Dog to human communication supported with technology

North Carolina State University researchers have developed a suite of technologies that can be used to enhance communication between dogs and humans, which has applications in everything from search and rescue to service dogs to training our pets.

“We’ve developed a platform for computer-mediated communication between humans and dogs that opens the door to new avenues for interpreting dogs’ behavioral signals and sending them clear and unambiguous cues in return,” says Dr. David Roberts, an assistant professor of computer science at NC State and co-lead author of a paper on the work. “We have a fully functional prototype, but we’ll be refining the design as we explore more and more applications for the platform.”

The platform itself is a harness that fits comfortably onto the dog, and which is equipped with a variety of technologies.

“There are two types of communication technologies,” says Dr. Alper Bozkurt, an assistant professor of electrical and computer engineering at NC State and co-lead author of a paper on the work. “One that allows us to communicate with the dogs, and one that allows them to communicate with us.”

“Dogs communicate primarily through body language, and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely,” Roberts says. “So we can determine when they’re sitting, standing, running, etc., even when they’re out of sight – a harness-mounted computer the size of a deck of cards transmits those data wirelessly.

“At the same time, we’ve incorporated speakers and vibrating motors, called haptics, into the harness, which enable us to communicate with the dogs,” Roberts adds.

“We developed software to collect, interpret and communicate those data, and to translate human requests into signals on the harness,” says Rita Brugarolas, an NC State Ph.D. student and co-author of the paper.

The technology also includes physiological sensors that monitor things like heart rate and body temperature. The sensors not only track a dog’s physical well-being, but can offer information on a dog’s emotional state, such as whether it is excited or stressed.

These technologies form the core of the technology platform which can be customized with additional devices for specific applications.

“For example, for search and rescue, we’ve added environmental sensors that can detect hazards such as gas leaks, as well as a camera and microphone for collecting additional information,” Bozkurt says.

Other applications include monitoring stress in working dogs, such as guide dogs and other service dogs.  Physiological and behavioral sensors will provide insight into a dog’s mental and emotional state.

“This platform is an amazing tool, and we’re excited about using it to improve the bond between dogs and their humans,” says Dr. Barbara Sherman, a clinical professor of animal behavior at the NC State College of Veterinary Medicine and co-author of the paper.

The research team has published their research in the paper entitled Towards Cyber-Enhanced Working Dogs for Search and Rescue
