Abstract: A method for detecting an orientation of a screen of a device includes having a two-dimensional (2D) detector array affixed to the device in a fixed orientation relative to the screen, where the 2D detector array includes a sensing area with a plurality of pixels; imaging a scene including a user in a foreground and a background onto the 2D detector array; extracting an information of the scene for each of the plurality of pixels of the sensing area, the information being extracted from the 2D detector array by an image sensor; identifying an asymmetry in a pixelated image of the scene that includes the information of the scene for each of the plurality of pixels of the sensing area; and based on the asymmetry in the image of the scene, determining the orientation of the screen relative to the user.
