Key Design Decisions
The key design decisions that defined the way our experience felt to a user were how we chose to display data, source comparison data, highlight objects, and thematically tie together our experience.
Displaying user data
The Tobii Nano Pro allowed us to get information on the X/Y coordinates of a person’s gaze path, with longer looks leading to a higher concentration of gaze points in a particular area. Capturing multiple points per minute, we had a wealth of data to work with, so a key challenge was how we would display this information in a way that was easy to understand and delightful for the user.
We ended up deciding to show a user’s gaze path for 30 seconds first, or collection of points in sequential order from when they started looking at a painting to 30 seconds later, connected by a line. Users liked this format because they were able to directly recall what they were thinking when their eyes shifted from one location to another.
We would compare their gaze path to that of a curator so that they could see what areas they missed, or brag to friends if their way of looking at a painting was similar to a professional’s.Afterwards, we would show their heat map, and compare that to a curator’s as well. A heat map was created by measuring the duration of gaze in a particular area (measuring the amount of gaze points condensed in the area), and creating a map of high and low gaze points throughout the painting. We ended up going in this direction because users really analyzing what they focused the most on.
Sourcing Curator DataSometimes the ideal solution is too costly or expensive time-wise, and it’s important to do a design work-around to still achieve the same result. Because we wanted to compare user data with curator data, we needed to have documented curator data. Getting this data was costly because we were not in the same location, and could only fly out to St. Petersburg once for installation. We got scrappy, and self-generated curator gaze paths based on what we knew about the painting. Having had spent so much time interviewing curators, we had an understanding of how they would view a painting, and constructed gaze paths using our own eyes.
Highlighting ObjectsTo teach users about different parts of the painting, we needed to draw their attention to the element we were discussing. This led us to consider how we wanted to highlight an object of interest. From blurring the background to highlighting an object’s exterior contour, we tried out different methods until we settled on pointing an arrow at the object, and having the arrow’s path follow that of a curator’s gaze path.
Visual Themes
Because our experience would be publicly showcased, we wanted it to have a cohesive visual feel for its users. It was important to use that it sparked delight but also was non-distracting from the paintings, we explored many different potential options before settling on the final minimalistic black theme.
