A Review on Human-Computer Interaction using Smartphone's Inertial Sensors

Nowadays mobile phones have become minicomputers equipped with inertial sensors due to advancement in microelectronics, which increases the processing power of these devices and has made possible new forms of input interfaces like gesture-based user interfaces. Because of this, a new type of interaction has been introduced in which the user interacts with the computer using movements or gestures made while holding a device. A gesture recognition system has been proposed for mobile devices using the measurements of accelerometer and gyroscope. The system has been set in which predefined gestures are loaded and they are recognized in a user-independent way, without the need of learning phase. The system has low computational complexity so that the events can be executed in real-time on devices with limited capabilities. Using this system, we are trying to reduce the dependability on conventional input devices which are used to control computer system.
