New system for monitoring health of guide dogs

The study, which was presented this week at the International Congress on Animal Computer Interaction, builds on previous work the team had done on measuring canine vital signs. With the addition of nonvisual feedback via the handle of the dog’s harness, the system can now relay that health information back to the handler in real-time.

Two vibrating motors are embedded in the harness handle. The first is by the handler’s thumb, and pulses in time with dog’s heart rate. The second, located by the fifth finger, vibrates in synch with the dog’s breathing, increasing in intensity as the respiration rate goes up.

“Our goal is to let guide dog handlers know when their dogs are stressed or anxious,” says Sean Mealin, a PhD student at NC State and lead author of the paper.

“This is important because it is widely believed that stress is a significant contributing factor to early retirement of guide dogs and other service animals. The technology may also be able to help handlers detect other health problems, such as symptoms of heat exhaustion.”
