Touchscreen Content Movement via Hand Shape Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch screens present an unfamiliar interface for users when moving content, particularly for those new to touch screen technology, as they require specific gestures like dragging to move content, which can be confusing.
Innovation Solution
A method and apparatus that detect at least two touches, recognize a combined shape of these touches, such as a user's fingers or stylus, and move content based on the change from a grabbing to an open-hand shape, allowing intuitive content movement similar to lifting and placing objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional touch screen interface is used for moving content, then the device can perform content movement function, but the interface is unfamiliar and confusing for new users
Solution Approach 1:
The patent copies real-world physical gestures (grabbing with fingers, opening hand to release) and translates them into touch screen operations. The system detects finger patterns that resemble grabbing gestures and maps them to content selection and movement operations, making the interface more intuitive for users familiar with physical object manipulation
Solution Approach 2:
The patent replaces traditional mechanical touch screen interaction (dragging with one finger) with a gesture-based system that uses multiple touch points to simulate hand movements. The camera captures finger positions and translates them into virtual grabbing and releasing actions, substituting direct mechanical contact with optical detection and gesture interpretation
2Ease of operation
If multiple touches are detected to recognize hand shape, then the content movement becomes more intuitive, but the detection and measurement complexity increases
Solution Approach 1:
The system pre-defines specific touch patterns that correspond to grabbing gestures (such as two fingers positioned at specific distances and angles). By establishing these patterns in advance, the system can quickly match detected touches against known gestures without performing complex real-time analysis, reducing detection complexity while maintaining gesture recognition accuracy
Solution Approach 2:
The patent changes the detection parameters from analyzing continuous finger movement trajectories to detecting static touch point positions and relationships. By focusing on positional parameters (distance between touches, angular relationships) rather than motion parameters, the system simplifies the detection process while still capturing the essential characteristics of grabbing gestures

AI summary
A method for moving content and an electronic device thereof is provided. The method includes detecting at least two touches, selecting content corresponding to locations at which the at least two touches are detected, detecting a combined shape of touch entities corresponding to the at least two touches if the detected at least two touches are released, and moving the selected content to a location at which the combined shape of the detected at least two touch entities is changed, wherein the touch entities include at least one of a user's finger, a stylus pen, and an extra touch tool.
