Display Apparatus Audio-Visual Adaptation by User Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for creating immersive natural phenomenon displays, such as waterfalls, require excessive resources and lead to user fatigue due to repetitive video reproduction and lack of realism as the user's location and distance from the display are not dynamically considered.
Innovation Solution
A display apparatus comprising a display, speakers, and a processor that adjusts sound frequencies and image effects based on the user's location, using sensors to determine the user's position and distance, and adjusts sound weights, phases, and volumes to create a more immersive experience by simulating the natural phenomenon's proximity and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repetitive video reproduction is used to manufacture contents, then the display can show natural phenomena, but user fatigue increases and sense of realism deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from static repetitive video reproduction to dynamic real-time rendering that responds to user position and interaction. The system dynamically adjusts visual and auditory outputs based on user proximity and movement, creating an adaptive experience that maintains realism without repetition fatigue.
Solution Approach 2:
The patent changes key parameters including rendering mode (from pre-recorded video to real-time simulation), response time (from fixed playback to interactive adaptation), and environmental factors (adding user position and distance sensing). These parameter changes enable the system to maintain high realism while eliminating repetitive viewing fatigue.
2Reliability
If real time rendering through fluid simulation is used, then sense of realism improves, but excessive resources are required
Solution Approach 1:
The patent applies local quality by focusing computational resources on specific regions and aspects rather than uniform full-scene rendering. The system prioritizes rendering quality in areas where users are physically present and interacts with the content, while using simplified representations elsewhere, thereby reducing overall computational resource consumption.
Solution Approach 2:
The patent uses partial action by implementing real-time rendering only for the portion of the virtual environment that is currently relevant to user interaction and position, rather than rendering the entire scene at full fidelity continuously. This selective rendering approach maintains realism where needed while conserving computational resources.
3Adaptability or versatility
If the display shows fixed content, then the system is simple to control, but adaptability to user location and distance is insufficient
Solution Approach 1:
The patent implements self-service by enabling the display system to automatically detect and respond to user position and distance without requiring manual input or configuration. The system uses sensors to autonomously adjust visual and auditory outputs based on user proximity, creating adaptability while keeping the user interface simple.
Solution Approach 2:
The patent applies feedback by incorporating sensor data about user position and distance into the content delivery system. The system continuously monitors user location and adjusts rendering parameters, audio spatialization, and interactivity based on this feedback, achieving high adaptability through a relatively simple feedback loop architecture.
