how to send accelerometer data from phone to desktop?

in Android Processing • 2 years ago

Hi all,

i want to use the output of the accelerometer of my HTC in a processing sketch on my desktop (i want to use the values as midi messages).

First I thought of sending the values through BlueTooth. It turns out that i do not have a bluetooth device on my computer....

any ideas on how i can send these values at high speed? Maybe over the wifi network?

Any help greatly appreciated!

Try this:

note, you have to add oscp5 in the Sketch > Add File

//-----------------------------------------------------------------------------------------
// Imports required for sensor usage:
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorManager;
import android.hardware.SensorEventListener;
// OSCP5
//import oscP5.*;
//import netP5.*;
//-----------------------------------------------------------------------------------------
// Screen Data:
float sw, sh;
// Font Data:
String[] fontList;
PFont androidFont;
int text_size = 45;
// Setup variables for the SensorManager, the SensorEventListeners,
// the Sensors, and the arrays to hold the resultant sensor values:
SensorManager mSensorManager;
MySensorEventListener accSensorEventListener;
Sensor acc_sensor;
float[] acc_values;
// OSC
OscP5 oscP5;
NetAddress myRemoteLocation;
//-----------------------------------------------------------------------------------------
void setup() {
size(screenWidth, screenHeight, A2D);
sw = screenWidth; // 480.0 on Nexus One
sh = screenHeight; // 800.0 on Nexus One
// Set this so the sketch won't reset as the phone is rotated:
orientation(PORTRAIT);
// Setup Fonts:
fontList = PFont.list();
androidFont = createFont(fontList[0], text_size, true);
textFont(androidFont);
// OSCP5
oscP5 = new OscP5(this,12000);
myRemoteLocation = new NetAddress("192.168.2.103",12000);
}
//-----------------------------------------------------------------------------------------
void draw() {
fill(0);
rect(0,0,sw,sh);
fill(255);
noStroke();
// Remap our Accelerometer Values to Screen Values
float Azimuth = acc_values[0];
float mapX = map(Azimuth, 10, -10, 0, 480);
float Pitch = acc_values[1];
float mapY = map(Pitch, -10, 10, 0, 800);
// Draw our X and Y depending upon the Accelerometer
if (acc_values != null) {
text(" X " + acc_values[0], mapX - text_size, sh/2, 80, 80);
text(" Y " + acc_values[1], sw/2 - text_size, mapY, 80, 80);
oscP5.send("/android",new Object[] {new Float(acc_values[0]), new Float(acc_values[1]), new Float(acc_values[2])}, myRemoteLocation);
}
else {
text("Accelerometer: null", 8, 20);
}
}
//-----------------------------------------------------------------------------------------
// Override the parent (super) Activity class:
void onResume() {
super.onResume();
println("RESUMED! (Sketch Entered...)");
// Build our SensorManager:
mSensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
// Build a SensorEventListener for each type of sensor:
accSensorEventListener = new MySensorEventListener();
// Get each of our Sensors:
acc_sensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
// Register the SensorEventListeners with their Sensor, and their SensorManager:
mSensorManager.registerListener(accSensorEventListener, acc_sensor, SensorManager.SENSOR_DELAY_GAME);
}
void onPause() {
// Unregister all of our SensorEventListeners upon exit:
mSensorManager.unregisterListener(accSensorEventListener);
println("PAUSED! (Sketch Exited...)");
super.onPause();
}
//-----------------------------------------------------------------------------------------
// Setup our SensorEventListener
class MySensorEventListener implements SensorEventListener {
void onSensorChanged(SensorEvent event) {
int eventType = event.sensor.getType();
if(eventType == Sensor.TYPE_ACCELEROMETER) {
acc_values = event.values;
}
}
void onAccuracyChanged(Sensor sensor, int accuracy) {
// do nothin...
}
}

Thanks for the reply,

I did not work on this for a while, will start up again.

The ketai motion library seems to do the job for me. but thanks anyway!

I have to make almost same application, but via bluetooth!

How can i do that?

My values, must be sent to my mac and then processed by labview!
