*3.2. The Virtual Interface*

Virtual reality replaces real sense perceptions by computer-generated ones describing a 3D scene and animations of objects within the scene. The user needs to feel a totally immersive and authentic experience in the VR application. This is achieved by a realistic behavior of the elements, avoiding the latencies between actions and feedback, and creating a high quality 3D reconstruction to transmit to the user the sense of presence [25]. In order to avoid latencies and permit real-time interaction, the VR system requires a powerful dedicated computer [40] (this computer contains the digital twin of the cell also). Moreover, computer graphics and algorithms can be used to improve the rendering process. The high quality 3D reconstruction for the virtual interface can be achieved following the procedure described in [25]:
