Lumos utilizes pulse monitors found in most hospitals, and creates a calming pulsing light pattern shown to help regulate heart rate and breathing patterns, and aid in the reduction of anxiety. Lumos could also be integrated with other biosensors or utilize computer vision to recognize facial expressions and generate responses. When a child is first admitted to the hospital, the child has the option to choose her/his favorite color from a selection of calming colors, adding a personalized touch to the room.
