Looking at Visualisation in Region

This visualisation shows the proportion of time participants spent looking at visualisations in specific regions (see below figures):

  1. The Wall, defined as a region 0.5m protruding outwards from each of the four virtual walls

  2. The Table, defined as a 0.5m² region in the centre of the room on the virtual table itself

  3. The In-Between, defined as the leftover region sandwiched between the above two regions

The aim of this visualisation was to quantify the areas where participants mostly spent working on their visualisations.

This visualisation only exists for Part B.

While the aim was to measure how much participants used the walls as compared to the tables, we omit discussion about this plot for several reasons:

  1. Time spent looking at a visualisation could either mean actively using it to work, or simply being confused by it and requiring more time to identify insights

  2. Due to the lack of eye-trackers during the study, we use the "gaze" direction of the participant's headset to perform a raycast and determine which object it intersects with, potentially causing inaccuracies when this gaze does not align with participants' actual attention

  3. Most of the time was spent looking at the panels themselves, meaning that these statistics are very dependent on the exact position and orientation of these panels

However, we opt to include it in this supplemental material for posterity and completeness.

We perform some quick data wrangling into the proper format required to plot it using ggplot2 (shown on this page):
