Enhanced Depth Perception in Volumetric Displays ID: 2018-052

This technology introduces a novel method for enhancing depth perception and simulating virtual images in volumetric displays through optical trapping.

Technology Overview

The method described utilizes optical trap displays (OTD) to overcome the limitations of traditional freespace volumetric displays, which cannot produce virtual images due to the co-location requirement of light scatterers and image points. By adjusting the perceived motion parallax in response to viewer movement, this invention allows objects to appear at different depths than their actual physical locations, significantly enhancing the volumetric display's depth capabilities.

Key Advantages

• Enables the simulation of enhanced depth and virtual imagery within the display's volume
• Reduces the number of necessary emitters, lowering the complexity and potential cost of volumetric displays
• Allows for interaction with real objects within the display volume, enhancing user experience
• Incorporates anisotropic scattering to improve depth perception for multiple viewers simultaneously

Problems Addressed

• Overcomes the limitation of traditional volumetric displays in producing virtual images
• Enhances the depth perception beyond the physical limitations of the display's volumetric write volume
• Reduces hardware complexity and costs associated with creating high-quality volumetric displays

Market Applications

• 3D display manufacturing for entertainment and gaming industries
• Advanced medical visualization tools for diagnostics and surgical planning
• Educational tools for more immersive learning experiences in science and history
• Enhanced simulation environments for military and aerospace training programs
