“…However the proposed alignment pattern is still valid with the local non-uniformities, because some fluctuations cannot change the number of observed intended subpixels significantly. If the error is big enough to change the viewpoints or viewing distance, other correction methods should accompany [30][31][32]. In that case, the proposed alignment pattern is compatible with other correction methods.…”

We propose a novel calibration method which can be applied to all kinds of panel-type multi-view displays. We analyze how the angular, the axial, and the lateral misalignment affects the 3D image quality in a panel-type multi-view display. We demonstrate the ray optics simulation with a 3-view slanted parallax barrier system using pentile display for the quantitative calculation. Based on the analysis, we propose a new alignment pattern for all kinds of panel-type multi-view displays. The proposed pattern is sensitive to all of the angular, the axial, and the lateral misalignments. The high spatial frequency images and on and off alignment in the proposed pattern help observers to calibrate the system easily. We theoretically show the generality of the proposed alignment pattern and verify the pattern with image simulations and experiments.

3D surface display is a form of display that can be simultaneously viewable by multiple users from many viewing positions, without the need for any headgears. It provides actual stereoscopic display such that users can focus on an object with correct depth representations without any eye strains. Existing designs of the surface display are usually done in large scale, whereby the compactness of the system is not taken into consideration. This work focus on design of a portable compact surface display system with high resolution. The design has a set of linear actuators which in turn connected to pins, each represents a pixel of the object to be displayed. The heights of the pins can be changed by controlling the actuator which in turn produces a high resolution tangible 3D object appearing from the surface. A Graphical User Interface (GUI) is designed with MATLAB-Arduino interface provides the simulated and actual display. The use of micro-actuators and pins makes the system of higher resolution than existing display systems available in the market.978-1-4799-3975-6/14/$31.00 ©2014 IEEE

A compact collimated display system using an aspherical screen with a concave mirror is proposed. As the collimated display can provide a long viewing distance for the observer, it is commonly used for personal virtual flight simulators. To deliver a collimated image, the conventional collimated display requires a large system, but by using an aspherical screen with a concave mirror, the system size can be diminished. In this paper, a method of designing the compact collimated display system is demonstrated with simulation and experiment results. Also, a floating display and a depth camera for detecting hand gestures were combined with the proposed system for interaction.
