Google launched a new mobile web service called Near Me Now that can recommend things like restaurants, bars and ATMs near you. This uses browser geolocation to provide only results relevant to where you are.

The idea is quite good: to replace business directories like Yelp or eat.fi with something that is easily accessible from Google's homepage and uses Google's great relevancy algorithms.

However, the implementation is not quite there yet. My main gripe is that they implemented this using browser sniffing so that the feature can be accessed only with iPhones and Android devices. Even though I'm using N900, a mobile device that has GPS and provides geolocation through the browser I cannot access that site. That reeks of the bad old times of IE-only websites.

Lesson: if you need browser sniffing to provide some feature, implement it based on browser capabilities, not the user agent (which can anyway be spoofed easily).

There certainly is a lot of buzz about Apple's rumored Tablet product. Daring Fireball writes:

If you’re thinking The Tablet is just a big iPhone, or just Apple’s take on the e-reader, or just a media player, or just anything, I say you’re thinking too small — the equivalent of thinking that the iPhone was going to be just a click wheel iPod that made phone calls. I think The Tablet is nothing short of Apple’s reconception of personal computing.

What I find most interesting are the view that the Tablet may bring new computer interaction paradigms. Again from Daring Fireball:

Our “desktop” computers’ human interfaces haven’t fundamentally changed since 1984 — keyboard and mouse/trackpad for input, overlapping draggable resizable windows on-screen, and a hierarchical file system where you create and manage “document files”. Have you ever sat back, scratched your chin, and wondered when the computer industry will break free of these current interfaces — which can be a hassle even for experts, and downright confusing (e.g. click vs. double-click) for the non-experts? Surely no one expects the computer interfaces of, say, 50 years hence to be based on these same metaphors and input methods. What’s the next step?

A touchscreen tablet isn't really suited for the WIMP paradigm as for example text entry is quite difficult, and you probably want larger, thumb-friendly user interface elements. This is where Microsoft's Tablet PC initiative failed, trying to bring the regular WIMP user interface to the tablet.

Instead what seems to be happening is that all the Wiis, iPhones, and N900s are now heading us towards a post-WIMP world. Instead of indirect manipulation by mouse and keyboard we can now interact with our applications using the more natural ways of touching things on screen or moving the device around.

This innovation will not be limited only to mobile APIs, web applications can already now know whether user is accessing them via a WIMP system or a touchscreen device thanks to CSS media queries and Javascript orientation events in latest Firefox.

The user interface innovation that is arriving thanks to these new interaction possibilities is quite promising, though it will probably take a while before we know what things actually work, and what are just fun demos.

If you're thinking about new kinds of user interfaces, it might be a good time to read papers like Noncommand User Interfaces (Jakob Nielsen, 1993) and Magic Ink (Bret Victor, 2006).

I certainly am as we are in the process of defining a new kind of CMS UI for Midgard 2.

Update: Gizmodo has a very nice article on Jef Raskin's information appliance concept and the evolution of GUIs.

Apple iPad is certainly interesting. It seeks to challenge the concept of PCs by providing something that is at the same time more personal, and a lot easier to use. The personal computer of the future.

Gone is difficult file organization - instead, applications use their own purpose-build content repositories. Instead of seeking software from many places, all of it is easily available in an App Store, all quality-controlled by Apple. And same thing with content - forget about bookshelves and stacks of CDs, instead simply dowloading all you need from iTunes.

This sort of user experience obviously comes with a cost. Important computing concepts like multitasking are not supported. The iTunes/App Store experience means that Apple is in the position to ensure no software or content competing with its or its business partners' business model gets on the device. And most of the content you buy for the device is DRM'd, meaning that you're only renting it for the time allowed by content owners, never buying.

Even with the limitations concerned I can see myself buying an iPad. It would serve as a very nice device for web surfing from the couch and as an e-reader on business trips. I can also see myself running demos and presentations from it instead of a laptop.

Even with the limitations concerned, it is likely that the iPad will happen, and will blaze the trail towards a new way of personal computing. Stephen Fry says it well:

Like the first iPhone, iPad 1.0 is a John the Baptist preparing the way of what is to come, but also like iPhone 1.0 (and Jokanaan himself too come to that) iPad 1.0 is still fantastic enough in its own right to be classed as a stunningly exciting object, one that you will want NOW and one that will not be matched this year by any company. In the future, when it has two cameras for fully featured video conferencing, GPS and who knows what else built in (1080 HD TV reception and recording and nano projection, for example) and when the iBook store has recorded its 100 millionth download and the thousands of accessories and peripherals that have invented uses for iPad that we simply can’t now imagine – when that has happened it will all have seemed so natural and inevitable that today’s nay-sayers and sceptics will have forgotten that they ever doubted its potential.

The success of iPad will mean more than just a completely new level of App Store economy. Other companies will certainly seek to emulate the model, coming up with their own post-WIMP devices and their own content and software ecosystems. This all will be a challenge for the free software movement.

The world of free software is still very much stuck in what computing was in the 90s. We think of desktop computers, we do not integrate with the web. And we do not get the transformation that is happening with personal computers. Taught by smartphones and cloud applications, users are moving from desktops through simple netbooks towards information appliances.

With information appliances you need a seamless user interface. You need an ecosystem where content comes alongside the software to utilize it. You need to move past the old WIMP metaphors and the idea of separation between data stored in a a file system and the software manipulating it.

So far the first convincing attempt towards this direction I've seen in the free software world is KDE's Social Desktop initiative. It allows users to connect with each other straight through the desktop, and it allows discovery of new applications and content to download and use straight in the applications. We also use it with Maemo's new App Downloader.

Threatened by the cloud from one end, and closed-ecosystem appliances from the other, it will be interesting to see how we react. Will we rise to the challenge and start providing new user experiences? Will we build a free cloud? Will we integrate with initiatives like Project Gutenberg and Creative Commons to provide the content integration? Will the open web be our safe haven?

Definitely interesting times to be a software developer.
