Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted information processing apparatuses have limitations in visual field range, leading to difficulties in visually recognizing virtual objects placed behind real objects or out of the visual field in augmented reality spaces.
Innovation Solution
A head-mounted information processing apparatus equipped with a virtual object generation processor, input operation unit, camera, and controller, which generates and displays virtual objects within a display visual field, allowing for batch display and attitude operations to enhance visibility, including full spherical image projection and semi-transparent display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the visual field is expanded in the virtual space, then the display range is widened, but the virtual object placed behind a real object or out of the visual field cannot be visually recognized
Solution Approach 1:
The patent introduces a batch display mode that projects virtual objects onto a spherical surface representing the entire visual field, adding a dimensional transformation from traditional 2D display to 3D spherical projection. This allows users to perceive the spatial arrangement of multiple virtual objects simultaneously across different depth planes, solving the recognition problem without expanding the physical display area.
Solution Approach 2:
The patent creates a virtual copy of the real-world environment by capturing images with a camera and overlaying virtual objects onto the captured real-space images. This copying approach allows virtual objects to be displayed in their correct spatial positions relative to real objects, enabling users to recognize virtual objects even when they would traditionally be hidden behind real objects in the physical world.
2Reliability
If virtual objects are displayed in their correct spatial positions, then the authenticity of augmented reality is improved, but virtual objects behind real objects become invisible
Solution Approach 1:
The patent segments the display into multiple modes: a normal display mode for single-object interaction and a batch display mode for multi-object overview. In batch display mode, the spherical projection divides the visual field into different regions corresponding to different spatial depths, allowing users to segment their attention across multiple virtual objects at different positions simultaneously, including those behind real objects.
Solution Approach 2:
The patent performs preliminary action by capturing real-world images in advance and preparing batch display data that includes spatial information about virtual objects before the user needs to view them. The system pre-calculates the spherical projection coordinates and prepares the overlay images, so when the user activates batch display mode, the information is immediately available without requiring real-time processing, enabling quick recognition of virtual object positions.

AI summary
The existence position of the virtual object displayed by the virtual reality or augmented reality is easily grasped. In a head-mounted information processing apparatus, a virtual object generation processor generates a virtual object. An input operation unit sets and inputs information. A camera captures a real space. A display unit displays a photographed image captured by the camera and the virtual object generated by the virtual object generation processor. The controller controls the virtual object generation processor and the display unit. The controller displays the virtual objects generated by the virtual object generation processor in a batch within a display visual field screen of the display unit in accordance with virtual object display instruction information for instructing display of the virtual object input from the input operation unit.
