Gesture Interaction Undo Redo Interface Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In three-dimensional virtual environments, users face confusion when their gestures intended for interacting with virtual objects are misrecognized, leading to unintended activation of undo or redo interfaces, which are essential for improving user interaction convenience but require clear distinction from object manipulation gestures.
Innovation Solution
A method and device that activate specific undo or redo interfaces in response to unique gestures not corresponding to the primary interaction gestures, such as wrist touches or foot movements, to differentiate between object manipulation and interface control, thereby preventing confusion and enhancing interaction control in virtual spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user's gesture is used for both interacting with virtual objects and activating undo/redo interfaces, then the interaction convenience is improved, but the gesture misrecognition causes confusion between object manipulation and interface control
Solution Approach 1:
The patent divides gesture recognition into separate categories: manipulation gestures for interacting with virtual objects and control gestures for activating undo/redo interfaces. This segmentation allows the system to distinguish between different types of user intentions, reducing misrecognition while maintaining ease of operation through dedicated gesture sets for each function.
2Device complexity
If a single gesture set is used for both object manipulation and interface control, then the device complexity is reduced, but the difficulty of detecting and measuring gesture intent increases
Solution Approach 1:
The gesture system is segmented into distinct manipulation gestures and control gestures. This segmentation simplifies the detection process by creating clear boundaries between different gesture types, making it easier for the system to accurately detect and measure gesture intent without requiring complex disambiguation algorithms.
Solution Approach 2:
The patent introduces an intermediary classification layer that receives raw gesture data and determines whether the gesture belongs to the manipulation category or the control category. This intermediary step facilitates easier detection by translating complex gesture patterns into clear categorical decisions before executing the corresponding function.
3Productivity
If undo/redo interface activation is integrated with object interaction gestures, then the interaction efficiency is improved, but the loss of information about user intent occurs due to misrecognition
Solution Approach 1:
By segmenting gestures into manipulation and control categories, the system preserves user intent information more effectively. Each gesture category maintains its distinct characteristics, preventing misrecognition that would otherwise cause loss of intent information. This segmentation enables efficient undo/redo operations while accurately capturing whether the user intended to manipulate an object or control the interface.

AI summary
Provided is a method for controlling an interaction undo/redo interface. The method for controlling an interaction undo/redo interface includes causing interaction to be performed between a plurality of virtual objects created in a three-dimensional virtual space and a user, wherein the interaction is performed by recognition of the user's gesture, and activating the interaction undo interface or the interaction redo interface in response to a gesture not corresponding to the user's interaction gesture.
