Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive computer simulations face challenges in maintaining user immersion due to variations in image characteristics such as luminance and contrast, which are affected by the user's position, leading to reduced effectiveness in training sessions.
Innovation Solution
A computing platform dynamically adjusts image characteristics in real-time by determining the user's position and view angle, calibrating luminance and color properties of image zones displayed on fixed screens, using multiple projectors to enhance immersion and contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple projectors are used to display images on fixed screens, then image quality and immersion are improved, but luminance uniformity deteriorates due to overlap zones
Solution Approach 1:
The patent applies local quality by differentiating treatment of display zones: blend zones receive adjusted luminance values compared to non-blend zones. The system calculates specific luminance values for each zone based on whether it falls in an overlap region between projectors, applying local compensation to achieve global uniformity.
Solution Approach 2:
The system dynamically changes luminance parameters based on user position and view angle. By adjusting the luminance of specific zones according to the user's dynamic position, the system compensates for the non-uniformity introduced by multiple projectors while maintaining overall image quality.
2Productivity
If the simulation station size is reduced, then density and energy efficiency are improved, but user immersion deteriorates due to fixed display screens
Solution Approach 1:
The patent introduces dynamics by making the display system adaptive to user movement. Instead of fixed luminance settings, the system continuously adjusts zone luminance based on real-time user position detection, allowing compact fixed screens to maintain immersion quality equivalent to larger installations.
Solution Approach 2:
The system changes display parameters (luminance values) dynamically based on user position. This allows the fixed display screens in a compact station to adapt their output characteristics, maintaining image quality and user immersion despite the reduced physical size of the simulation station.
3Illumination intensity
If luminance is adjusted for dynamic user position, then image contrast is improved, but system complexity increases
Solution Approach 1:
The patent segments the display into multiple zones (blend zones and non-blend zones) that can be independently controlled. This segmentation allows targeted luminance adjustment in specific regions without requiring complete system redesign, managing complexity through modular zone-based control.
Solution Approach 2:
The system implements feedback by detecting user position and using this information to adjust luminance settings. The continuous monitoring of user position and dynamic adjustment of zone luminance creates a closed-loop system that maintains optimal image contrast while adapting to user movement.

AI summary
A method and display system for dynamically adjusting image characteristics in real-time for a user therein. In real-time, a determination is made of a dynamic user position facing one or more fixed display screens. In real-time, and taking into account the dynamic user position, luminance of a plurality of zones is adjusted in a stream of images computed for display on the one or more fixed display screens. The calibrated (or adjusted) stream of images is then displayed onto the one or more fixed display screens. A relative view angle between the dynamic user position and the one or more fixed display screens may be determined taking into account in real-time while adjusting luminance. Adjusting in real-time, taking into account the dynamic user position, may also be performed on color properties of the plurality of zones in the stream of images.
