3D Virtual Object Selection Using Hand-Defined Depth Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation for selecting a desired object from a plurality of overlapping virtual objects in a three-dimensional space is complicated.
Innovation Solution
An information processing apparatus that includes a display control unit to place virtual objects in a three-dimensional space, a setting unit to set a selection range based on positions of a user's hands, and a selection unit to switch the state of virtual objects between selected and deselected states, allowing easy selection by designating a range in the three-dimensional space.

Engineering Contradiction Analysis
1Ease of operation
If traditional selection methods are used for overlapping virtual objects, then selection accuracy can be maintained, but operation complexity increases significantly
Solution Approach 1:
The patent introduces depth-based selection by utilizing the Z-axis dimension in three-dimensional space. Virtual objects are selected based on their depth position relative to the user, allowing easy differentiation and selection of overlapping objects without complex manual operations. The selection range is defined by depth distance from the user, automatically distinguishing between foreground and background objects.
2Productivity
If manual precise selection is required for each object, then selection accuracy is maintained, but operation time increases
Solution Approach 1:
The system pre-calculates and establishes depth-based selection ranges before the user needs to select objects. By defining the selection range based on the user's current position and depth distance, the system prepares the selection criteria in advance, enabling rapid object selection without requiring time-consuming manual adjustment of selection parameters.
Solution Approach 2:
The selection system automatically determines which objects are within the selection range by calculating their depth positions relative to the user. This self-service mechanism eliminates the need for users to manually specify selection parameters, thereby reducing operation time and increasing selection productivity.

AI summary
An information processing apparatus includes at least one memory and at least one processor which function as: a display control unit configured to perform display control of a virtual object such that the virtual object is placed in a three-dimensional space that serves as a field of view of a user; a setting unit configured to set a selection range in the three-dimensional space based on a plurality of positions differently distanced from the user, the plurality of positions being designated by using an operation body located at a position of a hand of the user; and a selection unit configured to switch a state of the virtual object between a selected state and a deselected state based on the selection range.
