Dalam pengenalan lingkungan sekolah pada siswa baru, umumnya siswa diajak untuk berkeliling sekolah sehingga calon siswa dapat memahami suasana lingkungan sekolah. SMKN 1 INDRAMAYU sendiri masih menggunakan brosur atau spanduk dalam pengenalan sekolah, oleh karena itu bagaimana mengenalkan SMKN 1 INDRAMAYU kepada calon siswa baru tanpa harus mengajak berkeliling. Dari permasalahan tersebut muncul sebuah gagasan untuk membuat aplikasi yang bisa memperkenalkan lingkungan dan memberi informasi serta bisa dijadikan sebagai media promosi SMKN 1 INDRAMAYU yakni menggunakan teknologi virtual reality untuk memvisualisasikan tempat di dunia nyata ke dalam tampilan 3 Dimensi (3D)In introducing the school environment to new students, students are generally invited to tour the school so prospective students can understand the atmosphere of the school environment. SMK 1 INDRAMAYU itself still uses brochures or banners in the introduction of schools, therefore how to introduce SMK 1 INDRAMAYU to prospective new students without having to take a tour. From this problem emerged an idea to create an application that can introduce the environment and provide information and can be used as a promotional medium for SMKN 1 INDRAMAYU, namely using virtual reality technology to visualize places in the real world into a 3 Dimensional (3D) display

The three-dimensional (3D) display technology has always been a hot spot in the display field. The core of augmented reality (AR), virtual reality (VR), and naked-eye 3D display are to visually regulate the light entering the human eye to form a binocular parallax, that is, a visual deviation in the image of the two eyes, which produces a stereoscopic sense in the human brain. In the AR and VR display field, we always pursue a perfect immersive visual experience, which poses great challenges to the wide field of view (FOV) and high resolution of the system. As a new type of polymer material, liquid crystal polymers are widely used in AR and VR because of their unique optoelectronic properties, such as scattering or transparency with the change of an applied electric field. In this paper, we review some key challenges in the field of AR and VR display, such as the well-known vergence-accommodation conflict (VAC), and propose solutions that have been proven effective. We introduce the important functions and optoelectronic properties of liquid crystal (LC) materials by describing in detail the working principle of polymer dispersed liquid crystal (PDLC), doublet geometric phase (GP) lens, and polymer-stabilized liquid crystal (PSLC). Finally, we summarize and discuss the main uses and challenges of liquid crystal materials in the field of AR and VR displays.

Potential Applications

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.
