Projector, projector control and overlay

LehrPuls shows the picture for the room in a separate projector window. It opens by itself when a session starts (you can switch this off under Settings → Session & projector); the Projector switch at the bottom of the sidebar shows and hides it at any time, and the cross on the window only hides it. Drag the projector window onto the projector and keep the cockpit on the laptop. What is on the wall right now is shown in the purple On the projector line in the center of the live cockpit.

With the main button (or the space bar) you open the question. The projector shows the title, question text and answer options; at the bottom it counts the submissions. The join QR code moves small into the corner so latecomers can join at any time. Which answer was chosen how often, the room only sees at the reveal.

After Close, LehrPuls accepts no more answers; the projector keeps showing the question, and at the bottom it reads “Submissions closed”. This way you can still talk about the question before showing the result.

1. Submissions closed

Show results shows the distribution as bars and highlights the correct answer. The model solution only appears when you ask for it: after the reveal, the Show on projector button sits below the question in the cockpit.

With + and − (buttons or keys) or with Ctrl or ⌘ and the mouse wheel you zoom the wall — up to 2000 %, with the wheel towards the mouse position. With the wall zoomed in, dragging with the mouse pans the view, as do the arrow keys; unzoomed, Page Up and Page Down page through a long wall. The second picture shows the projector: it follows projector control exactly. Full view or the 0 key resets everything.

3. Full view

A click in projector control on an image, a formula, a table or the model solution brings exactly that element up full screen on the wall — here the model solution with the voltage divider formula. The pointer then shows a minus, and a second click brings back the whole wall. Every new piece of content on the wall starts in the full view again anyway.

Two questions have already run and been revealed; the wall shows the results of the second one. Click the earlier question on the left. In the center, Your view shows it with the Played badge, and its heading carries the Look-back on the projector (B) button — the B key does the same, in the simple view too.

11Earlier question22Look-back on the projector (B)33On the projector

1. Earlier question
2. Look-back on the projector (B)
3. On the projector

The projector shows the earlier question with its results, just as they stood back then; the join QR code stays in the corner. The smartphones (second picture) stay unchanged on the current question — the look-back affects the wall only.

The On the projector line now reports “Look-back: …”, and the button at the question reads Remove from projector (B) — it brings the picture back to the running question. If the question has a model solution, the On the projector line also offers Show model solution: the solution then appears on the wall only; the devices do not receive it.

11“Look-back: …”22Show model solution33Remove from projector (B)

1. “Look-back: …”
2. Show model solution
3. Remove from projector (B)

The model solution now appears below the question, and the On the projector line adds “with model solution”. Hide model solution in the same line removes it again. This works the same for the preview and for look-backs from earlier sessions.

11Model solution

1. Model solution

Click a question that has not come up yet: the button then reads Preview on the projector (B). This way you announce a task or read it together before opening it. The selected question is highlighted in yellow — the main button would open it next.

11Upcoming question22Preview on the projector (B)

1. Upcoming question
2. Preview on the projector (B)

The projector shows the question the way participants will see it — without results. It is not open yet; nobody can answer yet. Remove from projector (B) ends the preview.

1. Answer options

The question appears on the wall with its result from back then; projector control stays open and shows the same picture. Here, too, the devices stay on the current question.

Whatever you bring to the wall over the running question — look-back, preview, model solution, a board — is taken down again by Clear the wall; the button is in projector control and in the On the projector line, but only while something is shown. There is only ever one insert on the wall: bringing up something new takes down the previous one, and opening a question clears every insert.

Pause stops the time display and the timer of the open question. The projector shows a calm break screen with the join QR code for latecomers. The remaining time is kept: no countdown runs on the devices or on the projector during the break.

In the cockpit the button now reads Resume, and the remaining-time ring is gray and frozen. Resume continues the time display and the timer exactly where they stood. If you open the next question instead, the break ends by itself.

Presenting is for switching to a longer stretch with your own slides. A question that is still open is closed, the projector and the devices go back to the start screen, and the time display stops. The join QR code stays, so latecomers can still join; the smartphones (second picture) show “About to start”.

While presenting, the header button reads End presenting, and Pause is hidden. You simply continue with the main button: it opens the next question, and presenting ends by itself.

After the reveal, LehrPuls offers End discussion as soon as nothing is open any more. It is the small gesture for a transition: the question and its results disappear from the projector and the devices, and the time display keeps running. As a rule of thumb: End discussion for a short transition, Presenting for a longer stretch without questions, Pause when the running question should continue exactly where it stood.

11End discussion

1. End discussion

The question and its results have left the wall. You open the next question with the main button as usual.

In the playlist’s start dialog, switch on Discussion round (no devices) and click Start session. Allow recap and Follow-up disappear, because without devices there is nothing to recap. How to open the start dialog is shown in the guide Running a session.

The projector shows no QR code, code or address — only a note that the questions will appear here.

11Note instead of join details

1. Note instead of join details

The header carries the Discussion round badge; code, join address and participant count are missing. The Allow participants button switches to a regular session at any time — you do not have to end and restart anything.

The main button opens the question as usual. The wall shows it without a submission counter and without a QR code in the corner — room for the conversation in the hall. Devices that are already connected still receive the question and can answer.

In the All view, the right column offers the Plenary answer while a question is open: for choice questions you tick together with the room, and every tick appears on the projector right away; it is saved when you close or reveal. Text and numbers only reach the wall with Show on projector. In the analytics the plenary answer is marked and does not count in the statistics. It is available in every session, also with connected devices.

After Allow participants, the join QR code is back in the corner, and participants can join and answer. The button then reads Discussion round again; connected devices stay connected with every switch.

11Join QR code

1. Join QR code

During a session, the button with the picture-in-picture icon in the On the projector line moves the overlay on: off, small, large, off again. It is filled while the overlay is visible. The keyboard shortcut ⌘⌥L (Mac) or Ctrl+Alt+L (Windows) does the same — even while your presentation is in front. If another program already uses the shortcut, LehrPuls tells you once; the button still works.

11Overlay: off, small, large

1. Overlay: off, small, large

In the All view, the ⋮ More actions menu sits below the main button. The Overlay on your presentation entry moves it on in the same way and shows the current state and the shortcut. In the same menu, Open control view opens projector control.

11Overlay on your presentation22Open control view

1. Overlay on your presentation
2. Open control view

Under Settings → Overlay on your presentation you choose the corner for the small card (default: bottom right) and the screen the overlay appears on: Same as the projector window (default) or Main screen. To do so, drag the projector window onto the projector once — it does not need to be visible. Both apply to this computer; a running session picks up a change right away.

11Corner of the small card22Screen

1. Corner of the small card
2. Screen

The first click (or ⌘⌥L or Ctrl+Alt+L) shows a small card in the chosen corner on top of your presentation: the QR code, the code and the join address for latecomers, the number of connected devices and, while a question is open, the answers (“Answers 2 / 3”) and the remaining time, which turns red from ten seconds. In a discussion round, code, QR code and address are left out. The card does not take the focus away from your presentation and lets mouse clicks through: arrow keys and presentation clickers keep controlling your slides.

The second press replaces the card with exactly the picture of the projector window, in a dark frame at the bottom center — here the running question, later its results. The room sees the question and the result without you leaving your slides. The third press hides the overlay again.

While the overlay is visible, the button in the On the projector line is filled; in the large step it carries a different icon. One more click switches the overlay off. Ending or suspending the session removes it by itself, and the keyboard shortcut is free for other programs again. If a presentation does not show the overlay in full screen, run the slide show in a window (manual, section 6.6).
