How to use Hand Talk, Libra translator

Libras is the sign language used by the deaf community in Brazil. According to the Libras.com.br website, different from what many people think, Libras is not Brazilian Portuguese represented in gestures, but a language of its own.

  2. Open Hand Talk. You will be welcomed by the virtual assistant Hugo;

  • If this is your first time using the app, give permission for the program to record audios.
  1. If you want to learn the gestures better, access the side menu. If it is not showing, go to the three dots icon, located next to the text box;
  2. When touching the back arrow symbol, Hugo will repeat the last movement;
  3. On the two arrows to the right, the character repeats the movements at a faster pace (if pressed once) or slower (if pressed twice);
  4. In the star symbol, it is possible to evaluate the gesture, but for that, it is necessary to create an account on the service. If that’s what you want, go to Create account, which appears in the window that opens;
  5. It is possible to create a quick access with the Facebook or Gmail account or by entering email address and password. Choose the one you prefer;
  6. Back to the side menu, the square icon with an arrow allows you to create an animated GIF of the movement and share it through other apps, such as WhatsApp, e-mail, Drive, Instagram, among others.

In History , all translations already made in the app are displayed. For that, it is necessary to have an account associated with the service.

More apps with a focus on accessibility

Technology can even be a great ally for people with disabilities, whether physical or intellectual. Increasingly, applications appear with the aim of making life easier for these people. Here are some great examples:

Be my eyes

The Be my eyes is a free app for Android and iOS facing visually impaired. The goal is for volunteer psychics to help virtually blind or low vision people, acting as their eyes.

The developers report that the software does not efficiently identify handwritten text or cursive fonts.
