CES 2015 is, similar to last year, bigger than its predecessor. More people, more eyes on gadgets that are arranged abundantly on the exhibit floor. The theme which will strike CES 2015 guests and which has made considerable progression over the past few years is Automation, according to Tech Crunch.

While robots are nothing uncommon for CES, CES 2015 is reportedly a turning point for introducing automation to a wider range of device categories and providing 'robots' a wider array of platforms in verticals.

Among gadgets featured during CES 2015 were automated ones for maintaining plant health, drones able to fly in flocks and offer up comprehensive imaging for agricultural use, sensors that allow for tying into more simplistic smart gadgets for advanced smart home design and lots more.

Showing mostly realistic robotic hostess in CES 2015 is Toshiba. Intel and iRobot also teamed up to show off autonomous telepresence bots, while talking long-term plans for a robotic butler.

For Tech Crunch, most impressive during CES 2015 were the advances in car automation. Virtually every auto maker at the show reportedly offered a glimpse into some kind of intelligent, driver-free technology, ranging from parking to advanced object recognition.

An example of one of the huge changes that took place over the past four years of CES was the Audi exhibit showing four generations of driver-assist automated car tech.

For CES 2015, Audi brought four cars to the show, from model year from 2009 to 2014. Each year, there's a different kind of advance in technical advancement.

Also in CES 2015 were the likes of Ford, GM, BMW and Hyundai. There was also a new prototype launch and the first ever glimpse of the new Chevy Volt.

Meanwhile, the tech company truly driving the trend at CES 2015 is QNX with its QNX Car platform, which has proven to be most disruptive, reports engadget.com.

While there was countless innovation featured at CES 2015, it reportedly felt like there was no big launches of gadgets defining a new category this year, with the show appearing less focused, reports the BBC.

There was a good reason for the lack of wow factor from the biggest consumer electronics firms, said Stuart Miles, founder of gadget news site Pocket-lint, and who has attended CES for the last 15 years.

"They don't like being told when to launch," he said.

The debut of a consumer gadget these days is, Miles said, not trivial and fewer firms seem keen to do for a show which falls after one the busiest buying seasons, such as CES 2015.

Those big electronics firms instead prefer to do the launches at their own event and do the launches as the beginning of their long marketing campaign for any type of gadget.

He added that CES is just an event which any firm, no matter the size, would find hard to make its gadget stand out. With a sheer size of 160,000 attendees, 52,000 exhibitors and 20,000 product announcements, some big firms truly scaled back their presence since it was so hard to make the event work for them.

Big players running their own launch events at other times doesn't mean an "existential crisis" which leaves CES 2015 losing relevance either, said Martin Garner, another veteran CES goer from analyst house CCS Insight.

"The people who worry most about the lack of focus are those who try to digest it all, the analysts and journalists," he said. "Most people attending are within an industry and focus mostly on that industry while at CES. The show is about their category and nothing but that category."

CES 2015 had been a blast, to say the least, and CES 2016 is now expected to become a bigger deal, for sure. CES, it seems, has a found a new direction. While it's still too early to tell for certain, it appears automotive is the new path for CES.
