Guide for Remote Experts

This page is for the person on the other end of the call. You join from a desk, a laptop, or a phone. The fieldworker wears the glasses.

You install nothing. Assist runs in your browser at assist.iristick.app. You do not need an Iristick account.

What you need

  • A recent browser: Chrome, Edge, Firefox, or Safari
  • A microphone, and speakers or a headset
  • A room code or an invitation link from the fieldworker
  • A connection of at least 1.5 Mbps up and down

On a strict company firewall, check network requirements first. Assist needs UDP 3478 open. If that is blocked, it falls back to HTTPS on 443.

Joining a session

How you join depends on whether the call has started.

When you join How
First expert, before the call runs Enter the room code at assist.iristick.app
After the fieldworker and first expert connect Open an invitation link. The room code no longer works.

The room locks as soon as the fieldworker and the first expert are connected. After that, knowing the room name is not enough to get in. You need an invitation link from someone already in the call.

The first expert to join becomes the main expert and holds the controls. Anyone who joins later is a guest. A session holds one fieldworker and up to three experts.

The video feed

You see what the fieldworker sees, in Full HD. Assist sets the resolution and bitrate from the live connection. You do not pick a quality setting. When bandwidth drops, small text like a nameplate or an error code stays readable.

Open the quality detail view during a call to see what the connection is doing. The signal bars follow the live uplink, so a connection that settles at a bad level shows up straight away.

As main expert you can zoom the video. You can also drive the optical zoom on the glasses camera.

Pointing

Press and hold anywhere on the video. The frame freezes and a cursor appears where you point. The fieldworker sees that same cursor on their heads-up display, so you do not have to describe what you mean.

Drag while holding to move the cursor. Let go and the live video comes back.

Nothing is saved. Each point is separate.

Only the main expert can point. Guests see the frozen frame and the cursor, so everyone looks at the same thing. Control stays with one person on purpose. Two people grabbing the same frame helps nobody.

Tip

Freezing the frame is useful in itself. The fieldworker can move or look away while you keep studying the still image.

Drawing

When pointing is not enough, draw. You can mark a frozen frame with arrows and circles, in green by default. The fieldworker sees your marks on their heads-up display.

You can also draw on a full-resolution photo you took earlier. That works better when the detail matters, like a part number or a corroded terminal. A still image is easier to read than a moving one.

Drawing needs a license. See licensing.

Capturing photos

Press the take picture button and the glasses camera fires. You do not have to ask the fieldworker to do anything. They keep working while you capture what you need.

The photo is taken at once. It reaches you over the same encrypted link as the video. Uploads are throttled, so sending a photo does not stall the live feed.

Each photo opens in a preview with a download button.

The fieldworker can also take a photo by voice. That helps when they spot something you have not asked about.

Download photos before the call ends

Photos only exist while the session runs. When the call ends they are deleted from both devices at once. Iristick has no copy. Download what you need while you are still on the call.

Sharing your screen

You can share your own screen back to the fieldworker. A wiring diagram, a manual page, a maintenance record. It appears on their heads-up display. Showing someone the schematic is often faster than talking them around it.

Screen sharing needs a license. It works on desktop browsers only. Mobile browsers cannot capture a screen, so the button is hidden on a phone or tablet.

The pointer keeps working while you share. Using it switches the fieldworker's view back to the camera for a moment, then returns to your screen.

Inviting colleagues

Open the invite control to generate a link, then send it through any channel you use. The panel shows how many expert slots are free.

You keep control of the link after you send it:

  • Re-copy a link you lost
  • Revoke one you sent to the wrong person
  • Links expire on their own if nobody uses them

If the room is full, remove someone before inviting another person. Inviting extra experts needs a license.

Managing participants and handing over

The participant panel lists everyone connected, with their role and connection status. As main expert you can remove a guest. Removing one person does not end the call for anyone else.

Before you leave a call that still has other experts in it, you pick a successor. The hang-up flow asks who should take over. Your browser also warns you before you close the tab, so you do not drop out by accident.

If your connection dies, Assist waits a few seconds for you to come back. If you do not, the next expert by join order takes over and is told so.
