Abstract:
1. A monitor device comprising: a projection screen that converts between an extended state where the projection screen extends substantially flat to display an image on a first side of the projection screen and on a second side of the projection screen, and a retracted state where the projection screen is retracted; a supporter that supports the projection screen so that the projection screen extends substantially flat when the projection screen is in the extended state; a storage that stores the projection screen when the projection screen is in the retracted state; a first projector that projects the image on the first side of the projection screen; a second projector that projects the image on the second side of the projection screen; a first user interface that receives a first operation to control the image from the first side of the projection screen; a second user interface that receives a second operation to control the image from the second side of the projection screen; a switcher that switches which of the first user interface or the second user interface has a control to control the image; a sensor that detects an object around the monitor device; a cleaner that cleans the projection screen when the projection screen converts between the extended state and the retracted state; and circuitry that
