sensor

I find it very hard to get any consolidating information about which Android phones do have a gyroscope, or if there are Android phones with this sensor at all. I read about some (especially Samsung) phone models that have at least a 6-axis accelerometer, but I also read that this is different to a real gyroscope. So my questions are: Which Android phones do have a gyroscope? (Should be usable with the Android API's Sensor.TYPE_GYROSCOPE which is available since API 3) Which Android phones do have a 6-axis accelerometer? Any references like links, specs etc. are greatly appreciated and of

There are 2 ways to get the 3 rotation values (azimuth, pitch, roll). One is registering a listener of a type TYPE_ORIENTATION. It's the easiest way and I get a correct range of values from every rotation as the documentation says: azimuth: [0, 359] pitch: [-180, 180] roll: [-90, 90] The other one, the most precise and complex to understand the first time you see it. Android recommends it, so I want to use it, but I get different values. azimuth: [-180, 180]. -180/180 is S, 0 i N, 90 E and -90 W. pitch: [-90, 90]. 90 is 90, -90 is -90, 0 is 0 but -180/180 (lying with the screen downwards) is 0

( edit: I added the best working approach in my augmented reality framework and now also take the gyroscope into account which makes it much more stable again: DroidAR framework ) I have written a TestSuite to find out how to calculate the rotation angles from the data you get in SensorEventListener.onSensorChanged() . I really hope you can complete my solution to help people who will have the same problems like me. Here is the code, I think you will understand it after reading it. Feel free to change it, the main idea was to implement several methods to send the orientation angles to the

[EDIT] The answer by @Claudio gives me a really good tip on how to filter out outliers. I do want to start using a Kalman filter on my data though. So I changed the example data below so that it has subtle variation noise which are not so extreme (which I see a lot as well). If anybody else could give me some direction on how to use PyKalman on my data that would be great. [/EDIT] For a robotics project I'm trying to track a kite in the air with a camera. I'm programming in Python and I pasted some noisy location results below (every item also has a datetime object included, but I left them

I need suggestion about how to detect the amount of movement of an android device. Suppose I have put the phone on a table or bed and then if somebody taps the table or sits or laydown on the bed then I want to detect the movement of the android device. Actually I know that android has motion sensors APIs but I don't know which sensor to use and what sensor type is best for this type of movement detection. I would be glad if someone can share some basic demo code. Definitely work with the accelerometer: // Start with some variables private SensorManager sensorMan; private Sensor accelerometer;

I'm trying to get both accelerometer and orientation data. Currently, I created an AccelerometerManager and OrientationManager. They both do the same thing; implement SensorEventListener and retrieve data from values[] in onSensorChanged() listeners. Is there an easier way to do this? It seems like having 2 handlers with duplicate code is uneccessary. Is there a way to access a values[] array with the combined accelerometer and orientation data together? Because of the 2 handlers, I'm also having to do this: orientationManager = new OrientationManager(this); orientationSensorManager =
