In the air, in your car, on your back -- new technology at the upcoming Consumer Electronics Show is showcasing the growing number of ways to live the "connected life." The  "Internet of Things" is leading to a wider range of wearable tech, from sports shirts to smart watches to sleep monitors to connected refrigerators.

The vast 2015 International CES, one of the world's biggest electronics fairs to be held in Las Vegas January 6-9, shows how technology is permeating virtually all sectors of life -- from entertainment to automobiles to kitchen appliances, in sectors including health, fashion and sports.

"The 'Internet of Things' is the hottest topic in tech right now," said Karen Chupka of the Consumer Electronics Association, which organizes the annual event. "It's all about the opportunity to connect everyday items like cars, home security systems and kitchen appliances to networked devices like PCs and smartphones for greater control and management of our everyday lives."

Also on view will be the newest and biggest television displays featuring "ultra high definition" that is catching on with consumers.So-called 4K television sets are coming down in price and becoming mainstream, and some reports suggest the show may feature newer, even more realistic "8K" displays.

Roger Kay, analyst at Endpoint Technologies Associates, said that 4K "is a really obvious play for the industry and consumers" because it can mean big-ticket purchases, and deliver a better image. While 4K television has been around a few years, the market may be ready now, says Bob O'Donnell at the research firm Technalysis, with prices for TV sets falling below $1,000.

The 4K format "is more 3D-like than 3D," O'Donnell said. "The quality is so high it makes you feel like you're there." Curved and bendable screens should be on display, and perhaps some folding ones as well.

In the air, CES will for the first time have a dedicated space for drones to accommodate the growing interest in unmanned flying devices. This comes with interest in drones for everything from law enforcement to crop management to search-and-rescue missions.

A separate robotics zone will be 25% bigger than last year, with at least 18 exhibitors. Some robots are connected to the Internet cloud, or controllable by mobile device and capable of seeing, hearing, feeling and reacting to the environment.
