Creatability Accessible Web Components

in active development

Creatability is a set of experiments made in collaboration with creators and allies in the accessibility community. They explore how creative tools – drawing, music, and more – can be made more accessible using web and AI technology. We hope they inspire others to make new projects, so we've started open-sourcing components here for anyone to use. Note this repo is under development. Contributions welcome!

Setup an Input

A simple example of toggling between mouse/keyboard and body tracking input.

<acc-input-mode-select oninput="onInput">
    <acc-mouse-input amplification="10"></acc-mouse-input>
    <acc-pose-input smoothing="0.5" selected></acc-pose-input>
</acc-input-mode-select>

<script>
    function onInput(event){
        const input = event.target;
        //position is normalized from -1, 1
        const x = input.position[0];
        const y = input.position[1];
    }
</script>

the simplest example of using this purely in javascript

const input = document.createElement('acc-pose-input');
//or use document.querySelector('acc-pose-input')

input.addEventListener('input', (event)=>{
    console.log(event.target.position);
});

//this triggers the loading and initialization of any resources
input.initialize();

You can of course bind the event the same way with javascript:

const inputSelector = document.querySelector('acc-input-mode-select');

inputSelector.addEventListener('input', (event)=>{
    console.log(event.target.position);
});

Input Event Cycle

All input types dispatch the following events:

• 'initializing' when the input begins to load and initialize any necessary resources.
• 'ready' when the input has completed initializing and is now operating
• 'input' dispatched every time the input has a new value
• 'stop' dispatched if the input has stopped such as by switching inputs or calling input.stop().
• 'change' dispatched when an attribute/property changes values

Input methods

All Input types contain the following methods:

• input.initialize() required to begin using the input
• input.stop() can be used to stop the input

Tutorial

The tutorial element gives you a simple slide show. It extends AbstractModal so it can be added to the screen by adding an "open" attribute. Each of the <acc-slide> children will be rendered as a slide-show.

<acc-tutorial>
    <acc-slide
        video="assets/s1.mp4"
        alt="don't forget to add alt text for the video"
        caption="This experiment lets you combine speech and music in a fun way."></acc-slide>
    <acc-slide
        caption="Just type some words, then set them into your own melody."
        video="assets/s2.mp4"></acc-slide>
    <acc-slide
        caption="You can change the melody using your mouse or keyboard."
        video="assets/s3.mp4"></acc-slide>
    <acc-slide
        caption="Just play around – try different voices, scales, and more."
        video="assets/s4.mp4"></acc-slide>
</acc-tutorial>
