Behind the scenes, your smartphone utilises advanced technologies like optical sensors, Photoplethysmography and accelerometers to capture and analyse data. By measuring changes in light absorption and reflection or detecting movements and vibrations, it can provide valuable insights into your health status. All of this is made possible through sophisticated algorithms and machine learning techniques that turn raw data into meaningful health information.

Optical sensors, for example, work by emitting light onto your skin and measuring the amount of light that gets absorbed or reflected back. This information is then used to calculate various health parameters, such as heart rate and blood oxygen levels. These sensors are highly accurate and can provide real-time data, allowing you to monitor your health on the go. The front or rear camera can also be used and its this touches health screening capability that is the core strength of Vastmindz.

Accelerometers, on the other hand, detect changes in motion and orientation. They can track your steps, distance travelled, and even determine the intensity of your physical activities. By analysing this data, your smartphone can provide insights into your overall activity levels, helping you make informed decisions about your exercise routine and daily movement patterns.

Machine learning algorithms play a crucial role in contactless health monitoring. They analyse the collected data and identify patterns or anomalies that may indicate potential health issues. For example, by monitoring your heart rate over time, these algorithms can detect irregularities and notify you if there are any concerns. This proactive offensive health approach to health monitoring can be very informative, especially for individuals with pre-existing conditions.

With contactless health monitoring, the power to take control of your health is literally in the palm of your hand. By leveraging the technology already present in your smartphone, you can gather valuable insights about your vital signs, activity levels, and overall well-being. This innovative approach not only simplifies the process of health monitoring but also empowers individuals to make informed decisions and take proactive steps towards a healthier lifestyle.
