Static Touch Input Duration for Selection Area Definition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accurately and efficiently selecting items or parts of items on electronic devices using touch user inputs, as existing methods lack precision and ease in defining selection areas, especially when using touch or hover gestures.
Innovation Solution
An apparatus and method that detect static touch user inputs to define a start point for a selection area, with the area's size and direction determined by the duration of the static input, allowing for fine-tuning through rocking gestures, enabling accurate selection of text, images, or cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional touch input methods are used for selection, then the operation is simple, but the selection precision is poor
Solution Approach 1:
The patent transforms a static touch selection into a dynamic process where the selection area expands over time. The user performs a static touch input that remains on the screen for a duration, and during this time the selection area dynamically expands from the touch point. This dynamic expansion allows precise selection control while maintaining simple user interaction.
Solution Approach 2:
The patent applies preliminary action by having the user perform a static touch input that defines the start point and duration before the actual selection area is fully formed. The touch duration pre-determines the selection area size, allowing the system to prepare the selection before final confirmation, thus improving precision without complicating the user action.
2Measurement precision
If selection area is defined by touch duration, then the selection accuracy is improved, but the operation time increases
Solution Approach 1:
The patent changes the parameter of touch input from position-only to position-plus-duration. By introducing duration as a controlling parameter, the system can accurately determine selection area size based on how long the user maintains the touch, rather than requiring complex gesture movements. This parameter change improves selection accuracy while keeping the user action simple and time-efficient.
3Measurement precision
If static touch input is used to define selection area, then the selection control is precise, but the user input complexity increases
Solution Approach 1:
The patent applies self-service by allowing the touch input itself to provide all necessary information for selection. The static touch's position provides the start point, and its duration provides the selection area size. The system automatically processes this simple input to create the selection area, eliminating the need for complex multi-step gestures or additional controls.
