The rim area (3) may comprise a sensor (31-50) for detecting the second information that may comprise light originating from the display area (2). The rim area (3) may further comprise a lens (51-70) for focusing the light on the sensor (31-50). The lens (51-70) maybe a lenticular and/or cylindrical and/or convex lens. The object (20) comprises a reflector (21) for reflecting the second information from the display area (2) to the rim area (3). A device (100) comprises an interactive display (1) and a controller (101) for controlling the interactive display (1) for defining a part of the display area (2) from which part the second information originates and/or for defining a frequency and/or time-dependency and/or intensity of the second information.
