chenyuho / handwriting.js Goto Github PK

Hello,

We (Chrome and Chrome OS) are working on a standardized Web API for handwriting recognition. The proposal is here: explainer.

The API would allow websites to access handwriting recognizers that's locally available on device (instead of sending the requests to cloud servers). It's currently implemented on Chrome OS (backed by the same technology used in IMEs).

Does the API interest you?

We'd also like to hear your feedback and make it easier to integrate with your library.

I will be teaching some children how to write their first words and this script is exactly what I was looking for.

Thank you so much!

Quick question: How to change the pen or ink color from black (current color) to white?

Thanks

Hi Chen,

I am getting a strange error.
While using the script on mobile I get the following error in console.

[Violation] Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as
[Violation] Added non-passive event listener to a scroll-blocking 'touchmove' event. Consider marking event handler as

This is on line 38 and 38 of the handwriting.canvas.js

Love the project by the way!
Great learning resources.

Currently, if you just click in the canvas, it doesn't write anything. I would like to be able to write the dot for an "i" or a "j" with a simple click

I dont get how we capture a trace

Currently, handwriting.js only POSTs to one service endpoint, that is https://www.google.com.tw/inputtools/request?ime=handwriting&app=mobilesearch&cs=1&oe=UTF-8. I propose that we add alternative service endpoint URLs which the user could pick from. This will reduce the load off Google's servers, and will circumvent (or at least alleviate the restrictions of) Google's API usage limits.

Here are the possible alternative service endpoint URLs the could choose from:

let serviceEndpointURLs = {
    "default": "https://www.google.com.tw/inputtools/request?ime=handwriting&app=mobilesearch&cs=1&oe=UTF-8",
    "google_tw": "https://www.google.com.tw/inputtools/request?ime=handwriting",
    "google_jp": "https://www.google.co.jp/inputtools/request?ime=handwriting",
    "google": "https://www.google.com/inputtools/request?ime=handwriting",
    "inputtools": "https://inputtools.google.com/request?ime=handwriting"
}

I will try to create a pull request to day to implement these. What do you think?
