Table 4
The features of specular optical illusion display, rotating fan display, Pepper’s ghost display, and binocular parallax stereoscopic display [30–40].
| Feature | Specular optical illusion | Rotating fan display | Pepper’s ghost display | Binocular parallax stereoscopic display |
|---|---|---|---|---|
| Resolution | High (depends on optical system) | Medium (LED blade density) | High (projection quality) | High (screen resolution) |
| Color Reproduction | Good (reflective surface limitations) | Limited (LED color range) | Good (depends on light source) | Excellent (full RGB spectrum) |
| Field of View (FOV) | Limited (mirror angles) | 180°-360° (depends on fan design) | 90°–120° | Wide-angle (varies by technology) |
| Depth Perception | Low (illusion-based) | Medium (perceived depth) | Medium (semi-transparent effect) | High |
| Interactivity | Low (passive viewing) | Medium (gesture control possible) | Low (static projection) | High |
| Cost Efficiency | Medium (high-precision optics) | Affordable | Expensive (large-scale projections) | High (depends on display type) |
| Limitations | Limited viewing angles; Critical alignment (mirrors) | Limited color accuracy; Vibration noise | Large-scale projection requirement; Limited interactivity | Vergence-accommodation conflict |
| Potential Improvements | Dynamic adaptive optics adjustments | LED density enhancement; Mini/Micro-LED adoption; Advanced contrast filtering | Holographic waveguide integration | Light-field displays; AI-driven depth synthesis |
