Controlling And Operating Mobile Device Through Sensors

Last years have been characterized by an incredible growth in mobile computing capabilities and sensing technologies, which can leverage the deployment of many location-based applications, ranging from pedometers to navigation system. This work deals with an Inertial Navigation System (INS) able to support users in the navigation in an unknown indoor environment by continuously calculating their motions and their position. The proposed solution is based on integrated use of movement and position sensors. Unfortunately, applications that rely on the use of measures coming from orientation sensors, such accelerometers and digital compasses, are affected by external magnetic interferences thus resulting in inaccurate directional information. This paper focuses on this problem by investigating the use of the gyroscope as the primary determinant of better orientation information. Nowadays, modern mobile devices, such as smartphones come to the market already equipped with sensors able to track them as they move, both in outdoor and in indoor environment. Taking advantage of the present hardware in the smartphone, we aim to create an application that can perform certain task or procedures which can be set by the user and it will trigger that operation by the movement the smartphone device in the specific pattern which is determined by the sensors from the smartphone.
