wanda

Wanda is a Javascript gesture recognition library based on the $P recognizer. It's written with the UMD pattern, so it can be used anywhere.

Usage

npm install --save wanda

Then, in your codebase,

import Wanda from 'wanda';

const wanda = new Wanda();

wanda.train(id, data);

const result = wanda.recognize(data);

API

Wanda.train(id, data)

Add training data to wanda. id is a string identifier for the data. data is an array of strokes, where a stroke is an array of points. It will look something like this:

[
  [{x: 30, y: 146}, {x: 106, y: 222}], // stroke 1
  [{x: 30, y: 225}, {x: 106, y: 146}] // stroke 2
]

Wanda.recognize(data)

Recognize a gesture. data is an array of strokes, where a stroke is an array of points, the same as described above. This method will return a result that looks like the following:

{
  id: '<result id>',
  score: <confidence>
}
