MOBL (MObile Biomechanics Laboratory)

Introduction

Mobile Biomechanics Laboratory (MOBL) is an open-access Android-based mobile app for undergraduate biomechanics education. This app includes 10 modules that can demonstrate joint angular kinematics, body segment center of mass, and jumping height. The Android Package (.apk) for installation and the source code developed in Android Studio are available on this website.

Functionability description

This app was originally deployed and tested on a Samsung S7 tablet. The compatibility of this app on other devices is not guaranteed.
Function of each module: Module 1 – 2D pose reconstruction through computer vision; Module 2 & Module 3 – Elbow flexion/extension angle ; Module 4 – trunk lateral bending angle; Module 5 & Module 6 – Shoulder adduction/abduction; Module 7 & Module 8 – Center of mass for male and female (based on anthropometric data); Module 9 – Knee bending angle ; Module 10 – Jumping height. The following figures show the screenshots of each module:
