### The Development Insights
#### 3.1.3 Application Deployment in Real Environment  
In order to install the systems and put them into operation in situ, at the museum, the team had to adapt the systems from the laboratory conditions to the real working conditions. Thus, it was necessary to analyze the following aspects:  
* Effective arrangement of equipment in the exhibition, with an impact on the technical elements of connection: network, audio, video signals;
* Design and location of LeapMotion clamping and support systems;
* Configuring the computer systems and adapting their layout so that the communication signals between LeapMotion and the application is not disturbed;
* Designing the necessary elements for the interaction of the visitor with the In Situ Vizualisation Systems ISVS-A, and ISVS-B, within the exhibition.  
After establishing all of the above, the VR system implementation in the exhibition was carried out in stages. A pilot version of ISVS-A equipment was installed for the beginning, with all the elements configured in the complete configuration. For this, we also designed and made a support for the Leap Motion device, adapted to the showcases of the exhibition, so as not to make a discordant note to the museum environment. After installing the ISVS-A component, we installed and configured the ISVS-B system. For this, it was necessary to design and make a support device for the ergonomic arrangement of LeapMotion.  
The custom support for the Leap Motion sensor for the two proposed ISVS-A and ISVS-B system was manufactured using Fused Deposition Modeling (FDM) on a 3D printer. Our main purpose was to enclose the Leap Motion sensor and position the custom support at an optimal height and orientation according to the existing museum exhibition glass display cases and pillar supports. The 3D-printed parts paired with the aluminum profile facilitate a good cable management solution. The main components of each custom support system are illustrated in Figure 3 along with the positioning and orientation of the Leap Motion sensor.  
These configurations have been validated, since the implementation and testing phase in situ, through the direct and effective interaction of the museum visitors. On this occasion, we received immediate feedback with respect to the usability of the system, mostly positive, along with suggestions for improvements. This confirmed that the proposed solution is suitable for the visiting museum public and is an important step forward in highlighting the museum components in a 3D format.  
The system was installed in full configuration after completing these initial steps and validating them in situ.  
The staff of the museum has limited knowledge in the field of operating computing technology; hence, this was a challenge in terms of the daily operation of equipment, hardware and software. This issue has been approached by implementing computer on/off procedures at the computer level, as follows:  
* At the BIOS component, the computer's start time has been set, using PC's BIOS or UEFI;
* Start-up commands have been implemented for launching applications automatically;
* At the end of the working hours, the computing systems set the closing time using the task scheduler mechanisms to set up regular shutdowns.  
Through these mechanisms, we compensate for the low level of knowledge of the museum staff regarding the operation of computer systems and installed applications.
