Abstract
A passenger interface device (20) includes at least one input member (22, 24, 26) having a contact surface (28) that is adapted to be touched by an individual. A disinfectant (30) is on the contact surface (28). The disinfectant (30) comprises a radiation-activated material. A source of radiation (32) irradiates the disinfectant (30) to disinfect the contact surface of the passenger interface device. In one example, titanium dioxide is used as a photocatalyst that disinfects the contact surface responsive to ultraviolet light radiation.
