Activity classification is based on more advanced signal processing, by extracting some specific features out of the 3-axis accelerometer signal and classifying the *accelerometer* pattern into different categories (walking, running, etc). Activity classifier is available on a subset of activities (resting, walking, running, biking, rowing and other). Please use classifier as per table and note that you will not see all the bnumbers from the list in the App/CSV file/SDK as not all of them could be identified by the algorithm yet.
