Scenario 1 - Tape Measure Comparison
In test scenario 1, simple cubic models were observed
at a 1:1 scale. At each corner of the cube, a mark was
made in the real-world to demarcate where that corner
was perceived to be located. Once all four corners
were observed, the cube was rotated onto it's next
face. This was repeated until all six faces had been
observed. With each corner noted, distances were
subsequently measured to assess the model's
projected dimensions. All 12 lengths of the cube were
observed to assess the scale accuracy of the model
viewer.
In total, three uniquely sized cubes were analyzed: 1) 10cm; 2) 50cm; 3) 1.000m. These cubes
can be seen below in Figures 3, 4, and 5. Once all 12 lengths have been recorded, they can be
averaged to gather an overall sense of the impacts of scale error on the model's dimensions.
Here, scale error was determined by the following formula: Where is d /d ) 00%. e
