MSRDailyActivity3D is a collection of daily activity data acquired by Kinect devices for the study of human behavior recognition. The total number of activity samples in this dataset is 320, covering 16 types of daily activities such as drinking, eating, reading, making phone calls, playing guitar, etc. This dataset is designed to include daily human activities in the living room. When volunteers stand near or sit on the sofa, the 3D joint positions extracted by the Google tracker are very noisy. In addition, most of the activities in this dataset also involve content of human interaction, which is more challenging.
