Most of research work has focused to car driving. However, using motorbike is very popular in some developing countries such as Vietnam, India, etc. Up to now, there are just a few works, which focus to motorbike driving with obvious limitations. Thus, in this research, we proposed a complete solution for bikers who own a smartphone. Our work exploits the information from built-in sensors in Android smartphone. A complete scheme for motorbike driving is proposed. In this scheme, the user state is detected by improving the current Google activity recognition API. If the state is “On vehicle”, the phone automatically switches to silent mode and send to the caller an SMS. Our work provides a mechanism to receive the calls from VIP contacts and urgent calls. The phone would switch back to the normal mode if the state is not "On vehicle". Furthermore, it sends the accident location to the relatives when an accident occurs to save their lives automatically. The application was tested carefully and it can be used to protect the lives of motorbike drivers. %N 2 %P 871-881 %V 9 %D 2015 %I Engg Journals Publications %L SisLab2480
