############################################### --Contact Details-- Name: James Male Institution: University of Bath, Dept. Electronic and Electrical Engineering Email: jjm53@bath.ac.uk Date: July 2022 ############################################### --Overview-- Data files for use in developing methods to predict the status of each user action in an assembly task. IMU and skeleton tracking data recorded along with ground truth data on how long until each action in a task is complete and whether the action has started and finished. ############################################### --Trial details-- Two assembly tasks are used; a wooden box and small chair. Three participants each record two assembly sequences of each assembly type. 3-axis accelerometer and gyroscope data from IMUs placed on the hand, wrist and upper arm, along with skeleton tracking data, are recorded. Action sequence for each task: Box: Action 1-12: Screwdriver Action 13-16: Allen key Action 17-18: Handscrew Action 19-22: Hammer Chair: Action 1-4: Hammer Action 5-6: Allen key Action 7-10: Screwdriver Action 11-14: Hand screw Skeleton tracking joints order: (from ROS openni tracker) [head, neck, torso, left_shoulder, left_elbow, left_hand, left_hip, left_knee, left_foot, right_shoulder, right_elbow, right_hand, right_hip, right_knee, right_foot] ############################################### --File structures-- Each trial has one input data file and one target data file. Input data file (imu_skeleton_data_user_X_take_X.csv): Column 1: timestamp Column 2-7: Hand IMU [Accel x, Accel y, Accel z, Gyro x, Gyro y, Gyro z] Column 8-13: Wrist IMU [Accel x, Accel y, Accel z, Gyro x, Gyro y, Gyro z] Column 14-19: Arm IMU [Accel x, Accel y, Accel z, Gyro x, Gyro y, Gyro z] Column 20-124: Skeleton tracking [pos x, pos y, pos z, orient x, orient y, orient z, orient w] for each joint location (see above) Target data file (Y_data_user_X_take_X_TASK.csv): Column 1: time step start (trial seconds) Column 2: time step end (trial seconds) Repeat for every action in task: Column 3: Time until action complete Column 4: Action started flag Column 5: Action complete flag ###############################################
