Yes NITRC Fiber Optic Button Response System The Fiber Optic Button Response System accurately gathers participant responses and verifies signals. The Celeritas Series response units are assembled using high-impact, chemical resistant, medical grade plastic. The response units include a tactile indicator to ensure correct finger placement during experiments and comfortably attach to the participant’s wrists. The units communicate button presses through fiber optic cabling which connects to a Fiber Optic Interface Console located in the control room through an available wave guide. The interface console provides real-time feedback of participant responses via LED indicators and includes a set of switches which can be used to make responses for the participant as needed.
