The Catoptric Surface is an array of mirrors arranged on the interior of a large window which serves to manipulate the effects of natural lighting inside the room. The framework for moving the mirrors uses an interface which connects various Raspberry Pis and Arduino Unos to move stepper motors that connect to each mirror and move them as desired by the user. This kind of light manipulation allows the atmosphere of the room to be modified using natural lighting rather than artificial lighting and can be useful for varying the way people interact with a space. The intensity at which various configurations of the mirrors vary the lighting in the room becomes important for the user/controller of the Catoptric Surface to know in order to manipulate the mirrors in a fashion that will deliver the desired effect. Thus, in order to provide light concentration information to the user/controller, we have conducted a study in which we use a light sensor to gather the light concentration information (in lux) in the room with the mirrors in different configurations and discuss the implications of such measurements for future use of the Catoptric Surface.
