A wearable user interface device provides a display (e.g. an augmented reality display) for a user/wearer. The device includes a camera or other optical sensor and wireless communication capability. The camera or sensor provides an input to detect and possibly communicate with a lighting device or system. The communications and display capabilities allow the device to obtain and present lighting-related information to the wearer. For example, before installation, the device may identify a light fixture and communicate with a server to obtain information about fixture installation or configuration. As another example, the user can operate the device to identify and communicate with an installed fixture, to configure the fixture into a system (e.g. as part of a lighting group) or to check or repair fixture or system firmware. Hence, the device provides a wearable, interactive user interface for a variety of lighting-related functions.
