Yes, it could be that MATLAB is doing some compiling on the first run to speed up the later ones. I have no reference to that but I have heard that that happens before.

It’s in Erlangen, Germany

Dankjewel!

Yes please!

It’s a personal preference. I was once asked to combine two bracketed phrases in the same sentence into one.

For sagittal plane movements, the orientation of the axis perpendicular to the plane can probably be estimated from the movement itself rather than special calibration movements. For 3D movements, I’m not sure. A direct optimization or ML model might work, but should be developed and tested first.

So yes! (Should have answered both messages at the same time). It depends on your definition of assuming but we measure the position (with a scale or with a marker on the IMU) and estimate the alignment using the gravity direction and calibration movements (in the sagittal plane “only”)

Yes, you could even do that without using orientation data and use the optimization to find the optimal alignment and orientation estimation. We did this with a machine learning approach and it worked quite well for the position. We’re still working on that publication.

Yup, that is actually pretty similar. We have now also published code that can be used create the simulations here: github.com/mad-lab-fau/...

What info do you want exactly? The methods are described here: www.sciencedirect.com/science/arti... and here: www.frontiersin.org/journals/bio.... I’d be happy to add more information!

We use the acceleration, angular velocities, and position and orientation of the sensor on the body segment but do not use IK. I think that you probably do not need the information very precisely if you have a musculoskeletal model for IK since the model limits the motion to reasonable ones.

I’ll come and laugh! I might steal it for my next course 🤣

Due to administrative rules, we can only provide the reimbursement after the conference has taken place. We are still trying to find a workaround for this.

To sign up, send the following information, as single PDF of <3 pages, to anne.koelewijn(at)fau.de with subject: “ISB-FAME Travel Support”, until 23.03:
- Why you are part of an underrepresented group or your country of origin (<½ page)
- Motivation to join the tutorial (<½ page)
- CV (2 pages)

We can provide a reimbursement for the registration fee for the conference and the tutorial. The support is based on the early bird registration fee and includes the aforementioned tutorial. We will reimburse the conference fee converted to € according to the conversion rate on the day of payment.

YES! Please consider that ONE DAY might not be enough. Let's follow this expert's advice:
