Want to be original next Valentines day? Here's your ticket, it's called a KOTOHANA. In a nutshell it's a mood sensing terminal in the shape of a flower. Each flower contains a microphone that captures voice data for emotional processing, the results of which are sent via wireless LAN to the counterpoint flower. Then, the embedded LEDs in the KOTOHANAs change color -- yellow for happy, blue for sad, and so on -- depending on what the person who's hanging on to the other one is feeling.
They're able to figure out moods with an "emotion recognition engine" called Sensibility Technology (ST), developed by SGI Japan with the cooperation of AGI, which detects joy, sorrow, calmness and excitement in speech patterns. As emotions change, the changes show via color gradations and variations in brightness.
The KOTOHANA isn't in production yet, but it'll be shown at CeBit in Hannover, Germany, which starts on March 9.
