How to run a human spectrogram map

human spectrogram mapWhenever I open a meeting I run a human spectrogram map, allowing participants to quickly discover everyone at the meeting who lives (or works) near them. This is one of the most useful things you can do for a group of people who don’t know each other — and it only takes a few minutes!

A basic human spectrogram map

The resources for a human spectrogram map are simple: a projected map of the geographic region where the majority of participants live, with the current location marked, and enough clear space in the room for participants to move around easily.

To run a map spectrogram, stand in your room’s clear space in a spot facing the map, positioned in the room so that you mirror the position of the venue marker on the map. If you are using the spectrogram to show where people live or work, say something like the following:

“Let’s find out where everyone [lives/works]. OK, this direction [point, usually from where you’re standing toward the projected map] is north, and where I’m standing in the room is [the location of the conference], so if you [live/work] around the corner you’ll stand right next to me. Here’s a map of [the conference region/country/continent] for the geographically challenged, like me. Please move to stand where you [live/work]. You’ll need to talk to each other!”

If there are major cities or landmarks nearby, it’s helpful to point to where they would be represented in the room. On a map of a country, like the U.S.A. map above, I point to the places in the room representing regions: e.g., “There’s New England, where I’m from, Florida’s over there, Minneapolis is in that direction, and California’s to my left.”

Wait while people determine where to stand. Once most people seem to have found their right location, ask them to introduce themselves to each other and give them some time to do so.

It’s hard to stop the hubbub of conversation that results! Notice anyone who’s standing at the edges of the room (i.e. they live/work outside the map region), ask them where they’re from, and announce it to the group. Also notice anyone who’s standing alone and encourage them to meet their nearest neighbors.

Map variations

You can adapt this simple spectrogram to specific needs. If you’re exploring how much participants have moved over, say, the last twenty years, you can do a state-change spectrogram by asking people, at your signal, to move to where they lived twenty years ago. Or you can ask them to walk continually between where they work and where they live.

I once ran a map human spectrogram in Abu Dhabi, where most of the workers are not local. When I projected the original map of the United Arab Emirates, we found that everyone at the meeting was living in either Abu Dhabi or Dubai. But when I asked people to move to their country of origin, everyone moved to different places at the edges of the room. I went round and asked the different groups to announce their countries of origin, and then gave them time to discover their birthplace companions.

New ideas I haven’t tried (yet)

One thing I’d love to try at a large venue is to project the map on the floor. Wouldn’t that be great! Perhaps some of the A/V experts who read this blog can share how feasible this is?

Another idea would be to run a map spectrogram in a large room during a social, and set up state and/or city tables with pole signs where food and beverages are served. You could use the attendee list geographic data to predetermine the numbers of tables, their sizes and locations.

Conclusion

Whenever possible, make sure you include a human spectrogram map early in your meetings. Your attendees will thank you!
