Description

OpenIMU aims to provide an open source and free generic data importer, viewer, manager, processor and exporter for Inertial Measurement Units (IMU) and actimetry data. By using a common sensor data format and structure, data from different sources can be imported and managed in the software. This software was developped with support from INTER.

Features

Current features

• Common file format (SQLite) managed by OpenIMU, but that can also be opened from other software

• Import recorded data from sensors:

  • Actigraph GTX3 series
  • OpenIMU-MiniLogger
  • AppleWatch SensorLogger (Custom research app for data collection)

• Transfer data directly from sensors:

  • AppleWatch SensorLogger (Custom research app for data collection)

• Data organization

  • By participants groups
  • By participants
  • By recordsets
  • By results

• Data viewing

  • Temporal display of recordsets to quickly see when data was recorded
  • Sensor graph view plotting with zoom functions
  • GPS viewer for GPS data

• Data processing

  • Processing module, currently supporting:
    
    • Freedson Activity Algorithm (Freedson PS1, Melanson E, Sirard J., Calibration of the Computer Science and Applications, Inc. accelerometer., Med Sci Sports Exerc. 1998 May;30(5):777-81)
  • Evenson Activity Alogirhtm (Kelly R. Evenson, Diane J. Catellier, Karminder Gill, Kristin S. Ondrak & Robert G. McMurray (2008) Calibration of two objective measures of physical activity for children, Journal of Sports Sciences, 26:14, 1557-1565, DOI: 10.1080/02640410802334196 )
  • Processed results viewer

• Data exporter

  • CSV format
  • Matlab format
  • Data export selector

• Available in French and English, and as Windows and Mac OS apps.

Planned features

• Data splitting into sub-recordsets (by time, by day, manually)

• More data processing modules

Getting Started for Developers

Please follow those steps to setup your development environment.

Requirements

1. Make sure you have a valid compiler installed:

   1. Linux : gcc/g++
   2. Mac : LLVM through XCode
   3. Windows: Visual Studio C++ 2017

2. Install CMake

3. Install Qt + QtCreator

   1. Install the latest Desktop distribution fitting your compiling environment (will not be needed in the future)

4. Install MiniConda3

5. Install PyCharm Community Edition

Step 1 : Open the root CMakeLists.txt in QtCreator

1. Opening the root CMakeLists.txt will allow to create and build the project
   1. Build the project using the "python-all" target, it will automatically generate the Python environment in env/python-3.10, PySide6 UI and RCC files.
   2. All python dependencies will be automatically downloaded
   3. Once the project is built, you will not need QtCreator until you change or add a resource file or a QtDesigner ui file.
   4. If you change or add ui or resources files, you need to rebuild the project from QtCreator.

Step 2 : Create a PyCharm project

1. Using PyCharm, opening the directory "{PROJECT_ROOT}/python"
   1. Select the existing Python 3.10 environment in "{PROJECT_ROOT}/python/env/python-3.10" in the app menu: PyCharm->Preferences->Project:python->Project Interpreter

Step 3 : Run the application

1. Run the OpenIMUApp.py application from PyCharm

2. Edit the code as you would normally do in a python program.

3. Run tests in the tests directory

Notes

1. In a near future, we hope to have everything in the QtCreator IDE. Stay tuned!

Enjoy!
