MATLAB Mobile calculates orientation using the Android device's built-in sensors, specifically the accelerometer and magnetometer. These sensors provide raw data that MATLAB Mobile processes to determine the device's orientation in space. The rotation is measured using three angular quantities – Pitch (around X axis), Roll (around Y axis), and Azimuth (around Z axis). You can read more about it on this MathWorks documentation page from the latest release as of now, R2024b: https://www.mathworks.com/help/simulink/supportpkg/android_ref/orientation.html
Do note that using this feature requires the Simulink Support Package for Android Devices add-on: https://www.mathworks.com/hardware-support/android-programming-simulink.html
Using these calculations, MATLAB Mobile can provide a real-time orientation of the device, which can be utilized in various applications like navigation, gaming, and augmented reality.

MATLAB Mobile determines orientation by using the device's (Android or iOS) built-in sensors, specifically the accelerometer and magnetometer. These sensors provide raw data that MATLAB Mobile processes to determine the device's orientation in space. The orientation is typically expressed in terms of three angles: Pitch, Roll, and Azimuth.
To directly access this orientation data, you can use the orientlog function in MATLAB. For more details, visit the MathWorks documentation.
This approach provides real-time orientation data, allowing you to effectively explore the device's position in space.
Tip: To use this function for accessing mobile sensors from your desktop or laptop, you'll need to install an add-on. Depending on your device, you can choose the MATLAB Support Package for Apple iOS Sensors or the MATLAB Support Package for Android Sensors.
