Virtual 3D GUI Depth Range Segmentation for Intuitive Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual three-dimensional GUIs, users face difficulties in issuing operation instructions in the depth direction due to the structural limitations of the human body, making it challenging to effectively interact with objects located in peripheral regions of the virtual space.
Innovation Solution
An information processing device and method that sets distinct ranges for the depth direction of objects in a virtual three-dimensional space, with a wider range in the center region and a narrower range in the peripheral region, along with a notification system to guide users' interactions, allowing for intuitive operation in the depth direction and reducing visual burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a GUI is displayed as a virtual three-dimensional space with objects arranged in depth direction, then space utilization is improved, but operation difficulty in depth direction increases due to human body structural limitations
Solution Approach 1:
The virtual three-dimensional space is segmented into a center region and peripheral regions. Objects in the center region are arranged with a wider depth range, while objects in peripheral regions are arranged with a narrower depth range, making them easier to operate despite the overall three-dimensional layout
Solution Approach 2:
Different regions of the virtual space are assigned different depth ranges. The center region has a larger depth range for displaying objects, while peripheral regions have smaller depth ranges, creating local variations in operability that accommodate human movement limitations
2Area of stationary object
If objects are arranged with wide depth range throughout the virtual space, then space utilization is improved, but visual burden on users increases
Solution Approach 1:
The depth range of objects is varied by region: center region objects have wider depth ranges while peripheral region objects have narrower depth ranges. This local differentiation maintains effective space utilization in the center while reducing visual burden in peripheral areas where users have less control precision
3Device complexity
If uniform depth range is applied to all objects in virtual space, then system simplicity is maintained, but operability in peripheral regions deteriorates
Solution Approach 1:
The virtual space is divided into center and peripheral regions with different depth range characteristics. This segmentation allows the system to maintain relative simplicity while improving operability in peripheral regions through localized adjustments to object arrangement

AI summary
There is provided an information processing device including a display control section configured to display objects in a virtual three-dimensional space, the virtual three-dimensional space including a depth direction of a display screen and having a center region and a peripheral region located around the center region, and an acquisition section configured to acquire an operation on the objects at least in the depth direction based on a movement of a body of a user. The range of the depth direction in which the objects are displayed is set to a first range in the center region and to a second range narrower than the first range in the peripheral region.
