Theater Caption Display via Seat-Back Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing captioning systems in theaters are expensive, prone to theft or breakage, and suffer from operational limitations, with potential for signal leakage between auditoriums, and do not efficiently support multiple language displays for all audience members.
Innovation Solution
A system and method for displaying multiple captions in different colors and polarizations, allowing selective viewing through color filters and polarizers, enabling simultaneous display of multiple languages or information on a single screen without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personalized multi-language display devices are used to provide captions to audience members, then accessibility for hearing-impaired and non-native speakers is improved, but device cost, complexity, and susceptibility to theft or breakage increase
Solution Approach 1:
The patent uses optical copying by projecting caption images onto the back of seats using a projector. Instead of giving each audience member a complex electronic device, the system creates optical copies of captions that are visible on seat backs, dramatically simplifying the system while maintaining accessibility.
Solution Approach 2:
The patent extracts the caption display function from individual audience devices and relocates it to the seating infrastructure itself. By projecting captions onto seat backs, the system removes the need for personal electronic devices entirely, reducing cost and complexity.
2Adaptability or versatility
If RF or IR flood signals are used to transmit caption data to audience devices, then multi-language caption delivery is enabled, but signal leakage between auditoriums occurs
Solution Approach 1:
The patent replaces the electromagnetic RF/IR transmission system with a direct optical projection system. By using a projector to cast images onto seat backs, the system eliminates wireless transmission entirely, preventing signal leakage while maintaining multi-language caption delivery through optical means.
3Adaptability or versatility
If multiple caption streams are displayed on individual audience devices, then multiple language support is improved, but operational reliability decreases due to battery and device failure risks
Solution Approach 1:
The system projects optical copies of multiple caption streams onto seat backs simultaneously. Audience members can view different language captions by adjusting their viewing angle or using simple filters, eliminating the need for complex electronic devices with batteries and improving reliability.
Solution Approach 2:
The projection system serves multiple functions: it displays captions in multiple languages, provides viewing control through angle adjustment, and eliminates the need for individual electronic devices. This universal approach improves reliability while maintaining multi-language support.
4Ease of operation
If expensive personalized display devices are provided to each audience member, then individualized caption viewing is enabled, but cost and susceptibility to theft or breakage increase
Solution Approach 1:
Instead of providing expensive personal devices that can be stolen or broken, the system creates optical copies of captions on fixed seat back surfaces. These immutable, infrastructure-based displays cannot be stolen or easily damaged, eliminating these harmful factors while maintaining individualized viewing.
Solution Approach 2:
The patent merges the caption display function with the existing seating infrastructure. By projecting captions onto seat backs, the system combines two elements (seats and display) into one, eliminating the need for separate personal devices and reducing vulnerability to theft and breakage.
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
Enables cost-effective, durable, and efficient display of multiple captions or subtitles in different languages, improving accessibility for hearing-impaired and non-native language speakers without signal leakage, by using color and polarization filters to isolate each caption for individual viewers.
Implementation Method 1
A display is provided for showing at least two captions in at least one of different colors with different spectral ranges and substantially complementary polarizations
Implementation Method 2
The reflector includes a filter configured for viewing a caption on the display in reflection mode, with the filter being at least one of a color filter and a polarizer
Implementation Method 3
The reflector includes a filter configured for viewing a caption on the display in reflection mode, with the filter being at least one of a color filter and a polarizer
Data Source
AI summary
A system and method are disclosed for displaying different captions for selective viewing. A display is used for showing the captions in different color and/or polarization combinations, and color-selective filters and/or polarizers are used for separately viewing the individual captions.
