Can you remember what it was like to sit down and talk to someone, face-to-face? For many of us, 3D interactions are a distant memory as we’re consigned to communicating and collaborating with our colleagues, friends and family through a 2D screen.
For the world’s videoconferencing platforms, this has been a golden age and Zoom is now synonymous with the world of online communications. At its peak the company counted more than 300 million daily participants in virtual meetings, while the number of paying customers has more than tripled.
But Zoom isn’t the only platform out there, and it’s rise in popularity does not necessarily dictate its dominance in the user accessibility and compatibility stakes. Microsoft Teams, for example, has seen a similar surge in popularity with the number of daily average users doubling to 75 million during April 2020, compared to March 2020. Other video platforms have reported similar levels of growth during lockdown.
In our latest research, we’ve compared three of the largest video conferencing platforms in the world: Zoom, Google Hangouts and Microsoft Teams. Focusing on the point of entry for each platform, we considered the accessibility of their homepages and their compatibility across different browsers and devices.
Each platform is assessed based on their performance across these two fields. The winner is the videoconferencing platform that performs best across these accessibility and compatibility tests. Here are the results.
The Accessibility Battle
Accessibility is key for any web-based platform, where individuals must be able to seamlessly understand, navigate and interact with the site or application they’re using. At Digivante, we regularly perform accessibility testing for our customers to cover the many issues that may prevent or discourage disabled users from using or purchasing from their site.
For this assessment, we ranked the videoconferencing platforms based on five fundamental accessibility areas: Controls and Forms, Design and Usability, Interaction, Structure and Layout, and Multimedia Accessibility.
We usually use a range of test cases when we conduct accessibility tests for our customers. For this specific assessment, we chose one specific test case and ran it against each homepage of the videoconferencing big-three.
The result? Google Hangouts and Microsoft Teams only failed on 1/5 tests. But Zoom failed on 3/5 tests.
For Google Hangouts, the platform did not have available alt text for some of its non-text content. This makes it impossible for screen readers and browsers to describe images and other multimedia content to users who are unable to see them.
Microsoft Teams failed on Design and Usability, where the homepage’s navigation breaks if you turn off CSS in the browser.
Zoom failed on three fronts. We observed nine errors across its Controls and Forms, including missing labels. The platform’s keyboard interaction also contained errors when selecting a button in the banner area of the homepage. Finally, the homepage also lacked alt text content.
Verdict: we ranked Microsoft Teams in first place. The Microsoft Teams’ issue relates to an AA standard, which is best practice but not a legal requirement. Therefore, Microsoft Teams performed better against the industry standards, compared to Google Hangouts, who ranked second. Zoom had three major issues and is the clear loser in this battle.
The Compatibility Battle
Compatibility tests check that a website performs as expected across a range of devices and platforms. For this assessment, we selected five popular smartphone devices and four web browsers, running the same test case for each videoconferencing platform’s homepage. For this test case, a guest user navigated to the homepage and then accessed the login section.
The result? Google Hangouts and Microsoft Teams both scored a perfect 9/9 with no issues raised against any of the tests. Zoom passed on 6/9 tests where the homepage’s carousel broke on three smartphone devices.
Verdict: with no compatibility issues, we ranked Google Hangouts and Microsoft Teams joint first. Zoom was ranked in third place.
And the winner is…
This was a difficult call, with little to choose between Google Hangouts and Microsoft Teams. However, coming first for Accessibility and joint first for Compatibility, we crowned Microsoft Teams as our winner. Google Hangouts came a close second and Zoom was a distant third.
