• Gather a user group of 30 people.
  • The user group should be representative of the population that is intended to use the VR headset.
• Use A/B testing to test the prototypes.
  • The experiment should be designed for different demographics and the findings should be reported systematically in order to make data-driven decisions.
• Measure the readings and compare the data produced with the state-of-the-art measurement systems that are proven to produce high accuracy for heart rate and breathing rate.
  • This is a part of sensor calibration. Sensors have a tendency to degrade over time, causing variations in heart rate and breathing rate readings. They should be corrected using code that can be delivered in over-the-air updates.
• Test compatibility with major VR headset manufacturers.
  • Major VR headset manufacturers are Oculus, HTC, Microsoft, and Samsung. The device should be compatible with the major headsets produced by these manufacturers.
• Test the durability of the sensor by exposing it to various physical conditions such as stress, temperature, and sweat.
  • The device should work across different climates under various temperature and humidity conditions. The device would also be exposed to stress and liquids during normal operations.
