Abstract
A multiplanar head mounted display (HMD) includes two or more artificial display planes for each eye located at optical distances that can be dynamically adjusted based on a location within a scene presented by the HMD that the user views. For example, a scene is presented on two or more electronic display elements (e.g., screens) of the HMD. A focal length of an optics block that directs image light from the electronic display elements towards the eyes of a user is adjusted using a varifocal system (e.g., an element that mechanically changes a distance between a lens system in the optics block and the electronic display element, an element that changes shape of one or more lenses in the lens system in the optics block, etc.) based on a location or object within the scene where the user is looking.
