Facilitating support functionalities through a support appliance device in advanced networks (e.g., 4G, 5G, and beyond) is provided herein. A method can comprise facilitating, by a support appliance device comprising a processor, a dedicated communication link with a remote support entity via a secure internet connection. The method also can comprise, based on a receipt of a request for an active session, establishing, by the support appliance device, the active session with the remote support entity via the dedicated communication link. Further, the method can comprise receiving, by the support appliance device, input data associated with an item. The method also can comprise outputting, by the support appliance device, an indication on the item based on the support appliance device being in proximity of the item. An instruction related to the indication can be controlled by the remote support entity and implemented by the support appliance device.

A meta projector includes an edge emitting device configured to emit light through a side surface thereof, a meta-structure layer spaced apart from the upper surface of the edge emitting device that includes a plurality of nanostructures having a sub-wavelength shape dimension smaller than a wavelength of the light emitted from the edge emitting device, and a path changing member configured to change a path of the light emitted from the edge emitting device so as to direct the path toward the meta-structure layer. The meta projector may thus be configured to emit a light pattern of structured light, based on directing the light emitted from the edge emitting device through the meta-structure layer, while having a relatively compact device size.
