Expressing feelings is
something not even all humans are entirely capable of.
And now a humanoid robot named Kansei is able to frown or smile
according to a flow of artificial consciousness.
Kansei's ability to communicate feelings makes it one step closer to
recognizing when humans are happy or sad, an important
characteristic for machines expected to one day help care for the
elderly, clean house, or greet people at a reception desk.
Kansei, which stands for "sensibility" and "emotion" in Japanese,
also contains speech recognition software, a speaker to vocalize,
and motors that contort artificial skin on its face into
expressions. The robot could even one day learn to distinguish and
articulate whether foods taste good or bad.
Takeno and his team built a software program that extracts word
associations from a database of 430,000 words, in order to give
Kansei an artificial consciousness. The word database was built from
sentences gleaned from the Internet, which is a type of large-scale,
convenient and constantly updated database in itself.
The software program then assigns values to the world associations,
calculates the values, and then prompts the robot to express whether
something is pleasant or unpleasant based on the value.
Its program will produce both negative and positive values. But
after everything is calculated, if the negative values are greater
than the positive, Kansei will frown. If the positive values are
greater, Kansei will smile.
"Kansei is a comprehensive concept useful for the design of human
interface. It includes sensibility, sensitivity, feeling and
emotion," said Shigeki Sugano, professor of mechanical engineering
at Waseda University in Tokyo and an expert in humanoid robots.
Well, I guess that kind of brings Data this side of the screen, so
Star Trek is more science and less fiction these days...
