This signage serves to guide visitors in identifying interactive buttons and understanding that it is necessary to stand on them to activate them. This modification was prompted by feedback from III CM Malaga. Figure 13 provides a visual comparison between the interaction buttons featured in the alpha version showcased in the III CM Malaga (see Figure 13a) and the subsequent \begin{table}
\begin{tabular}{c c c} \hline \hline
**Number** & **Type** & **Description of the Question** \\ \hline (1) & Quantitative & How would you rate your ability to navigate and interact in the Spatial.io metaverse? \\ \hline (2) & Quantitative & What did you think of the functionality of the overlay maps (geographic of heights, temperatures, meteorite fallout) activatable by stepping on buttons with the avatar? \\ \hline (3) & Quantitative & How would you rate the animation of the Space X spacecraft and Perseverance? \\ \hline (4) & Quantitative & How would you rate your experience of socializing in space with other visitors and the guide assisting in the visit? \\ \hline (5) & Qualitative & Were you able to activate the interactive 3D Mars maps without external help? \\ \hline (6) & Qualitative & Do you have any ideas or comments on how to improve or apply this experience? \\ \hline \hline \end{tabular}

Notably, all buttons have been redesigned and now require stepping on them, or standing on them, to initiate an action. This transformation was implemented with the goal of enhancing user comprehension and simplifying interaction within the virtual environment. These refinements are aimed at improving overall user experience and promoting seamless navigation through the immersive space. Future testing will expand user diversity and using VR headsets alongside other devices to ensure a comprehensive and interactive visitor experience. The Spatial.io platform's capabilities for audiovisual interaction and dynamic movement will continue to play a crucial role in these developments. Qualitative data highlighted that visitors engaged more with interactive elements than static displays, indicating the value of dynamic content in maintaining visitor interest. Feedback post-visit was overwhelmingly positive, with many users expressing a desire to return to the virtual exhibition, suggesting a successful engagement and educational outcome. It is important to recognize that approaches such as the one presented in this work can bring significant benefits to the museum industry, and they also raise various ethical

Technological dependence and the excessive use of devices can create a bubble of informational relationships, which calls for a critical reflection on the potential risks embedded within this densely woven information network [57]. Moreover, privacy and data protection are critical ethical concerns when implementing VR in museums. The collection and utilization of personal data can compromise user privacy and pose significant risks to information security [58]. Additionally, issues of accessibility and inclusion are paramount; the technology must be inclusive and accessible to all individuals, including those with disabilities and those who do not have access to high-end devices [59]. Furthermore, the authenticity and integrity of cultural heritage must be carefully considered. It is essential that VR technology respects the authenticity and integrity of cultural artifacts and avoids any distortion or manipulation of historical information [57]. Lastly, the sustainability and environmental impact of VR technologies should not be overlooked. These technologies must be designed and employed in a manner that minimizes environmental degradation and promotes long-term sustainability [58].
