An exhibition in Tokyo is putting the spotlight on cutting-edge wearable devices, including shirts with sensors that might help prevent heatstroke.
More than 160 companies are showcasing their technologies and products at the 4th Wearable Expo.
One set of goggles features augmented-reality technology. They project digital images over real-life scenes.
The developers believe the eyewear can be adopted on factory floors. Workers could view instruction manual in the goggles. That would leave their hands free, so they can carry on working.
A textile maker is displaying shirts with sensors to gauge the wearer’s heart-rate and other biometrics. The data can be sent to smartphones or tablets.
The company says the devices are being tested out on construction workers to see if the technology can prevent heatstroke in the summer.
