Usability and Design of WiFi Interstitial Pages

You’re out somewhere, maybe a coffee shop or an airport.  Suddenly, a man falls to the floor – you need to know – what’s the antidote for tricyclic antidepressants*?  You grab your laptop or mobile and use the local WiFi to look up the answer –

Only to be annoyed and inconvenienced by the interstitial “terms and conditions” page that the coffee shop and/or airport redirects your browser to.  Time is of the essence!  Why do they need a 2-minute flash animation to load an “I agree” button?

Thus ends my attempt to make a relatively boring subject seem interesting.  In any event, I can’t be the only person who’s noticed that WiFi login or “terms and conditions” pages are often way more complicated and annoying than they need to be.

In the hope that someone, somewhere will do a quick search before implementing one and come across this blog, here are some guidelines.  These all follow logically from supporting the user’s goal, which is to get info quickly, and the business’ goal, which is to attract and keep customers.

Do not require Flash, ActiveX, or god forbid Silverlight.  Nothing you could want to do here could possibly require it, and there are lots of WiFi-enabled mobile devices that don’t have it.  Do you really want to poke a finger in the eye of every customer with an iPhone?  If we’ve already bought iPhones,  we obviously like spending money!

Make the checkboxes / buttons large enough to click on a small device.  So that people with touchscreen PDAs, Blackberries, iPhones and G1’s will be able to touch it on their screens.

Make the page and any server-side code fast.  Stay out of the user’s way as much as possible.  If your code can’t accept a form and do some logging without dragging a user’s browsing session to a crawl, you need to go yell at your devs.

Once users agree to terms, save it in a cookie for a reasonable amount of time. Many mobile devices don’t allow programs to run in the background, which means session cookies can expire every time the device dozes off.

Once users agree, redirect them back to where they were trying to go.  And use a real, server-side http redirect too, not a fragile javascript redirect.  Many people set up their browsers to ignore those.

Make the legal terms and conditions as readable as possible.  Readability is an interesting topic, with lots of research into measurement formulas and the like.  I think we can all agree that an iframe with 1700 words of legalease is not readable or useful.  And while we’re at it, why not add some actually useful information, like bandwidth limits, disabled protocols, etc.  If you are blocking POP and IMAP, let me know so I don’t waste time trying to check my email.

While the crazy scenario at the beginning of the post isn’t very likely, this isn’t just a list of gripes.  Why are you providing WiFi if not as a service to customers or a way to differentiate?  Well, coffee shops with WiFi aren’t very unusual anymore, so you should look at it as part of the who customer experience.

* Why did I pick tricyclic antidepressants?  I did a Google search for poison antidotes and picked the first one with an antidote I thought you might be able to find, in a mad rush to save a beloved minor character’s life, like in a TV show.

EDIT:  thanks to Wysz for pointing out the massive numbers of typos.

Web-based genealogy software – any recommendations?

Desperation This past year we moved away from most of my family and added a new leaf to the family tree.  This has inevitably turned my thoughts to family history.  As expected from a guy who let the internet vote for his baby’s name and Twittered the delivery, I’m not going to be happy typing up a plain old document and mailing it out to family members.

I want to start collating a family history and collecting stories, photos, and other artifacts and I want to do it with a web app so that I can share with family spread all around the country.  Though I don’t have time for any hard-core genealogical research right now I’d like to set up a good framework in case anyone else in family catches the bug and finds themselves hunched over microfiche at the local LDS church.

So two of my main concerns are usability and openness.  Openness means having complete access and ownership of the data (so Facebook family tree apps are out) and compatibility with standard genealogical file types.

It would also me nice if it were written in a language I know like PHP, Java, or even Python in case I get the urge to write plugins or change the interface.

I know of two systems that might fit the bill, PhpGedView and GeneoTree, but I’m hoping to get some suggestions and recommendations before I start installing lots of stuff on my web server.  Has anyone done a project along these lines, or played around with this kind of software?

Bebo.com and Usable Social Networking Invite Systems

Upside-down Jellyfish for an upside-down invite system An apology to anyone who got an unwanted invite to social networking site Bebo.

I tend to join and try out a lot of social apps as I run into them. I was signing up for Bebo when I got to the part of the process where you add friends to your account. First I saw the section I wanted, “Friends found on Bebo who are in your address book:

Next, there’s a section, “Friends of friends on Bebo who you MAY know:” I started down this list but noticed many duplicates from the first list. Normally this kind of duplication is a minor usability issue, since it wastes some screen real estate and a small amount of user attention. But in this case the duplicates were so prevalent I scrolled back to the top and clicked the “Add Friends” button.

Had I kept scrolling, I would have seen the “Invite friends to Bebo from your address book:” section with every email address checked by default.

Every social networking site has a feature like this, and it fuels the exponential growth that some of these sites experience. But sending an in-site friend invite is very different from sending a email invite. Most of us have email contacts who fall into various categories – friends, co-workers, people we’ve bought stuff from, former bosses, friends’ parents, etc. Very few people would want to actually send out invites to every single email address in their address book, so that should never be the default behavior.

So, yeah, sorry for the Bebo invite spam.

In other news, I just sent out over 3300 emails to people who voted in the baby name poll and left their email address.
