In our world where communication is essential we will provide technology in the future with information about how we feel by facial expressions and gestures. In human language this is a normal way to communicate but in the interaction between man and machine this is new. Because of humans natural way of interacting by gestures or facial expressions some people are develloping technologies which allow us to interact with technology by using our body and face. Some researchers at Stanford University have already come up with a system that can read such signs to tell whether a person is interested, happy, or annoyed. And they can even map those responses onto the face of an avatar in a virtual world.

1. Toyota and Nissan sponsor research at Stanford investigating the expressions drivers typically have before they fall asleep. By detecting their facial expressions with simple cameras installed in a steering wheel or dashboard they can give an alarm before a driver falls asleep.
2. The company Mova can make avatars very realistic. With their technology the make the virtual world as realistic as the physical world. The internet loses her cartoon image and becomes as real as real life.
3. Game devellopers use our gestures more and more in the devellopment of games. New York Mets star David Wright was filmed by a game develloper to add his movements in a new baseball game.
4. Adidas had an interactive wall in a subway station in New York which showed, when people walked by, shoes started falling down in the section of the wall where they are gesturing. The more they waved, the larger the shower of shoes.
5. Stanford University Medical Media and Information Technologies Lab, in Palo Alto, has made it possible to practice cutting, cauterizing virtual organs. Force feedback technology is built into the surgical tools so that a virtual heart feels different then a lung. Doctors apart from each other can work together on the same virtual organs. Very interesting in this is the website of Virtual Human Interaction LabStanford.
6. Siemens develloped a camera which uses infrared signals to detect the awareness of a drives. When the get sleepy the camera gives a warning signal.

Al these developments show how we will provide technology with information just by passing by or looking at them. This information is used by the same technology to interact better with us.
