Description

The identityfusion module turns an HTML input into an interactive widget that administers the Dynamic Identity Fusion Index (DIFI) [1], which assesses the degree to which the user's own identity fuses with a group identity. The widget consists of a circle labeled "Me" which can be dragged or moved using buttons to overlap a circle which represents the group.

Two values are recorded:

1. Distance
2. Overlap

Usage

To use the widget, create an HTML input with a name:

<input name="DIFI" id="DIFI" />

Then include the library and create a new DIFIInput instance:

<script src="identityfusion.js"></script>
<script>
  var el = document.getElementById('DIFI');
  new identityfusion.DIFIInput(el, {
    groupLabel: 'USA'
  });
</script>

Instantiating the DIFIInput will replace the original input with two hidden inputs named DIFI_distance and DIFI_overlap (with the original name as the prefix).

See dist/demo.html for an example.

Options

Several options can be specified in the second parameter when constructing a DIFIInput:

• meLabel: The label for the circle representing the user. (Default: Me)
• groupLabel: The label for the circle representing the group. (Default: Group)
• groupImage: URL for an image to be shown as the background of the group circle. (Default: none)
