(CNN)For years, travelers have been promised a Jetsons-like future, one complete with driverless vehicles, robotic personal assistants and streamlined service fueled by artificial intelligence.

Sometimes, that vision can feel frustratingly remote (particularly when one's squashed in an economy class seat).
However, some of the innovations unveiled this month at CES 2016, a mammoth technology trade show in Las Vegas, really could revolutionize how we travel.
Here's what's in store for the next five years.
Both virtual reality and eye-tracking technology were major themes at this year's show. In addition to the extraordinary implications for gamers, these advances could also, potentially, be used to improve the flying experience.
"One thing we've seen in constant development is how the travel providers plan to use (this technology) to manage passengers and property," notes David Low, a developer advocate at travel booking site Skyscanner.
He paints a picture whereby airline staff, perhaps donning the next iteration of Google Glass, will be able to determine passengers' needs simply by looking at the cabin.
"An airline might get an advanced view of passenger needs, and staff could look at a cabin and see who needs attention, and when, say, someone in business class has the wrong seat," he adds.
While 2014 was a seminal year for virtual reality (Google Cardboard was released and Facebook acquired Oculus Rift), in 2016 the technology will truly go mainstream.
Google is only just starting to develop apps for Google Cardboard and this year will likely introduce some that really open up the product's capabilities.
"Facebook put their weight behind Oculus Rift a couple of years ago, and the technology is starting to catch up," notes Low.
Currently, travelers sample a destination before they go (this is made possible with the Google Cardboard and Streetview apps). Soon, they'll be able to customize the world they want to experience.
"Hotels are starting to use these things so that you can pick out a room, and have it laid out the way you want before you go. It's not hugely different from 360-degree panoramas, just deeper," he says.
Electronic personal assistants are going to get smarter, notes Low, and, for the same reason, search engines -- particularly for travel -- are going to get more sophisticated.
Low is currently working on Skyscanner's conversational search technology, which will integrate with Amazon's Echo system.
"If you want to find a flight, you normally start at Skyscanner and filter down. With a conversational search, you can tell it, 'find me a BA flight on Monday,' and it filters to give you what you want quicker.
"We can also use personalized info to refine more as you go along," he notes.
Samsung made headlines at this year's CES with its new Family Hub refrigerator.
Connected to the Internet and kitted out with a 21.5-inch HD touchscreen and speakers, the Family Hub allows users to see what's in their fridge without opening the door. It's also capable of communicating with all your other appliances.
In the future, you might not even have to turn on a computer, or even a phone, to book a ticket.
Nothing in the fridge but you fancy dinner in Paris? Simply shout your demands to the nearest appliance.
Yes, we're all waiting with baited breath for driverless cars, but how about driverless helicopters?
Chinese company Ehang unveiled the world's first passenger-carrying drone at CES this year.
The drone can seat one passenger -- but no pilots. Rather, you key in where you want to go and get whisked there in the air.
What if there's an emergency, you ask?
Just hit a button and the drone will hover in the air, presumably waiting for backup (the equipment is supported by a real-time command center).
