Abstract
Illumination testing is performed to passively check the health of a display of a shared device within a physical space, such as a conference room. A test pattern is output to the display within the physical space. Using a camera within the physical space, a test image of the physical space is captured while the test pattern is output to the display. A determination is then made as to whether the display is in a fail state by comparing the test image against a reference image depicting an expected illumination of the physical space according to the test pattern. Where the device is determined to be in a fail state, a notification indicating the fail state is transmitted to an administrator device to alert an administrator associated therewith of the fail state.
