ISRMyo-I: A database for sEMG-based hand gesture recognition

## Hand Gestures

The sEMG signals of thirty hand gestures were colleced, as listed below:

* Label 0: Hand Rest (HR)

* Label 1: Hand Open (HO) 

* Label 2: Hand Closed (HC)

* Label 3: Wrist Flexion (WF) 

* Label 4: Wrist Extension (WE) 

* Label 5: Wrist Pronation (WP) 

* Label 6: Wrist Supination (WS)  

* Label 7: Ulnar Flexion (UF)  

* Label 8: Radial Flexion (RF) 

* Label 9: Fine Pinch (FP) 

* Label 10: Key Pitch (KP)  

* Label 11: Spherical Grasp (SG)  

* Label 12: Cylindrical Grasp (CG) 

## Database Organisation

* emgData/RawEMG: the folder that contains the raw recorded signal directly from the device without any processing

* emgData/RawEMG/XXXX: the folder named by subjects' name, the data of which is contained 

* emgData/RawEMG/XXXX/EMGDDS.txt: the data file titled by EMG*dds*.txt, where *dd*, *s* indicate the ID of day and the ID of the session, respectively.

* emgData/train_XXXX: the folder that contained the training samples (first 7 days) after segmentation and prcessing from the raw EMG , where XXXX indicates the subject' name

* emgData/test_XXXX: the folder that contained the testing samples (last 3 days) after segmentation and prcessing, where XXXX indicates the subject's name

* emgData/train_XXXX/CXX_train.txt: the segmented training samples of channel XX. Each row in the file contains 256 scale value, indicating an observation from channel XX.  

* emgData/train_XXXX/X.txt: the extracted TDAR feature (128 dimension) extracted from all segmented data from CXX_train.txt, where 16 channels were collected in a line.

* emgData/train_XXXX/y.txt: the lable of training samples, and each row corresponding to each row in CXX_train.txt and X.txt

* emgData/test_XXXX/CXX_train.txt: the segmented testing samples of channel XX. Each row in the file contains 256 scale value, indicating an observation from channel XX.  

* emgData/test_XXXX/X.txt: the extracted TDAR feature (128 dimension) as testing samples extracted from all segmented data from CXX_train.txt, where 16 channels were collected in a line.

* emgData/test_XXXX/y.txt: the lable of testing samples, and each row corresponding to each row in CXX_train.txt and X.txt
