    • Indoor navigation using motion sensors? Ian Sheret 3rd December 2009
    • Inertial sensors
    • Inertial sensors Accelerometer senses: • Acceleration • Gravity
    • Inertial sensors Gyro senses: • Rate of rotation
    • Inertial sensors Data fusion to get: • Orientation • Motion tracking?
    • Navigation

    • Motion information Pedometer
    • Motion information Pedometer Foot mounted sensor
    • Environment information
    • Great! Except... • Absolute fix? • Power consumption? • Map matching reliability? • Accuracy? • Value?
    • Ways forward Niche Mainstream applications applications
    • Ways forward... Niche Mainstream applications applications
    • Power management:
    • Power management: Minimum sensors to maintain solution Logging, process on demand?
    • Accuracy:
    • Accuracy: Step Foot counting mounted
    • Accuracy: Step Hybrid Foot counting approaches mounted
    • Gyros and smartphones
    • Opportunities • Where battery doesn’t matter • Highly constrained environments • Crowd-sourcing
