While holographic technology is not an innovation, it has sparked renewed attention as a result of advances in adjacent industries. The concept itself dates back to 1947, when Dennis Gabor created it, and its fundamental principles go back even further. However, the technology remained mostly theoretical until the advent of lasers in the 1960s. This achievement constituted a watershed moment, establishing holography as a useful technology. Despite its original promise, holography's complexity and cost hindered its widespread use. However, recent technical advances in a variety of fields have reignited interest in the subject. This renewed focus may be seen in the growing popularity of holographic displays at festivals, the establishment of new technology-focused companies, and the development of unique holographic gadgets. This study focuses on the hardware of HueGlow, a holographic virtual assistant. We will look at the fundamental architectural assumptions that drive hardware design. A full examination of the technology and devices used will also be presented, as well as a clear explanation of the underlying concepts.
