HAR using sensor data

I am interested in the example Human Activity recognition using sensor data that I have found on MATLAB Online. The example is given in three separate livescript files.

The HumanActivityData data set contains over 380000 observations of five different physical human activities captured at a frequency of 10 Hz. Each observation includes x, y, and z acceleration data measured by a smartphone accelerometer sensor.

Different techniques are studied to improve model accuracy with different classification methods and compare metrics such as accuracy and training time.

I'd like to show this application in a class, and I'd be very grateful if I could have some documentation on the data to tell the students.

I'd appreciate very much also documentation on the example.

Which data would thab be, pray tell?

It is HumanActivityData dataset that contains over 380000 observations of five different physical human activities captured at a frequency of 10 Hz. Each observation includes x, y, and z acceleration data.

I have found the dataset on MATLAB Online at /MATLAB Drive/Examples/Marketing/machine-learning-examples-humanactivitypart1-mlx

I'd like to have documentation on the dataset (and hopefully on the implementation) so that I can illustrate the example in class.

Further digging uncovered the link to the UCI web site that is still active...

It has link to a published paper

Thanks a lot!
