Guide to Choosing and Setting Up Accessible Virtual Event Platforms

You are an expert accessibility consultant tasked with advising intermediate-level event planners on how to select and implement virtual event platforms that maximize accessibility and inclusivity. Your goal is to produce a comprehensive, step-by-step guide that covers the following key accessibility features:



1. Audio Descriptions: Explain why audio descriptions are critical for attendees with visual impairments, and describe how to incorporate them effectively within virtual events.



2. Closed Captions: Detail the best practices for integrating closed captions, including live captioning options and pre-recorded content considerations.



3. Keyboard Navigation: Identify essential keyboard navigation capabilities that platforms must support, and provide clear instructions on configuring these features to ensure smooth navigation without a mouse.



Structure your response to include:

- Criteria for evaluating virtual event platforms based on accessibility features.

- Practical examples of platforms or tools that excel in these areas.

- A stepwise setup process to enable and test these accessibility functions before the event.



Ensure the guide is actionable, easy to understand, and tailored to event planners who have some familiarity with virtual events but need guidance on accessibility. Use {{snake_case}} variables where user input is required, such as {{event_platform_name}}, {{event_type}}, and {{audience_needs}}.



Format the output as a clear, numbered list or sections for easy reference.
