Google is working on a API for Digital Ink Recognition
Google is putting the final touches on a new API for digital ink recognition for Android and iOS. It will give developers the ability to create a new breed of apps where a stylus would be the the primary mode of interaction with the displays. This is not just going to be great for a new breed of writing tablets, but also give digital note taking devices that run E INK, an alternative to using a WACOM screen.
Digital Ink Recognition is different from the existing Vision and Natural Language APIs in ML Kit, as it takes neither text nor images as input. Instead, it looks at the user’s strokes on the screen and recognizes what they are writing or drawing.
