One variation of a method for augmenting surfaces in a space includes: at a projection system, recording a sequence of scans of the space; aggregating the sequence of scans into a projector-domain image of the space; detecting a set of objects in the projector-domain image; identifying an object, in the set of objects, as of a first type; detecting a surface proximal the object in the projector-domain image; defining an association between the surface and a content source based on the first type of the object; based on the association, warping visual content output by the content source according to a profile of the surface extracted from the projector-domain image; actuating a projector assembly in the projection system to locate the surface in the field of view of a light projector in the projection system; and projecting the visual content, via the light projector, toward the surface.

Methods and systems are provided for automatically selecting a target area to project content thereon. For example, a projection device receives content to be projected and content attributes of the content. The projection device also captures images of candidate areas and determines candidate area characteristics based on the captured images. The projection device generates a respective quality-of-projection indicator based on the content attributes and the candidate area characteristics. The projection device selects the candidate area with the highest quality-of-projection indicator as the target area on which the content is to be projected.
