The pace of change has become blisteringly fast, with traditional industries -- bookstores, video-rental chains, newspapers -- crumbling more quickly than we could have imagined.

Predicting what will happen in 2012, therefore, is a shot in the dark: A year is virtually a lifetime in the digital era. And yet we can at least make a guess at what will happen in the early part of next year simply by looking at the trends that are shaping the latter half of this year.

1. Touch computing

New input methods will be the dominant trend of 2012. Tablet computers such as the iPad might seem like a nice alternative to desktop and laptop computers, but I believe they're more than that: They're replacements. Just as the command line (remember that?) gave way to graphical user interfaces, so the mouse will be superseded by touchscreens.

2. Social gestures

If you've seen apps such as Spotify or Social Reader in your Facebook news feed, you're already aware of these features.

The trend makes sense for social networks: With 800 million people already on Facebook, its growth is bound to slow. But if sharing becomes automatic, the volume of content on Facebook will grow at an accelerated pace. There's a big problem, however: Users may be "creeped out" by all this automated sharing of their Web activity and grow suspicious of the apps using it.

3. Voice control

Here's another trend that's got a moderate chance of taking off in 2012: Voice control.

Siri, the voice-control feature in the iPhone 4S, may spread to other devices.

The novelty of Siri on the iPhone 4S -- which allows you to send texts, create reminders, search the Web and much more using just your voice -- may be the start of a new trend in voice controlled devices.

Surely voice control has been around for years? Yes, but it wasn't very accurate.

Siri and its ilk define a new era in which we talk, and our devices understand -- often on the first attempt. Other device makers will likely follow suit. What's more, Apple may use voice control to replace the TV remote.

4. HTML5

Can I squeeze in one more trend? It's HTML5 -- the fifth iteration of the HTML standard -- and it lets developers create richer, more interactive applications than ever.

Why does this matter? As developers tire of building applications for every operating system out there -- from Android to iOS to Windows Phone and beyond -- HTML5 offers the opportunity to build an app once and have it work everywhere.

The rise of HTML5 is bound to be accelerated by a recent revelation: Adobe is killing off Flash for mobile devices, meaning one of the primary methods of serving videos and rich applications on mobile phones is about to disappear. HTML5 will fill that gap. For us as consumers, that means richer applications and experiences on all our devices.

In short, 2012 is all about new ways to interact with our devices through touch and voice control, new lightweight ways to share content, a revolution in mobile payments and a plethora of rich Web applications -- not to mention the hundreds of new innovations that we've yet to dream up. I can't wait.
