## 5 Evaluation
### NASA TLX (Post-Experiment)  
The application of NASA-TLX (post-experiment) took place immediately after the activity of reading and interpreting the Augmented TD. This evaluation allowed for a subjective analysis of the degree of impact of the tool in the scenography environment. The data extracted from the method are described in Table 1. The evaluation of the tool's usage encompassed both scenography companies, compiling the data jointly to obtain a result that reflects the participants' performance in using the Augmented TD, regardless of the company. This aims to visualize the effectiveness of the mediation tool at the sector level, not just the organizational level. The high production demand within the scenography settings, driven by tight production deadlines, contributed to the inconsistent availability of some participants. In other words, the evaluation of workload conducted with the Augmented TD (NASA-TLX post-experiment) was also performed with new individuals. The data from the table above are illustrated in Figure 13. In the top row, it can be observed that the weighted index of participants was 45.8 and 48 points in the evaluation of workload using conventional TDs (NASA-TLX pre-experiment). This is higher than the index recorded in the second test (NASA-TLX post-experiment), which was 20.3 points. This corresponds to a significant average reduction of 56.7% in the overall workload related to TD reading in scenography. \begin{table}

Table 1: Evaluation of NASA-TLX workload (post-experiment) in leaders and employees of scenographies. Despite this second NASA-TLX test not having the same participants, it was possible to analyze the data in this format. Figure 13 illustrates some of these data. The figure shows the data from the Production and Operations Manager of Ceno Mais and the Executive Director of Baluarte Group. The weighted ratings show an average reduction of 37.9% (from 58 to 36) in the participant's workload index, primarily impacting effort, frustration, and the fact that the participants are not in the same category. Figure 13: NASA-TLX (pre-experiment), [PERSON] and Baluarte; NASA-TLX post-experiment ([PERSON] and Baluarte). and temporal demands. On the other hand, the analysis of individual data showed that the new tool increased mental demand significantly, with a lesser impact on performance demand. This aligns with some characteristics predicted in the literature [16], such as moderating factors of AR expertise that can increase cognitive processes, in this case, the mental demand for using the tool.
