Rate the following essay on its writing, argument, and language skills:
A new technology called Facial Action Coding System claims it can scan a face and tell how much of each emotion the person is feeling. There are some negatives and some positives to bringing this new technology to personal computer. The author of the passage seems to only give a positive outlook on this system, when all aspects should be explored. The negatives to this technology would not be the end all be all of this product, but they should definitely be taken into account for the creation of a better system.

The Facial Action Coding System is a computer software that scans a face and recognizes what emotions are being displayed on the face. It uses codes to see which muscles are being used to move a face. For example there are certain muscles to show anger like the orbicularis oris which tightens your lips. The system uses these muscle movements to determine which emotion is being displayed and/or felt.

Although there are a few negatives to the FACS, it could potentially be a useful product. The passage says that the Facial Action Coding System could be used for relevant advertisements and a more engaging classroom effect. This system could be very helpful for ad agencies that don't know how to reach their public. If a computer scanned a face the instant it sees an ad, researchers could figure out whether or not to show an ad again. For example, an ad for cat litter with a picture of a cat could potentially produce a smile or a look of disgust depending on a situation. If the person doesn't own or like cats their face would not show happiness, and the ad agency could show a different ad. This system would also aide online class courses. If it was constantly scanning a person's face, the creator or teacher of the class could modify which sections seem to bore a student.

The system may be helpful, but the negative sides to it should be also considered. Because the FACS can only guess what someone is feeling by what is being displayed on a face, it could potentially be inaccurate for people that are prone to hide their actual feelings from their faces. The FACS only does an outerscan, it never sees what is happening in the brain. A scanner of the brain would be more accurate, expecially for people that can not or do not want to show their true emotions. Another possibly negative fact about this system is that it would need to constantly be scanning a person's face for accurate readings. This could become innacurate if used for a very long time. If it were used for an online course, the system would need to be running during the entire class, and the person could get distracted and show emotions for the distraction that are not relevant to the class. This is also potentially invasive, especially for a company using FACS to show relevant ads. People might not want to constantly be scanned for their emotions. There would be a paranoia of always being watched and unless the software company promises the facial recognition would never be used for anything other than for the ad display or for fixing a class, people would feel uneasy.

It seems evident that the author of this passage is giving the readers a positive look into the new Facial Action Coding System, but it should be taken into account that there are negative aspects to this software. People may not always want to be watched for their emotions, and the system could become inanccurate. Although it seems that the passage points towards effective and positive outcomes, the negative criticism should be taken into account and modified for a better FACS.
