Touchscreen Object Duplication via Interaction Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for duplicating objects on touch-sensitive displays are time-consuming, non-intuitive, and lack precision due to the need for cumbersome gestures and menu interactions, which are not ergonomically natural for users.
Innovation Solution
A computer-implemented method that detects a first user interaction and a second user interaction on a selected object, allowing the duplicated object to track the movement of the first interaction and be positioned at the last detected location on the touch-sensitive display, eliminating the need for supplementary interactions and menu calls, enabling intuitive and precise duplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional menu-based copy/paste operations are used on touch-sensitive displays, then duplication functionality is achieved, but the operation becomes time-consuming and non-intuitive
Solution Approach 1:
The patent applies the copying principle by detecting a user interaction (such as a tap or click) on a selected object and automatically generating a duplicate instance of that object. The system copies the object's properties and creates a new instance without requiring traditional menu navigation, thereby making the operation intuitive and time-efficient.
Solution Approach 2:
The system implements self-service by automatically handling the duplication process once a user interaction is detected. The computer system itself performs the copy and placement operations without requiring the user to manually invoke menus or commands, thus eliminating unnecessary interaction steps and reducing operation time.
2Measurement precision
If multiple user interactions are required for precise duplication, then positioning accuracy improves, but the complexity of the operation increases
Solution Approach 1:
The patent segments the duplication operation into distinct phases: selection phase (detecting first user interaction on selected object), duplication phase (detecting second user interaction to create duplicate), and positioning phase (tracking movement to determine final placement). This segmentation allows precise control over each aspect of the operation while keeping the overall process manageable and not overly complex.
3Measurement precision
If the duplicated object tracks movement continuously, then positioning precision is improved, but processing requirements increase
Solution Approach 1:
The system applies partial action by tracking and updating the duplicated object's position only during the critical phase when the user is actively moving the selection, rather than continuously updating throughout the entire interaction sequence. This reduces processing energy while maintaining sufficient positioning precision for the duplication operation.

AI summary
The invention is directed to a computer-implemented method for duplicating an object using a touch-sensitive display. The method comprises: - displaying (10) a selected first object (12) on the touch-sensitive display; - detecting a first user interaction and a second user interaction (14) on the selected first object; - detecting a movement (16) of the first user interaction outside the selected first object; - displaying a second object (20) which tracks the movement of the first user interaction on the touch-sensitive display, the second object being a duplication of the first object; and - positioning the second object (26) according to a last detected location of the first user interaction on the touch-sensitive display.
