Solution Overview
Problem
Existing optical datagram transfer methods require human interaction, which is inefficient and exposes users to biohazards, and RF-based wireless technologies are insecure and detectable, violating privacy and security regulations.
Innovation Solution
An autonomous, 'hands-free' optical communication method using control signals transmitted via photodetectors and video capture devices on mobile devices to initiate, adjust, and terminate data transfer sessions without human intervention, ensuring security and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If optical datagram transfer requires human interaction to initiate and control, then users can manually control the transfer process, but efficiency is reduced and users are exposed to biohazards
Solution Approach 1:
The system enables autonomous optical datagram transfer where the transmitting device automatically presents datagrams and the receiving device automatically captures and processes them without requiring manual user actions. The devices self-coordinate the transfer session, eliminating the need for users to physically handle or manually control the process, thereby improving efficiency while preventing biohazard exposure.
2Reliability
If RF-based wireless technologies are used for data transfer, then communication range is extended, but security and privacy are compromised due to detectability
Solution Approach 1:
The system replaces RF-based wireless electromagnetic communication with optical communication using visible light. Optical signals are inherently more difficult to detect and intercept compared to RF signals, providing enhanced security and privacy. The optical datagram transfer occurs through direct line-of-sight communication between devices, eliminating the electromagnetic detectability issues associated with traditional wireless technologies while maintaining reliable data transfer.

Data Source
AI summary
A method and apparatus to control optical communication between proximal devices, providing autonomous data transfer sessions that include optically-represented datagram (e.g., QR Code™) presentations, is disclosed. Optical control signals sent between a viewing device and a presenting device enable control of the presenting device without physical contact during initiation, performance, and termination of the transfer session. Advancement between datagrams is provided by control signals indicated by changes in relative orientation, changes in relative position, and gestural relative motion between the proximal devices.
