VR Display Brightness Control for Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices that provide virtual reality (VR) and augmented reality (AR) struggle to intuitively convey distance between virtual objects and real objects, as they often display all virtual objects at the same brightness, making it difficult for users to distinguish between objects based on distance.
Innovation Solution
An electronic device equipped with an illuminance sensor, camera module, and processor that measures illuminance and adjusts the brightness of virtual objects based on their distance from the user, with closer objects appearing brighter and larger, and farther objects appearing darker and smaller, thereby enhancing depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all virtual objects are displayed at the same brightness, then the display is simple and power consumption is low, but the user cannot intuitively recognize the distance between objects
Solution Approach 1:
The patent applies local quality by assigning different brightness levels to different virtual objects based on their distance from the user. Closer objects are displayed with higher brightness while farther objects are displayed with lower brightness, creating a localized brightness variation that conveys depth information without requiring all objects to be uniformly bright.
Solution Approach 2:
The patent changes the brightness parameter of virtual objects dynamically based on their distance from the user. The processor adjusts the brightness parameter individually for each virtual object, creating a parameter variation that encodes spatial depth information in the visual display.
2Loss of information
If distance information is displayed to compensate for brightness uniformity, then distance information is provided, but the display size is too small to be intuitively recognized
Solution Approach 1:
The patent uses brightness variation (a form of optical property change) to encode distance information directly in the visual appearance of virtual objects. Instead of displaying separate text or numerical distance data, the system modifies the brightness property of each object to visually represent its distance, making the information immediately perceptible.
3Ease of operation
If virtual objects are displayed without brightness variation, then the display process is simple, but the user cannot distinguish which object is close and which is far
Solution Approach 1:
The patent implements dynamic brightness control where the brightness of each virtual object is adjusted in real-time based on its distance from the user. The system continuously monitors object positions and dynamically modifies brightness parameters, creating an adaptive display that responds to changing spatial relationships.
