Stage

Beam from phone

liveForTeaching staff

Take a photo with the phone and throw it directly onto the slide — via QR code, without cables and without signing in on the phone.

Why#

A sketch on paper, a board drawing, an object: what lies in front of you is on the slide within seconds.

How it works#

  1. 1In the slide editor choose “Insert” → “Beam (phone)” (in the workshop also in the box “Sources” under “BEAM” → “Start BEAM”) (Fig. 1).
    Fig. 1 The box “Sources” with “Start BEAM”: photos from the phone directly onto the slide.

  2. 2Drag the dashed beam frame to where the photo should land and drag it to size.
  3. 3Scan the QR code with the phone. A page opens on the phone: “📷 Choose / take photo”.
  4. 4The photo appears in the frame; on the phone it says “Sent!” — further photos can be sent afterwards.

Settings and switches#

No switch of its own in the feature catalogue — the feature belongs to its surroundings.

  • Part of the module “Course Studio”.

Why this is safe without signing in on the phone#

The QR code carries a short-lived token signed by the server. It is the permission — nothing more: whoever has it can send photos for this one session but read nothing. After 15 minutes it is worthless.

Who may do what#

Start: the signed-in author in the editor. Send: whoever scans the QR code while it is valid.

Tips#

  • The link is only valid briefly (15 minutes) and is bound to the editor session that is currently open; afterwards simply start a new beam.
  • In the editor's history a beamed photo appears as a step of its own (“Beam photo”) — it can be undone like any other change.
