Regards appreciated friend @jjqf.

I cannot deny that this topic you addressed immediately caught my attention. All the actions that are developed with the intention of improving the quality of life of the people, are involved with a great feeling of nobility and humanity.

With your explanation it was not clear to me how the process would be, or rather how the device that people with disabilities would use to write would be. I suppose they should use an optical pencil so that an automated system with AI support interprets the "scribbles" drawn and then represents them with the corresponding letter on the screen of a computer or device.

Great topic, thanks for sharing.

Your friend, Juan.
