20080231926 | Systems and Methods for Updating Dynamic Three-Dimensional Displays with User Input - A dynamic three-dimensional image can be modified in response to poses or gestures, such as hand gestures, from a user. In one implementation, the gestures are made by a user who selects objects in the three-dimensional image. The gestures can include indications such as pointing at a displayed object, for example, or placing a hand into the volume of space occupied by the three-dimensional image to grab one or more of the displayed objects. In response to the gestures, the three-dimensional display is partially or completely redrawn, for example by an alteration or repositioning of the selected objects. In one implementation, a system simulates the dragging of a displayed three-dimensional object by a user who grabs and moves that object. | 09-25-2008 |
20090237763 | User Interaction with Holographic Images - User input is facilitated through gestural inputs with displayed two and three-dimensional objects using a holographic device and film that displays a static, digitally generated, three-dimensional, autostereoscopic, full-parallax, real image and a digital projector that displays dynamic images. A system includes computer-detectable tags mounted on a user-wearable glove, and on a base plate that holds the holographic device. The system determines the locations of the tags, and calculates a location of a feature of the image based on the locations of the tags. The system also determines the location, pose, and gestural motion of the input device based on the location of the tags. The system further calculates a distance and direction between the input device and the feature of the image. | 09-24-2009 |
20090278057 | Pulsed-Laser Systems and Methods for Producing Holographic Stereograms - Pre-sensitization techniques can be used in conjunction with holographic recording materials to allow high quality holographic stereograms to be recorded in those holographic recording materials using pulsed lasers. Additional hologram production system hardware and software designs for use with pulsed lasers are disclosed. | 11-12-2009 |
20100033783 | Enhanced Environment Visualization Using Holographic Stereograms - Hologram production techniques can combine source data representing realistic information describing an environment with source data providing representational information describing a feature of the environment and/or some object interacting with the environment. The combined data is used to produce holograms, and particularly holographic stereograms including features that enhance the visualization of the environment depicted in hologram. A haptic interface can be used in conjunction with such holograms to further aid use of the hologram, and to provide an interface to secondary information provided by a computer and related to the images depicted in the hologram. | 02-11-2010 |
20120026565 | Duplicating Holograms - Methods and systems for optimizing hologram duplication, including illuminating a first master hologram to generate a first data beam modulated by the first master hologram, recording a first copy hologram using the first data beam and a reference beam, analyzing a light field generated by the first copy hologram, and generating a second master hologram to be used in recording a second copy hologram according to the light field generated and a desired light field. | 02-02-2012 |
20120062967 | Duplicating diffractive optical elements - Methods and systems for duplicating holograms, including illuminating a master hologram using a first portion of a beam to generate a data beam, recording a copy hologram using a second portion of the beam and the data beam, where the master hologram and the copy hologram are arranged such that the second portion of the beam avoids the master hologram. | 03-15-2012 |
20120287490 | Displaying 3D Imaging Sensor Data on a Hogel Light Modulator - Methods and systems for displaying 3D imaging data, including providing 3D imaging sensor data, processing the 3D imaging sensor data, the processing being configured to modify the 3D imaging sensor data into a modified format suitable for a hogel light modulator, and providing the modified 3D imaging data to the hogel light modulator. | 11-15-2012 |
20150296203 | Dynamic Autostereoscopic Displays - Display devices can be used to provide display functionality in dynamic autostereoscopic displays. One or more display devices are coupled to one or more appropriate computing devices. These computing devices control delivery of autostereoscopic image data to the display devices. A lens array coupled to the display devices, e.g., directly or through some light delivery device, provides appropriate conditioning of the autostereoscopic image data so that users can view dynamic autostereoscopic images. Methods and systems for calibrating a hogel display are also described, including generating calibration hogel data corresponding to a calibration pattern; generating a hogel light field from the calibration hogel data; detecting the hogel light field; and determining calibration data by analyzing a set of hogel properties in response to detecting the hogel light field. The methods and systems may further include generating a calibrated hogel light field by generating calibrated hogel data using the calibration data. | 10-15-2015 |
