Scientists from Auburn University have built what they're calling "a system for autonomous canine guidance," a.k.a. a dog remote. The system is made up of a microprocessor, a GPS receiver, a wireless radio and an attitude and heading reference system. It replaces spoken commands with vibrations or tones. The system works pretty well. In preliminary tests, dogs responded correctly to cues 98 percent of the time.

With a GPS chip you can keep track of where the dog is and send commands wirelessly to the device. It would also enable guide dogs to follow directions from place to place. So, no more talking to your dog now? What do you think? [Science Daily]
