2D and 3D simulation.

Left: 3D simulation. The user wears the HMD and is immersed into a virtual environment showing a virtual representation of the manikin. Thanks to an HTC controller that tracks the neonatal island position, the virtual and real manikins are overlapped to each other and move accordingly. Right: 2D simulation. The user can physically interact with the manikin and receives feedback from a User Interface (UI) displayed on a computer screen. Sensors in the manikin and the face mask sends data to the immersive VR application or the GUI to monitor the user performance in real time. UI description: Top left: the UI provides feedback about the manikin’s head position. Top right: mask position; simple controls have been implemented to manage the colour code; if the area turns red, completely incorrect positioning; if the mask turns yellow, partially incorrect positioning; if the area turns green, correct positioning. Bottom left: Ventilation rhythm If the sensor in the face mask is pressed (inhalation), the lungs in the UI are filled, during exhalation phase (sensor not touched), they are empty. Bottom right: chest compressions are shown on a line chart according to the data measured by the infrared sensor.
