Solution Overview

Problem

Existing videoconferencing systems lack efficient access for participants to project content from their computing devices into the videoconference, often requiring complex authentication steps and manual setup.

Innovation Solution

A method and system that allow a computing device to detect proximity to a videoconferencing system using technologies like WiFi, Bluetooth Low Energy, and audio tokens, enabling automatic authentication and initiation of videoconferences without the need for manual steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specialized software and manual authentication steps are used for videoconferencing, then security and control are improved, but ease of operation deteriorates

Engineering Contradiction:

Improvevideoconferencing securityVSAvoidparticipant access

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables participants to automatically authenticate and join videoconferences by simply being in proximity to the videoconferencing system. The computing device detects the videoconferencing system automatically and initiates connection without requiring manual authentication steps, allowing the system to serve itself rather than requiring user intervention for security procedures

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces an intermediary mechanism (proximity detection system using WiFi, Bluetooth, or audio tokens) that mediates between the participant's computing device and the videoconferencing system. This intermediary automatically establishes the connection based on physical proximity, eliminating the need for participants to directly interact with complex authentication software while maintaining security protocols

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If multiple authentication steps and manual setup are required, then system control is improved, but productivity deteriorates

Engineering Contradiction:

Improvevideoconferencing controlVSAvoidvideoconference setup speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary authentication and connection setup actions automatically based on detected proximity. Before the participant even attempts to join a videoconference, the system has already detected the computing device and prepared the connection, eliminating the need for manual setup steps during the actual videoconference initiation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent allows the authentication and connection establishment process to be skipped entirely by using proximity-based automatic detection. Instead of rushing through multiple manual authentication steps, the system bypasses them completely by automatically establishing the connection based on the participant's physical presence near the videoconferencing system

Inventive Principle:

Principle #21Skipping (Rushing through)

AI summary

In one general aspect, a method can include displaying, on a display device included in a computing device, content in an application executing on the computing device. The method can further include displaying, in a user interface on the display device, at least one identifier, receiving a selection of the at least one identifier, and initiating casting in response to receiving the selection of the at least one identifier.
