Keyboard is one of the most used input device. We All use social networks and several of us like to send sms.  Normally a text does not convey the full message unless we add some  emotions in it and the perfect way to add emotions in text messages is  to add smilies and emoticons. Smilies and Emoticons are graphical  representation of various moods but if graphical emotions are not  available, it can be expressed using special characters and symbols as  well made of special characters such as:
 
- :) - is a smile icon
 - :( - is a sad icon
 - :'( - is expression for crying
 - :-* - is a kiss icon
 - :-x - is icon to express speechless or silence
