Researchers have created a system that could enable people with paralysis to control a wheelchair with eye movements alone. It requires a camera from a video games console, a modified pair of spectacles, and some clever code. The new eye-tracking system, from hardware that costs a few hundred dollars, rivals existing ones costing thousands of dollars. The system is good enough to control computer games but, say researchers, it could potentially even enable wheelchair control for people with disabilities. Aldo Faisal, one of the team behind the GT3D eye tracker joins Click to discuss the system.

German researchers have found a cheap way of gathering data on emigration in populations. In many countries gathering official statistics on migration is expensive and subsequently incomplete or out of date. But email accounts might change all that.

Have you ever imagined that a bridge sang to you as you walked over it? Well it might just be that you have been crossing the Millennium Foot Bridge in London.

The latest project, close to the iconic Tower Bridge, has been opened in time for the Olympic Games. Click talks with Martyn Ware and the poet Mario Petrucci about their collaboration on Tales from the Bridge.
