A Digital Exhibits Epic Saga: Game of Stones

A screen from the Queering Duke History exhibit kiosk, just one of the ways DigEx supports library exhibits.

Just under a year ago Duke University Libraries formed the Digital Exhibits Working Group (DigEx) to provide vision, consulting expertise, and hands-on support to the wide array of projects and initiatives related to gallery exhibits, web exhibits, data visualizations, digital collections, and digital signage.  Membership in the group is as cross-departmental as the projects they support. With representatives from Data and Visualization, Digital Projects and Production Services, Digital Scholarship Services, Communications, Exhibits, Core Services and the Rubenstein Library, every meeting is a vibrant mix of people, ideas and agenda items.

The group has taken on a number of ambitious projects; one of which is to identify and understand digital exhibits publishing platforms in the library (we are talking about screens here).   Since April, a sub-committee – or “super committee” as we like to call ourselves – of DigEx members have been meeting to curate a digital exhibit for the Link Media Wall.  DigEx members have anecdotal evidence that our colleagues want to program content for the wall, but have not been able to successfully do so in the past.  DigEx super committee to the rescue!

The Link super committee started meeting in April, and at first we thought our goals were simple and clear.  In curating an exhibit for the link wall we wanted to create a process and template for other colleagues to follow.  We quickly chose an exhibit topic: the construction of West Campus in 1927-1932 told through the University Archive’s construction photography digital collection and Flickr feed.  The topic is both relevant given all the West campus construction happening currently, and would allow us to tell a visually compelling story with both digitized historic photographs and opportunities for visualizations (maps, timelines, etc).

Our first challenge arose with the idea of templating.  Talking through ideas and our own experiences, we realized that creating a design template would hinder creative efforts and could potentially lead to an unattractive visual experience for our patrons.  Think Microsoft PowerPoint templates; do you really want to see something like that spread across 18 digital panels? So even though we had hoped that our exhibit could scale to other curators, we let go of the idea of a template.

 

We had logistical challenges too.  How do we design for such a large display like the media wall?  How do you create an exhibit that is eye catching enough to catch attention, simple enough for someone to understand as they are walking by yet moves through content slowly enough that someone could stop and really study the images?  How do we account for the lines between each separate display and avoid breaking up text or images?  How do we effectively layout our content on our 13-15” laptops when the final project is going to be 9 FEET long?!!  You can imagine that our process became de-railed at times.

Stone was carried from the quarry in Hillsborough to campus by way of a special railroad track.

But we didn’t earn the name super committee for nothing.  The Link media wall coordinator met with us early on to help solve some of our challenges. Meeting with him and bringing in our DigEx developer representative really jumpstarted the content creation process.  Using a scaled down grid version of the media wall, we started creating simple story boards in Powerpoint.  We worked together to pick a consistent layout each team member would follow, and then we divided the work of finding images, and creating visualizations.  Our layout includes the exhibit title, a map and a caption on every screen to ground the viewer in what they are seeing no matter where they come into the slideshow. We also came up with guidelines as to how quickly the images would change.

At this point, we have handed our storyboards to our digital projects developer and he is creating the final exhibit using HTML and web socket technology to make it interactive (see design mockup above). We are also finishing up an intro slide for the exhibit.   Once the exhibit is finished, we will review our process and put together guidelines for other colleagues in DUL to follow.  In this way we hope to meet our goal of making visual technology in the library more available to our innovative staff and exhibits program.   We hope to premiere the digital exhibit on the Link Wall before the end of the calendar year.  Stay Tuned!!

Anatomy of an Exhibit Kiosk

I’ve had the pleasure of working on several exhibit kiosks during my time at the library. Most of them have been simple in their functionality, but we’re hoping to push some boundaries and get more creative in the future. Most recently, I’ve been working on building a kiosk for the Queering Duke History: Understanding the LGBTQ Experience at Duke and Beyond exhibit. It highlights oral history interviews with six former Duke students. This particular kiosk example isn’t very complicated, but I thought it would be fun to outline how it’s put together.

Hardware

Most of our exhibits run on one of two late 2009 27″ iMacs that we have at our disposal. The displays are high-res (1920×1080) and vivid, the built-in speakers sound fine, and the processors are strong enough to display multimedia content without any trouble. Sometimes we use the kiosk machines to loop video content, so there’s no user interaction required. With this latest iteration, as users will be able to select audio files for playback, we’ll need to provide a mouse. We do our best to secure them to our kiosk stand, and in my tenure we’ve not had any problems. But I understand in the past that sometimes input devices have been damaged or gone missing. As we migrate to touch-screen machines in the future these sorts of issues won’t be a problem.

Software

We tend to leave our kiosk machines out in the open in public spaces. If the machine isn’t sufficiently locked down, it can lead to it being used for purposes other than what we have in mind. Our approach is to setup a user account that has very narrow privileges and set it as the default login (so when the machine starts up it boots into our ‘kiosk’ account). In OS X you can setup user permissions, startup programs, and other settings via ‘Users and Groups’ in the System Preferences. We also setup power saving settings so that the computer will sleep between midnight and 6:00am using the Energy Saving Scheduler.

My general approach for interactive content is to build web pages, host them externally, and load them on to the kiosk in a web browser. I think the biggest benefits of this approach are that we can make updates without having to take down the kiosk and also track user interactions using Google analytics. However, there are drawbacks as well. We need to ensure that we have reliable network connectivity, which can be a challenge sometimes. By placing the machine online, we also add to the risk that it can be used for purposes other than what we intend. So in order to lock things down even more, we utilize xStand to display our interactive content. It allows for full screen browsing without any GUI chrome, black-listing and/or white-listing sites, and most importantly, it restarts automatically after a crash. In my experience it’s worked very well.

User Interface

This particular exhibit kiosk has only one real mission – to enable users to listen to a series of audio clips. As such, the UI is very simple. The first component is a looping ‘attract’ screen. The attract screen serves the dual purpose of drawing attention to the kiosk and keeping pixels from getting burned in on the display. For this kiosk I’m looping a short mp4 video file. The video container is wrapped in a link and when it’s clicked a javscript hides the video and displays the content div.

 

The content area of the page is very simple – there are a group of images that can be clicked on. When they are, a lightbox window (I like Fancy Box) pops up that holds the relevant audio clips. I’m using simple html5 audio playback controls to stream the mp3 files.

Finally, there’s another javascript running in the background that detects and user input. After 10 minutes of inactivity, the page reloads which brings back the attract screen.
