JavaScript Eventing

• DeviceMotion
• DeviceOrientation

DeviceMotion

• Acceleration
• AccelerationIncludingGravity
• Measured in meters per second squared (m/s^2)
• The x-axis runs side-to-side
• The y-axis runs front-to-back
• The z-axis comes straight up out of the mobile phone screen

DeviceOrientation

• Measured in degrees 0 - 360
• Lay phone flat with top pointing away from you
• Point top of phone directly north
• The x-axis (alpha) increases as you rotate to the right
• The y-axis (beta) increases as you tilt up towards you
• The z-axis (gamma) increases as you tilt side to side

Why use DeviceMotion

• More generally supported

Why use DeviceOrientation

• Doesn't need calibration
• Data returned is more useful
• Can be used to "understand" how device is being held
