PRECISION
Easyfit HR can sense every single movement your body makes through two sensors that work in unison to
correctly read all your movements.
The tracking we offer with this product is as good as 3D tracking for all intents and purposes and works
using a complex system. We will try to explain the concept in a clear, concise manner so you can understand
how all your movements are essentially converted into numbers that are easy to view and available in real
time.
What is 3D tracking?
3D tracking is a feature that uses inertial sensors to collect data on your body's movement. An inertial sensor
records the state of your body and its relative changes in case of movement, for example, uniform rectilinear
motion or a rotational movement around an axis. The key here is rotational movement around an axis,
because the concept of 3D tracking revolves precisely around axial dynamics. Indeed, three-dimensionality
is built around the three axes around which our body moves in our surrounding space.
Easyfit HR – User manual
This is a simplified diagram of an inertial sensor. The
ball's weight makes it move along three axes
depending on how the sensor is moved. This is the
basic mechanism of the sensor inside your Easyfit HR:
it's easy to understand, therefore, how every
movement of your body can easily be detected.
