AUTOMATIC SWITCHING OF MOBILE PHONE PROFILE BASED ON CURRENT SPEED OF THE VECHILE
A method of automatically switching a profile of a mobile phone comprising a)Measuring the current speed of the vehicle in mobile phone b) compare the current speed with predefined threshold speed c) switching of profile of the mobile based on the comparison result obtained from step b.
The current speed of the vehicle can be obtained either by using GPS speedometer which nowadays comes as inbuilt application in modern mobile phones or by using Bluetooth device attached to the speedometer which transmit the data to the mobile phone.
If the speed obtained from GPS Speedometer exceeds the predefined threshold speed, then the profile will automatically switch to Ëœsilent modeâ„¢ from any other mode (Loud, Normal, Vibrate etc.,) as shown in fig 1 and in the mean time if the user get any callâ„¢s the caller will get a message stating User is on Driving...So please call back after XX minutes and if its emergency, call 2 more time continuously. The value of XX can be set by the user in the initial stage itself.
In emergencies if the caller is calling from the same number and if the call count equals to three times then automatically mobile phone switches a profile back to ËœNormal or Loudâ„¢ from Ëœsilent modeâ„¢. Once the user drops the call the speed will be compared and the process continues.
Consider a situation that the user is driving, he may stop the vehicle in road signals. In this case if the speed is compared surely it will be less than the predefined threshold speed during these time period there is a possibility that the user might get any call which will distract the user attention and it may lead to accident. In order to verify whether the user came to idle or the vehicle halts in road signal, we uses a timer (T) which startsâ„¢s automatically when the speed of the vehicle reaches below the threshold speed. Between these time periods the mobile phone should not change its profile it has to wait for 60 sec to ensure whether the user came to rest or the vehicle stops in road signal. In short, if the time difference between user halt the vehicle in road signal (t1) and started the driving again(t2) is less than or equal to 60 sec then the mobile will stay back in ËœSilent modeâ„¢ as shown in fig 2. Else it comes to conclusion that user came to rest and it will change the profile back to ËœLoud or Normal modeâ„¢ as shown in fig 3.
Note: We have taken the timer value as 60 seconds because in India majority of the road signal will have a timer of 60 seconds.
