KTF Launches Service Interpreting Dog's Bark
"South Korean wireless carrier KTF launched a new service that enables dog owners to know whether their pets are feeling happy or sad. Users must first connect to the Internet with their wireless phones, then register information regarding the dogs breed and age. The service will then record the dog's bark. The owner will receive text messages telling them how the dog feels, such as "I am happy" or "I am frustrated". (Source: Associated Press)"
I really don't think there's much more I can add to this.
I think one thing that it does show – it's very hard to predict what will be a successful wireless data service. It also gives weight to the side of the argument for carriers to open up their networks – let the consumers decide what applications and content they want.
