Table 6: Statistical Analysis of Positional Error (m)
Table 7 below assesses the positional error at each incremental distance away from the anchor
point. Clearly, in both cases, the error increases as the user walks further away from the
model's anchor. However, when utilizing WLT, positional error of the perceived hologram
location is on average 3x less than without WLT. Figure 8 visually depicts the positional error of
the model as the user walks further away from the anchor point.

Table 7: Positional Error by Distance (m)
By observing the chart below, it is clear that not only does the addition of WLT decrease the
perceived drift error of the model, but it is relatively consistent over distance, indicating a more
persistent model viewing experience for the user.
