Context Contains neural activity data from hand muscle readings and simultaneous hand motion capture. Five sessions were recorded from the same hand in a short timespan. EMG sensors were not displaced during all five recordings. During each session two files were recorded in parallel: - csv files contain neural activity recorded like here [https://www.kaggle.com/kyr7plus/emg-4][1], but instead of motion class labels there are timestamps - json files were recorded with Leap Motion capture device using this program [https://github.com/kyr7/leapjs-playback][2]. Leap motion format is specified [here][3] Timing alignment was tricky here, because two independent software systems were used. First thing that could be done is alignment of motion by spikes in data. On the bright side, both sources were written from the same PC simultaneously.
