Smartwatches, intelligent homes shine at Berlin mega gadget show

Smartwatches, intelligent homes and drones that follow users wherever they go are on show at Berlin's mega consumer electronics fair, which opened its doors to the public on Friday.

Here are some of this year's eye-catching trends and innovations at the six-day showcase:

Smartwatches go round

Samsung, Huawei and Motorola pick spherical faces for their latest smartwatch offers, giving them a distinctly different look to arch-rival Apple Watch, which has a rectangular face.

Keeping track of emails, water versus caffeine intake or how many steps taken in a day, are among the myriad functions offered by the intelligent wristwatches.

The Android smartwatch makers are hoping that their models will claw back some market share from Apple, which shipped about four million smartwatches globally in the second quarter, market researcher Strategy Analytics estimated in July.

Samsung had shipped just 400,000 units in the same period.
