Hi, I want to load the head rotation and position signals (3 variables for rotation and 3 for position) in elan and I want it to show the synchronized rotation signals on a figure, so that when I plat it the bar moves forward on those as well. I could load those as values from csv file but I want them to be actually shown! like a figure going up and down when the person moves up/down (pitch rotation). I have the signals and the timestamp for each frame and related values in a csv file like this:
Yes, fully understandable. Unfortunately this is currently not possible, we don’t provide other visualisation for that type of data than time series as line plots or curves. This is already an item on our request list: adequate visualisation of 3D data.
That would be a very nice feature to have in ELAN!
Does this item on your list also include heatmaps or contour plots, or is it related only to 3D positional data? Having the ability to have time based heatmaps would be great for e.g. time frequency analysis results of EEG/ECG data, but also for audio features.
Hi,
I don’t think heatmaps and contour plots are already on the list as separate items, I can add them.
The fact that visualization of 3D data was already on the list 7 years ago, indicates that actual implementation of items on the request list is not guaranteed at all. Often changes of such extent (new viewer, new data structures) require an actual project (with funding) for its implementation.
What might be implemented first is a more generic extension mechanism for ELAN, so that it becomes easier to add custom, non-anticipated viewers to the application. “Easier” does not necessary mean ‘easy’; implementation of some types of viewers and visualization can be a lot of work, whoever does it.
