This article is aimed at Microsoft Admins and Tenant Administrators for enabling Collaborate in your organization
The Collaborate app is an innovative tool that facilitates seamless video communication between Microsoft Teams users and RealWear headsets. Designed with the unique needs of frontline workers in mind, this app provides a reliable and efficient means of connecting, whether for routine operations or on-the-spot troubleshooting. The app’s functionality is built around ease of use and quick accessibility, ensuring that critical connections can be made swiftly and without unnecessary complexity.
Core Feature: Quick Connect
At the heart of Collaborate is the 'Quick Connect' feature, which simplifies the process of linking RealWear headsets with Microsoft Teams users. This feature is especially valuable in environments where time is of the essence, such as in Operations Centres or when Subject Matter Experts need to provide immediate assistance. The Quick Connect function generates a unique code directly on the RealWear headset, allowing Teams users to connect effortlessly and without delay.
Core Feature: Inbound (introduced March 2025 - v2.0)
Introduced in March 2025, Collaborate now acts as a Teams extension, this means if you're logged in Teams users in your tenant can now call you direct, causing your headset to ring and flash, you can accept the call on your headset
Core Feature: Outbound User / Team Dialing (introduced March 2025 - v2.0)
You can now search for users to call or Teams to call and call them directly from the headset
From the Team menu, you can can call individual members in the team.
Collaborate Flow
The following diagram provides a detailed overview of the workflow within the Collaborate app as it operates on RealWear headsets. This workflow is divided into two distinct parts: the Android app running on the RealWear headset and the Microsoft Teams Addon app, each playing a crucial role in the overall operation.
