On popular request, I have uploaded some data sets of recorded signals, along with videos of their recordings.
They can be found in the new git repository "psylink-datasets". Here's a quick overview:
Spelling Out "hello"
Here, I recorded 4 different gestures to produce 4 different keys, "h", "e", "l" and "o", obiously to be able to spell out the word "hello".
Here I perform various arm movements and simply display/record their signals.
