Description: This is the repository for CS281A Spring at Berkeley.
We focus on activity recognition problem on commercial mobile platforms including Android phones, Google Glass and Pebble Smartwatch. Because of their different positions on human body, their performances would differ; and this project aims to investigate 1) which device is better for which activity, 2) the quantitative differnece. We describe the whole process of system implementation, data collection, feature extraction and activity recognition, and present our findings of the performance for each device.
