Simulate Step Counter Sensor

The value reported in the onsensorchanged method is always one the fractional part being always zero and the event timestamp is the time when the user s foot hit the ground.

Simulate step counter sensor. Steps steps is a sample application demonstrating the usage of step counter api. Step counter step detector android 4 4 introduced 2 new sensors apis for step tracking. Joaquin iurchuk apr 15 15 at 14 21. Build the circuit explore the sample circuit here in the embedded circuit below by starting the simulation and clicking on the round motion sensor.

You ll have to walk. Starting with windows 10 this sample supports the windows devices sensors pedometer. Obviously you need to execute on a device. Now i want to get the init step value when i start my app.

The step counter sensor provides the number of steps taken by the user since the last reboot while the sensor was activated. You may need to resize the view if the circle is off screen. Step counter is not a real hardware function as it is the gps. This is the code i use at runtime to get the value when it.

The step counter has more latency up to 10 seconds but more accuracy than the step detector sensor. The step detector sensor has very low latency in reporting the steps which is generally within 1 to 2 seconds. Both of these sensors are highly battery optimized and consume very little power. For calculations i need to know the start value.

To test the step counter hold the kit in your hand and rock it back and forth to simulate walking motion as shown in figure 4. Like the android emulator don t let us to simulate the behavior of the step counter sensor we need to execute our application on a real android device. In this sample application history data is used to display a graph of user s steps during current day and up to 7 days in the past. You must declare the activity recognition permission in order for your app to use this sensor on devices running.

I use an eventlistener to get the values while the app is running. Both the sensors are based on a common hardware sensor that internally uses the accelerometer but android still treats them as logically separate sensors. This will activate a highlighted area in front of the sensor with a circle object inside. Do not shake the board vigorously because this motion pattern might be rejected by the motion sensor s internal.

The step detector sensor. Step calculation is the result of dealing with the accelerometers so i think there s no way to simulate them. The step detector sensor triggers an event each time a step is taken by the user. The step counter and step detector sensors are very similar to each other and are used to count the steps.

Upon each user step this sensor delivers an event with a value of 1 0 and a timestamp indicating when the step occurred.
