Survey of Interactive Displays through Mobile Projections

Types Of Projected Displays

When it comes to different projected displays, we can distinguish between four types that differ in the amount of mobility they provide: Environmental Projectors, which as the name suggests are located in the environment, e.g. projectors installed in meeting rooms; Moveable Projectors which are not fixed in the environment but need to be set up before operation; Hand-Held and Body-Worn Projectors are fully mobile projectors that are either held in the hand, e.g. a projector phone, or worn on the body; Self-actuated Projectors presents the most mobile setting, in which the projector can move through the environment on its own. This categorization is visualized in Figure 1.
