Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Amusement parks face challenges in creating immersive visual experiences due to the high cost, complexity, and equipment availability of using virtual, augmented, and mixed reality technologies for displaying media content, particularly with head-mounted displays.
Innovation Solution
A light display system that utilizes a light source emitting multiple frames of an image as light patterns, coordinated with a control system and a rotating reflective surface to create a persistence of vision effect, allowing users to visualize the image without the need for expensive or complex head-mounted displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If virtual reality, augmented reality, or mixed reality headsets are used to display media content, then immersive visual experience is improved, but cost and device complexity increase
Solution Approach 1:
The patent creates an optical copy of the image sequence using a rotating reflective surface (mirror) that reflects light from a light source to form images in the air. Instead of requiring users to wear complex head-mounted displays, the system projects optical copies of the image sequence that can be viewed directly, thereby achieving immersive visual experience while eliminating the need for expensive VR/AR headset equipment
Solution Approach 2:
The patent replaces the mechanical/electronic system of head-mounted displays with an optical system using light sources and rotating reflective surfaces. The control system electronically generates image sequences, but the display mechanism uses optical reflection and persistence of vision rather than complex mechanical headsets, thereby reducing device complexity while maintaining visual experience quality
2Illumination intensity
If virtual reality, augmented reality, or mixed reality headsets are used to display media content, then immersive visual experience is improved, but equipment cost increases
Solution Approach 1:
The system creates optical copies of images using simple reflective surfaces and light sources rather than expensive head-mounted displays. The rotating mirror reflects light from a relatively simple light source to create visible image sequences in the air, providing immersive experience without requiring costly VR/AR headset manufacturing
Solution Approach 2:
The patent uses relatively simple and inexpensive components: a light source, a rotating reflective surface, and a control system. These components are much cheaper than VR/AR headsets while achieving the same immersive visual effect. The system sacrifices the reusability and adjustability of headsets for the advantage of lower cost and simpler manufacturing
3Productivity
If a light source emits multiple light patterns sequentially and a reflective surface rotates at coordinated rates, then persistence of vision effect is achieved, but device complexity increases
Solution Approach 1:
The patent combines the light source, rotating reflective surface, and control system into an integrated display apparatus. The control system coordinates the light patterns and rotation rate to create the persistence of vision effect, merging multiple functions into a single cohesive system that achieves image display capability without requiring separate complex subsystems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides an immersive and cost-effective way to display media content by using a light source and rotating reflective surfaces to create the illusion of moving images, reducing the reliance on expensive VR/AR equipment and enhancing entertainment experiences in amusement parks.
Implementation Method 1
a reflective surface configured to rotate relative to the light source to thereby display the image for visualization by a user
Implementation Method 2
The light source is configured to sequentially emit the plurality of light patterns based on instructions from a control system such that the multiple frames are presented in a sequence
Data Source
AI summary
A light display system may display an image to a user and/or an audience using a persistence of vision effect. In an embodiment, a light display system includes a light source configured to emit a plurality of light patterns that correspond to multiple frames of an image. The light source is configured to sequentially emit the plurality of light patterns based on instructions from a control system such that the multiple frames are presented in a sequence at a first rate. The light display system also includes an image expander configured to reflect the plurality of light patterns toward a user of the head-mounted device, wherein at least a portion of the image expander is configured to rotate relative to the light source at a second rate that is coordinated with the first rate by the control system to thereby display the image for visualization by the user.
