Thousands of people were in the American state of Nevada earlier this month for the Consumer Electronics Show.

The CES is the world's biggest show for electronic devices. It is held every January in the city of Las Vegas. The CES is said to be a guide to the path technology companies will follow in the coming year. The show offers visitors a chance to see high-tech products that may change our lives -- or may never be seen again.

Some of the products are fun, while others are useful. From high-tech cameras to instruments for measuring physical fitness, these new gadgets and services are meant to make our day-to-day activities easier.

These products are either being sold now or should be available later this year.

1. Polar Balance Smart Scale

Polar Balance Smart Scale

Activity trackers can help you keep records of your activity levels and physical exercise. But how many trackers will connect with a scale to measure your weight? The Polar Balance Smart Scale connects to an activity tracker and a software program to show whether the exercise affects your weight. The software application can be downloaded on your phone.

Set a weight goal using the Flow app. Then get weighed on the Smart Scale. The Flow app also connects to a calorie counting app if you want to follow what you eat.

Polar Coach, a free service, uses information from the Smart Scale, activity tracker and the Flow app to help you reach your goals.
