Upper-body movements: precise tracking of human motion using inertial sensors

The Upper-body movements: precise tracking of human motion using inertial sensors is a dataset composed of 11 participants' IMU data (5 women + 6 men). This collection is divided into 6 motion sets containing different motions for the upper-body.

Folder Structure

subject -> set -> IMU position -> file

e.g. subject01 -> set6 -> forearm -> Accelerometer.txt

IMU placement 

For data collection participants wore 4 IMUs:

1 on the chest

1 on the right arm

1 on the right forearm

1 on the right hand.

Sets

Each set includes:

 set1 - flexion/extension of the forearm; abduction/adduction of the arm; anatomical position

 set2 - flexion/extension of the wrist; radial/ulnar deviation of the wrist; anatomical position

 set3 - flexion/extension and lateral flexion of the torso; anatomical position

 set4 - flexion/extension of the arm; flexion/extension of the torso; anatomical position

 set5 - flexion/extension of the arm; anatomical position; anatomical position

 set6 - flexion/extension of the torso; flexion/extension of the arm; anatomical position

Annotations

This dataset is accompanied by the annotations.csv file.
Each file row present "Set,Subject,Category,Segment,Type,Init,End":

Set - sets 1-6

Subject - participant ID

Category - relative or absolute. Refers to the joint angle.

Absolute if the angle is obtained considering an anatomical plane as reference.

Relative if the angle is obtained from one segment in relation to another.

Type - segment at action (torso; right_arm_forearm; wrist; right_arm_sagittal)

Init/End - time in seconds, describing the begin and end of the motion, respectively.
