CRI听力:State-of-art Products at Mobile World Congress in Spain

Augmented reality games maker Chromville is demonstrating its latest educational app allowing children to turn their drawings into smart, interactive learning tools.

Children download and print pages which feature designs they can then colour in however they wish.

Then, they hold a tablet over the coloured page and - via the Chromville app - up pops a fun and interactive augmented reality image.

Children can then interact with the image to study and learn basic science.

Hector Paz is the CEO of Chromville.

"Our real aim with this application is to figure out the real passion of the kids, we are creating several apps and the idea is to know their real passion."

Elsewhere, Food tech maker Natural Machines is demonstrating its Foodini 3D food printer at 4 Years From Now.

The company claims the fast-printing device lets chefs create complex dishes using natural ingredients, rather than buying foodstuffs with added preservatives.

Layer by layer, Foodini can print a growing list of tasty treats, including ravioli, crackers, mashed potatoes, cereal, and even hamburgers.

Lynette Kucsma, the co-founder and CMO of Natural Machines.

"We think in the next ten to fifteen years, you're going to see it in all kitchens, both professional and home kitchen users. So the initial market for 3D food printing is really more targeted towards the professional market - Michelin-starred chefs, restaurants, hotels, any type of professional kitchen. The idea is that if you're going to get used to eating 3D printed food outside of your house, it's not such a big jump to get it down the road in your house."

Japanese smartphone vendor Kyocera is showing its latest range of smartphones at Mobile Focus Global on the eve of the Mobile World Congress.

The phones are scratch proof, waterproof, dust proof and shockproof. They can be dropped, submerged in water, hit or stepped on.

John Chier with Kyocera said the real main market for a device is going to be businesses and people who work in rough environments.

"Whether it's wet, dirty, whether you just, the phones have almost become disposable. When you need a phone that's really going to stand up and last, and take a beating in a job, that's going to be the primary market. And a secondary market is for people who really like to be outdoors, extreme sports, snow skiing, surfing, hiking, where you're going to get wet, dusty, dirty."

The annual Mobile World Congress is the world's largest gathering for the mobile industry. This year the four-day exhibitions attracted 2,100 companies and 95,000 visitors.
