Suddenly there is a change in emotions based on such new information. So, the change in the user's emotion needs to be determined and simultaneously shared with any secondary user.

[0069] In an embodiment, this change of emotions is dynamic and real-time. This change occurs because of the change in the state of another user. This change is determined by the biosensors connected to user s body wirelessly or by the wired medium. The change in biorhythm of the user determined the change and the change in emotions are conveyed to the communication channel to the second user if the user allows permission. In an embodiment, a threshold can be pre-determined, based on the threshold and breaching the threshold, the system and the method change the user communication to another channel to relax and/or calm the user. In an embodiment, the other user can also get the information based on the score about the user's emotions over the communication channel.
