Touch-Sensitive Display Hover Preview and Tactile Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in providing efficient input methods due to the small size of the devices and the need for improved user interaction, particularly in previewing and selecting options without covering the entire option with the contact member.
Innovation Solution
The implementation of a method and apparatus that allows previewing of selection options on a touch-sensitive display by displaying them in alternative formats when a hovering touch is detected, providing tactile feedback, and enabling selection through depression of the display or actuation of actuators, such as mechanical or piezo actuators, to facilitate accurate and efficient input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the touch-sensitive display size is decreased to improve portability, then the device becomes more portable, but the input efficiency and user interaction quality deteriorate
Solution Approach 1:
The system performs preliminary action by displaying a preview of the selected option at the cursor position before the user completes the selection. This allows users to verify the selected character or option immediately without lifting their finger, enabling continuous input flow and maintaining high input efficiency even on small displays.
Solution Approach 2:
The preview display acts as an intermediary between the selection action and the final input confirmation. It provides visual feedback about the selected option without requiring the user's finger to cover the entire option, thus maintaining input efficiency on small displays through intermediate visual confirmation.
2Measurement precision
If the user covers the entire selection option with their contact member to ensure accurate selection, then selection accuracy improves, but the preview of the option becomes obscured and input speed decreases
Solution Approach 1:
The system resolves the contradiction by moving the preview display to a different spatial dimension - specifically, displaying the preview at the cursor position in the text field rather than requiring the user to view the full option under their finger. This dimensional relocation allows simultaneous accurate selection and visible preview.
Solution Approach 2:
The preview at the cursor position serves as an intermediary that provides selection confirmation without requiring the user to lift their finger or cover the option. This intermediary display maintains both selection accuracy and input speed by providing visual feedback in a different location.
3Loss of information
If the display shows the full selection option for clear visibility, then user understanding improves, but the contact member must cover more area reducing typing speed
Solution Approach 1:
The system segments the information display into two parts: the full selection option remains visible for information completeness, while a condensed preview is displayed at the cursor position for quick verification. This segmentation allows users to access full information when needed while maintaining fast input flow through the compact preview.
Solution Approach 2:
The system applies partial action by displaying only the essential preview information at the cursor position rather than requiring the full option to be visible. This partial display provides sufficient information for verification while minimizing the area covered by the contact member, thus maintaining typing speed.

Function Achieved in This Case
This solution enhances user interaction by providing clear previews of selection options, improving typing accuracy and speed on touch-sensitive displays by allowing users to preview options without fully covering them, thus reducing errors and improving overall input efficiency.

AI summary
A method includes displaying one or more selection options on a touch-sensitive display and detecting a hovering touch associated with a first option of the one or more selection options. Information associated with the first option is previewed in a first format in an information field in response to detecting the hovering touch. A selection of one of the one or more selection options is detected, and a function associated with the selected option is performed.
