Dynamic Color Bar Codes for Billboard Information Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Billboard advertisements face challenges in conveying information effectively due to high speeds of viewers, making it difficult for interested individuals to record details like URLs or phone numbers, and existing static bar codes require precise orientation, limit flexibility, and reduce real estate for content display.
Innovation Solution
A system using dynamic sequences of colored light patterns that can be captured by mobile devices to automatically retrieve content, allowing for flexible updates, multiple advertisers, and increased information transmission capacity, while being more attractive and visible from a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If static bar codes are used on billboards, then information can be retrieved, but the billboard real estate for content display is reduced and flexibility is limited
Solution Approach 1:
The patent transitions from two-dimensional static bar codes to three-dimensional color-coded spherical objects that can be viewed and captured from multiple angles. This dimensional change allows the information encoding to occur in spherical color patterns rather than linear bar code strips, thereby reducing the space required on the billboard surface while maintaining information retrieval capability.
Solution Approach 2:
The invention uses color-coded spherical objects with distinct color patterns to encode information, replacing traditional black-and-white bar codes. This color-based encoding system increases information density within the same visual space, allowing more information to be conveyed without proportionally increasing the billboard area required.
2Loss of information
If static bar codes are used on billboards, then information can be retrieved, but adaptability and flexibility for updates are reduced
Solution Approach 1:
The patent replaces static bar codes with dynamic color-coded spherical objects that can be easily changed or updated. The spherical objects with distinct color patterns can be modified, added, or removed to adapt to different advertising needs, promotions, or information updates, providing significant flexibility and adaptability that static bar codes cannot offer.
Solution Approach 2:
The color-coded spherical objects serve multiple functions: they can encode different types of information through color patterns, be viewed from various angles, captured by mobile devices, and easily updated or replaced. This multi-functionality provides greater adaptability compared to traditional static bar codes which are limited in their encoding capacity and modification flexibility.
3Loss of information
If traditional advertising methods are used, then content can be displayed, but information retrieval requires precise orientation and manual recording
Solution Approach 1:
The patent replaces the manual mechanical process of reading and recording information with an automated optical system. Mobile devices with cameras automatically capture images of the color-coded spherical objects, and software algorithms automatically decode the color patterns to extract information, eliminating the need for manual writing or precise manual alignment.
Solution Approach 2:
The system enables self-service information retrieval where the mobile device and decoding software automatically perform the information extraction process. The spherical objects with distinct color patterns are designed to be easily captured and decoded automatically, allowing users to obtain information without manual intervention for recording or precise orientation adjustments.
