BaSA – Basic Step Activities
Hardware Equipment and Sensor Setup
Two SHIMMER (Shimmer Research, Dublin, Ireland) sensors were used for data acquisition. Each sensor node was equipped with a triaxial accelerometer and a triaxial gyroscope. Data were sampled with 200 Hz and were stored on SD card.
The Basic Step Activities database consists of data from 15 subjects (8 female and 7 male, age 23 ± 2 years, height 178 ± 12.5 cm, weight 75.0 ± 16.5 kg, mean ± standard deviation (SD)) that performed 7 daily life activities. All subjects gave written informed consent.
The 7 activities were:
- Walking outside
- Jogging outside
- Ascending stairs
- Descending stairs
These activities were chosen according to their different Metabolic Equivalent of Task (MET) values.
