How to make your presentation interactive with no app on the audience's phones

The short answer: a presentation becomes interactive when the audience can answer from their phones without installing anything. In Engage Decks a code appears on the screen, each attendee scans it with their phone camera, the participation page opens in the browser, and they vote, answer and ask, with every answer landing on the big screen as it arrives. All you need is a deck with questions in the right places, a screen, and the phones already in the room.

Why do most presentations fail to involve the audience?

Because they are built for the speaker, not the room. Slides are shown, the audience listens, and the only question comes at the end: “Any questions?” Nobody answers. The problem is not the content but the direction: information travels one way.

Real interaction flips the direction. When an attendee votes, types a word or picks an answer, they become part of the presentation, and they stay attentive because they are waiting to see the effect of their input on the screen.

What do you need for an audience to take part with no app?

Only three things:

1. A screen or projector showing the deck, with the join code on it.
2. The audience’s phones with any browser. No app, no account, no email.
3. A deck with interactive slides at the points where you want the room to take part.

The old way asked people to download an app or sign up on a website. Half of them never do, and the other half lose minutes installing. The newer way is a link that opens in the browser: scan a code, a page appears, a question waits for an answer.

How do you build an interactive deck, step by step?

Start from your idea or from the deck you already have

You have two options:

• Type the idea of your talk in a line or a short paragraph, pick the tone, and the full deck is built with its slides, its questions and an art theme that fits the room.
• Upload the deck you already have as it is, then ask for Suggestions. The slides where interaction would fit are proposed, and you accept the ones you like.

Put the interaction in the right place

The simple rule: a question at the start to wake the room up, a quiz after each part you explain, and an open question before the end.

Type of interaction	When it fits
Poll	In the first minutes, to learn who is in the room and what they expect
Word cloud	To collect impressions or ideas in one word from everyone
Quiz with points and a leaderboard	After explaining a part, to check what landed, with a competitive spirit
Brainstorm	When you want many ideas in a short time
Audience questions	So people can type their questions at any time, and you answer when you choose
Random picker	To choose a volunteer or a winner without awkwardness

Pick a theme that suits the room

The art theme changes the feel of the whole deck. Pick one in a tap, and if you want your organisation’s identity, paste your website link and your logo and colours come with it, on every phone in the room too.

Edit with a sentence

If you want to change a slide, add an image, a chart or a new question, ask Engage AI in a sentence inside the editor and it makes the change without rebuilding.

What does it look like in the room?

You open the deck on the screen and the join code appears. You tell the audience: “Scan the code.” Within seconds you see the number of people joining go up. You reach the poll slide, and the options appear on the screen and on their phones at the same time. They choose, and you watch the bars move in front of everyone. You move on to your explanation, come back after a part to a quiz, the leaderboard appears, and you hear the room laugh.

Interaction is not decoration added at the end. It is what makes the audience remember what you said a week later.

Tips from real sessions

• Don’t overdo it. One question in the right place beats five in a row.
• Show the result and comment on it. People take part to see what happened, so never pass over a result in silence.
• Make the first question easy. A light poll at the start breaks the ice, and the harder questions come after.
• Test the code before the session. Open it from your own phone once, to make sure the screen is clear and scanning works from the back of the room.
• Keep the results. Export the interaction results after the session. They are the most honest measure of what reached the audience.

After the session

Nothing is lost. The poll and quiz answers export to a spreadsheet, and the deck itself downloads as PowerPoint or PDF with its design and images, to share with those who could not attend.

Start with your next talk. It begins free, and your audience needs nothing but their phones.
