VR Boundary Setting with Multi-Height Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR technologies cannot effectively set boundary surfaces with varying heights, leading to a reduction in the permissible region to avoid real-space objects, resulting in a less immersive user experience.
Innovation Solution
A boundary setting device and method that allows for the flexible setting of boundary surfaces with multiple height levels, using first and second boundary lines, parallel shifting, and sensor trajectory-based settings, enabling the user to define permissible and impermissible regions dynamically.

1Reliability
If a boundary surface is set to include the whole region extending in height direction to avoid real-space objects, then collision prevention is improved, but the permissible region becomes smaller
Solution Approach 1:
The boundary surface is segmented into multiple boundary lines at different heights (first boundary line at first height, second boundary line at second height). This segmentation allows the system to create a more precise boundary that follows the actual shape of real-space objects, preventing collisions while minimizing the reduction of the permissible region.
Solution Approach 2:
Different portions of the boundary surface are assigned different heights based on the local requirements for collision prevention. The first boundary line and second boundary line are positioned at different heights to match the specific geometry of objects in different locations, allowing the permissible region to be maximized while still preventing collisions where needed.
2Volume of moving object
If a boundary surface with varying heights is set, then the permissible region is maximized, but the device complexity increases
Solution Approach 1:
The boundary surface is made dynamic and adjustable through user input. Users can specify multiple boundary lines at different heights, and the system dynamically creates the boundary surface based on these inputs. This allows the boundary to adapt to different spatial configurations and object arrangements without requiring complex pre-programmed structures.
Solution Approach 2:
The boundary setting extends from a single-plane (2D) concept to a multi-height (3D) concept by introducing boundary lines at different heights. This dimensional expansion allows the system to accurately represent the vertical geometry of real-space objects, creating a more precise permissible region while managing complexity through structured user input methods.

AI summary
A boundary surface setting section sets the boundary surface for delimiting a permissible region that is the region which is located inside the real space and in which the user wearing a head-mounted display is permitted to exist and an impermissible region that is the region which is located inside the real space and in which the user is not permitted to exist. A display control section causes a portion or a whole of a virtual object representing the boundary surface to be displayed on the head-mounted display. The boundary surface includes a first boundary line having a first height and a second boundary line having a second height, and a portion or all of the first boundary line is different from the second boundary line.
