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].

  • Interview Dec, 2002 Holovizio, the Holographic 3D Display of the Future
    Interview Dec, 2002 HoloVizio, the holographic 3D display of the future At this year’s radiology convention’s technical exhibition in Szeged, visitors could marvel a real world sensation, a display of the third dimension, the display which works on the basis of holography. On a 32 inch monitor, similar to the television monitor, vein conjunctions, ribs, a skull cut horizontally at the crown, and other anatomic formulas appeared one after the other. By standing opposite the monitor it became clear what the sensation was, the formulas appeared floating in the air, rising in front of the monitor’s flat screen, giving a real spatial experience. Stepping aside and looking behind the image, more and more details appeared to the viewer. We asked the inventor, Tibor Balogh, a Dennis Gabor-prize winner engineer and owner of the Holografika company about his invention. The interview was prepared by Dr. Éva Németh. What were the antecedents of you developing a real three dimensional display? To display something as if it was really there was an old dream. Looking at the hologram everyone asks, is the object really there? We would almost love to touch it. It is the concurrence of reality and imagination. Today’s displays are flat and everyone has got used to them. When we are looking at the TV screen, we know that we are seeing an artificial picture, no matter how much we improve the resolution, the colour and the quality of the picture, the image still appears artificial, meanwhile, if I look out the window we can see the real world.

  • A Low-Power Head-Mounted Phase-Only Holographic Display by Light-Weight Compression
    1 Realizing a Low-Power Head-Mounted Phase-Only Holographic Display by Light-Weight Compression Burak Soner, Erdem Ulusoy, A. Murat Tekalp and Hakan Urey Abstract— Head-mounted holographic displays (HMHD) are projected to be the first commercial realization of holographic video display systems. HMHDs use liquid crystal on silicon (LCoS) spatial light modulators (SLM), which are best suited to display phase-only holograms (POH). The performance/watt requirement of a monochrome, 60 fps Full HD, 2-eye, POH HMHD system is about 10 TFLOPS/W, which is orders of magnitude higher than that is achievable by commercially available mobile processors. To mitigate this compute power constraint, display-ready POHs shall be generated on a nearby server and sent to the HMHD in compressed form over a wireless link. This paper discusses design of a feasible HMHD-based augmented reality system, focusing on compression requirements and per-pixel rate-distortion trade-off for transmission of display-ready POH from the server to HMHD. Since the decoder in the HMHD needs to operate on low power, (a) only coding methods that have low-power decoder implementation are considered. Effects of 2D phase unwrapping and flat quantization on compression performance are also reported. We next propose a versatile PCM-POH codec with progressive quantization that can adapt to SLM-dynamic-range and available bitrate, and features per-pixel rate-distortion control to achieve acceptable POH quality at target rates of 60-200 Mbit/s that can be reliably achieved by current wireless technologies. Our results demonstrate feasibility of realizing a low-power, quality-ensured, multi-user, interactive HMHD augmented reality system with commercially available components using the proposed adaptive compression of display-ready POH with light-weight decoding.

  • Augmented Reality Smart Glasses in the Smart Factory: Product Evaluation Guidelines and Review of Available Products
    Received March 29, 2017, accepted May 8, 2017, date of publication May 12, 2017, date of current version June 28, 2017. Digital Object Identifier 10.1109/ACCESS.2017.2703952 Augmented Reality Smart Glasses in the Smart Factory: Product Evaluation Guidelines and Review of Available Products ANNA SYBERFELDT, OSCAR DANIELSSON, AND PATRIK GUSTAVSSON Department of Engineering Science, University of Skövde, 54128 Skövde, Sweden Corresponding author: Anna Syberfeldt ([email protected]) ABSTRACT Augmented reality smart glasses (ARSG) are increasingly popular and have been identified as a vital technology supporting shop-floor operators in the smart factories of the future. By improving our knowledge of how to efficiently evaluate and select the ARSG for the shop-floor context, this paper aims to facilitate and accelerate the adoption of the ARSG by the manufacturing industry. The market for ARSG has exploded in recent years, and the large variety of products to select from makes it not only difficult but also time consuming to identify the best alternative. To address this problem, this paper presents an efficient step-by-step process for evaluating the ARSG, including concrete guidelines as to what parameters to consider and their recommended minimum values. Using the suggested evaluation process, manufacturing companies can quickly make optimal decisions about what products to implement on their shop floors. This paper demonstrates the evaluation process in practice, presenting a comprehensive review of currently available products along with a recommended best buy. This paper also identifies and discusses topics meriting research attention to ensure that the ARSG are successfully implemented on the industrial shop floor.
