A engineering college Abstract— Recently, many interestingsystems on mobile phone are introduced to prevent the dangerous activity oftexting while driving (T&D). However these systems require user’s manualinput to block the texting activity or some extra devices are used to identifyuser’s location and also some localization techniques are used. Here the ideais to propose a method which is able to detect T&D without any userintervention. To implement this idea various smart phone embedded sensors suchas gyroscopes, accelerometers and GPS are used. They are used to collect theinformation such as touch strokes, holding orientation and vehicle speed. Usingthese patterns the whether the T&D is existing or not identified.
Keywords— Vehicles, Smartphones, Global Positioning System, Accelerometers.I.INTRODUCTIONSmartphones are small computers which uses android as operating system. Datacommunication between the people/user has become faster using smart phones.Calling and texting otherwise called as messaging is the most important andbasic activity that has been done using smart phones. But texting while drivinghas become most common habit between the drivers. This is one of the mosthazardous thing performed by the users of smart phone. This act becomes majordistraction from driving.
This leads to road accidents and causes damage to thedrivers and also other common people. Usage of mobile phones while driving canaffect your alertness of surroundings, which leads to accidents. This term inshort is referred to as T&D that is Texting while Driving. This isconsidered as one of the top most dangerous activity done by the drivers. Aresearch says that, the drivers who send messages while driving are 23 timesmore likely to experience a crash on others when compared to other drivers whoare dialing, talking or listening. Even though, many laws are imposed to avoidT&D, the users are involving in this activity. To stop these activity ofdrivers and to identify the T&D, many mobile apps are now developed andpractised between the users.
Thissystem does not require any manual input from the driver. This acts as themajor advantage of this over other T&D system. In other detection systemthe major problem is they require user input or activation or it eitherdisables all the mobile phones in the user location (such as car) , this causesunnecessary inconvenience to the users. The key challenge is detecting whetherthe mobile phone belongs to driver or passenger.
For this purpose, some systemsuses camera to monitor driver’s activities. But this method is infrastructureheavy and required high hardware facilities to implement real time videoprocessing. Some of the works are done for detecting T basedlocalization. Here some extra devices in combination with mobile phone workcollaboratively to determine the user location.
To enlighten this idea mostsuccessfully a method which does not require any extra devices except user’smobile phone was needed. Here are somepatters that is used to distinguish between the driver and the passenger. Pattern1:Editing messages after the car speed is decreased.Pattern2: Stop editing when the car is taking turns.Pattern3: Holding the mobile phone uprightly while editing the messages.
Thereforeby using this system the T&D patterns are identified by the data collectedthe smart phones and the other embedded sensors like accelerometers, gyroscopesand GPS. The other important factor is that, this system does not try to readthe content of the messages. Therefore privacy is preserved here.
II.RELATED WORKSTheexisting system to prevent T&D there are two categories, the first one iswhich simply blocks all the messages from the user end. The best example forthis is driver mode or bike mode available in the mobile phones. But thisexisting system does not identify the drivers mobile with the passengers. Thenext category is identifying whether the mobile is used drivers or passengersand it blocks the driver’s mobile only. In this method identifying the locationof the mobile phone in the vehicle is important.
For this localizationtechniques are used to identify the driver’s location. However this approachhas some drawbacks that identifying the driver’s location requires some specialsensors and required high deployment cost. Identification of driver’s locationand driving patters in also infrastructure heavy and intrusive.Thereforefor overcoming these drawbacks infrastructure-less approach is required. Thatis identifying the driver’s usage of mobile without any extra devises excepthis/her own mobile phone.III.
TOUCH STROKE DETECTIONHere the touch strokesare identified by using the gyroscope data. Using the training data set a touchstroke template is constructed. On this gyroscope data the template is utilizedas wavelet basis and they carry out wavelet transform. According to the occurrenceof touch strokes the significant peaks and the location of the peaks are selected.IV.LITRATURE SURVEY1SAFECAM: Analyzingintersection related driver behaviours using multi sensor smart phonesThisuses embedded sensors on the phone .It is used in tracking different drivingconditions.
