The USC Human Activity Dataset (USC-HAD)

Dataset Description

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:
