ios.js is JavaScript implementation of the Inclusion of Other in the Self (IOS) scale that satisfies its original design features.

It is available on GitHub.

Continuous IOS scale

Proportion overlap:

Proportion distance:

HTML:

<div id="ios-continuous"></div>
Proportion overlap: <span id="continuous-ios-overlap"></span>
Proportion distance: <span id="continuous-ios-distance"></span>

JS:

const iosContinuous = new Ios({el: 'ios-continuous'});

const continuous_ios_distance_input = document.getElementById('continuous-ios-distance');
const continuous_ios_overlap_input = document.getElementById('continuous-ios-overlap');

document.getElementById('ios-continuous').addEventListener(
    'mousedown',
    () => {
        window.addEventListener(
            'mouseup',
            () => {
                continuous_ios_distance_input.innerHTML = iosContinuous.proportionDistance;
                continuous_ios_overlap_input.innerHTML = iosContinuous.proportionOverlap;
            },
            false)
    }, false

Original IOS scale

Proportion overlap:

Proportion distance:

HTML:

<div id="ios-original"></div>
IOS score: <span id="original-ios-score"></span>
Proportion overlap: <span id="original-ios-overlap"></span>
Proportion distance: <span id="original-ios-distance"></span>

JS:

const iosOriginal = new Ios({
    el: 'ios-original',

const original_ios_score_input = document.getElementById('original-ios-score');

document.getElementById('ios-original').addEventListener(

        window.addEventListener(
            'mouseup',
            () => {

            },
            false)
    }, false
);

Extended IOS scales

As we explain in our documentation, ios.js offers two options to extend the discrete IOS scales by adding intermediate circles. The unbalanced option adds circles in the first half of the scale, while an option inspired by the IOS11 of Baader, Starmer, Tufano, G├Ąchter adds intermediate circles in the first and the last third of the scale.
