1. An apparatus comprising:
one or more dimming films;
a power source device connected to the one or more dimming films;
a sensing module configured to generate sense data, wherein the sensing module includes:
a light sensor configured to sense an illumination intensity of light from a light source on a first side of the one or more dimming films in real-time, and
a beam analyzer configured to sense an illumination angle of the light from the light source on the one or more dimming films in real-time;
a recognition module configured to generate recognition data, wherein the recognition module includes a facial recognition device configured to track locations of eyes of a user on a second side of the one or more dimming films in real-time, the second side being opposite to the first side; and
a control module coupled to the power source device, the sensing module, and the recognition module, wherein the control module is configured to:
receive the sense data from the sensing module, wherein the sense data indicates the illumination intensity of the light from the light source on the first side of the one or more dimming films and the illumination angle of the light from the light source on the one or more dimming films,
receive the recognition data from the facial recognition device, wherein the recognition data indicates the locations of the eyes of the user on the second side of the one or more dimming films,
determine a target adjustment area on the one or more dimming films based on one or a combination of the illumination intensity of the light from the light source, the illumination angle of the light from the light source on the one or more dimming films, and the locations of the eyes of the user on the second side of the one or more dimming films,
determine a target transmittance percentage for the target adjustment area based on one or a combination of the illumination intensity of the light from the light source on the first side of the one or more dimming films, the illumination angle of the light from the light source on the one or more dimming films, and the locations of the eyes of the user on the second side of the one or more dimming films, and
determine an adjustment signal for the target adjustment area for adjusting a transmittance value of the target adjustment area on the one or more dimming films to the target transmittance percentage.
