NTT DoCoMo's Docotch 01 child-tracking watch has GPS, 3G and sensors for temperature and humidity as well as an accelerometer.

Japanese parents who want to keep close tabs on their kids will soon be able to wrap sensor-laden 3G watches on their wrists.

Mobile carrier NTT DoCoMo is moving into children's wearables with its Docotch 01, announced Tuesday in Tokyo.

The wristwatch has GPS for location tracking as well as sensors that can relay data on air temperature and humidity. An accelerometer can also show if children are running around or resting.

Knowing the temperature and humidity conditions around children could help prevent heatstroke on torrid summer days, a DoCoMo spokesperson said.

The watch has 3G so kids can message moms and dads. Meanwhile, parents can monitor their children remotely using a related app on smartphones, tablets or PCs.

When paired with a smartphone via Bluetooth, the watch will send an alert if a child wanders off at places like shopping malls or amusement parks.

Manufactured by Huawei Technologies, the waterproof, dust-proof, 50-gram Docotch 01 has a 1.3-inch display and lithium-ion batteries that can last about 72 hours.

It follows other monitoring bands for children such as LG's KizON wearable, but increases the amount of information available to parents.

There are no plans to release the watch overseas, but it could be an indication of how sophisticated kids' wearables will become.

DoCoMo plans to release the Docotch 01 in March. Though it could cost around ¥10,000 (US$91), the price has yet to be officially announced. The subscription service will cost ¥780 per month.

The telecom giant has released a number of cute, colorful mobile phones targeted at children. Its latest, the Kids Keitai HW-01G, has a panic alarm, GPS and a 2-inch QVGA display.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
