About Wireless IMU
This app sends the measurements from your phone inertial sensors via UDP as CSV (Comma-Separated Values) to a computer in your network.
This turns your phone into a wireless inertial measurement unit (IMU).
The following sensors are supported:
- Accelerometer
- Gyroscope
- Magnetometer
If your phone has not all these sensors, only the available sensor data is transmitted.
Example UDP packet:
890.71558, 3, 0.076, 9.809, 0.565, 4, -0.559, 0.032, -0.134, 5, -21.660,-36.960,-28.140
Timestamp [sec], sensorid, x, y, z, sensorid, x, y, z, sensorid, x, y, z
Sensor id:
3 - Accelerometer (m/s^2)
4 - Gyroscope (rad/s)
5 - Magnetometer (micro-Tesla uT)
You can run this app in the background.
A warning dialog appears, if you are not connected to a WiFi network.
In the example video, the stream is directly processed by a MATLAB script for Kalman Filtering. But it's up to you, what you do with the data.
With the following Python script you can capture the UDP data stream from your phone:
# -------------------------------------------------------
import socket, traceback
host = ''
port = 5555
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
s.bind((host, port))
while 1:
try:
message, address = s.recvfrom(8192)
print message
except (KeyboardInterrupt, SystemExit):
raise
except:
traceback.print_exc()

Awesome app. ssh'd in from my mac and dropped the example code in the home dir. Python newbies don't get caught out by the lack of indentation on the sample code. Fix that at it works a treat. Thank you Jan Kevin

This app turns your android phone (if it has the hardware) into a system for measuring the phones orientation of in three directions. It uses the accelerometers, the gyroscope, and the magnetometers for inputs.

Good app just little slow in my xiaomi phone. Overall very good app

Also, it would be better if the data rates are mentioned with the slow, fast etc. Also the run in background was not working out well for me. I was running my code on matlab and it stops receiving UDP packets as soon as the phone screen shuts off (inspite of enabling run in background). But overall, great app!

The idea is very good, This app can be used to stream raw sensor data to other devices like laptop where you can apply signal processing algorithms. Instead of mentioning faster, fast, medium in the update rate please mention the sensor data rate. Also it would be nice if we can get the sensor data through bluetooth.

Took one minute to install the app, set up the python script on my Raspberry pi, and turn the app on and I had instant streaming stats from my phone sensor on my console. Amazing.

Streaming the rotation matrix available through getRotationMatrix(...) would be nice, too.

This app has good idea, but very ver poor execution. Transmiting UDP packet is not using xml structure as it should. Means that there is very hard to program any universal receiving algorithm. It has a bug when screen is turned to landscape mode, all elements are untouchable and gets overriden. Update rate is set as "fastest", "fast", "medium" and "slow". No frequency settings, and not even information about frequency. This basically does not alows you to use data for correct analysis. There is no filtering, scaling or thresholding and no settings. It is ad-hoc app that is useless for other reason, than author shows on his video.

Saved me from writing the exact same app. I wish it was open sourced so it can be expanded with other sensors, and that the MATLAB code was also available.

Hi, i have install the application, but i dont understand what i have to do to open the data in matlab. Someone can help?
