The intention of the USC Human Activity Dataset (USC-HAD) is to serve as a benchmark for human activity recognition algorithm comparison and make research efforts based on it repeatable and extendible by researchers in ubiquitous computing and machine learning communities. The dataset is specifically designed to include the most basic and common low-level human activities in daily life from a large and diverse group of human subjects. Our own focus is on healthcare related applications such as physical fitness monitoring and elder care, but the activities in the dataset are applicable to many scenarios. The activity data is captured by a high-performance factory-calibrated inertial sensing device called MotionNode and is well-annotated. In total, we have included 12 activities and collected data from 14 subjects. Here is a list of summarized properties of the dataset:
- The data is captured by the MotionNode inertial sensing device which integrates an 3-axis accelerometer (+-6g) and an 3-axis gyroscope (+-500dps), sampled at 100 Hz.
- MotionNode was worn on the front right hip of the subjects during data collection.
- The 12 low-level human activities include: walk forward, walk left, walk right, go upstairs, go downstairs, run forward, jump up and down, sit and fidget, stand, sleep, elevator up, and elevator down.
- In order to capture the dayto-day activity variations, each subject was asked to perform 5 trials for each activity on different days at various indoor and outdoor locations. Although the duration of each trial varies across different activities, it is long enough to capture all the information of each performed activity.
