The person can use\ndeep breathing to create these and in turn relax.\n\nThe high precision bioamplifier [Attys](https://www.attys.tech) is\nused to record the ECG in realtime and the Oculus then detects\nwith high precision the heartbeats and calculates the heartrate.\n\nThe app is written in C++ using the openXR / openGL framework\nwhich allows realtime processing and animation of the ECG\nin the headset.\n\n## Prerequisites\n\n1. Change into `AttysHRV/app/src/main/cpp` and clone the IIR filter library and the spline interpolation library:\n\n```\ngit clone https://github.com/berndporr/iir1.git\ngit clone https://github.com/berndporr/cxx-spline.git\n```\n\n2. Download the [Oculus openXR API](https://developer.oculus.com/downloads/package/oculus-openxr-mobile-sdk/), create\n   a subdirectory `ovr_openxr_mobile_sdk` and unzip the contents of the openxr SDK into it.\n\n   Edit `app/src/main/cpp/CMakeLists.txt` and point it to the openXR API:\n  `set(OCULUS_OPENXR_MOBILE_SDK /home/yourname/ovr_openxr_mobile_sdk)`\n\n3. Clone [AttysComm](https://github.com/glasgowneuro/AttysComm) and modify `app/build.gradle` so that it points\n   to AttysComm.\n\n## Compile \u0026 run\n\nStart Android Studio, open AttysHRV and click `run`.\n\n## How to use the app\n\nhttps://www.attys.tech/attyshrv/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fglasgowneuro%2Fattyshrv","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fglasgowneuro%2Fattyshrv","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fglasgowneuro%2Fattyshrv/lists"}
