Stereoscopic Display Depth Adaptation for Convergence Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic display devices impose a burden on users due to differences between the adjustment distance and convergence distance, leading to uncomfortable feelings and potential motion sickness, as they often fail to maintain the recommended convergence angle range of ±1 degree.
Innovation Solution
An information processing apparatus that determines the display format based on the convergence distance, switching between monocular and binocular displays. When the stereoscopic image is outside a predetermined range, it displays only one eye's image, reducing user burden by adjusting the display format to match the user's viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stereoscopic image is displayed with both left-eye and right-eye images to provide binocular disparity, then the stereoscopic vision experience is improved, but the convergence angle difference between adjustment distance and convergence distance increases, imposing a burden on the user
Solution Approach 1:
The display device dynamically switches between binocular display mode (displaying both left-eye and right-eye images) and monocular display mode (displaying only one eye's image) based on the depth position of the virtual image. When the virtual image is within a predetermined depth range, binocular display is used to provide stereoscopic vision. When the virtual image is outside this range, monocular display is used to reduce the convergence angle difference and minimize user burden, creating a dynamic adaptation system.
Solution Approach 2:
The system changes the display parameter (number of images displayed) based on the depth position parameter of the virtual image. By monitoring whether the virtual image depth is within the predetermined range and adjusting the display mode accordingly, the system optimizes the balance between stereoscopic vision quality and user comfort by controlling the convergence angle difference.
2Adaptability or versatility
If the virtual image is displayed at a depth position outside the predetermined range, then the convergence angle difference increases causing user discomfort, but maintaining binocular display preserves the stereoscopic effect
Solution Approach 1:
The display mode is dynamically adjusted based on virtual image depth position. The system automatically transitions between binocular and monocular display modes according to whether the virtual image is within or outside the predetermined depth range, optimizing both stereoscopic effect and user comfort in real-time.
Solution Approach 2:
Different display qualities are applied to different depth regions. Within the predetermined depth range, full binocular display provides high-quality stereoscopic effect. Outside this range, monocular display is used to prioritize user comfort, creating localized quality optimization based on spatial position.
3Object-affected harmful factors
If only one eye's image is displayed to reduce convergence angle difference, then user burden is reduced, but binocular disparity and stereoscopic vision are lost
Solution Approach 1:
The system dynamically switches between monocular and binocular display modes based on virtual image depth. When the virtual image is outside the predetermined range, monocular display reduces user burden. When within the range, binocular display restores stereoscopic vision, creating a dynamic balance between comfort and visual effect.
Solution Approach 2:
The display mode alternates between monocular and binocular modes based on the depth position of virtual images. As virtual images move in and out of the predetermined depth range, the system periodically switches display modes to maintain optimal user experience throughout the viewing session.

AI summary
[Problem] To provide an information processing apparatus, an information processing method, and a program. [Solution] An information processing apparatus including a display control unit that causes a display unit to display a virtual image in a three-dimensional space. The display control unit causes the display unit to display only one of a left-eye image and a right-eye image corresponding to the virtual image if it is determined that the virtual image is located outside of a predetermined range in a depth direction when viewed from a user of the display unit, and causes the display unit to display the left-eye image and the right-eye image if it is determined that the virtual image is located inside of the predetermined range.
