maintains continuous useful action by keeping predictive suggestions visible in proximity to the keyboard throughout the typing process. The display continuously provides context information without requiring separate viewing actions, thereby eliminating processor idle cycles that would occur if the display had to refresh or redraw suggestions elsewhere on the screen.

AI summary
A method comprising receiving an input of a character from a virtual keyboard (320) rendered on a display, and displaying the input character left of a cursor (340) located within a ticker (350) rendered on the display proximate to the virtual keyboard (320), wherein the cursor (340) has a set position located towards a centre of the ticker (350).
