As mobile UE designers, we face a constant challenge - how to offer our users lots of great features without creating a complex experience for them?

Within our team, we talk often about the experience we want to create - as people use our service for the first, second and future times. We work to create an experience where features are ‘revealed’ to users as they choose. We want this to happen progressively over time, so the user deepens their experience with the service under their own control.

Rather than purely taking in consideration what features to include in the service - which is what Kathy Sierra refers to in her Featuritis Curve below - we look at how the features could be unveiled so that the first visit isn’t overwhelming! On a mobile phone in particular, where we face constraints of limited screen space, network latency and navigation, it’s crucial that we fight the urge to tell a user everything at once.

Some users just want a simple search experience. Others will want to share what they find with friends by SMS. Others will want to broadcast a link to all their friends - direct to their favourite social network or microblog feed, (i.e. Twitter). We need to consider every one of those scenarios when designing.

For the first time user, our service is clearly a mobile search engine. We keep it simple and don’t offer stacks of features that will overload them either onscreen or cognitively. As users explore the service, they can discover other features - or ignore them - as they wish.

There is a concept in User Interface (UI) design called progressive disclosure, which Jakob Nielsen referred to in 2006.

A classic example of progressive disclosure in computer software is the ‘Print’ dialog box displayed when printing a document. First, you’ll see the dialog which shows only a few important options. If you want to, you can also ‘disclose’ a whole range of other settings/controls - the ‘advanced mode’ - peeling away at the layers of the onion until you get to what you need.

As a concept, progressive disclosure is similar to what we’re trying to achieve with the user experience of Taptu. We want this approach not only to work at individual widgets level, but to underpin the whole service experience as it unfolds to our users.

Have you used a service that gave you this feeling of revealing features? Or one that utterly failed at it by either overloading or hiding them too far away? We’d love to hear more about any you think do it well, or not so well!

We’re excited and honoured to have been selected by Red Herring as one of the Top 100 European Tech Startups this year.

Past winners have included some of the most successful and innovative companies out there, such as Google, YouTube, Skype and Netscape, and the Top 100 falls under the theme “Europe 08: Ahead of the Curve”, so it’s great to be included in such hot company!

Following the warm reception we received at Mobile World Congress in February, where we received the Mobile Monday Peer Award’s Community vote in the Emerging Startups category, we’re very grateful for the recognition our users and industry colleagues have given us.

The Red Herring site contains the full list of companies in the Top 100.

This week’s Carnival of the Mobilists is hosted by Debi Jones at MobileJones and contains a bumper crop of posts from all around the world and on a variety of topics; Handset companies, former handset companies, Internet companies, new entrants and social networking giants are all involved in mashups of services.

Have a look for a good roundup of this week’s mobile news.

On Monday night, a few members of the Taptu squad attended MoMo London where Steve presented, talking about user interface design and the process through which we develop it. Some of you have asked for a copy of the slides we used, so here they are. (Tip: Set the presentation to fullscreen if any of it goes a bit fuzzy)

For more multimedia of the evening, check out Alex Craxton’s blog for the nerdiest sword fight you’ll ever see!

This morning, The Register reports O2’s admission that its 3G customers are limited to 128Kb/s connections - with some business users being upgraded as O2 sees fit.

“384Kb/s is the technical limit of 3G technology, without resorting to HSPDA, but topping out at 128Kb/s is something of an embarrassment for a 3G network. Not that using HSDPA will help the O2 customer, depending on the “profile” O2 has decided to assign to them they might still find themselves allocated only 128Kb/sec”, says El Reg.

In non-techy terms, this means that you’re buying a 3G phone, with the expectation of fast mobile web browsing, but in fact, you’re being limited to half the potential speed you should get.

A clever fella from the 3G.co.uk forum did a speed test on the network, getting the following speeds:

GPRS 44kbit/sec
EDGE 145kbit/sec
3G 112kbit/sec
HSDPA 124kbit/sec

I tried the tests a few times and posted the fastest. The 3G and HSDPA speeds are consistently around the times posted. The EDGE speeds were more variable, from 90 to 145kbit/sec I assume depending on cell traffic at the time.

Is it just me, or are customers not getting at all what O2 is claiming. It’s supposed to be 3G, and it ain’t doing what it says on the tin!

Granted, I’ve got an iPhone, I wouldn’t get 3G speeds anyways, but I do feel sorry for the cheeky sods who’ve been giving me a tough time for having a non-3G phone. I’m currently getting better speeds than you are if you’re also on O2!

Now, immature raspberry-blowing aside, I do hope O2 get their act together and allow non-business users to experience the full potential the network has to offer. This is a stick in the wheels of the mobile web we simply do not need.

[Update: Seems like O2 are set on making an impression on their customer base today. Did you know we’re “a bunch of geeks” and would be “muppets” for considering changing networks? Well, it seems too funny to be true, but O2 PR staff may need some coaching on locking their phone before having private conversations.

Did you hear that? Yes, it’s the sound of two PR people who are going to have a very bad end of Wednesday…]

On the heels of CTIA in Las Vegas, Mobile Point View hosts the first April Carnival of the Mobilists.

Chetan Sharma writes a roundup of CTIA for those of us who didn’t attend, Michael Mace posts a rather humourous survey conducted by Rubicon Consulting on things you didn’t know about iPhone owners, and I contributed our entry on 20 resources for mobile designers and developers.

The odds are in your favour, you’ll find some great content in this week’s contributions.

Yesterday, we sneaked out the latest version of Taptu when you weren’t looking.

Mainly, we released a new version which caters better to low end phones. Some phones, like Motorola RAZRs and previous generations of Sony Ericssons need smaller, simpler pages, tweaked for their limitations. Every time you access Taptu, we detect what mobile phone you’re using and give you the version of the service that will provide the best experience. What’s the point of sending the high end version to your phone if it’s going to crash your browser?

We’ve also released a metric ton of bug fixes and tiny tweaks to improve the service, some of them based on bug reports you’ve sent in - so thank you all for your useful feedback, your comments never go unheard!

*Shifty look around for the boss* I’m not supposed to be telling you this, but we’ve also released a few extra small features, which are very beta. Shh! You’ll just have to go play around with the service to find those out for yourself…

Yesterday, I blogged about T-Mobile’s poor decision to ask Engadget Mobile to remove all traces of magenta from its branding. As Stan from Mashable says, “how, exactly, did the T’s lawyers and PR folks think Engadget will react? Humbly remove all traces of magenta from their site, issuing a big ole apology? If they did, they were wrong.”

I bow down to Engadget’s creative response. Note the header changes:

Here at Taptu, you might have noticed we’re very fond of the colour pink. We haven’t received a letter from T-Mobile, but we’ll be happy to tell them where to go if we ever do!

Join Engadget’s solidarity campaign by going pink for the day, like GearBits, Josiah Miller and Joshua Topolsky.
