Sensor_Data_Preprocess-

This is about how to write sensor readings in to a csv in desired manner. The waveSence_data_gen_app folder contains the python script to record examples with the ground truth geneated by LeapMotion along with leapMotion API.

1. Instruction for Running app

note: Insturctions were given for properly setuped LeapMotion SDK V2. For setting ud SDK see the instruction below in Sect. 2. go to the directory waveSence_data_gen_app

1.1 check the serial connection is working properly

if the connection is working correctly running (given in sect 1.3) will give terminal message like,

  opening Serial port
  opened
  Initialized
  Press Enter to quit...

if any serial Execption like,

raise SerialException(msg.errno, "could not open port %s: %s" % (self._port, msg))
serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyUSB#: [Errno 2] No such file or directory: '/dev/ttyUSB#'

occured, check the connection with an external serial monitor with baud rate:115200. if it's working well check the lineNumber:193 serial.Serial('/dev/ttyUSB0',115200,timeout=1) is correctly stating the usb serial device.

1.2 Checking Leapmotion connected and socket is working

for using leapmotion SDK.V2 in Ubuntu after connecting the device manualy run sudo LeapControlPanel for the LeapMotion Control panel.

if a popup says, Leap Daemon is not Running you've to start mannualy Run sudo leapd

When the Leap Daemon is properly working, By clicking the option: Diognistic Visualizer in the Troubleshooting tab of the Leap Motion control panel. This visualizer shows the data from the leapmotion device.

1.3 Running the script

run the script simply by, sudo LD_PRELOAD=./libLeap.so python2.7 WaveSence.py

note: The version of the libLeap.so SDK is from the version (2.3.1+31549). In case of different version use relevent SDK files for Leap.py, Leap.pyc, LeapPython.so, libLeap.so

2.leapMotion SDK

2.1 Installation on Ubuntu

note: LeapMotion SDK supports python 2.7.

Download LeapMotion SDK 2.3.1 from https://developer.leapmotion.com/sdk/v2/
Extract the with tar -xaf LeapDeveloperKit*33747*.tgz
cd LeapDeveloperKit*33747*
sudo dpkg -i Leap*x64.deb

2.1 using SDK with python 2.7 + testing

The Leapmotion SDK 2.3.1-33747 is not properly working on ubuntu. Therefore use the SDK of LeapDeveloperKit 2.3.1-31549 instead if SDK of LeapDeveloperKit 2.3.1-33747.

Download LeapDeveloperKit 2.3.1-31549 form https://developer-archive.leapmotion.com/downloads/external/skeletal-beta/linux?version=2.3.1.31549
tar -xaf LeapDeveloperKit*31549*.tgz
cd LeapDeveloperKit*31549*/LeapSDK
sudo apt-get install swig g++ libpython2.7-dev
cp include/Leap.i include/LeapNEW.i and Edit include/LeapNEW.i and replace every %}} by }}
swig -c++ -python -o /tmp/LeapPython.cpp -interface LeapPython include/LeapNEW.i

testing the SDK

mkdir python2.7_project
cp -a lib/x64/libLeap.so lib/Leap.py samples/Sample.py python2.7_project/
g++ -fPIC -I/usr/include/python2.7 -I./include /tmp/LeapPython.cpp lib/x64/libLeap.so -shared -o python2.7_project/LeapPython.so
cd python2.7_project/
LD_PRELOAD=./libLeap.so python2.7 Sample.py

2.2 using SDK with python 3.5 + testing

steps 5-10 are same as for python 2.7

sudo apt-get install libpython3.5-dev
mkdir python3.5_project
cp -a lib/x64/libLeap.so lib/Leap.py samples/Sample.py python3.5_project/
2to3-3.5 -nw python3.5_project/Sample.py
g++ -fPIC -I/usr/include/python3.5m -I./include /tmp/LeapPython.cpp lib/x64/libLeap.so -shared -o python3.5_project/LeapPython.so
cd python3.5_project/
LD_PRELOAD=./libLeap.so python3.5 Sample.py
