Designing AI-Supported Focus Groups: A Role x Modality Playbook
This paper synthesizes existing research on generative AI in live conversations to propose a methodological playbook for AI-supported focus groups, organized by AI roles (tool, co-host, host) and modalities (text, voice, embodied), while highlighting interactional trade-offs and open questions for future evaluation.

Imagine you are trying to understand how people feel about a new product. You could ask them one by one (like a solo interview), but there is a special magic that happens when you put a group of people in a room together. This is a Focus Group.
The magic isn't just that they tell their stories; it's that they react to each other. One person says, "I hate this feature," and another jumps in, "Oh, I actually love it because..." That back-and-forth, the arguing, the agreeing, and the "aha!" moments create a unique kind of insight that you can't get anywhere else.
However, running a focus group is like conducting a high-stakes orchestra. It's expensive, hard to organize, and it all depends on the Conductor (the Moderator). If the conductor is too bossy, the musicians stop playing. If they are too quiet, the music falls apart. They have to know exactly when to ask a deeper question, when to let silence sit, and how to make sure the shy violinist gets a solo without making the loud trumpet feel ignored.
The New Player: AI as the "Smart Assistant"
Recently, Artificial Intelligence (AI) has started showing up in meetings to help conductors. It can listen to everyone, count who is talking, summarize what was said, and even suggest questions.
But here's the problem: Researchers don't have a clear map yet. If you just throw an AI into a focus group, it might accidentally ruin the "magic" by making people feel watched or by shutting down the natural flow of conversation.
This paper proposes a Playbook (a rulebook) for using AI in focus groups. It suggests that you shouldn't just ask, "Can AI help?" Instead, you need to decide two specific things about how the AI acts:
- Who is it? (Its Role)
- How does it show up? (Its Modality)
1. The Role: Who is the AI?
Think of the AI's role like its job title in the room.
The Tool (The Backstage Crew):
- Analogy: Imagine a stagehand whispering suggestions into the conductor's ear. The audience (participants) doesn't see or hear the stagehand.
- What it does: It gives the human moderator private notes like, "Ask about the price now," or "We haven't heard from Sarah yet."
- The Risk: Even though it's hidden, it can still steer the ship. If the AI keeps suggesting questions about price, the group might ignore everything else.
The Co-host (The Visible Partner):
- Analogy: Imagine a second conductor standing next to the main one, waving a baton occasionally.
- What it does: It speaks up or posts messages to the group to say, "Let's hear from someone who hasn't spoken," or "Here is a summary of what we've said so far."
- The Risk: People might feel like they are being graded. They might start saying what they think the AI wants to hear, rather than their true feelings.
The Host (The Solo Conductor):
- Analogy: The AI takes the baton and runs the whole show. The human steps back.
- What it does: The AI decides who speaks, when to switch topics, and how long to talk.
- The Risk: If the AI makes a mistake (like interrupting at the wrong time), the whole group might get confused or stop trusting it. People might feel like they are being interrogated by a robot, which kills the natural "group chat" vibe.
2. The Modality: How does it show up?
This is about how the AI communicates with the group.
- Text (The Sticky Note):
- Analogy: The AI writes notes on a whiteboard or sends a chat message.
- Effect: It's quiet. People can ignore it if they want. It feels less like an interruption.
- Voice (The Shout):
- Analogy: The AI speaks out loud.
- Effect: It's hard to ignore. It feels more authoritative. If the AI says, "Let's move on," everyone stops. This is powerful but can feel bossy.
- Embodied (The Avatar):
- Analogy: The AI appears as a cartoon character or a robot on a screen.
- Effect: It feels like a real "person" is in the room. This can make people feel more watched and self-conscious, like they are performing for an audience.
The Big Warning: The "Group Effect"
The paper warns that the most valuable part of a focus group is the interaction between people. If the AI is too loud, too bossy, or too visible, people stop talking to each other and start talking to the AI or just waiting for the AI's next command.
If the AI makes people feel like they are being monitored or judged, they will stop sharing their honest, messy, real stories. They will give "safe" answers.
The Takeaway
This paper doesn't say "AI is good" or "AI is bad." Instead, it says: "Be careful how you mix the ingredients."
- If you want to keep the conversation natural, maybe use the AI as a Tool (whispering to the human) with Text (quiet notes).
- If you need to make sure everyone speaks, maybe use the AI as a Co-host with Voice (gentle reminders).
- If you let the AI be the Host with an Avatar, you might get a very structured session, but you might lose the spontaneous, human spark that makes focus groups special.
The goal is to use AI to help the human moderator do their job better, not to replace the human connection that makes the research valuable.
