function inferInputModel() {

    if (window.navigator.msPointerEnabled) {
        return 'pointer';
    } else if (window.ontouchstart !== undefined) {
        return 'touch';

    case 'pointer':
        element.addEventListener('MSPointerDown', msStart);
        element.addEventListener('MSPointerOut', msStop);
        document.addEventListener('MSPointerUp', msStop);
        document.addEventListener('MSPointerCancel', msStop);
        document.addEventListener('MSHoldVisual', preventDefault);
        break;

    case 'touch':
        element.addEventListener('touchstart', touchStart);

        element.addEventListener('mousedown', mouseStart);
        element.addEventListener('mouseout', mouseStop);
        document.addEventListener('mouseup', mouseStop);
        break;

    default:
        element.addEventListener('mousedown', mouseStart);
        element.addEventListener('mouseout', mouseStop);
        document.addEventListener('mouseup', mouseStop);
        break;
}

Please give an Example how to implement these !
