Booths/exhibits are a good option if a conference has them, but it's closer to an exhibition/expo than to a conference. They then act like a crystallization centers where people can gather in smaller groups and ask questions about the booth or tech being presented, about company, recruiting etc. It's like a small and short conference all to yourself or a very small group. That indeed works somewhat.

But usually such very big shows happen somewhere in the USA/UK/west Europe etc. And pricey. What I've seen in my country were usually a conferences structured like a series of talks with breaks. If conference is big then 2 or 3 treks in parallel in different room. In this case there is only one point of interest - the presenter, and maybe one or two previous or next presenters. It's not a problem to recognize presenter, a problem is talk to him/her longer than a single carefully prepared question and answer, because there are like 20 other people around all trying to talk to him/her.

If enough people want to talk to a presenter, the conversation usually moves outside the presentation room to allow more time. It is worth listening carefully to the questions of others in the queue, since you may meet someone with a question close to your interests.

Limited time is a challenge, but it's also good practice for developing a short pitch about a question or topic. If successful, the goal should be to exchange contact info with the presenter, for a longer discussion at the same conference.
