Image Stream Switcher for VR Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies for image streams lack the ability to seamlessly switch between multiple focal lengths and settings in real-time, leading to inefficient bandwidth usage and suboptimal viewer experience, especially in virtual and augmented reality applications.
Innovation Solution
Implementing light field camera technology to record multiple simultaneous image streams with varying focal lengths, apertures, and settings, which can be interlaced and switched based on user gaze direction and input, using eye-tracking and sensor inputs to adjust focus and settings dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image streams with different focal lengths are recorded simultaneously using light field camera technology, then the viewer experience is enhanced and bandwidth consumption is reduced, but the device complexity increases
Solution Approach 1:
The image data is segmented into multiple distinct image streams, each corresponding to a different focal length setting. This segmentation allows the system to process and transmit only the relevant focal length data needed for specific viewing scenarios, enhancing adaptability while managing complexity through organized data separation.
Solution Approach 2:
The light field camera system is designed to capture multiple focal length settings simultaneously, making it multi-functional. This universal capability allows a single device to serve multiple viewing needs (different focal lengths) without requiring separate recording systems, thereby improving viewer experience while controlling overall device complexity.
2Speed
If multiple simultaneous image streams are transmitted and processed, then real-time switching between focal lengths is enabled, but the bandwidth consumption increases
Solution Approach 1:
Instead of transmitting all possible focal length data continuously, the system transmits only the partial set of image streams that are currently needed based on viewer interaction. This partial action approach enables real-time switching capability while optimizing bandwidth consumption by avoiding transmission of unnecessary data.
Solution Approach 2:
The system employs periodic updates of image streams based on viewer gaze detection and interaction patterns. Rather than continuous transmission of all focal length data, the system periodically updates only the relevant streams needed for current viewing conditions, enabling real-time responsiveness while reducing overall bandwidth consumption.
3Ease of operation
If eye-tracking and sensor inputs are used to dynamically adjust focus settings, then the viewer experience is enhanced, but the device complexity increases
Solution Approach 1:
The system uses eye-tracking sensors and automated algorithms to self-adjust the focal length settings based on viewer behavior, eliminating the need for manual intervention. This self-service approach enhances ease of operation by providing automatic focus adjustment, while the complexity of sensor integration is managed through automated processing rather than manual control interfaces.

AI summary
The system for image stream switching may include a processor, a display, and a storage. The system storage includes instructions that when executed on the processor, cause the processor to provide, to the display, a first image stream from a data comprising multiple simultaneous image streams comprising the first image stream and a second image stream, the first image stream comprising a first setting, the second image stream comprising a second setting distinct from the first setting. The example system includes a storage with instructions that when executed detect a signal to switch from the first setting to a third setting that is numerically between the first setting and the second setting. The example system includes a storage with instructions that when executed provide, to the display, a third stream generated from alternating frames from the first stream and the second stream.
