Cyber-Enabled Display Encoding Human and Machine Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic displays, such as digital signs, are typically limited to a single display purpose and lack the capability to convey both human-readable and machine-readable information simultaneously, with machine-readable data remaining invisible to humans.
Innovation Solution
A cyber-enabled display system that uses light-emitting diodes to create an image with two underlying patterns changing at different rates, where the rapidly changing pattern encodes machine-readable data and the slower changing pattern encodes human-readable data, allowing for simultaneous human and machine communication without affecting human visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display shows only human-readable information, then human visibility is maintained, but machine-readable data cannot be conveyed
Solution Approach 1:
The display output is segmented into two distinct patterns: a first optical pattern that changes rapidly and encodes machine-readable data, and a second optical pattern that changes slowly and encodes human-readable data. This segmentation allows both types of information to be conveyed simultaneously through the same display medium without interfering with each other.
Solution Approach 2:
The display utilizes periodic action by changing the first optical pattern at a first rate and the second optical pattern at a second rate, where the first rate is faster than the second rate. This periodic modulation at different frequencies enables machines to decode the rapidly changing pattern while humans perceive only the slower-changing human-readable content.
2Loss of information
If the display changes patterns rapidly to encode machine data, then machine readability improves, but human visibility deteriorates
Solution Approach 1:
The display utilizes periodic action by changing the first optical pattern at a first rate and the second optical pattern at a second rate, where the first rate is faster than the second rate. This periodic modulation at different frequencies enables machines to decode the rapidly changing pattern while humans perceive only the slower-changing human-readable content.
Solution Approach 2:
The system dynamically adjusts the display by simultaneously maintaining two different change rates for the two optical patterns. The first pattern dynamically changes at a high rate for machine reading, while the second pattern dynamically changes at a lower rate visible to humans, creating a dynamic multi-layer information system.
3Reliability
If separate networks are used for machine and human communication, then communication reliability improves, but system complexity increases
Solution Approach 1:
The invention merges machine communication and human communication into a single display system. Both types of communication are combined in one optical output, with machine-readable data embedded within the same display medium that shows human-readable information, eliminating the need for separate physical networks or communication channels.
Solution Approach 2:
The display system achieves universality by serving multiple functions simultaneously: it acts as both a human-readable information display and a machine-readable data transmission device. This multi-functionality allows a single system to communicate with both human users and machines without requiring separate specialized systems.
