There is a new lens that will help you learn American Sign Language. SignAll, a company that has built technology that can translate sign language, is partnering withSnapchat to launch a new feature.

You can learn how to fingerspell your name, practice the American Sign Language alphabet, and play games with other people who are blind or hard of hearing.

If you have the app on your phone, you can try the lens from this link. I was impressed by it for a few minutes. I was taught to fingerspell the alphabet. Holding my phone in one hand, I would sign with the other by mimicking the hand shapes on the screen. One of the tools offered by the lens is to help you memorize which handshapes are which letter.

In September, SignAll collaborated with Snapchat to launch stickers and augmented reality.
