Discussion - Architecture

Discussion - Design Plugin Management Event Driven Design Interface-based Design Dependency Injection

Discussion - Hardware Wii Remote: ADXL330 accelerometer Broadcom bluetooth device +/- 5g with 10% accuracy Acceleration axes are relative to the device Earth gravity is added to the measurements Motion Plus to improve acceleration reading

Discussion - Acceleration Data Acceleration measured in units of g Exercise patterns are preserved in the acceleration data

Discussion - Motion analysis Algorithm based on published technical articles Mean filter to smooth out the data Adaptive thresholding Dynamic precision Time framing Calories burned calculation

Discussion - Social Networking Share performance with friends Motivate users by showing friends' performance

Discussion - DAL Database Abstraction Layer Persistence of data between exercise sessions Implementation independent method to store data Separates code from data Implemented using SQLite database

Demonstration - Running

Demonstration – Squats

Demonstration – Jumping Jacks
