Researchers have attempted to improve anatomical education with the inclusion of three-dimensional visualization, with the prevailing finding that 3D is beneficial to students. However, there is limited research on the relative efficacy of different 3D modalities, including monoscopic, stereoscopic, and autostereoscopic displays.

In this paper, we present mobile embodied 3D avatar to shift a rich experience of avatar from a virtual world to our real life with a new style of te- lepresence. Conventional telepresence research have focused on the exact re- creation of face-to-face communication at a fixed position in a specialized room, so there have been much less research on a life-sized mobile telepresence system despite many off-the-shelf mobile telepresence robots available. We propose various scalable holographic displays to visualize a life-sized avatar in an actual life. In addition, we introduce architecture to control embodied avatar according to user’s intention by extending popular architecture for a multimodal virtual human, namely SAIBA. Our primitive prototype system was tested with 5 simple avatar animations to embody with a wheeled platform robot and a life- sized transparent holographic display and proved realistic avatar’s movement complying user’s intention and the situation at the remote location of avatar.

Received: 11 January 2019; Accepted: 11 March 2019; Published: 20 March 2019 Abstract: In this paper, we propose a holographic three-dimensional (3D) head-mounted display based on 4K-spatial light modulators (SLMs). This work is to overcome the limitation of stereoscopic 3D virtual reality and augmented reality head-mounted display. We build and compare two systems using 2K and 4K SLMs with pixel pitches 8.1 µm and 3.74 µm, respectively. One is a monocular system for each eye, and the other is a binocular system using two tiled SLMs for two eyes. The viewing angle of the holographic head-mounted 3D display is enlarged from 3.8◦ to 16.4◦ by SLM tiling, which demonstrates potential applications of true 3D displays in virtual reality and augmented reality. Keywords: holography; holographic display; digital holography; virtual reality 1. Introduction Virtual reality (VR) and augmented reality (AR) have been hot topics recently, and 3D technology is an important part of VR technology [1].

Successful application of the photo-alignment technique is considered to be a critical breakthrough. A variety of display and photonic devices with azo dye aligned ferroelectric liquid crystals is presented: smart glasses, liquid crystal Pancharatnam–Berry phase optical elements, 2D/3D switchable lenses, and laser therapy devices. Comparison of electro-optical behavior of ferroelectric liquid crystals is described considering the performance of devices. This paper facilitates the optimization of device design, and broadens the possible applications in the display and photonic area. Keywords: photo-alignment of ferroelectric liquid crystals; electro-optic modes; new devices; imaging technologies; displays; photonics 1. Introduction The appearance of portable and wearable devices has led to an ever-increasing demand for next-generation displays with ultra-high resolution, light weight, low power consumption, and high efficiency [1,2]. However, the response time of nematic liquid crystals (LCs) is too slow for fast-switching devices.
