It's easy to imagine using Google Glass for hands-free directions, phone calls, video recording and more, but JetBlue took it one step further in a Google+ post this week.

The airline piggybacked the #ifihadglass social media campaign to remind its fans that it's the coolest airline around, publishing several pictures of imaginative ways to use Google Glass in and around an airport.

The #ifihadglass hashtag was spawned by Google to encourage, and Google Glass hopefuls used the hashtag to enter for a chance to win the opportunity to do Google's marketing for it.

If that sounds a little twisted to you, JetBlue's hypothetical Google Glass uses might just make you feel better.

And that's why we want Google Glass

Hypothetically speaking, of course.

JetBlue posted on Google+, "#ifihadglass we would continue to help the world view air travel through a whole new lens," and included several mock-ups of Google Glass being used around an airport.

First, Google Glass could display in real-time how much space is left in a parking structure when you're driving up.

It could display your flight status without you having to search frantically for a TV screen in the airport, then point out available power outlets while you're waiting to board.

After the flight, Google Glass could tell you where your baggage will be and when it will arrive.

Finally, JetBlue contends that Google Glass could estimate your cab fare outside the airport.

We have a winner

JetBlue stands a respectable chance of taking the crown in the #ifihadglass campaign with these ideas, though no doubt if it really wanted a prototype Google would probably supply it one regardless - especially with applications like these in mind.

In related news, the airline posted a comment response to a request that it adds these features to smartphone apps before looking to future tech like Google Glass.

"We're always looking at features to add to our Android and iOS apps," JetBlue wrote, "and love the idea of streamlining the experience, not just from gate to gate, but from door to door."

It added that mobile boarding passes for Android are "nearly here."

Sony Electronics president and COO Phil Molyneux recently shed some more light on the notion that the PlayStation 4 will be able to support 4K ultra-high definition content. The executive said we will not be disappointed when asked if Sony’s upcoming 4K movie download service would be coming to the PS4 during a recent interview with The Verge in New York.

Here’s what we know at this point. Late last year Sony’s Ray Hartjen revealed the fact that the XBR-84X900 Ultra HDTV set will include the world’s first 4K Ultra HD delivery solution. That service was showcased during CES where we were told it will be launching in the US sometime this summer.

Fast-forward to the PS4 unveiling just last month where, in the days following the reveal, we learned that the console will support media output resolution at 4K for photos and videos but not games.

Talking specifically about the 4K video service, Molyneux said the size of a typical movie download could be 100GB or more. Another key factor that comes into play is the speed of your broadband connection which is described as one of the challenges they have to work though. He noted that they had some really good ideas that will make for a comfortable consumer experience and looking to the future, the industry as a whole needs to look into developing new compression ratios and technologies.

Molyneux said he wasn’t discounting the idea of physical 4K distribution but he believes consumers are moving more towards downloads and streaming since they are already used to it.
