Would you like if your emotions are being detected withouht your consetiment? Technology is every day beging more capable of new things, in terms of artificial intelligenece. The new software has been developled so that it can read or decode the emotions of others. Dr. Eckman has classified six bassic emotions - happiness, surprise, anger, disgust, fear, and sadness-, he assocciated each emotion with movements on the facial muscles.

It is important to know how the muscles in our body , in our face works , and what an amazing way to know through technology. But at the point to that technology knows what are your emotions to then use them on "what you need" is not correct. I am not saying that when we want to search about emotions through technology there should not be anything on it. But what if we are trying to hide emotions for our or others good and technology just cames and reads or decodes your emotions how would you feel?

It is also important to know the basic of emotions, because that how you express yourself.
