Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HMDs face usability issues in arranging and displaying virtual objects, requiring laborious operations and limiting the number of visible objects due to coordinate system limitations, making it difficult to efficiently manage large numbers of virtual objects in real space.
Innovation Solution
A head-mounted display apparatus that uses a grid system with designated points for arranging virtual objects, allowing users to easily place objects at specific positions through intuitive operations such as voice, gesture, or tool-based commands, utilizing a combination of coordinate systems to enhance usability and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional coordinate system methods are used to arrange virtual objects, then the arrangement operation can be performed, but the user operation becomes laborious and the number of arrangeable objects is limited
Solution Approach 1:
The display surface is divided into multiple regions, and virtual objects are arranged in different regions rather than mixing them together. This segmentation allows users to easily locate and manage multiple objects without confusion, improving ease of operation while reducing operational complexity.
Solution Approach 2:
The patent introduces a regional dimension to the arrangement system by dividing the display surface into multiple regions. This additional spatial organization layer helps users manage more virtual objects systematically, enhancing ease of operation without significantly increasing operational complexity.
2Quantity of substance
If multiple virtual objects are arranged in the display surface, then the quantity of objects increases, but it becomes difficult to see and work with them
Solution Approach 1:
By dividing the display surface into multiple regions and distributing virtual objects across these regions, the system can accommodate a larger quantity of objects while maintaining their visibility and workability. Each region can be managed independently, reducing visual clutter and improving object detectability.
Solution Approach 2:
Different regions of the display surface can be optimized for different purposes or object types, allowing users to easily locate and work with specific objects based on their regional characteristics. This local organization improves both visibility and workability of multiple objects.
3Device complexity
If conventional arrangement methods are used, then the operation process is complex, but the system can handle basic object placement
Solution Approach 1:
The segmented regional approach simplifies the operation process by providing clear spatial boundaries and organization. Users can easily place and locate objects in specific regions without complex coordination, reducing both operational complexity and user effort simultaneously.
Solution Approach 2:
By adding the regional dimension to object arrangement, the system provides an intuitive organizational structure that reduces operational complexity. Users can leverage the regional framework to efficiently manage objects with minimal effort.

AI summary
Provided is a technique in which, in arranging a virtual object with respect to a real space, a user has less trouble, usability is good, and the object is suitably placeable. A head mounted display apparatus (HMD apparatus) according to one embodiment has a function of arranging and displaying the virtual object in a space based on an operation by a user. The HMD apparatus displays, on a display surface, a grid including a plurality of points for supporting an operation of the virtual object, and disposes and displays, according to an operation includes designation of a target virtual object and designation of a first point at an arrangement destination, the target virtual object at the position of the first point.
