Head-Mounted Display Angle of View Switching for Focused Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies for head-mounted displays fail to efficiently adapt the angle of view based on user orientation, leading to suboptimal viewing experiences as users struggle to focus on specific regions within wide-angle images.
Innovation Solution
An image processing device and method that acquires orientation information from a head portion, switches the angle of view based on user input or automatically, and renders images to track head movement, allowing users to switch between narrow and wide angles for focused or general viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a wide-angle image is displayed to provide full space viewing, then the field of view is improved, but the user cannot focus on specific regions
Solution Approach 1:
The patent implements dynamic angle of view adjustment where the display transitions between wide-angle and narrow-angle views based on user interaction. The rendering process unit dynamically changes the angle of view parameter, allowing the system to adapt between providing full space overview and enabling focused observation of specific regions within the virtual environment.
2Adaptability or versatility
If head movement tracking is implemented to follow user orientation, then the viewing experience is improved, but the system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the orientation detection device continuously monitors head portion orientation and feeds this information back to the rendering process unit. This feedback loop enables the display to automatically adjust and track user movements, creating an adaptive viewing experience that responds to user actions in real-time.
3Ease of operation
If angle of view switching is added to allow focused viewing, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service functionality where the system automatically switches between wide-angle and narrow-angle views based on detected user actions such as head movements or input operations. The angle of view switching occurs without requiring separate control mechanisms or additional user interface elements, as the rendering process unit autonomously adjusts parameters based on orientation data and user interactions.

AI summary
An image processing device includes an orientation information acquisition unit which acquires orientation information of a head portion of a user that observes a display image of a display device; an angle of view switching unit which switches an angle of view of the display image; a rendering process unit which generates the display image based on the orientation information and the angle of view; and a transmission unit which transmits the generated image to the display device.
