If the work you do often needs to deal with different people, then you must know that some strange people are very difficult to engage. Maybe he was still laughing a second before, and he became angry in the next second. At this time, you must hope that you will "read the mind" - because then you can directly read the fluctuations of the other party's heart, prepare in advance and take appropriate countermeasures.
Regrettably, "reading mind" does not exist in real life. However, you can use the artificial intelligence program called Affdex to complete the "reading heart" work.
When it comes to Affdex, you have to mention a startup called Affectiva. The startup, founded in 2009, is dedicated to the development of emotional feedback machines. Many commercial media have ranked Affectiva as one of the fastest growing startups in the US, and Affdex is the core product of Affectiva.
What is Affdex?
A person's inner feelings can be interpreted by a person's physical movements, language, and facial expressions. Among the three, facial expressions often carry more emotional information. Therefore, through the recognition of human facial expressions, it can help us to understand a person's emotional changes to some extent. Affdex can help us with this.
In short, Affdex recognizes a person's facial expression by scanning the face, and interprets the fluctuation of a person's inner feelings based on the recognition result of the facial expression.
After completing the collection of the human face image, Affdex will automatically identify the face of the person's face such as eyes, nose, mouth, eyebrows, and establish corresponding anchor points in different parts. These anchor points can be divided into two categories: stable anchor points and moving anchor points.
After completing the collection of the human face image, Affdex will establish an anchor point in a specific part.
Take laughter as an example. When we are laughing, the corners of the mouth, eyes, eyebrows, etc. will change, and because of the degree of our laugh, the changes in these parts are different. At this time, the anchor points established based on these parts are all movable and belong to the moving anchor point. But in the process of changing your degree of laughter, the position of your nose does not change, so the anchor point based on the tip of the nose is a stable anchor.
Since moving the anchor point does not help us determine the entire facial expression, this time we need to have a stable anchor point to help stabilize the establishment of the entire facial expression model. When the anchor point is created, Affdex will create a geometric model based on these anchor points and render it, and finally complete the facial expression recognition.
Affdex will create a geometric model based on these anchor points and render it, and finally realize the recognition of facial expressions.
Because the geometric model established by the anchor point is not accurate when performing facial expression recognition, in addition to modeling, Affdex also captures changes in skin fine lines to assist in the recognition of expressions. Still taking laughter as an example: when laughing, people's eyes and corners of the mouth will appear corresponding lines, these fine lines of skin can become the reference for Affdex for expression recognition.
In addition to recognizing your expression, Affdex also calculates metrics that reflect your emotions and compares this data to the database of expressions you have equipped to derive your joy and anger as a percentage of your feelings. .
Affdex also calculates some metrics that reflect your mood.
It is worth mentioning that Affdex not only supports the expression recognition of individual individuals, but also can complete the expression recognition of multiple individuals. When there are more than two targets in the captured face image, Affdex will analyze the different targets separately.
At present, Affdex has analyzed more than 8 million faces and accumulated more than 40 billion expression data. In the process of accumulating these data, a total of 15,000 people participated in the test, and these testers covered more than 75 countries in the world. But from a data point of view, this is a very large amount of data. For this reason, Affectiva said that it has the world's largest "emotional database."
What can Affdex do for us?
In fact, Affectiva's initial motivation for developing the Affdex project was to facilitate communication with children with autism. Because most children with autism have language barriers, they hope to interpret the expressions of these autistic children through Affdex, to facilitate communication with them, and to facilitate psychological counseling.
But in fact, the application of Affdex is definitely more than just caring for children with autism. In the commercial field, Affdex can also be used for many purposes.
For example, when making commercials, producers often have a headache: when should the trademark logo be inserted, and when should the product image be popped out to give viewers a deeper impression of the brand and the product? And Affdex can help ad makers solve this headache.
The author only needs to invite some people to try this commercial after the commercial is completed, and use Affdex to test the viewer's emotional changes during the trial to find the paragraph with the most emotional fluctuations. This is the best logo insertion paragraph.
In addition to helping ad creators find the best logo placement point, Affdex can help filmmakers find the most appealing part of a movie to make a movie trailer to ensure that the trailer is attractive enough to ensure More people are willing to walk into the cinema to watch the "positive film" after watching the trailer.
In addition to Affdex, many artificial intelligence programs can provide a lot of help for our work and life. I believe that with the help of artificial intelligence, our life will become more and more beautiful.
