Bubble Hat, 2020.

“Bubble Hat” is a personalized health protection hat and wristband accessory to keep people safe in their environment. The hat is solar-powered and voice interactive. It circulates filtered air from the hat in a 2-foot radius to create a sanitary air bubble around users. The hat uses GPS and live environment health index data to determine its LED color. Green indicates safe direct contact conditions. Red indicates an unsafe environment for direct contact and encourages contactless interaction. A lidar sensor is used to detect motion between human interactions, prompting the hat to give feedback and voice guidance to the user. When touching things outside your bubble, the wristband accessory automatically sprays the refillable sanitizer, which dries instantly with bubble airflow. The hat also includes joint attach accessories including music, light, and personalized decorations. Additionally, the hat is customizable for weather, styles, and designs.
