abstract: Motion Control For Remote Archaeological Presentations

My abstract for 21 May talk at the Digital Heritage 3D representation conference at Moesgaard Museum Aarhus Denmark

Title: Motion Control For Remote Archaeological Presentations

Displaying research data between archaeologists or to the general public is usually through linear presentations, timed or stepped through by a presenter. Through the use of motion tracking and gestures being tracked by a camera sensor, presenters can provide a more engaging experience to their audience, as they won’t have to rely on prepared static media, timing, or a mouse. While low-cost camera tracking allow participants to have their gestures, movements, and group behaviour fed into the virtual environment, either directly (the presenter is streamed) or indirectly (a character represents the presenter).

Using an 8 metre wide curved display (Figure 1) that can feature several on-screen panes at once, the audience can view the presenter next to a digital environment, with slides or movies or other presentation media triggered by the presenter’s hand or arm pointing at specific objects (Figure 2). An alternative is for a character inside the digital environment mirroring the body gestures of the presenter; where the virtual character points will trigger slides or other media that relates to the highlighted 3D objects in the digital scene.

Does visualisation ever provide new insight in the humanities?

The Dean of Research at my Faculty of Humanities asked this yesterday.I have decided this could become a future book project, answering that question, I mean.

To explain this to my students I usually refer to the best historical examples. Epidemiology, for instance, would not be the same without thematic mapping, as maps let you take a peek behind the data, see what the numbers hide. The classic is Snow’s Cholera map, obviously, which I praise here http://blog.visual.ly/infographi… but there are many others. I’d recommend two books about data maps: “Cartographies of Disease” http://www.amazon.com/Cartograph… and “Early Thematic Mapping in the History of Cartography”http://www.amazon.com/Early-Them… which revisits some well known names, such as Charles Joseph Minard, and casts lights on others that are not so well known.

here’s an “Aha!” moment sometimes. Even on the most obvious things. Take Matthew Bloch [and Shan Carter and Alan McLean]’s census maps.

I’m just seeing what I basically know: New York neighborhoods are segregated. But I felt it in a way I never had before. You can feel a good data visualization.

One thing we did was take a very simple unemployment chart — your most basic visualization — and we let people choose a Democrat or Republican interpretation of the data.

You can literally see the visualization change based on whose point of view was highlighted. It would be silly to interpret any data viz as truth. They are interpretations of truth.
