Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Participants in virtual conferences often inadvertently turn on their cameras or microphones, risking the leakage of sensitive information due to accidental button presses or unauthorized access, especially in scenarios where privacy is a concern.

Innovation Solution

Implementing a multi-step enablement process for media input devices, such as cameras and microphones, which requires users to provide additional information or perform specific actions to confirm their intent before enabling these devices, thereby preventing accidental activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single-step enablement process is used for media input devices, then the ease of operation is improved, but the reliability is worsened due to accidental activation

Engineering Contradiction:

Improveease of enabling media devicesVSAvoidaccuracy of user intent

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs a preliminary confirmation action by displaying a visual indicator and requiring a separate confirmation input before enabling the media input device. This preliminary step ensures that the activation is intentional while maintaining ease of operation through a simple two-step process.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a multi-step enablement process is implemented, then the reliability is improved by preventing accidental activation, but the ease of operation is worsened due to additional steps

Engineering Contradiction:

Improveaccuracy of user intentVSAvoidease of enabling media devices

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system provides visual feedback by displaying an indicator that shows the media input device will be enabled upon receiving the confirmation input. This feedback mechanism guides the user through the process and confirms the system's response to their action, making the additional step intuitive and easy to understand.

Inventive Principle:

Principle #23Feedback

3Loss of information

If visual indicators are displayed during the enablement process, then the information provided to users is improved, but the device complexity is worsened

Engineering Contradiction:

Improveuser awareness of activationVSAvoidcomplexity of enablement system

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The visual indicator serves as an intermediary element that communicates the system's state and intended action to the user without requiring complex interfaces. This simple visual mediator provides clear information about the enablement process while keeping the overall system complexity low.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Systems and methods for enabling a media input device configured with multi-step enablement are disclosed. A client device joins a video conferencing session and disables a media input device at the client device. A setting of multi-step enablement for the media input device is activated during the video conferencing session. The client device generates a prompt for a subsequent enabling action in response to an initial enabling action during the video conferencing session. The client device compares a received subsequent action to a reference answer corresponding to the prompt to generate an enabling decision. The client device enables the media input device in response to the enabling decision if the received subsequent action matches the reference answer corresponding to the prompt.
