”User Interface for Voice-activated Drawing” is a voice recognition displaying technology that allows spoken words to be displayed on a screen where touched by a fingertip.
There are different ways to deal with hearing disabilities or language barriers, but each method has its own problems.
For example, you can converse with a person with a hearing disability by writing on paper. However, writing can be a bother and takes time. There are translation apps for overcoming language barriers, but all it usually does is display the translation on a screen.
In most cases, you are limited to a text-based means of expression.
Because spoken words appear as text along the line traced by your fingertip, the technology can be used easily by anyone.
By combining it with a multi-lingual translation function, a user can also communicate with people from other parts of the world.
