Done in collaboration with Samantha Freedman and Lucy Mou, Key is a playful proposal for how parents can grant children access to unmanned, autonomous vehicles. Instead of relying on cell phone verification or biometric data to grant car access, the child can wear a bracelet that acts as a key to the car. The parent and child have a shared gesture and when the child traces the gesture onto the bracelet they are granted access to the vehicle. The parent could also use the app to control designated routes, modify the gesture, control access times, and keep track of their child while their in the car. We did not want to focus on the key as a safety tool but also as something that could actually help the child bond with their parents.
