Smartwear revolution promises healthier lives

A new generation of wearable technology is promising not only to log data about users' health but to predict and avert crises -- from drivers falling asleep at the wheel to runners wearing themselves out in a marathon.
But there are concerns over the accuracy of the personal information collected by the burgeoning range of smart wristbands, watches and clothing -- and how companies might use that data.
Wearable technology is the fastest growing category at this year's Computex, Asia's largest tech trade show which kicked off in Taiwan on Tuesday, with health-tracking a dominant theme.
"Health and fitness sensors and data are fundamental for wearables and largely define the category," said Daniel Matte of market research firm Canalys.
Market tracker IDC predicted in April that sales of wearable tech items would triple this year to 19 million units worldwide, growing to 111.9 million by 2018, according to AFP.
