    • If you see neither the link nor the button, then you are most likely missing privileges - in this case please contact support.math.uzh.ch.
  3. The form shown in the image below below appears.
    • create_event_general.jpg

    • a) Type: The type of event: Lecture, Exercise or Seminar. If you pick exercise, then you will also have to select the lecture or seminar for which the exercise is done.

Click the + Button to create the first occurrence of the event. Then configure the occurrence (which is called a meeting here):

Click Repeat this meeting. The form in the image below will open. To create the remaining 13 occurrences of the event, configure the as shown:


Once this form is saved, multiple meetings are created using the chosen options. You will land on the Detail page of your event. If everything went right, you should see this message:



Starting the Stream (Speaker / Assistant)

The event can be streamed once its schedule has been created. The speaker of the event can turn on (and off) devices in the room with the click of a button. This can either be done in a browser (e.g. on a laptop or computer) or on the SeminarLive touchpad. Both ways are described below.

In the Browser

  1. Navigate to the My Events page (Login required)

  2. a) Click the Join Button on the left side in the 'Today's Meetings' section

    todays_meetings.png b) OR: alternatively you can open the detail page of your event by clicking the magnifying glass. On this page you can see the whole schedule of your event. At the top, in the 'Upcoming' section, you can click 'Join' to open the streaming page. event_detail.png upcoming.png

  3. Click the button shown in the picture below. You will now see all devices in the room which can be turned on and off. Toggle the switches next to the device's name to turn it on/off.


On the Touch

  1. Log in by holding your UZH card to the backside of the Touch. If this is the first time you are using your card to log in, you will be prompted to enter your UZH/SeminarLive username and password. Otherwise you will be logged in immediately. Alternatively, you can log in without your card, by clicking 'Login' and then entering your UZH/SeminarLive username and password.
  2. Join the 'Meeting' by clicking 'Join'.


  1. Toggle the button next to a device's name to toggle it on or off. The device's stream (e.g. the blackboard camera) will be visible in the meeting a few seconds after turning it on.


Streaming Interface

The streaming interface for SeminarLive looks and works as shown and explained below.


  • a) Mute / Unmute yourself. The first time you unmute yourself, your browser will ask for permission to access your microphone. Confirm this with yes. When you are unmuted, you can also adjust your own volume.

  • b) Share your camera (e.g. built in camera of a laptop/mobilee device or a webcam)

  • c) Share your screen. You can share multiple screens simultaneously. Please note that screensharing might not be possible on tablets and mobile phones.

  • d) Show Devices in the Room such as Blackboard Camera, Ceiling Microphones, etc. By turning a switch, each device can be turned on / off individually. This option is only available to the host.

  • e) Raise Hand. Click this to signal that you have a question. Other participants will see the hand icon next to your name. You can click it again to lower the hand. The host of the meeting is able to lower any hands.

  • f) Follow Speaker. If you turn Follow Speaker mode on, then you will always see the stream which is currently selected by the speaker. This is useful if the speaker is using multiple streams (e.g. Camera, Blackboard, ...) to explain something. If this is turned off, then you will have to manually click on a stream's thumbnail to see it in high quality.

  • g) Show/Hide Participant Panel Click this to show/hide the panel with all participants in the top right.

  • h) Show/Hide Chat Panel Click this to show/hide the chat.

  • i) Leave Meeting Leave the meeting and return to the previous page

  • j) Enter Fullscreen. Leave Fullscreen by cliicking the icon again or by hitting ESC.

  • k) Search Participant in the list below

  • l) Participant Panel Settings Contains an option to quickly expand/collapse all stream thumbnails. More options will come in the future.

  • m) Shows the Role of a participant. White speeach bubble = Speaker, golden speech bubble = host.

  • n) Mute or unmute another user. This has no effect for other participants, only for yourself.

  • o) Participant Settings. Contains multiple settings: Adjust volume of participant, grant/revoke speaker privilege (Host only), more settings in the future.

  • p) Thumbnail. The thumbnail of a stream that is shared in the meeting. Thumbnails appear for cameras and screenshares. They can be clicked to display the high quality stream. The arrow symbol in the top right corner of the thumbnail can be clicked to expand or collapse the thumbnail.

  • q) Chat

Known Problems

  • Audio / Video Shift
    • Livestream: there is a 1-2 second shift between video and audio. One reason is the 4k blackboard camera - this is hardware related.
    • Recording: unfortunately the shift between video and audio is not constant (it seems there is a relation between shift and length of the recording).
  • Apple Safari
    • We have reports from Apple Safari users about audio breaks in recordings every 1-2 seconds - Google Chrome seems to be fine.

To be implemented

  • Speaker remote, student on-site: starting beamer and audio in seminar room from remote - we're working on it, should be ready in the first weeks of HS22.
  • Automatic import of student per lecture.
  • Unattended start / stop of recording
  • Offer access to recordings after a defined period of time (students should not have access to the recordings on the same day).
  • Chat: Emoticons (for votes)
  • Rooms to be installed: Y27H26
