10 years in the making, the Dogosophy Button was codesigned by dogs and humans. For decades, people with disabilities have relied on service dogs to help them perform daily tasks like opening doors, turning on lights, or alerting caregivers to emergencies. By some estimates, there are 500,000 service dogs in the U.S., but little attention has been paid to the fact that these dogs have been trained to interact with interfaces that are made for humans. A team of researchers from the United Kingdom wants to change that by designing accessible products for, and with dogs.
