## 4 Experimental Setup and Procedures
### Response Time  
The results for the response time are presented in the same way as for the frame rate. The summary statistics and comparisons can be found in Figure 10 and Tables 5 and 6. The complete datasets are available in the form of a set of scatted plots, linked in Figure 10. Again, the gray color is used for data measured without the proposed components and the black color for data measured with the components. The response time increase in Tables 5 and 6 is computed as the percentage of the average response time without the component, according to (3). \[RT.inc\left(\%\right)=100\%*\left(avg_{r\gamma}-avg_{rn}\right)/avg_{rn} \tag{3}\]  
In (3), \(avg_{rn}\) is the average response time without the component and \(avg_{r\gamma}\) is the average response time with the component. The most significant response time increase was observed with the 6-DoF SMC component (34.15% on average). The response time increase with the ECA component was similar to the frame rate drop (6.08%). Surprisingly, HoloGOM had negligible influence (2.27%). However, the response time on MS HoloLens was significantly higher than on other devices, in all cases. \begin{table}

Table 3: Frame rate summary statistics of the data collected in the E.ECA experiments and frame rate drop computed from the averages. The statistics are given in _frames per second_ and the frame rate drop as a percentage. All values are rounded to two decimal places. “FR.drop” means Frame rate drop, “With” means with the proposed component and “Without” without the component.
