A parallax correction method for a transparent display system is provided. The transparent display system includes a transparent display device located between a background object and a user. The parallax correction method includes the following steps. A gaze point is displayed on the transparent display device. An image including the transparent display device, the background object and the user is captured. At least two display anchor points and at least two corresponding background object anchor points are detected according to the image. The display anchor points are located on the transparent display device, and the background object anchor points are located on the background object. A plurality of visual extension lines extending from the display anchor points and the corresponding background object anchor points are obtained. An equivalent eye position of the ocular dominance of the user is obtained according an intersection of the visual extension lines.

A stereoscopic image display apparatus that is capable of being efficiently aligned using a remotely controlled alignment function and a method of displaying a stereoscopic image using the same are disclosed. The stereoscopic image display apparatus includes a polarizing beam splitter for spatially splitting image light emitted by a projector into at least one transmitted beam and at least one reflected beam based on polarized components, at least one modulator for adjusting the transmitted beam and the reflected beam such that the transmitted beam and the reflected beam have different polarization directions when a left image and a right image are projected by the transmitted beam and the reflected beam, an angle adjustment unit for adjusting the position on a screen on which the transmitted beam is projected in response to a first remote control signal, a remote-control alignment type reflecting member for adjusting the path of the reflected beam in response to a second remote control signal such that the reflected beam overlaps the transmitted beam projected on the position on the screen adjusted in response to the first remote control signal in order to form a single image, and a remote controller remotely connected to the angle adjustment unit and the remote-control alignment type reflecting member for transmitting the first remote control signal and the second remote control signal to the angle adjustment unit and the remote-control alignment type reflecting member, respectively.

A device and methods for displaying representations of objects, solids, and surfaces volumetrically in a medium containing one or more photochromic compounds comprising at least one UVA light source arranged to project a beam of UVA radiation and irradiate at least one portion of a display volume incorporating at least one display medium which includes at least one photochromic compound. The irradiance of the irradiated portion of the display medium being sufficient for clear-to-colored transitions of voxels of the display medium from a transparent state to a colored state. After a time period after the irradiation, the irradiated voxels activated in the colored state transition by a colored-to-clear transition into the transparent state.

A projection system includes a screen forming device configured to form a screen by ejecting liquid from a plurality of nozzles and a projector, acquires three-dimensional shape data formed by a three-dimensional coordinate system having an X axis, a Y axis, and a Z axis, divides the three-dimensional shape data in an X-axis direction to generate sectional shape data, acquires coordinates of the sectional shape data, executes matching processing for correlating the coordinates of the sectional shape data, pixels with which the projector draws an image, the nozzles of the screen forming device, and heights in an ejection space of the liquid ejected from the nozzles, and projects an image onto the screen according to the correlation by the matching processing.

A plasma generator including: a femtosecond light source that generates a laser pulse beam; a processor that computes a computer generated hologram; a spatial light modulator that modifies the laser pulse beam in accordance with the computer generated hologram; a three dimensional scanner optically coupled to the spatial light modulator to direct the modified laser pulse beam to one or more focal points in air; and a lens that focuses the modified laser pulse beam. The modified laser pulse beam induces a light emission effect at a one or more focal points that can be visible, audible, and palpable.

The invention relates to a flying device (701) arranged to fly in a space and to present an image in that space, a system comprising multiple flying devices (701) for presenting an image in a space and a method for presenting an image in a space using a flying device (701), wherein the flying device (701) is arranged to fly in the space under control of a control signal, the flying device (701) comprising one or more light units (731) arranged to emit multiple light beams (711, 712, 713) a communication unit arranged to receive the control signal and a processing unit arranged to control, based on the received control signal a position of the flying device and a light output of each of the multiple beams (711, 712, 713).

Now it is time to extend the capability of Internet to “Virtual Existence”; make a rapid change to “the 3D World”, both in real and animation environment; start the new Era of “the instant travels”; “stop the wasted time” with many hours of travelling with cars and replace (reduce) the cars with the best alternative: “Task-Ins Cubicle”. Task-Ins-Cubicle is “a round room”, equipped with Monitors, Cameras, Speakers, and Microphones inside and outside, equipped inside with a Control Console, Internet Connection, and with possibly seating or laying arrangement. The Local Cubicle communicates with a Remote Cubicle placed anywhere in the world. A person in the Local Cubicle is able to feel everything of the Remote Cubicle. Persons at the Remote Task-Ins Cubicle are able to feel the complete holographic existence of the person from the Local Task-Ins Cubicle. Remote Task-Ins Cubicle can be replaced with a virtual Emulation World, to enable 3D Experience with Games and Imaginary Worlds. It is possible to call the Task-Ins-Cubicle as a “Virtual Transportation Machine”. Local-Task-Ins-Cubicle allows virtual transportation to a Remote-Task-Ins-Cubicle at any remote place and at the same time allows another to transport itself from another Task-Ins-Cubicle to the Local-Task-Ins-Cubicle. Because Task-Ins-Cubicle does a complete round view of transmission in both directions, the walls of the Task-Ins-Cubicle at the remote site appears “transparent” so allowing a holographic viewing of the person or things inside. Task-Ins-Cubicle is a complete one solution for several usages at home: Working Office, Own Cinema Hall, Cinema, Concert Hall, Sport Hall, Travelling Vehicle, Meeting Cafe, Shopping Market, Gaming System, Emulation System, Learning School and even classical TV with full holographic viewing, and much more.

In one embodiment, a method includes retrieving a media content item for display on a projectable surface. The method includes sending, to an interaction device including a projector and a camera, instructions causing the camera to capture one or more images of the projectable surface, receiving the one or more images from the interaction device, and determining one or more attributes of the surface based on the one or more images.
