This invention describes an input device, like a keyboard or touchscreen, that can disinfect itself using ultraviolet (UV) light. It works by having a UV light source inside the device that shines through a special transparent outer layer, killing germs on the surface you touch. The system can also collect data on usage and disinfection effectiveness, potentially using this information to adjust the UV treatment and provide feedback.
Why it matters: The sophisticated data collection and dynamic control described, particularly for behavior modification, is more achievable with today's advanced AI/ML and sensor integration, which have matured significantly since 2021.
