Outcry in China over hit-and-run toddler left in street

The incident was captured on surveillance cameras
Chinese media and internet users have voiced shock at a hit-and-run incident involving a two-year-old child left injured in the road as passers-by ignored her.

The toddler was hit by a van on Thursday in the city of Foshan.

After the van sped off, several pedestrians and vehicles passed the girl without stopping. Several minutes later she was hit by another vehicle.

A rubbish collector finally helped her, but she is said to be seriously hurt.

The incident was captured on surveillance cameras and aired on local media.

'Lacking conscience'
The footage showed the van hitting the little girl, pausing briefly while she was under the vehicle and then driving off, running over her legs.

It then showed about a dozen passers-by, including cyclists, a motorcyclist and a woman and child, noticing the little girl lying injured in the street but walking on.

New emotion detector can see when we're lying
By Hamish Pritchard
Science Reporter, Bradford
A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say.
The computerised system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms.
Researchers say the system could be a powerful aid to security services.
It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University.
The system, developed by a team from the universities of Bradford and Aberystwyth in conjunction with the UK Border Agency, was unveiled today at the British Science Festival in Bradford.
This new approach builds on years of research into how we all unconsciously, involuntarily reveal our emotions in subtle changes of expression and the flow of blood to our skin.
We give our emotions away in our eye movements, dilated pupils, biting or pressing together our lips, wrinkling our noses, breathing heavily, swallowing, blinking and facial asymmetry. And these are just the visible signs seen by the camera.
Even swelling blood vessels around our eyes betray us, and the thermal sensor spots them too.
Real-world test
Traditional lie detection depends on the venerable polygraph, first developed in 1921, a much more invasive apparatus with a set of wires attached to the skin. This new device promises non-invasive, even covert truth tests in real time.
"We bring together all this well-established work on expressions, these recent developments in thermal imaging, techniques for image tracking of subjects and our new algorithms into one operational system," said Professor Ugail.
So far, the team has only tested its lie detector on willing volunteers rather than in a real-life, high stakes situation. Later this year, though, they plan to deploy it in a UK airport, probably running alongside experienced immigration officers as they conduct security interviews. The algorithms can then be tested against the verdicts of these officers.
"In a real, high-stress situation, we might get an even higher success rate," noted Professor Ugail, who believes he'll eventually be able to detect around 90% of those who are lying, which is similar to the performance of the polygraph.
The researchers acknowledge, though, that these tests can never be 100% accurate.
What they detect are emotions, such as distress, fear or distrust, and not the act of lying itself. Fear can sometimes be the fear of not being believed rather than the fear of being caught.
