BlinkTalker

BlinkTalker is an app that allows you to talk by blinking.
No complicated calibration or settings are required.
You can start using it immediately after downloading.

With the combination of blinking with both eyes and blinking with one eye (wink), you can enter characters to create a sentence.
You can also enter the customized words and sentences.
The text you enter can be read aloud by a synthetic voice.

BlinkTalker only works on hardware with Face ID.
Since the built-in camera is used to detect blinks, it may not operate as expected depending on the environment and conditions of use.

* Important notes
Please do not use BlinkTalker continuously for a long time, and use it with appropriate breaks.
If you feel tired or uncomfortable while using BlinkTalker, stop using it immediately.
