Exploring Future Benefits of Holographic Projection in Communicating and Expressing Information

The development of display technologies has provided diverse options for presenting information, including touch-sensitive high-definition screens, augmented reality (AR), virtual reality (VR), and holographic projection. However, each tool has its effects, and for the choice of an appropriate presentation, overall device costs and expected display outcomes must be considered. Despite holographic projection being relatively immature at a technical level, its convenience and uniqueness in delivering stereoscopic imaging without the need for additional devices signifies its value. We explored the prospects and applications of holographic projection in the competitive VR market. With continuous technological development and improvement, holographic projection has the potential to become a core tool for information presentation in various fields. With experimental methods and expert interviews, we proposed the development direction of holographic projection technology. Participants operated three different types of display tools during the experiment: 3D modeling, 2.5D holographic projection, and AR models. After the experiment, interviews were conducted to define questions from diverse perspectives and insights. Subsequently, the responses of interviewees were analyzed to identify issues and development directions. Industry experts were also invited for in-depth interviews and knowledge sharing to consolidate the competitiveness and feasibility of holographic projection in the market. As a result, five key development points for holographic projection technology were determined. (1) Enhancing human-machine interaction, (2) Naked-eye characteristics, (3) Integration with animation technology, (4) Displaying object presentations, and (5) Diversified application scenarios. The research results indicated that, on the display effectiveness aspect, holographic projection is comparable to most virtual head-mounted devices for the majority of users. To enhance market competitiveness, interactivity, interest, environmental adaptability, and diverse technologies need to be considered as development directions.
