“…Automultiscopic displays are devices that show different images according to the viewer's position without the support of dedicated glasses. Unlike autostereoscopic displays, automultiscopic displays simultaneously provide viewers with motion parallax and 3D illusions [3], [4]. Various approaches have been suggested, such as using lenticular sheets, parallax barriers, projector arrays, and integral imaging.…”

In this work, we present interactive automultiscopic content with mobile surface haptics for multimodal interaction. Our system consists of a 40‐view automultiscopic display and a tablet supporting surface haptics in an immersive room. Animated graphics are projected onto the walls of the room. The 40‐view automultiscopic display is placed at the center of the front wall. The haptic tablet is installed at the mobile station to enable the user to interact with the tablet. The 40‐view real‐time rendering and multiplexing technology is applied by establishing virtual cameras in the convergence layout. Surface haptics rendering is synchronized with three‐dimensional (3D) objects on the display for real‐time haptic interaction. We conduct an experiment to evaluate user experiences of the proposed system. The results demonstrate that the system's multimodal interaction provides positive user experiences of immersion, control, user interface intuitiveness, and 3D effects.

In this paper, behavioral circuit models of a stereoscopic 3-D liquid crystal display (LCD) and shutter glasses (SGs) are proposed. Until now, no study has been conducted on a model that can demonstrate the optical behavior of a 3-D LCD panel, because it includes black frame insertion. In addition, a circuit model of SGs should be established to completely illustrate the behavior of a stereoscopic 3-D LCD system. These circuit models can accurately predict the optical responses of dynamic transitions in 3-D LCD systems and those of SGs. We can then develop a complete behavioral model of the stereoscopic 3-D LCD system by combining the behavioral models of both the 3-D LCD panel and SGs. SmartSPICE simulations are performed to verify our model, which is implemented by an analog hardware description language, Verilog-A. On the basis of these simulation and measurement results, we can conclude that the proposed behavioral circuit models can accurately describe the optical responses of combined displays such as stereoscopic 3-D LCDs.Index Terms-Behavioral model, liquid crystal display (LCD), shutter glasses (SGs), stereoscopic 3-D.

“…LCDs are globally used for peripheral devices of personal computers, large televisions, digital information displays (DIDs), and mobile devices. [1][2][3][4] Therefore, it has become increasingly important to optimize the driving characteristics of LCDs depending on the diverse environments, especially in ambient temperatures. Ambient temperature is one of the most critical factors that directly affect the movement of liquid crystals (LCs).…”

Abstract. We propose an overdrive (OD) technology to precisely compensate for the temperature-dependent response characteristics of liquid-crystal displays (LCDs). The optical responses of LCDs are highly dependent on ambient temperature. After analyzing the optimized OD values, the new OD technology uses simple calculation logic instead of bulky OD lookup tables to obtain OD values of rising transitions over a wide range of ambient temperatures. We also show that it is possible to automatically adjust the optimum OD values depending on the ambient temperature. The results show that the proposed OD technology can improve motion image quality without any motion artifacts regardless of the ambient temperature. We expect that our proposed OD technology will ensure that LCD products have a consistent motion image quality regardless of the ambient temperature without any increase in cost.
