android-pedometer's Introduction
android-pedometer
Requirements:
Count steps in 2 orthogonal directions
Button to reset steps
Calibration
Low error rate
Components/Checklist:
Pedometer: steps taken - Pierre
Orientation: direction of steps
Get acc + mag sensor combo working together to produce an azimuth - Tian
Calculate the North and East components of each step taken - Tian
Smooth the sensors - Pierre
Map - Tian
Reset button - Nelson
Calibration button/popup - disables steps - Nelson
(Optional) Pause step counting when a high angular velocity is detected to reduce false postives.
Implementation:
Step detection code will be carried over from previous lab
Each time step is updated a method will be called to update the North and East components of the step, from sin(theta) and cos(theta), theta value obtained from orientation sensor
Buttons:
reset: changes all steps to 0
calibration: disables step registering, show popup dialog to rotate phone
