OpenSim Workshop

• Gain more insight in the Opensim workflow

using your own motion capture data:– Learn the underlying theory, best practices, and trouble

shooting tips for IK, RRA and CMC through hands-on practice

– Learn techniques for data management OpenSim in your own research

– Become confident in your data workflow

• Achieve your project goals and share your results

• Advance your research!

Objectives for the Workshop

OpenSim Workshop

• OpenSim 3.2

The Workshop Software

OpenSim Workshop

• Set clear and manageable project goals

• Help each other

• Use your resources: lectures and online materials

• Still need help? Find the right person to ask your questions

• Have fun and take breaks

Getting the most out of the workshop:

OpenSim Workshop

• Continue to use OpenSim in your research

• Develop musculoskeletal models and contribute them to the biomechanics community

• Use OpenSim in your teaching and contribute new teaching materials

• Add features to the software and share with others

• Complete our survey so we can improve later workshops

How we hope you will respond:
