TMS Meeting Minutes, September 03, 2020

Attendees: Andrew, Breann, Heejoo, John, Matthieu, Trenton, Yang (Zoom meeting)

Meeting discussion summary:

  • We discussed TMS pose/pose change calculations with missing channel information. We have previously concluded that the we will be using the "change of change of pose" method (aka "pose acceleration") to handle missing channel information during a reference step. Andrew and Yang exchanged some further discussions regarding the effects of the "permanent reference vector" on the results of such calculation. We have since decided to use a more recent TMS real measurement vector to act as our "permanent reference vector" in this computation step (which worked fine for the examples we constructed). Using the vector derived from the truss geometry seems to make the system somewhat nonlinear and causes large errors. In the future, we will also periodically update this "permanent reference vector" with more up-to-date TMS measurement data.
  • Discussion on the possible second TMS test.
    • Scope of the test: we mainly want to test the TMS calculations when channel information are missing.
    • Time of the test: that depends on the readiness of the current TMS software prototype. Yang will give another status update in the meeting next week. But it is estimated that we shall be able to conduct a TMS test in the week of Sep 14 -- 18.
  • We had some discussions on the LBC IQ maps created by Christian.
  • Some other discussions related to linear-fit software and possible dissertation/research work for Trenton.

Action Items:

  • Yang will work on the software prototype and be ready for the upcoming TMS test.
  • Andrew will perform some further study on the choice of "permanent reference vector" and its effects on calculations with missing channels (e.g., using some older TMS measurement data).
  • John will share some LBC focus images/information for anyone interested to play with.
