Naked-Eye 3D Display Interaction With Spatial Reference Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in 3D interactive scenes face challenges in accurately perceiving the spatial relationship between themselves and 3D objects due to differences in depth perception, leading to suboptimal interactive experiences.
Innovation Solution
A display method that includes capturing interactive operations using image acquisition devices, analyzing operation parameters, and displaying secondary objects based on position information to guide users in accurately interacting with primary objects, utilizing virtual light sources, hands, or cursor areas to enhance perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with 3D objects directly in a naked-eye 3D scene, then the interaction simplicity is improved, but the spatial perception accuracy deteriorates due to differences in depth perception among users
Solution Approach 1:
The patent introduces a second object as an intermediary between the user and the first object. This second object serves as a visual reference that mediates the interaction by providing clear spatial and positional information about the first object, thereby resolving the contradiction between simple direct interaction and accurate spatial perception.
Solution Approach 2:
The system provides real-time feedback by displaying the second object that reflects the user's interaction state and position relative to the first object. This feedback loop enables users to adjust their interactions based on visual cues, improving spatial perception accuracy without complicating the interaction process.
2Measurement precision
If visual cues are added to improve spatial perception, then the interaction accuracy is improved, but the display system complexity increases
Solution Approach 1:
The patent creates a simplified visual copy (the second object) that represents key spatial information about the first object. This copy provides necessary visual cues for accurate interaction without requiring complex modifications to the display system or the original 3D scene.

AI summary
A display method includes obtaining an interactive operation and an operation parameter for a first object displayed in a naked-eye 3D state. The operation parameter characterizes the interactive operation. The method further includes displaying a second object in response to the operation parameter satisfying a target condition, obtaining position information related to the first object in response to the interactive operation, and controlling a display state of the second object based on the position information.
