Virtual Object Gesture Marking in VR Line of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to navigate and interact with complex virtual reality landscapes due to confusion between virtual objects and their associated gestures in existing VR systems, which often require substantial training and can be cumbersome.
Innovation Solution
A VR device and method that provides a graphical marking of virtual objects in the user's Line Of View, indicating the associated gestures, with optional see-through views and real-time feedback to facilitate user perception and reduce confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion sensors (accelerometer and/or gyroscope) are used for determining head movements and tracking user's view in virtual reality, then the system can track user's line of view, but users find it difficult to select and execute correct functions and are often confused when navigating complex virtual reality landscapes
Solution Approach 1:
The patent introduces an intermediary visual indicator that mediates between the virtual object and the user's gesture. This indicator appears near the virtual object and provides visual feedback about the recognized gesture, helping users understand the system's interpretation of their input and reducing confusion in complex VR environments.
Solution Approach 2:
The system implements visual feedback by displaying an indicator that shows the recognized gesture near the virtual object. This feedback loop allows users to verify that their gesture was correctly interpreted and to understand which function will be executed, improving ease of operation in complex VR landscapes.
2Adaptability or versatility
If multiple virtual objects with different functions and gestures are provided in virtual reality, then the system functionality is enhanced, but users are often confused and find it difficult to handle such systems without substantial training
Solution Approach 1:
The patent applies local quality by providing gesture-specific visual indicators at the location of each virtual object. Each indicator is tailored to show the specific gesture required for that particular object, allowing users to understand the interaction requirements locally at each object rather than having to remember global gesture mappings.
Solution Approach 2:
The visual indicator acts as an intermediary that bridges the gap between the diverse virtual objects and the user's gestures. It provides context-specific information about which gesture to use for each object, reducing the cognitive load required to handle multiple functions with different gestures.
3Ease of operation
If graphical markings with gesture indications are provided for virtual objects in Line Of View, then user perception is facilitated and commands can be given swiftly and accurately, but display space is consumed
Solution Approach 1:
The system applies partial action by only displaying gesture indicators for virtual objects that are currently in the user's line of view or near the center of attention. This selective display provides necessary information to improve input speed while minimizing the display space consumed by gesture indicators.
Solution Approach 2:
The gesture indicators are displayed in a spatial dimension near the virtual objects in three-dimensional space, rather than requiring additional two-dimensional screen real estate. This allows the information to be presented without significantly increasing the perceived display area occupation.
