Reference | Algorithm/best accuracy reported | How is data collected | Task |
---|---|---|---|
Russell et al. (2021) | CNN 97.8% | accelerometer worn around the chest, GPS watch for location tracking, 1 person | HAR: Climb Gate/Lay/Sit/Walk/Run. Variations in terrain and fatigue |
Baghdadi et al. (2021) | MHTSCA with DTW as a dissimilarity measure | IMU worn at the right ankle 15 subjects | fatigue development over time |
Sedighi Maman et al. (2020) | RF with BSS 85.5% | one sensor in the torso, 15 subjects | 4-phase fatigue management framework in the workplace (1) detection (2) Identification (3) diagnosis: whole-body vs. localized (4) recovery |
Maghded et al. (2020) | CNN/RNN | smartphone sensors, images and videos from the camera | detection of fatigue due to Covid-19 |
Karvekar, (2019) | 2-class SVM 91% | 24 subjects, smartphone attached to the shank | detection of fatigue: baseline, low, medium, and strong fatigued states |
3-class SVM 76% | |||
4-class SVM 61% | |||
Baghdadi et al. (2018) | SVM 90% | one IMU in the ankle, 20 subjects | detection of fatigue after MMH tasks |
Zhang et al. (2014a) | SVM 96% | 17 subjects, IMU at sternum level | recognition of localized fatigued/non-fatigued state |
Janssen et al. (2011) | SVM and SOM with PCA 98.1% | 9 subjects GRFs | inter and intra-personal gait classification before, during, and after leg exhaustion |
