Abstract
The present invention discloses a revolutionary dual-spectrum multi-layer holographic projection system that fundamentally redefines the paradigm of human-computer spa- tial interaction by eliminating the necessity of wearable apparatus while simultaneously enabling tactile manipulation of volumetrically-rendered virtual objects. The system achieves this through an innovative architectural decoupling wherein visible-spectrum multi-projector arrays generate stratified holographic imagery across multiple depth planes, while a parallel infrared sensing subsystem performs continuous shadow-pattern analysis to extract precise three-dimensional positional information of the user within the interac- tion volume. This spectral bifurcation resolves the fundamental paradox inherent in prior art wherein projection and sensing mechanisms interfere through shared electromagnetic bands. The invention further incorporates a haptic feedback interface device that pro- vides synchronized tactile responses calibrated to the virtual object coordinates through dynamic spatial mapping algorithms. The system architecture enables unprecedented applications including glasses-free surgical navigation with anatomical stratification, in- teractive industrial design with tangible virtual prototyping, and spatial computing envi- ronments where digital objects coexist manipulably with physical artifacts. The technical innovation resides specifically in the synergistic integration of dual-band spectral decou- pling, shadow-based positional extraction algorithms, multi-layer volumetric rendering with depth navigation capabilities, and real-time haptic-visual synchronization protocols operating within a unified computational framework that transforms ordinary physical space into a computationally-responsive interactive medium without encumbering the user with head-mounted displays or body-worn sensors.
