Contact lens to get built-in graphics

A contact lens that harvests radio waves to power an LED is paving the way for a new kind of display. The lens is a prototype of a device that could display information beamed from a mobile device. Realising that display size is increasingly a constraint in mobile devices, Babak Parviz at the University of Washington, in Seattle, hit on the idea of projecting images into the eye from a contact lens. One of the limitations of current head-up displays is their limited field of […]



To protect your privacy, hand over your data

Verifying your identity generally comes down to entering one “key” that only you can provide – be it a password, credit card number or RFID tag. That’s not good enough, according to a new proposal, which suggests that our digital identities will be more secure if they rest on reams of data on our everyday life culled from cellphones, online transactions and the like. The idea comes from Alex Pentland at the Massachusetts Institute of Technology’s Human Dynamics Laboratory. The lab is a pioneer of […]



Live Video makes Google Earth Cities Bustle

Live Video makes Google Earth Cities Bustle

Virtual globes such as Google Earth or Microsoft Visual Earth provide great bird’s-eye views of urban landscapes. But those streets are empty, transforming the world’s cities into ghost towns. Now a system that can draw on real-time video from traffic and surveillance cameras, or weather sensors, is set to change that. It populates virtual towns with cars, people and realistic skies. The video above shows how computer scientists at Georgia Institute of Technology in Atlanta put the idea into practice using video feeds from cameras […]
