The goal of this study is developing the fundamental techniques to define activity of the users like walking, running, standing or cycling while the user is using two different type of Network connectivity, GPRS or Wi-Fi by calculating the distance of the user in a period of time by the longitude and latitude of the user´s location which has reached in the location recognizing. Therefore, the main goal of the study to retrieve user’s activity is achieved by requesting location of user for each period of time, from current and previous location of user.

Using Android cell-phones, and consequently, having access to the input provided by the GPS receiver and the WI-FI receiver as well, the project will require to develop the necessary software and associated algorithms in order to deduce the user's activities in terms of the location of the user (indoors or outdoors) and those activities derived from detecting if the user is standing still, walking, running, driving a car, riding a bicycle, etc.
