Watching the World Understanding Dog Language? A Japanese toy maker has developed a device purported to translate dog woofs into human words, reports Japan Information Network. The gadget is made up of a wireless microphone that attaches to a dog’s collar and transmits sounds to a small receiver. The receiver supposedly analyzes the dog’s sounds and classifies them into six emotional states: frustration, anger, happiness, sadness, desire, and assertion. The results are shown on the receiver’s liquid crystal display, and they include such phrases as “I’m feeling great! ” “ It’s so annoying! ” and “Come on, play with me! ” The manufacturer said that it sold 300,000 of the $100 devices in Japan and hopes to reach one million units when it is introduced in South Korea and the United States.
