A method for a hand-held device comprising illuminating, with a first UV LED associated with the hand-held device, a surface of an object with UV light, acquiring with a visible-light image sensor on the hand-held device, a first image of the surface of the object while the surface of the object is illuminated by the first UV LED, performing with the processor in the hand-held device, a function upon the first image to determine a type of contaminant disposed upon the surface of the object, determining with the processor in the hand-held device, sanitation techniques to perform in response to the type of contaminant that is determined, and displaying with a touch-screen display on the hand-held device, the sanitation techniques to the user.

Ultraviolet light source and methods

A UV illumination method includes moving a UV peripheral separate from a smart device to location associated with a plurality of target surfaces, selecting a UV illumination application executing upon the smart device, selecting an icon from within the UV illumination application, sending via a wireless communication mechanism of the smart device to the UV peripheral, instructions to turn on a UV light disposed in the UV peripheral in response to the selection of the icon, receiving via a wireless communication mechanism disposed in the UV peripheral, the instructions to turn on the UV light, illuminating, with the UV light within the UV peripheral, sanitizing UV light to the plurality of target surfaces other than surfaces of the smart device in response to the instructions, and thereafter terminating illuminating, with the UV light within the UV peripheral, the sanitizing UV light from the plurality of target surfaces.
