Virtual Booth

Traditional holographic displays are often expensive and technologically demanding, limiting their accessibility in educational and commercial contexts. This project proposes a sustainable and cost-effective alternative: a do-it-yourself (DIY) hologram projector built using recycled materials. The objective is to design a practical, portable, and affordable 3D projection tool that can be used in classrooms, exhibitions, or promotional settings. The device is constructed by assembling four trapezoidal plastic pieces into a pyramid shape, which is then placed on a smartphone playing a quadrant-based hologram video. The reflected light creates a floating 3D illusion visible from multiple angles. Results show that the device is lightweight, reusable, and produces clear visual effects in dim environments. This project not only demonstrates technological creativity and sustainability but also holds commercialization potential through educational STEM kits. Its simplicity and relevance to 21 st-century learning make it practical implementation and broader impact.
