How to run a virtual poster session your members actually open

Two versions of the same session

The first version: a Zoom room with breakout groups, one per poster, where a handful of presenters wait in silence for visitors who mostly never arrive. Societies ran a lot of these in 2020 and members remember them, which is part of why "virtual poster session" still makes some program directors wince.

The second version looks different. The gallery opens ten days before the meeting. A member in Manchester searches it for her subspecialty, bookmarks six posters, and sends one to a colleague. She asks two authors questions from her phone, gets answers before the meeting starts, and when the education committee meets in the fall, the director can show which topics drew the most reading time. Same format on paper. Completely different outcome, and the difference is built weeks earlier, in how the posters get in and where they live.

Start inside the call for papers, not beside it

The most common failure in virtual poster programs happens before any attendee touches them: the poster track runs on a separate tool from the abstracts it came from. Accepted abstracts get exported to a poster vendor, then every late acceptance, title correction, and withdrawal has to be applied twice. By meeting week the gallery and the program disagree about something, and a member notices.

Run the poster track as a session type inside the same call for papers as your platform sessions. The committee reviews in one place, acceptance writes the poster number and session assignment onto the same record the agenda reads, and there is no export to drift.

Collect the poster the way you collect a bio

Authors are the volume problem. Nine hundred accepted posters means nine hundred people who each owe you a file, a consent decision, and a disclosure statement, most of them presenting for the first time and none of them reading your instructions email.

Put the upload where the author already goes. If poster authors use the same speaker portal as your faculty, the poster upload sits next to the bio and headshot they were going to submit anyway. Consent belongs at that door, not in a separate form: the author grants (or declines) publication permission as part of the upload, versioned, so the question "did we have the right to publish this?" has an answer with a timestamp. Disclosures ride along the same way and display on the published poster.

Two policies save you pain later. Decide the embargo rule before uploads open, because late-breaking science often can't appear before its release time, and a teaser mode (title and authors visible, poster hidden until the hour) beats keeping the whole gallery dark. And make withdrawal a status, not an email, so a withdrawn abstract disappears from the gallery on its own.

Make the gallery worth opening twice

A folder of PDFs is technically a virtual poster session. Nobody opens it twice. What earns the second visit:

Search that answers clinical questions. Members look for topics, drugs, techniques, and author names. If the search can't find "all posters on anticoagulation," the gallery is a filing cabinet.

Posters that read well on a phone. Crisp rendering with zoom, because a four-foot poster on a five-inch screen is where most reading now happens. A plain-language summary above the poster helps the attendee triage in ten seconds whether this one deserves five minutes.

A path to the author. Ask-the-author turns a static file into the conversation the format was invented for. Questions arrive asynchronously, which suits an international membership spread across time zones better than a fixed Zoom hour ever did.

Program context on every poster. Poster number, session, track, presentation time. The gallery should feel like part of the meeting, on your brand and your domain, not a vendor microsite with your logo in the corner.

This is the shape of Sessionboard's poster gallery: one link, instant search, AI summaries, ask-the-author, and QR signage that connects the physical hall to the same gallery remote attendees use.

Give the live hour a job

If you schedule synchronous time, give it a purpose the gallery can't serve alone. Moderated sessions where each presenter takes three minutes and a discussant leads questions work well. Judged award rounds work well, since judges can score from the gallery beforehand and use the live window for finalists. Assigned author hours, where a poster's ask-the-author queue gets answered live, work for large programs. Unstructured "drop into my breakout room" time is the version members remember badly. Skip it.

Close the loop with numbers

After the meeting, the gallery keeps working, and so should you. Three reports earn their keep. Most-viewed posters by track tell the program committee what the membership leaned toward. Author question volume shows where conversation concentrated. Zero-result searches are the quiet gift: a list of things attendees wanted that this year's program didn't carry, which is about as direct as input for next year's call for papers ever gets.

Members renew on the feeling that the association is where their field lives. A poster gallery that stays open all year, searchable, with last year's science still answering member questions in February, makes that argument for you at no extra production cost.

FAQ

How do you host a virtual poster session?

Run the poster track through your call for papers, collect uploads and publication consent through the author portal, publish the accepted posters to a searchable online gallery, and schedule presenter Q&A windows on the program. The gallery opens before the meeting, carries the hall during it, and stays available to members afterward.

What does a virtual poster session need to include?

A searchable gallery attendees can open on any device, posters that render crisply with zoom, a way to ask the author questions, visible disclosures, and program context (session, track, poster number) on every poster. Engagement analytics matter too, because the committee will ask what got read.

When should the virtual poster gallery open?

Before the meeting, once embargo rules allow. Attendees who preview posters plan their hall time around specific authors, and remote registrants get real access instead of an afterthought. Embargoed or late-breaking posters can appear as title-only teasers until their release time.

How do you measure a virtual poster session?

Track poster opens, time spent, author questions, and searches, including searches that returned nothing. Zero-result searches show what attendees wanted that this year's program didn't carry, which is direct input for next year's call for papers.
