A time‐multiplexed 3d display using steered exit pupils

Pupils' collaboration around a large display

Collaboration is acknowledged as a key element of learning. Thus, it is valuable to develop Information and Communication Technology applications that, being implemented on proper devices, can support collaborative learning. Large multi-touch displays appear to encourage collaboration by offering users a shared environment to act upon. However, little knowledge is available on the actual influe...

Tile-Based 3D Display Using A Reconfigurable Display Matrix

This paper presents a tile-based truly three-dimensional display system using a reconfigurable display matrix. The display surface is configured into a non-planar, discontinuous, and tile-wise shape according to the scene image’s depth information. Two prewarped scene images are projected onto the display matrix to account for projector occlusion. We describe the projector-based rendering proce...

Diffractive exit-pupil expander for display applications.

Two-dimensional binary diffraction gratings can be used in wearable display applications as exit-pupil expanders (EPEs) (or numerical-aperture expanders) to increase the size of the display exit pupil. In retinal scanning displays the EPE is placed at an intermediate image plane between the scanners and the display exit pupil. A focused spot scans across the diffractive EPE and produces multipl...
