Polar Verity Sense Wrist-PPG Emotion Dataset (WPED) This dataset contains raw wrist photoplethysmography (PPG) recordings from 10 healthy volunteers (age 20–24; 7 male, 3 female), collected with the Polar Verity Sense sensor at 176 Hz. Each recording lasts 2–4 minutes and is organized by subject and emotion: Subject_ID/ ID/ anger.txt # PPG during an anger-eliciting clip joy.txt # PPG during a joy-eliciting clip sadness.txt # PPG during a sadness-eliciting clip relaxed.txt # PPG during a relaxation clip Emotion elicitation was done via a combination of professionally produced movie clips and publicly available YouTube videos, selected to reliably provoke the target affect. Each .txt file contains one column of raw sensor readings (no headers), sampled at 176 Hz. License: CC BY 4.0
