1 Introduction
Xsens has released the 2
nd
generation of Xsens DOT hardware (hereinafter as v2). The
hardware upgrade includes specification improvements as well as user experience
optimizations. The Xsens DOT sensor and charger have been upgraded as a drop and
replaceable hardware to the existing first generation. Refer to the
Product Change
Notification for the details about this upgrade. This document is applicable to v2 with the
latest firmware (v2.0.0) and software (v2021.0) versions. Refer to this link for the archived
user manual for v1 hardware.
Xsens DOT is a wearable sensor development platform which features sensor incorporating
3D accelerometer, gyroscope and magnetometer to provide an accurate 3D orientation.
The embedded processor in the sensor handles sampling, calibration, strap-down
integration of inertial data and the Xsens Kalman Filter core (XKFCore) algorithm for sensor
fusion. With wireless data transmission through Bluetooth 5.0, Xsens DOT can provide real-
time 3D orientation as well as calibrated 3D linear acceleration, angular velocity and (earth)
magnetic field data to a receiving device.
Xsens DOT is the start of a new Xsens product line bringing Xsens sensor solutions to
mobile device platforms. With simple-to-use Software-Development-Kit (SDK) and
comprehensive documentation, system integrators can easily develop their wearable
applications.
The Bluetooth Low Energy (BLE) data transmission, lightweight form factor and IP68 water-
proof rating widen the application areas of Xsens DOT, making it easy and durable to use
in various scenarios. Using different combinations of 5 sensors, it’s flexible to apply Xsens
DOT to customized measurement cases.
Fields of use:
1. Health and rehabilitation
2. Sports and exercise science
3. Ergonomics
