1. A system comprising:
a lighting array including a plurality of antimicrobial lighting segments, each of the antimicrobial lighting segments including one or more light source elements configured to emit antimicrobial light within one or more antimicrobial wavelength ranges; and
a lighting controller comprising one or more processors configured to:
receive object type information associated with a touch object, wherein the object type information specifies at least one of a type of the touch object or a material of the touch object;
determine, based on the object type information, a dosage to be applied by the lighting array to inactivate one or more microorganisms on one or more touch surfaces on the touch object, wherein the one or more processors are configured to, as part of determining the dosage, determine antimicrobial wavelengths for an antimicrobial light treatment, the determined antimicrobial wavelengths being within the one or more antimicrobial wavelength ranges; and
activate selected antimicrobial lighting segments of the plurality of antimicrobial lighting segments such that the lighting array applies the determined dosage to the touch surfaces on the touch object.
