Problems solved by technology

Since the picture is imaged through the depth of the screen, the viewer not only sees the desired front surface image as with conventional screens, but also sees undesired illuminated particles across the entire depth of the screen, which results in blurring and blurring Image

Embodiment Construction

[0038] figure 1 The schematic diagram in shows the basic building blocks of the invention. The best mode of carrying out the invention is through heat pump extraction equipment (1), using solid state elements such as thermoelectric (TEC) modules, compressor based dehumidification systems or other means that create a thermal differential to cause condensation build up for subsequent collection, from Water vapor is extracted from the ambient air (22). The extraction device (1) can be detached from the main unit to a separate location, for example above the particle cloud (5). The extracted condensate is stored in a storage tank (2), which may include an external connection (34), for additional refilling or for operation without extraction of the device (1). sending the condensate to a particle cloud manufacturing system (3) to be described further in this document, which converts the condensate into fine particles by mechanical, acoustic, electronic or chemical means, or a com...

Abstract

This invention comprises a method and system for displaying free-space, full color, high-resolution video or still images while simultaneously enabling the user to have real-time direct interaction with the visual images. The system comprises a self-generating means for creating a dynamic, non-solid particle cloud by ejecting atomized condensate present in the surrounding air, in a controlled fashion, into an invisible particle cloud. A projection system consisting of an image generating means and projection optics, projects an image onto the particle cloud. Any physical intrusion, occurring spatially within the image region, is captured by a detection system and the intrusion information is used to enable real-time user interaction in updating the image. This input / output (I / O) interface provides a display and computer link, permitting the user to select, translate and manipulate free-space floating visual information beyond the physical constraints of the device creating the image.

Description

technical field [0001] The present invention relates to input / output interfaces for increased realism, to free-space imaging displays, environments, simulations and interactions. Background technique [0002] Current techniques attempt to exploit existing techniques to create the vision of free-floating images through the manipulation of depth cues generated from 2D data. A few examples of these include stereoscopic imaging through shutters and polarizing glass, and autostereoscopic techniques consisting of lenticular screens directing light from conventional displays or real imaging devices using concave lens arrays. All of these techniques are limited by convergence and accommodation. This is caused by the difference between the original two-dimensional image from which the data was generated and the perceived spatial position. The result is eyestrain and fatigue for the user due to difficulty focusing on images that are perceived to appear but not actually present. [...
