A new app is trying to make it simpler to help you react to photos and videos that your friends post online---it’s using AI to capture(捕捉) your facial expressions and automatically translate them into a range of emoji(表情符号) faces.

Polygram, which is free and available only for the iPhone for now, is a social app that lets you share things like photos, videos, and messages.

Unlike on Facebook, though, where you have a small range of pre-set reactions to choose from beyond clicking a little thumbs-up icon(图标), Polygram uses a neural(神经的) network that runs locally on the phone to figure out if you’re smiling, bored, embarrassed, surprised, etc.

Marcin Kemiec, one of Polygram ‘s founders, says the app’s AI works by capturing your face with the front-facing camera on the phone and analyzing the images as quickly as possible, rather than just looking at specific points on the face like your eyes and nose. This is done directly on the phone, using the iPhone’s picture processing unit, he says.

When you look at a post in the app, you see a small yellow emoji on the bottom of the display, its expression changing along with your real one.

There’s a slight delay—20 milliseconds, which is just hard to notice—between what you’re expressing on your face and what shows up in the app. The app records your responses in a little log of emoji on the side of the screen, along with those of others who’ve already looked at the same post.

The app is meant to appeal to those who really care about how they’re understood on social media. Users can see a record of the emoji reactions to each photo or video they post to the app, as well as details about who looked at the post, how long they looked at it, and where they’re located.

Eventually, the founders say, they may release software tools that let other developers come up with their own applications for the technology.
