Rate the following essay on its writing, argument, and language skills:
The use of this technology is not valuable because ,it will not always be accurate .You can't tell from a 400 year old painting that Mona Lisa was 83 percent happy ,9 percent disgusted ,6 percent fearful ,and 2 percent angry .That just doesn't make any sense .You can usually tell what kind of emotion a person is feeling .Just by looking at a persons facial expression you can tell if someone is happy ,sad ,or mad .

On the other hand though this kind of technolgy could be useful .Here is how this program works .A computer constucts a 3-D model of the face ; all 44 major muscles in the model must move like human msucles .The movement of one or more muscle is called an action unit .The computer detects 6 emotions happiness ,suprise ,anger ,disgust ,fear ,and sadness .

In everday life you can tell how a person is doing .Like if my friend walked up to me with his head down ,I can most likley tell ,that he is sad or angry .You can also tell persons emotion by looking at body movements something a computer can't do .

There is another benefit to this computer .If you are in class and you just have a blank stare the computer can tell if you are confused or bored .Then it could also modify the lesson .Another example is for online advertisment .If I see an ad that I like and I smile ,then I scroll down and see a similar ad ,but I frown ,it will change the ad just becuase I frowned .This is the same technology used in video games and video surgery .

In my opinion i dont think this kind technology would be valuable .It might not be accurate all the time and it would cost a lot of money .Instead of using this you can just look at a person and see there emotion .
