Struggling computer maker Dell is considering a move into the “wearable computing” space, as it grapples with the effects of a shrinking PC market. Sam Burd, Dell’s global vice-president of personal computing, told the Guardian that “we’re exploring ideas in that space”. The idea of computers that can be worn on the body has become one of the hottest spaces in the technology business. Google has thousands of people testing its head-mounted Glass system, while the Californian company Pebble has sold more than 85,000 of its Bluetooth-connected “smart watches”. Persistent rumours suggest that Apple will introduce an “iWatch”, while companies including Samsung, iPhone maker Foxconn, Sony, LG and Philips have announced – but in only a few cases unveiled – wearable devices.
