### Growth Trends in Publications and Citations  
Figure 2 illustrates the sharp increase in publications from 2022 onwards, reflecting the rapid growth of interest in the field. Specifically, most documents were published in 2024 (\(n\) = 343, 39.0%), in 2023 (\(n\) = 246, 28.0%), and in 2022 (\(n\) = 119, 13.5%). Additionally, three main time periods can be observed: (1 st) Initial conceptualization years: 2015-2018 in which 25 documents (2.8%) were published; (2 nd) Materialization years: 2019-2021 in which 147 documents (16.7%) were published; and (3 rd) Breakthrough years: 2022-2024 in which 708 documents (80.5%) were published. The outcomes are representative of the advancements in the respective fields that took place in recent years and the increasing interest in these fields. In addition to the annual number of published documents, the

citable years and the mean total citations received per year were also explored. The related data is presented in Table 2.  
The outcomes are in line with the advancements in the respective fields in recent years. When considering the applicability of these technologies and their potential to enrich and transform the educational process, the interest in the topic is expected to continue increasing. Moreover, the citations that the documents published in each year received were also explored as can be seen in Table 2, which depicts the year, the mean total citations per document (MeanTCperDoc), the number of published documents, the mean total citations per year (MeanTCperYear), and the citable years (CitableYears). Based on the outcomes, documents from 2022 had the highest average citations per year (MeanTCperYear = 5.52), reflecting their impact despite being recent. Additionally, documents published in 2021 (MeanTCperYear = 4.06) and in 2019 (MeanTCperYear = 3.11) also presented high mean total citations per year. Nonetheless, given the increasing interest in the field, the average document age (1.36 years), and the citable years of the documents, it is expected that these outcomes will change in the future. This outcome is further validated when considering
