Hello, OpenSim Beta Testers- We are excited for you to try a new software release, called OpenSense. OpenSense is designed to perform kinematic tracking using Inertial Measurement Units (IMUs). If you are able to install the software, run through an example, and offer us your feedback, it would be a great help to us. OpenSense is available as a set of command line tools and through scripting in Matlab and Python. Mac and Windows versions are available. We hope OpenSense will be helpful in your work. To download the software, run through the example, and give us your feedback, please see the instructions in the shared testing doc <https://docs.google.com/spreadsheets/d/1GMKghFjVoHL-gyGU79OKD47ejpmDgZ-j5naAyulAxog/edit?usp=sharing>. If you have any questions or issues, you’re welcome to email us, as well. Please don't hesitate to send any questions or feedback via email as well. Thanks in advance for your help! The OpenSim Team -James
