Zoom Into the Human Bloodstream: Annotated Poster

Overview

Description

This illustration shows the circulatory system across 10 orders of magnitude. Using the conventions of visual perspective the image travels in one continuous “landscape” from the human scale at the top to the atomic scale in the foreground. Placing objects from the circulatory system in one frame clarifies the connections between components, highlighting the system’s reliance on structures at very different scales. This illustration won the NSF/Science Magazine Visualization Challenge in 2008.

This illustration is available as a poster with annotated text, a banner, a poster without annotations or a graphic file, and also appears on the "Everything is Made of Atoms" Poster with other parallel zooms into a butterfly wing and a computer chip.

Illustrations – Human Bloodstream and Butterfly

Major Findings

    •    Most visitors thought the two illustrations showed how one thing is made of other things.  Although, when asked what they thought everything was made of, slightly less than half said molecules or atoms.  This may be because about half (8/14) of the visitors recognized the depiction of the atoms used in the illustrations.
•    Most visitors recognized the macroscale objects in the human illustration.  Slightly fewer were able to identify the butterfly as a butterfly.  In both cases, visitors were much less familiar with the micro and nanoscale objects and recognized few of them, particularly for the butterfly illustration.
•    In general, a majority of the visitors saw the illustrations as a zoom.  There were a few points of confusion, however:
      −    Some (5/14) visitors did not realize that the small balls in the background were the same as the big balls in the foreground, even though they all represent atoms of about the same size.
      −     Some visitors (5/14) were unsure if objects on the same level (e.g., red blood cells and platelet) were in the same size scale. 
•    We could not determine if visitors wanted labels to identify the objects in the illustrations; half said yes, and the other said no.

Recommendations for practice

•    If only one poster can be display, consider using the illustration that zooms into the human bloodstream since visitors seem more familiar with the objects depicted.
