MultiPosture: A Dataset of body joints keypoints extracted using MediaPipe for multi-task sitting posture recognition with upper and lower body labels

This dataset contains skeletal pose data extracted from video recordings of 13 participants performing various sitting postures in home environments. The data was processed using MediaPipe Pose Heavy model and includes 4,800 frames of 3D skeletal coordinates (x, y, z) for 11 key body joints, with each frame manually labeled for both upper and lower body posture classifications.

The data is stored in CSV format with normalized coordinates relative to hip center, containing 33 input dimensions (11 joints × 3 coordinates) representing key skeletal points. To protect participant privacy, only the processed skeletal coordinates are included, with no raw video or image data due to privacy constraints.

Upper Body Labels:

• TUP: Upright trunk position
• TLB: Trunk leaning backward
• TLF: Trunk leaning forward
• TLR: Trunk leaning right
• TLL: Trunk leaning left

Lower Body Labels:

• LAP: Legs apart
• LWA: Legs wide apart
• LCS: Legs closed
• LCR: Legs crossed right over left
• LCL: Legs crossed left over right
• LLR: Legs lateral right
• LLL: Legs lateral left

Each frame in the dataset has been manually labeled and validated by experts, making it particularly suitable for developing and evaluating machine learning models for ergonomic monitoring systems, ambient assisted living applications, and general posture recognition research.
