Haptic feedback harnesses for seeing-eye dogs have jumped off the ol’ drawing board. A blind dog owner himself, Sean Marlin, lead author of the research paper on the experimental harness, tested the leash system, which contains an electrocardiogram and plethysmograph.

The dog’s heart rate and respiration are monitored, and the output is processed by an aptly named Beaglebone Black microcomputer at the harnesses’ base. Blind dog owners can now rely on their guide dogs’ cues with vibratory monitors at both sides of the leash handle.

You can also select the audio option via a Bluetooth headset too. This feature is being tested to remotely monitor the well-being of search and rescue dogs in dangerous situations.
