Abstract: Disclosed are systems and methods for visualizing workplace layout safety. A data structure of a workplace layout is processed to identify workplace objects and determine their respective locations. Likely locations of individuals are determined, corresponding to locations of the workplace objects. Safety parameters indicative of a required minimum separation between individuals are received, and a 3D model representation of the workplace layout is generated with a plurality of safety zones, each of the safety zones having a location corresponding to one of the likely locations of individuals in the workplace layout, and having a size corresponding to the safety parameter. Interference between at least two of the safety zones is determined, and a visual representation of the workplace layout is generated using the 3D model representation with a first visual indicator indicative of the safety zones, and a second visual indicator indicative of the determined interference between safety zones.

Abstract: In one embodiment, a client device of a first user associated with a first node in a social graph of a social-networking system accesses a tag that encodes information regarding a second node in the social graph; determines based on the tag a social action to take one the social graph with respect to the first and second nodes; and transmits to the social-networking system a message configured to effect the social action on the social graph.
