Wearable Tech for Dogs
FIDO
“The mission of the FIDO project is to develop wearable technology that will improve communication between working or assistance dogs and their handlers. The project aims to allow bomb sniffing dogs, rescue dogs, or guide dogs for people with disabilities to communicate information to their handlers or owners by biting or tugging at sensors fitted on their collars or vests or gesturing with their noses. The sensors would activate either audio commands that handlers would hear on their earpiece or visual commands that would appear on a head-mounted display.”
