Overview
COVID AR is a simulation of mouth droplets and how they can spread COVID-19, depending on the amount of people and time, the activity, masks, and ventilation.
Pressing the Breathe, Talk, or Shout button shows a burst of two Unity particles to simulate droplets coming from the mouth, one falls to the floor like large droplets and the other floats like small droplets (a.k.a. aerosols). The particle velocity depends on the intensity of the activity, slowest for breathing to fastest for shouting.
The Wind toggle adds a gust of wind to show that with proper ventilation, droplets disperse and have less of a chance of getting into your body or someone else’s.
Turning on the Crowd toggle places three humanoid models around you. Then, pressing the Breathe, Talk, or Shout button activates the animation and Unity particles attached to the humanoids, simulating people nearby releasing droplets.
The Mask toggles (My Mask and Crowd Masks) place opaque cubes in front of the Unity Particles. The cubes have colliders that prevent most particles from moving farther, simulating how a mask can block your droplets while preventing other’s droplets from entering your mouth or nose.
