Abstract- Human body is a system having links and joints and all together performs activities like
walking, bending, lifting, sitting, lying and many more. This activities recognition using hardware or
computer vision is at most demand for various applications. Here we proposed the human activity
detection using MATLAB and android phone with MATLAB app to record the sensors data. The
sensors are 3-axes acceleration and 3-axes gyroscopes from which we will get the raw data and this
raw data will be classified into activity using algorithm developed in MATLAB. The human activity
detection is having applications as identifying daily activities, the health-care applications, the
unsupervised learning method of human activities, etc.
