Players (i.e. the training audience) can interact with your exercise via any device with a web browser. After log in they'll see a virtual desktop like the one shown below. Note that all the channels are configurable by you: you decide which channels to use, how they should be named and what icon should represent them and more.
On a mobile device, access to channels is via a familiar "hamburger menu" on the top left.
