Introduction

HRI Physio Lib is a library developed by Austin Kothig for researchers in the field of physiological computing. The structure and basic implementation of this library can be found in the image below:

Installing the library:

• Setting up the library requires a couple of steps of installation so please bear with us. Follow these steps in the given order to successfully set up the library:

  • Cloning the repository: navigate to your workspace where you want to install the library and run the following command (It is recommended that you install this library in your ROS2 workspace):
    

      git clone -b devel https://github.com/HBRS-SDP/WS24-physiological-computing.git
    

  • Installing dependencies: as you know our repository uses three external libraries which have been added as submodules in the /deps folder, so we need to clone them first:
    

    cd WS24-physiological-computing/deps/
    

    rm -rf fmt/ && rm -rf labstreaminglayer/ && rm -rf yaml-cpp/
    

    git clone https://github.com/fmtlib/fmt.git
    

    git clone https://github.com/jbeder/yaml-cpp.git
    

    git clone --recurse-submodules https://github.com/sccn/labstreaminglayer.git
    

  • What we have done currently is add the dependencies to our library. One additional step that needs to be done is that we need to build 'labstreaminglayer':

    cd labstreaminglayer/
    

    mkdir build && cd build
    

    cmake ..
    

    make
    

  • You should see a series of percentage statements. If you see no errors then you have successfully installed the dependencies.

  • Then we build HriPhysioLib before our final step. Follow the steps below.

    cd ../../../HriPhysioLib
    

    rm -rf build
    

    mkdir build && cd build
    

    cmake ..
    

    sudo cmake --build . --config Release --target install
    

  • The final step is building our library so navigate back to the home folder i.e. WS24-physiological-computing. Run the following commands:

    cd ../..
    

    mkdir build && cd build
    

    cmake ..
    

    sudo cmake --build . --config Release --target install
    

  • This should result in a successful building of the library. Now you can head over to the /ros2 folder to follow instructions on testing /spectrogram functionality of the library and setting up a ros2 communication node for the library.
