Internet of Things Devices Will Dwarf Number of PCs, Tablets, and Smartphones

ZDNet (12/13/13) Colin Barker 

The Internet of Things (IoT) will grow into a $300-billion industry by 2020, with increasing numbers of devices containing embedded technology to sense internal states or external environments, according to Gartner. From today's 0.9 billion units, the IoT is expected to rise to 26 billion units by 2020, marking nearly a 30-fold increase. Gartner says this trend will drive $1.9 trillion in global value from sales into an increasingly diverse market. Devices with computing capabilities, such as sensors that monitor traffic, have experienced strong growth in recent years, and Gartner predicts that smart devices are poised to overtake PC and phone growth. Advanced medical devices, factory automation sensors, industrial robotics applications, and sensor motes for greater agricultural yield are among the areas expected to undergo rapid growth in coming years. Component costs by 2020 will drop sufficiently to make connectivity a standard feature, even for processors that cost less than $1, enabling nearly any device to be connected, says Gartner's Peter Middleton. "As product designers dream up ways to exploit the inherent connectivity that will be offered in intelligent products, we expect the variety of devices offered to explode," Middleton says.

Google Glass's Word on the Street Now Easier to Read

New Scientist (04/19/13) Paul Marks

Wearable displays such as Google Glass and the Epson Moverio will enable users to read what is written on them as they walk down the street.  However, the text will need to stand out from the constantly changing background, considering that the user could be in a dimly lit room one minute and under a bright blue sky the next.  Jason Orlovsky and colleagues at Osaka University have developed a text display algorithm that places the current message on the darkest region in view at any given moment and in a readable color.  The handset's camera will plot a constantly changing heat map of viable on-screen reading locations.  The algorithm also can split up a message into two small dark regions on either side of the user's field of view.  "Twitter feeds or text messages could be placed throughout the environment in a logical manner, much like signs are placed on either side of a street," the developers say.
