The format and content for data sets are described hereafter. For each subject and exercise, the database contains one .mat file with synchronized variables. The variables included in the files are:
• subject: subject number;
• exercise: exercise number;
• glove (22 columns): uncalibrated signal from the 22 sensors of the Cyberglove. Details on the location of the sensors are described in figure 1;
• angles (22 columns): calibrated signal from the 22 sensors of the Cyberglove by applying the post-processing calibration procedure10.
• inclin (2 columns): inclinometer (roll,pitch) values;
• restimulus (1 column): the a-posteriori refined label of the movement;
• rerepetition (1 column): restimulus repetition index;
order of angles (22 columns): the name of each column that corres
Many factors can affect the amplitude of the signal from the sensors, including the acquisition setup, the anatomical characteristics of the subject, and fatigue, among others.
Sensor 11 (which corresponds to MCP2-3_A) was not included into the calibrated data due to noise problems.
DIP sensors provide reliable angles when subject hand size is big (i.e. when the glove fits properly to the hand). Instead, the may provide partial results when the hand of the subject is small. Therefore, attention should be taken when using their information.
