Considering potential benefits of vibrations in mobile phones,we propose an intuitive method to render human emotions for the vi-sually impaired. A mobile phone is "synchronized" with emotional in-formation extracted from human lips dynamics. By holding the mobilephone, the user will be able to get on-line emotion information of others.Experimental results based on usability evaluation of the system are encouraging. The user studies show a perfect pattern recognition accuracy on the designed vibration patterns.
