DB9 Guidelines
Overview
This Ninapro dataset includes kinematic data from 77 intact subjects
acquired with a Cyberglove-II.
Publications
The dataset is described in detail in the following scientific paper.
Please, refer to it for detailed guidelines and cite it in case you use
this dataset.
Instructions
Subjects
77 intact subjects, respectively from Ninapro DB1, DB2, DB5.
Acquisition Setup
22 sensors Cyberglove-II.
Acquisition Protocol
The experiment is divided in the following exercises:
- Basic movements of the fingers.
- Grasping and functional movements.
Dataset variables
For each exercise, for each subject, the database contains one matlab file
with synchronized variables. The variables included in the matlab 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 procedure.
- 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.
Usage notes
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.
Acquisition procedure. The subjects are asked to mimic movies of movement
shown on the screen of the laptop. sEMG signal is recorded with 10
electrodes (red, blue; the electrode on the flexor digitorum superficialis
and part of the equally spaced electrodes are not represented due to
perspective reasons).
Hand movements. Performed exercises: B, C.
