Course Finder update

October 20th, 2009
post #152 

Work on the Course Finder has increased, now it has been positively received. I’m now working to improve the usability even more, and ensure reliable data sources can be put in place, along with workflows to manage them.  Here’re some annotated shots of the current state of development.

First Load

The default view will load Undergraduate Courses, or the previously chosen award type if you’re returning from other pages. The Course List will be to view.

What you'll see on first load

Where previously A-Z Letter links would filter out non-matches, they now simply scroll down to the selected point in the alphabetised course list.

When the Course JSON file is first loaded, and on each subsequent load, checks are performed to see which letter of the alphabet is not represented (we have few courses beginning with ‘K’, for example), and those letters are greyed out.

As you Type Filtering & Highlighting

As planned typing in the box filters the Course List. Now a message appears reporting on the number of courses visible compared to the total count. Clicking the ‘X’ in the field will clear it, and restore the full list. Clicking an A-Z letter will restore the full list and scroll as required.

As you type, the part of the Course Title where your phrase appears is highlighted in the text.

Inline Search Results

This feature has been a long time coming. Search results are loaded via an XML-to-JSON filter script adapted to limit the search to the selected award. Title, relevance score and a basic summary are displayed. The JSON data contains everything needed to paginate the results, a feature that will follow. The script returns the data within an XJSON header which is then parsed into place on the page.

Showing Course search results gives rise to layout issues: where to put the Course listings and how to differentiate between them. Sub-tabbing was one option which was discarded, and in the end the choice was to shift the Course listings down the screen and to put Search results in their place, with a button to close them and restore the prior layout.

Search results use an alternate list style too, to highlight the expanded information available.

Switching to another Award Type hides (gently…) any visible Search results and restores the default listings view, loading the appropriate set of Courses.

Here’s the Iphone & Touch version of the newly spruced Course Finder. The function is far more simple than the conventional web version, just select your award and then locate a course from the list.

The labelled buttons and alphabetical list format closely mirrors the Iphone’s internal layouts. The latter was achieved quickly using the excellent Contact List on Webkit package from cubiq.org.

For this project to be adopted it will need to be presented with full corporate branding. Something I have thus far steered clear of. However, the greater task of search integration is my next priority.

Here’s the presentable, standalone variant of the demonstration Course Finder I showed at BathCamp.

note: Compatibility View required for IE8, I’m working to fix this now.

It’s probably best viewed on this project’s category page.

Tested in a handful of browsers including IE8, Firefox, Chrom and Opera.

The Iphone demo web application will follow shortly.

Planting courses in the Guerrilla Garden

Prototype growing nicely

Here’re some screens of the new AJAX driven course finder. I’ll shortly add a hosted example but in the meantime the screens are sufficient to discuss some of the observations made now that development has begun.

First load

A-Z Links – filtration and index

4coursefinder_byfirstletter

It became apparent quickly that having the A-Z links work the same as the Search Field (filtering by word beginning) could be confusing. For example with 5 Courses to view, a word-beginning filtration could show 5 courses who’s titles begin with A.

So the A-Z links operate as before, they filter purely on title starting letter.

I intend to change this however, from a filter that removes non-matches to a scroll mechanism: rolling the full Course List down to the starting letter, not unlike a thumb-tab in an address book.

Search Field Filtration

3coursefinder_searchfilter_

Typing in the Search Field removes any course that doesn’t contain the words being typed. It’s rudimentary right now, filtering only on complete phrases starting with word-beginnings, but the quantity of content being dealt with, and the nature of the search requirements could mean that this is lightweight approach could suffice.

Initial testing with a single volunteer was positive.

The … Iphone

The layout used for prototyping is deliberately flexible to cater for varying screen sizes and devices. Overall the layout worked well on the smaller screen, of course buttons sizes will need to be increased for SSDD users.

I had to test the initial offering on a device, and had made an oversight I won’t be repeating. Using the onscreen keyboard obscures the dynamically updating list of courses, until you click the ‘done’ button. Additionally, autocomplete was trying to make a word on my behalf when all I wanted was the first few letters to narrow my results.

The on-screen keyboard renders the dynamic as-you-type filter useless until you've finished typing

For mobile devices then providing just the A-Z Links will be a faster mechanism, and we can save the overhead of the periodic updater routine for those users too.

JS/DOM event handling

At present no controls are placed on the tabs aside from firing the AJAX requests, but the actions in the Search Fields and A-Z Links are mutually exclusive, especially with the periodic updater running, so require additional safety measures.

Clicking an A-Z Link disables the periodic updater. Actions in the Search Field restore the periodic updater and reset the visual state of the A-Z Links.

What’s Next

A live working example, more on the mobile usage, and a little user-acceptance testing.

Guerilla Gardening, day three – UI refinement

Got content.  Got concept.

On day one I had a rough plan of how to make the improvements to the Courses UI.

The various search, A-Z and listing interfaces, combined

The various search, A-Z and listing interfaces, combined

How it’ll work

The pencil sketch above is a fair representation of my plan – each Course Type available is clearly visible near the top of the view. The Undergraduate courses tab is activated by default, and the full list of clickable Undergraduate Course titles appears in the ‘results’ box below.

Switching tabs loads the Course listings for that Course Type into the results box, and the A-Z and Search box now operate on the new listings.

Typing into the Search input box filters the current listings by the phrase you’re typing, but if you click ’search’, you are taken to the search page and your query results are shown (I’ll return to this later).

In the absence of Javascript, the interface should be split back into the sequential copies of the A-Z links per Course Type, the way it appears now, and all functionality back to basics.

Refining the proposed UI

Looking at the diagram, I wonder how I’ll fit a whole alphabet in the space, alongside a search box and submit button. I may have to sacrifice the  scant advantage it brings in order to make the page easier to understand.

However the A-Z links are a feature of the page as it now stands, so will be part of the original and non-javascript views at the very least. I could perhaps make the options (re-) appear when a control is moused over or clicked. For the moment the feature will be developed whether or not it makes it to the final cut.

As-you-type Course Filtering

If retained, the A-Z links will act as shortcuts to the filtering action of the Search input box. This will be an improvement over their current action, which returns pages of links based on the first letter of the course title.

Right now, clicking on ‘A‘ will give you Applied Psychology, but not History of Art and Museum Studies.

The javascript filtering should instead detect the chosen letter at both the string and word beginnings. Clicking on ‘A’  would give you Nursing BA – Adult, Graphic Arts and Pharmaceutical Analysis.

It will also include every course with ‘and‘ in it, so some common word exclusion will be necessary too.

Returning Search results

Right now Search results are displayed in the Search context – our query takes you away from the current page to the search server and a web page is generated to show results. This new scheme’s aim is to keep navigation within the Course Area, retaining appropriate navigation.

Using the Search facility’s API, the results should be retrieved as XML, parsed and formatted then shown in the same Course listings ‘results’. This means we’ll need to highlight the difference between search results and Course listings.

The next stage will be getting some working examples going. First though I’ll need to note the order of the dynamic events incorrect rendering of the tabs and results.

Order of events in the JS driven UI

The page hinges on the Course Type, so switching Course Type can trigger resets of other elements such as the text in the search area. It’s probably best to clear the results area too – in readiness for new AJAX loaded data, and allowing the visual change in the tab from inactive to active to occur only on successful load of that data – otherwise network issues could result in a very confused page.

In addition to the clickable events, there’s the periodic routine checking the contents of the Search box and filtering the list accordingly.

I’ve tried to anticipate what should happen along with each event below:

Event reactions
Tab Selection
Active tab No action.
Inactive tab Disable A-Z links, disable periodic Search box routine, clear Search and results areas, display loading message/icon, load data into results area, use signal in results to switch to make tab active, make others inactive, re-activate A-Z links and periodic Search box routine, clear loading message, displaymessage/icon to denote listing type as ‘Courses’.
A-Z link click Replace content of Search box with selected letter. Start the periodic search box routine.
Search box focus Start the periodic search box routine.
Periodic Search box routine Take contents, format for filtering (remove common words and inappropriate characters), set the display of matching/non-matching courses appropriately.
Search Submit box click Disable A-Z links, ‘fade’ A-Z links buttons to show they’re not available in this context, disable periodic Search box routine, clear results area, load data into results area, use signal in results to switch to display message/icon to denote listing type as ‘Search Results’.

That’s enough forward planning for the moment. It’s time to start prototyping.

Adapting the Course page content

Any hopes of getting hold of a clean and complete data source of every course’s details were soon dashed. The CMS – which of course thinks in pages in most instances. This is great as it makes updates and devolving of content submission far easier, but I need to work around it.

Title, URL, and Course Type

The CMS will easily give up Course Title and URL, but accessing award, availability for clearing and other attributes of the pages would require far more work, possibly HTTP spidering.

The structure we gave to the Courses area when last reworked thankfully lends itself well to grabbing these additional attributes -  denoted by their publication. Each of the three Course Types are published to a location determined by its award type:

<site root>/courses/undergraduate/

<site root>/courses/postgraduate/

<site root>/courses/cpd/

With a new templated page in the CMS connected to the content of the Course pages,  I can quickly generate a rough data source for Course Title and URL into a list. I can bypass the Compliance and tidy management tools for the template, allowing me to make whatever document format I need from the source.

Availability for Clearing

For a short time each year the Clearing attribute comes into play. The courses available for Clearing are a subset of undergraduate courses, created by adding an attribute to each page.

Another great feature of the CMS is keyword assignment, which allows pages to be aggregated into lists of links and titlesfor use elsewhere.

Keyword assignment list creation in the CMS

Keyword assignment list creation in the CMS

The Clearing keyword allows me to create such a list, giving me my final data source.

For the moment I’ll leave each output page as a simple HTML list of the format:

<ul>
  <li><a href="courseurl_1">Course Name 1 <a/></li>
  <li><a href="courseurl_2">Course Name 2 <a/></li>
</ul>

With a snapshot of data output to files, I can begin to put together some of the proposed components. An added bonus here is that my simple data sources have by necessity been separated by Course Type, which is no bad thing as that’s the fisrt fork in the road for most visitors to the Courses pages.

With luck, more tomorrow.

Guerilla Gardening, day one

Plot Chosen. The Courses area.

View the category Guerrilla Gardening for the full story

It’s a high traffic part of the site presenting probably the most important pre-application content we have.  Over the years it’s had gradual improvements, most notably a modified mooTools accordion feature to accommodate the various Course Types in easily identified compartments which open and close with a click.

The page content is fully accessible without Javascript, and is fine for screen readers.

By Default all accordion boxes are closed, except the Search All Courses box

The Course Page

The purpose of the page is – unsurprisingly – to effectively get a prospective applicant to the course or courses that interest them, it should be so usable, you don’t even know how you arrived at the course you came for.

When first loaded four compartments are visible, with Undergraduate courses, Postgraduate courses and CPD (Continuing Professional Development) all represented in a closed state.

By default the bottom box is open, providing a course search facility.

The Undergraduate Section open, showing the A-Z Listings links

Opening any Course Type shows a clickable alphabet, clicking on the letter ‘A’ in Undergraduate takes you to the undergraduate ‘A’ Listings page.

While only one set of A-Z links  is ever visible, there are three sets of Alphabetised links embedded in the page.

The Course Search does not filter by Course Type as the alphabetised links do. As it employs the website-wide search facility, it temporarily navigates the user away from the courses area to display search results within the usual search page,  related side links, which makes return navigation problematic.

A typical use case involving searching for multiple courses might take a user across two pages before reaching the course page and the a single return step to the Courses Home.

The (Rough) Plan

Rough Draft of the proposed layout

Rough Draft of the proposed layout

Off the top of my head, I’d like to:

  • remove the repeating elements presented on the page
  • develop a dynamic single-view for all courses, with minimal clicks or page loads
  • keep the search results within the Courses part of the site
  • show links to courses from the outset, with no A-Z pages required
  • Maintain the usual editing and update regime via the CMS
  • Maintain accessibility

Whether or not it results in a deployable application doesn’t yet concern me so much as the steps necessary to achieve it – which in themselves will be useful later on.

As all the information resides in the Content Management System or its published pages, the first steps involve overcoming retrieval and formatting.

For starters I’ll need to:

  • Adapt the current Courses area content into some sort of re-usable data source
  • Use the data sources to populate an easy-to-use course selector
  • Justify my own time by developing some ideas for re-using the data elsewhere
