Holography is a well-known technique for sensing and displaying real-world three-dimensional (3D) objects. Reconstructions from digital holograms are typically displayed with regular two-dimensional (2D) screens and therefore lot of the 3D specific information is not passed on to the viewer during the display process. Mobile devices have interesting possibilities for displaying 3D data interactively. In this study, we show how nine viewers evaluated hologram reconstructions with a tilt based display system incorporated into a mobile device. Â© 2010 IEEE.
