A user may input one or more messages (e.g., visual or audio content) with respect to a projection device that is to project the messages to users within an environment. The user may additionally input related information that dictates a context and manner in which the messages are to be projected. The projection device may monitor the environment to identify users, events or actions within the environment. Upon detecting and identifying a particular user, the projection device may visually project the messages onto a surface within the environment, or may audibly output the messages within the environment, which may convey a particular meaning to that user. Optionally, the projection device may authenticate the user in order to determine that the user is the intended recipient of the messages.
