Project Summary

Summary

Add a feature to allow administrators to create and share walkthroughs, which are a series of instructional overlays displayed on top of the Moodle User Interface.

Problem

Moodle is a large application with many features. Some of these features are hard to understand without instruction. One on one training for Moodle is time consuming and hard to scale.

Solution

Allow the administrator to create "walkthroughs" where a series of instructional overlays are displayed over the Moodle User Interface.

These are also often known as:

• instructional overlays; and
• tours.

Target Users

Administrators, New Moodle users, Experienced Moodle users exposed to a new feature, Teachers, Students

Technical Requirements

• Simple clear overlays that are easy to disable or replay
• Import/export walkthroughs to a simple file format so they can be shared
• Themable
• WCAG AA compliant
• Full support for RTL
• Full support for Multilang

Proposed solution

• An admin tool plugin to create, and manage, user tours;
• Integration with an external overlay library;
• library wrapped in a moodle-specific AMD module for loading;
• theme-specific step template to be passed to the library;
• string translations to be passed to the library.

External integrations

Several external instructional overlay libraries already exist. These are JavaScript libraries which take configuration (usually JSON) and produce tours to display to end users.

The following base requirements were considered for the library:

• WCAG AA compliance
• Support for string translations
• Support for LTR/RTL switching
• Ability to modify the template used for step display
• Ability to store state at any point
• Responsiveness
• Ease of theming
• JS requirements

Of the libraries considered only a handful come close to meeting our requirements and none actually met all of the requirements.

For the contrib version of the plugin currently available (local_usertours), the bootstrap-tour library is in use, but this is too tightly integrated with the Bootstrap 2.2 JavaScript.

After careful consideration it was felt that writing a new library for these tours may be the best, and most flexible solution and that this could be released back to the community.

hopscotch

Hopscotch is an Instructional Overlay written and maintained by LinkedIn.

Features

• event callbacks
• multi-page tours
• i8n support
• lightweight
• flexible templates
• flexible placement
• flexible targetting
• range of tour and step options

Benefits

• does not rely upon any external libraries, though it can utilise jQuery if it is present on the page
• handles its own styling, and positioning
• HTML5 session storage
• wide range of events fired to allow additional customisations

Concerns

• lack of responsive design. Steps are displayed off-screen on mobile devices
• lack of accessibility
• difficult to customise

Although a number of events and customisation points are available, the library makes it difficult to utilise these. You can override the renderer, but are then unable to access the internal functions of the tour.
