Body language, to be read on computers a new innovative solutions

Keyboard and mouse are no longer the only means of communication with computers. Modern consumer device responds to the touch of a finger and even the spoken word, but we can go further? Can a computer learn as we go and stand to understand our gestures and even our facial expressions to read a sense?

"The EU-funded MIAUCE project out to do just that."The motivation of the project is to people in the loop of the interaction between the computer and its surroundings ?, explains project coordinator Chaabane Djeraba, the CNRS in Lille.

"?We would like a form of ambient intelligence where computers are completely hidden ? to have, he says. ?This means a multimodal interface, so people with your environment interact. the computer sees your behavior and extracted then the information for the users useful."

It is difficult, imagine a world, where hidden computer try our needs to anticipate that the MIAUCE project has developed specific prototypes of the three types of applications.

Escalator accidents

The first is to monitor the security of the masses in crowded places such as airports and malls.Surveillance cameras used to detect situations such as accidents on escalators.

?The background technology this research is based on computer vision, ?, says Djeraba.?We extracting information from Videos.Dies is the basic technology and technical methods we use ?

It?s quite Herausforderung.zuerst must the video stream in real time to a hierarchy of three levels of functions to extract be analyzed the lowest level is a mathematical description of the shapes, this basic description of mass density is movements and fließt.Auf of the next level, speed and direction. The computer able to decide when the activity ?abnormal? perhaps because someone has fallen on an escalator and caused a pile-up, urgent intervention needed is is at the highest level.

It is at the second and the third ?semantic? level of interpreting MIAUCE was most vulnerable.

Is one of MIAUCE partners already working with a manufacturer of escalators to complement existing video monitoring systems at international airports, where hundreds of escalators grow.If a breakdown can automatically could be detected then the seconds in responding saved life and save.

But security is only one possible kind of application, where computer could read our body language.

Swap face

A second could ? Djeraba marketing specifically to monitor, analyze, like people walking in a shop as ?We like customers in shops behavior., says, ?and behavior of people in the shop where you for example ? look

The same partner is two products develop.Becoming a ?people Counter?, pedestrian flows in the Street outside one be to monitor shop.It is expected to gain wollen.Ein particularly attractive shops, passers-by another is a ?heat map Generator? movements of people within the store to see so that the Manager can see which parts of the displays to attract the most attention.

The third application that is resolved by MIAUCE choose interactive Web TV, a technology of growing interest in the Viewer, what you see is wollen.Als part of the project to see the Viewer?s webcam for monitoring your face which portion of the screen facing you used.

It could be used to feed the user more information based on the evidence of what you shown an interest haben.Projektpartner tilde, a software company in Latvia, this application is commercialization.

MIAUCE has developed a similar technology of ?face Swapping? where the Viewer?s problems.This could face that replace from a model to try hairstyles and clothes are used.

Ethics and anonymity

These are all ingenious applications but it is not ethical and legal behavior in this way to worry about reading People?s?

Djeraba recognizes that the project team took issues very seriously and several potential uses your technology were excluded for such reasons.

She worked to some basic rules such as cameras place on private premises and always with a warning label, but the basic principle was anonymity. ?We to anonymise people, ?, he says. ?What we do user behavior studied without any identification, this is a basic requirement for such systems. ?

She has also considered whether the applications for the society as a whole wäre.Niemand would acceptable reasonably object to monitor the escalators for B., if the goal was to improve the public Sicherheit.Aber technology must not identify individuals or even such features such as color of skin.

?Generally speak, anonymity is It?s OK critical Punkt.Wenn we anonymise if we anonymise Don?t It?s failed ? Djeraba says.
