1Loss of information

If text characters on a two-dimensional plane are used for information transmission, then information can be transmitted with high accuracy, but the user burden increases and user interest decreases

Engineering Contradiction:

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent transitions from two-dimensional text display to three-dimensional spatial display. By encoding information in three-dimensional space using light field technology, the system maintains high information accuracy while significantly reducing user burden. Users can visually perceive complex information structures in 3D space, eliminating the need for sequential reading of text characters.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent replaces the mechanical reading process with optical field-based visual perception. Instead of requiring users to sequentially process text characters through reading, the system uses synthesized light fields to directly present information in a visually perceptible three-dimensional format, leveraging the human visual system's parallel processing capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If light is used to transmit image information, then the amount of information transmitted increases and user burden decreases, but optical interference noise occurs during light propagation

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent acknowledges that optical interference noise is inherent in light propagation but converts this challenge into an advantage by using coherent light properties. The system utilizes the interference characteristics of coherent light to encode and decode information, transforming the harmful interference effect into a useful mechanism for information transmission through optical field processing.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent changes the parameters of light propagation by using synthesized light fields with controlled coherence properties. By adjusting the temporal and spatial coherence parameters of the light, the system optimizes the balance between information transmission capacity and interference noise levels, enabling high-bandwidth transmission while managing optical interference effects.

Inventive Principle:

Solution Approach 1:

The patent implements a multi-functional optical device that can perform both information display and communication functions using the same three-dimensional light field generation system. The device integrates light synthesis, spatial encoding, and visual presentation capabilities into a single system, reducing overall system complexity while maintaining high information transmission efficiency through three-dimensional display.

AI summary

In three-dimensional projective reverse transformation, a distance to a measured object is measured, and three-dimensional coordinate values of each point in the measured object corresponding to each of a plurality of pixels configuring an imaging sensor are calculated. In three-dimensional projective transformation, a three-dimensional shape of is a display object is set. Further, positions of a right side eye and a left side eye of a user with respect to a position of the display object are measured. A projected image or a projected movie corresponding to both eyes of the user is formed.
