An image orientation system is provided wherein images (rays of lights) are projected to a user based on the user's field of view or viewing angle. As the rays of light are projected, streams of air can be produced that bend or focus the rays of light toward the user's field of view. The streams of air can be cold air, hot air, or combinations thereof. Further, an image receiver can be utilized to receive the produced image/rays of light directly in line with the user's field of view. The image receiver can be a wearable device, such as a head mounted display.

There is provided an image processing device that processes a projection image presented to a plurality of persons at the same time. The image processing device specifies an overlapping area in which fields of view of two or more users overlap based on information on each user, classifies objects included in the overlapping area into a first object group and a second object group, generates a common image common to all users, made up of the first object group, generates individual images different for each user, made up of the second object group, and determines an output protocol for displaying the individual images.

Disclosed are methods and systems for displaying content. In an aspect, a plurality of content items can be displayed on one user device according to user preference. An example method can comprise positioning a first set of pixels associated with a user device so that first content displayed via the first set of pixels can be viewable in a first viewing location. A second set of pixels associated with the user device can be positioned so that second content displayed via the second set of pixels can be viewable in a second viewing location. The second content can be different from the first content.
