We have proposed a pseudo 3D display using perspective effect of the pictorial cues by projecting 2D images to real slanted surfaces from observer position. Large perceived inclined angle of a letter “T” around 80 degrees on the ceiling can be successfully achieved by increasing viewing distance to 3 m. Perceived inclined angles remain high at vertical observation angle under 30 degrees and horizontal observation angles under 4.4 degrees.
