VR Screen IPD Configuration via Dynamic Object Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality (VR) services often fail to provide realistic experiences due to the lack of consideration for individual users' interpupillary distances (IPD), resulting in inconsistent image presentation across different users.
Innovation Solution
A method and apparatus for configuring electronic device screens to determine and adjust the IPD by displaying objects corresponding to each eye, allowing users to input threshold distances to optimize image alignment and size, thereby providing personalized VR experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed IPD is used for all users in VR services, then the device complexity is reduced and ease of operation is improved, but the adaptability to individual users deteriorates and manufacturing precision of the VR experience worsens
Solution Approach 1:
The patent implements dynamic IPD adjustment by allowing users to input their specific interpupillary distance values, transforming the static display configuration into a dynamic one that adapts to individual users. The system adjusts the distance between virtual objects based on user input, enabling the VR experience to be customized for each user while maintaining ease of operation through simple input mechanisms.
Solution Approach 2:
The patent changes the display parameters (object distance, image size) based on user-specific IPD values. By allowing users to input their interpupillary distance and automatically adjusting the virtual reality parameters accordingly, the system achieves both ease of operation and high adaptability to individual users.
2Device complexity
If a fixed IPD is used for all users, then the device complexity is reduced, but the manufacturing precision of the VR experience deteriorates
Solution Approach 1:
The patent modifies display parameters such as object distance and image size based on user-specific IPD values. This parameter adjustment approach maintains simple device architecture while achieving high precision in the VR experience by tailoring the display configuration to each user's anatomical characteristics.
3Manufacturing precision
If individual IPD configuration is implemented for all users, then the adaptability to users is improved and manufacturing precision is enhanced, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic configuration system where display parameters are adjusted based on user input without requiring complex hardware modifications. The system dynamically adapts object distance and image size based on individual IPD values, achieving high manufacturing precision through software-based parameter adjustment rather than complex physical configurations.
4Adaptability or versatility
If individual IPD configuration is implemented, then the adaptability to users is improved, but the device complexity increases
Solution Approach 1:
The patent achieves high user adaptability by changing display parameters (object distance, image size) based on user-specific IPD inputs. This software-based parameter adjustment approach enables individualized VR experiences without requiring complex hardware modifications or additional physical components.

AI summary
Methods and apparatuses are provided for configuring a screen of an electronic device. A first object, corresponding to a left eye of a user of the electronic device, and a second object, corresponding to a right eye of the user, are displayed on the screen. A threshold distance is obtained, which is one of a minimum distance and a maximum distance between the first object and the second object at which an image, corresponding to the first object and the second object, is properly viewed by the user. An interpupillary distance (IPD) is determined between the first eye and the second eye based on the threshold distance.
