Title: Immersive displays

Description:
FIELD OF TECHNOLOGY 
     The present disclosure relates to immersive displays such as three-dimensional (3D) displays for displaying virtual or augmented reality environments. 
     BACKGROUND 
     Immersive displays are becoming increasingly popular for the purpose of playing games in a virtual reality environment. These immersive displays may also be utilized for applications other than gaming, including, for example, augmented reality applications. The virtual world or augmented-reality is currently commonly perceived by the user based on two images, with each of the two images displayed close to a respective one of the user&#39;s eyes. 
     Such displays are often head-mounted and in many cases block out some or all of the real environment around the user in order to immerse the user, for example, in the virtual world. Thus, these displays may obstruct or block the user&#39;s vision of his or her surroundings. The virtual world or augmented-reality is perceived by the user based on images displayed very close to the user&#39;s eyes. 
     Improvements in immersive displays and applications or uses of such immersive displays are desirable. 
     SUMMARY 
     According to an aspect, an immersive display is provided. The immersive display includes a body, at least one display on the inside of the body for displaying images in front of at least one eye of a user, and a processor. The processor is coupled to the display and operable to obtain information utilized for displaying the images, identify a direction that a user is looking, identify a center of a field of view based on the direction that the user is looking, utilizing the information obtained, display a first portion of the images in a first area of the field of view and display a second portion of the images in a peripheral area of the field of view. The second portion of the images is displayed at one or both of a lower resolution and a lower refresh rate than the first portion of the images.

     DETAILED DESCRIPTION 
     For simplicity and clarity of illustration, reference numerals may be repeated among the figures to indicate corresponding or analogous elements. Numerous details are set forth to provide an understanding of the examples described herein. The examples may be practiced without these details. In other instances, well-known methods, procedures, and components are not described in detail to avoid obscuring the examples described. The description is not to be considered as limited to the scope of the examples described herein. 
     Because the display or displays of an immersive display may be very close to the user&#39;s eyes when the immersive display is worn by the user, the displays may render images and video in stereoscopic 3D to areas of the eyes that normally are presented with static non-stereoscopic 3D imagery, such as that part of a person&#39;s vision that normally sees the person&#39;s nose in one eye, and only monocular vision of the environment in that part of their field of view from the other eye. Presentation of stereoscopic 3D in areas not accustomed to seeing such imagery will very often cause motion sickness for the user wearing the display. Similarly, lack of the point of reference, which is removed when the nose and other normally static imagery that a person is accustomed to seeing in each separate eye is replaced with imagery from an immersive display, often causes the wearer to feel disoriented and also contributes to motion sickness. Additionally, a very high resolution, or large number of pixels, and a very high refresh rate is desirable in order to display images with sufficient clarity for virtual or augmented reality. Such high resolution and high refresh rate increases the demands on device resources such as processing power, memory, and bandwidth to transfer information to the immersive display. 
     The following describes an immersive display and a method of operating the immersive display. The method includes obtaining information utilized for displaying a first image in front of a first eye and a second image in front of a second eye of a user of the immersive display, excluding part of the information to yield adjusted information to occlude or replace first information from a first area of the first image and second information from a second area of a second image when displayed on the immersive display, and providing the adjusted information for displaying the first image absent the first area or in which a static image is displayed and the second image absent the second area or in which a static image is displayed on the immersive display. Thus, the display may replace the information for display in the first area with a static image to simulate, for example, a nose. Similarly, the display may replace the information for display in the second area with a static image to simulate, for example, a nose. 
     The following also describes a method of providing information for display on a display of an immersive display that includes obtaining information utilized for displaying a first image in front of a first eye and a second image in front of a second eye of a user of the immersive display, identifying a first area of the first image and a second area of the first image and identifying a third area of the second image and a fourth area of the second image, and displaying the first area of the first image and the third area of the second image utilizing first display attributes and displaying the second area of the first image and the fourth area of the second image utilizing second display attributes. The second display attributes differ from the first display attributes. 
     A system  100  for providing information for display on an immersive display is illustrated in  FIG.  1   . The system includes servers  102  that are coupled to a network  104  or networks, which includes the internet and may optionally include a cellular network through which several client devices, nodes, or terminals may be connected. In the example of  FIG.  1   , five client devices are coupled to the network  104 , including desktop computers  106 ,  108 ,  110 , a laptop computer  112  which is coupled to the network wirelessly through a modem  114 , and a smartphone  116 . The servers  102  store and execute software or firmware and communicate and cooperate with software and firmware on the client devices  106 ,  108 ,  110 ,  112 ,  116  via the network. The software and firmware on the client devices  106 ,  108 ,  110 ,  112 ,  116  also communicate and cooperate with software and firmware on respective immersive displays that may be worn by the users. 
     The servers  102 , utilizing the software or firmware, provide the virtual environment, which may be a three-dimensional virtual environment. The environment may be any suitable environment for a game, a social network or interaction site, a meeting environment, such as a boardroom or meeting room, a classroom, a conference room or any other room or other scene. The virtual environment provided is dependent on the application and may be dependent on any other suitable factor such as the number of participants. 
     The servers  102  also manage authorization of users via client devices to facilitate participation in the virtual environment by avatars representing the users. The avatars enter the virtual environment to take part in or attend an event such as a game, a social network event or interaction, a meeting, class, conference or other event. 
     The images, including the environment, may be provided to the client devices  106 ,  108 ,  110 ,  112 ,  116  for display utilizing the immersive displays, which may be, for example, head-mounted displays worn by the users. 
     A simplified block diagram of an example of an immersive display  200  is shown in  FIG.  2   . The immersive display  200  includes multiple components, such as a main processor  202  that controls the overall operation of the immersive display  200 . 
     The main processor  202  interacts with other components of the immersive display  200 , including, for example, a temporary storage device  204 , a memory  206 , a display device  208 , a speaker  210 , an auxiliary input/output (I/O) subsystem  212 , external cameras  214 , one or more internal cameras  216 , one or more microphones  218 , an orientation/movement sensor  220 , one or more proximity sensors  222 , a communication subsystem  224 , short-range communications  226 , a power source  228 , and, optionally, other subsystems  230 . 
     The temporary storage device  204  may be, for example, Random Access Memory (RAM) that stores data that is processed by the main processor  202 . The memory  204 , such as flash memory, is utilized for persistent storage. 
     The immersive display  200  provides video output through the display  208 , which includes an interface, a controller and a pair of displays to display images. The images displayed include a respective image in front of each one of the user&#39;s eyes such that a right side image is displayed in front of a user&#39;s right eye and a left side image is displayed in front of a user&#39;s left eye. In addition to the display  208 , output is provided via the speaker  210  or other audio output such as headphones or earphones. The auxiliary input/output (I/O) subsystem  212  includes an interface through which, for example, a USB controller or other peripheral device may be connected. 
     Input to the immersive display may be provided via external sensors or input devices such as the external cameras  214  mounted on the body of the immersive display  200 . The external cameras  214  may include multiple cameras to obtain images extending around the user, i.e., 360° around the user. The external cameras  214  may also include cameras to obtain images in an upward direction from the user, and in a downward direction from the user. Each of the cameras includes the functional components for operation of the camera, including the lens, the image sensor, and, optionally, a light sensor and light source, such as infrared light emitting diodes (LEDs). Thus, the cameras provide images of the user&#39;s environment or surroundings. The cameras may be one or more of visual light cameras, 3D sensing cameras, light field cameras, forward looking infrared cameras, near infrared cameras, ultraviolet cameras, or other imaging devices. 
     The terms upward and downward are utilized herein to generally describe direction of view of the external cameras  214  relative to the user when the immersive display is worn by the user and the user is in an upright position, and such terms are not otherwise limiting. 
     The one or more internal cameras  216 , referred to herein as the internal camera  216 , may be mounted on an inside of the body of the immersive display and includes the functional components for operation of each internal camera, including the lens, the image sensor, and a light source, which may be a light source in the non-visible spectrum, such as infrared LEDs. Although the interior of the immersive display  200  may be dark because exterior light is blocked out or partially blocked out, the light source provides sufficient light for use of the internal camera  216 . 
     The one or more microphones, referred to herein as the microphone  218 , may also be mounted in the body of the immersive display  200  to provide input by converting audible information to electrical signals, which may be processed by the main processor  202  and may be transmitted to another electronic device to which the immersive display  200  is coupled. For example, the immersive display may be coupled to a smart-phone, a laptop computer, a tablet, a desktop computer, a game device, and any other suitable electronic device. 
     The main processor  202  also receives signals from the orientation/movement sensor  220 , which is coupled to the body of the immersive display  200 . The orientation/movement sensor may be, for example, an accelerometer, a gyro sensor, or any other suitable sensor or combination of sensors that is or are utilized to detect direction of movement, direction of gravitational forces, and reaction forces so as to determine, for example, the orientation of the immersive display  200  and the movement of the immersive display  200 . 
     The one or more proximity sensors, referred to herein as the proximity sensors  222 , may provide additional input to the main processor  202  to detect the presence of objects that are near or proximal to the sensor and thus to the user when the immersive display  200  is in use. The proximity sensors  222  may be any suitable proximity sensors such as a capacitive or photoelectric proximity sensor. 
     The communication subsystem  224  receives signals from another electronic device such as the client devices  106 ,  108 ,  110 ,  112 ,  116  shown in  FIG.  1   , and sends signals to the other electronic device to which the immersive display is coupled. Thus, for example, the signals from the microphone  218  or signals from the external cameras  216  or from the internal camera  216  may be sent via the communication subsystem  224 . The communication subsystem  224  is also responsible for receiving signals from the other electronic device for processing by the main processor  202  to cause images, which may include video, to be displayed on the display  208  and for audio to be output through the speaker  210 . 
     The immersive display  200  optionally includes short-range communications  226  to perform various communication functions. For example, the immersive display  200  may include Bluetooth or infrared (IR) communications capability, for example, for communicating with a peripheral device or accessory. 
     The power source  228  may be one or more rechargeable batteries or a port to an external power supply to power the immersive display  200 . 
     The systems and subsystems that interact with the main processor  202  and are described herein are provided as examples only. Other subsystems  230  may also interact with the main processor  202 . 
     Utilizing the images from the internal camera  216 , the main processor  202  may be operable to track eye motion. To track eye motion, the user&#39;s pupils may be tracked when the immersive display  200  is in use. The eye motion tracking may also facilitate determination of what a user is looking at, for example, by triangulation to determine depth of an object or image that a user is looking at. Alternatively, the internal camera  216  may identify or track changes in muscles or muscle motion around at least one of the user&#39;s eyes to identify movement of the eye, or may track changes in shape of a lens of an eye or changes in shape of the lens of each eye to identify a focal distance, facilitating identification of the depth of focus of a user. 
     In one aspect, variable focal optical elements, such as the SuperFocus™ glasses may be utilized and controlled digitally to create a more realistic blur effect. Areas that are set to be blurred may be rendered with fewer pixels. 
     Based on the eye motion tracking, the direction that the user is looking may be identified. The direction may be, for example, an angle or angles, such as angular offset or offsets from straight ahead. Thus, when a user glances upwardly, downwardly, or to either side, the direction is identified and the images displayed utilizing the display  208  may be changed or adjusted based on the direction. 
     The main processor  202  is also operable to analyze the images from the internal camera to track or identify a change in facial expression. For example, the main processor  202  may utilize primary facial feature tracking by tracking features such as lips, nose, and eyes. Alternatively, or in addition, movement of parts of the face may be tracked. The main processor  202  may transmit facial expression data or an identification of the expression to the other electronic device to which the immersive display  200  is coupled via the communication subsystem  222 . 
     The main processor  202  is also operable to receive the image data from the external cameras and to transmit the data to the other electronic device, along with metadata for at least key frames for identifying the image data such that the images can be stitched together to provide images of the user&#39;s surroundings. Thus, the images from each of the cameras can be stitched together to obtain images of the user&#39;s entire surroundings. 
     When viewing images without using the immersive display  200 , a user&#39;s nose typically occludes part of the real space that is viewed. In other words, part of the real space cannot be seen without adjusting the direction or position of the head because the user&#39;s nose is in the line of sight or in the line of the peripheral vision. In virtual reality or augmented reality viewed through the immersive display, corresponding areas may be occluded from display. Areas that would correspond to a user&#39;s nose are not displayed to increase the user&#39;s perception that the virtual or augmented reality space is real. Thus, no image is displayed in the areas that would correspond to the location of a user&#39;s nose or a static image may be displayed. By providing no image or a static image in such areas, a stable reference is provided in the user&#39;s line of sight and the chance of experiencing motion sickness or the severity of the motion sickness experienced while wearing the immersive display  200  may be reduced. 
     In addition, because the display  208  of the immersive display  200  is very close to the user&#39;s eyes when the immersive display  200  is worn by the user, a very high resolution, or large number of pixels, and a very high refresh rate is desirable in order to display images with sufficient clarity for virtual or augmented reality. Such high resolution and high refresh rate utilizes more processing power. Replacing parts of the images with static images to simulate a nose reduces the number of pixels for which information is processed for display, thus reducing one or more of processing requirements, memory requirements, and bandwidth utilized to transfer information to the immersive display. 
     A flowchart illustrating a method of providing information for display on a display of an immersive display is shown in  FIG.  3   . The method may be carried out by software executed, for example, by one or more of the servers  102 , by one or more of the client devices  106 ,  108 ,  110 ,  112 ,  116 , by the main processor  202  of the immersive display  200 , or by a combination of these devices. Coding of software for carrying out such a method is within the scope of a person of ordinary skill in the art given the present description. The method may contain additional or fewer processes than shown and/or described, and may be performed in a different order. Computer-readable code executable by at least one processor to perform the method may be stored in a computer-readable medium, such as a non-transitory computer-readable medium. 
     Information is obtained for displaying on the display  208  of the immersive display  200  at  302 . The information includes information for displaying a right side image in front of a right eye and a left side image in front of a left eye of a user of the immersive display  200  to provide a virtual 3-D image for the user. The information may be information from an application and is utilized to display a scene from a game, a social network or interaction site, a meeting environment, such as a boardroom or meeting room, a classroom, a conference room or any other room or other scene. 
     Parts of the information are identified for exclusion from the information or for replacement with a static image at  304 . The parts of the information that are identified correspond to a first area of the right side image and a second area of the left side image. The first area and the second area correspond to areas at which a user&#39;s nose would occlude the field of vision in real space. Thus, the first area is at a left side of the right side image and the second area is at a right side of the left side image. 
     Other parts of the information that correspond to other areas may also be identified for exclusion or for replacement with static images. For example, in addition to the areas that correspond to the user&#39;s nose, other areas that correspond to typical locations of cheekbones or eye sockets or both may be occluded from the field of vision. The information that corresponds to these areas of each of the right side image and the left side image may also be identified for exclusion, which may further increase the perception that the virtual reality space or augmented reality space is real. 
     The parts of the information are removed from the information obtained to yield adjusted information at  306 . The adjusted information includes less information or data than the information obtained at  302 , prior to removing the identified information. Alternatively, the parts of the information are replaced with static images to simulate a user&#39;s nose. The static images may be displayed at a lower resolution and may be displayed at a slower refresh rate. 
     The adjusted information is then provided at  308  for displaying the first image without the first area and the second image without the second area, corresponding to the areas at which the user&#39;s nose is present. The static images may be displayed in the first area and the second area. 
     The method illustrated in  FIG.  3    is continuous such that the images are continuously updated on the display  208  of the immersive display  200  to display or play virtual reality or augmented reality video on the immersive display  200 . 
     By providing no image or a static image in the areas that correspond to the nose or other occluded areas, the amount of information that is required for displaying images on the display  208  is reduced. The amount of information required for rendering is reduced. Thus, the area of the display  208  on which information is rendered is reduced. The display  208  may also or alternatively be reduced in size, such that the display  208  does not extend to those areas at which information is not rendered. Alternatively, the display resolution may be reduced for such areas, for example, for rendering a static image. In one example, the amount of information transmitted from the one or more servers  102  may be reduced. 
     As indicated above, the method illustrated in  FIG.  3    and described above may be carried out by software executed, for example, by one or more of the servers  102 , by one or more of the client devices  106 ,  108 ,  110 ,  112 ,  116 , by the main processor  202  of the immersive display  200 , or by a combination of these devices. 
     Optionally, the static image that is displayed on occluded areas of the display may be customizable or configurable by the user. For example, the static image may be configured by the user to configure attributes of the image, such as size, shape, and skin tone of the static image, to simulate the user&#39;s nose. For example, such configuring may be carried out by selection of options from a menu or utilizing any other suitable method. 
     According to one example, the method is carried out at one or more of the servers  102  such that the server obtains the information from an application executed at the one or more servers  102  at  302 . The one or more servers  102  also identifies the parts of the information for exclusion, including the first area of the right side image and the second area of the left side image at  304  and the one or more servers  102  removes the information at  306  to yield adjusted information that excludes the identified information. The adjusted information is provided by the one or more servers  102  at  308 , to the immersive display  200  by sending the adjusted information to the immersive display  200 , via the respective client device. 
     According to another example, the method is carried out at the client device  106 ,  108 ,  110 ,  112 ,  116 . In this example, the client device obtains the information from the one or more servers  102  or from the immersive display  200 , for example, from images captured utilizing the external camera or cameras  216  of the immersive display  200  at  302 . The client device  106 ,  108 ,  110 ,  112 ,  116  identifies the parts of the information for exclusion, including the first area of the right side image and the second area of the left side image at  304  and the client device  106 ,  108 ,  110 ,  112 ,  116  removes the information at  306  to yield adjusted information that excludes the identified information. The adjusted information is provided by the client device  106 ,  108 ,  110 ,  112 ,  116 , to the immersive display  200  by sending the adjusted information to the immersive display  200  for displaying, on the display  208 , the right side image excluding at least the first area and the left side image excluding at least the second area. 
     According to yet another example, the method is carried out at the immersive display  200 . According to this example, the main processor  202  of the immersive display  200  obtains the information from the respective client device  106 ,  108 ,  110 ,  112 ,  116 , or from the one or more servers  102  via the respective client device  106 ,  108 ,  110 ,  112 ,  116 , or, for example, from images captured utilizing the external camera or cameras  216  of the immersive display  200  at  302 . The processor  202  identifies the parts of the information for exclusion, including the first area of the right side image and the second area of the left side image at  304  and the processor  102  removes the information at  306  to yield adjusted information that excludes the identified information. The adjusted information is provided by the processor  102 , to the display  208  of the immersive display  200  by sending the adjusted information to the immersive display  200  for displaying the right side image excluding at least the first area and the left side image excluding at least the second area. 
     As described above, the images displayed, utilizing the pair of displays, include a respective image in front of each one of the user&#39;s eyes such that a right side image is displayed in front of a user&#39;s right eye and a left side image is displayed in front of a user&#39;s left eye. Rather than utilizing generally symmetrical circular, rectangular or simple geometric shaped displays designed to maximize display of potentially viewable areas to all areas of each eye of the user, the immersive display may be constructed with displays that are shaped to only display environmental imagery to those areas of each eye that typically see such imagery in the normal course of use. For example, each display may be generally circular with the exception of a notch or area corresponding to a user&#39;s nose. Thus, each display is shaped to occlude an area to correspond with the user&#39;s nose. The displays may also be shaped to occlude areas corresponding to other facial features such as eye sockets and cheekbones. 
     Such shaped displays may be advantageous because areas of images are occluded by the shape of each display rather than by software, reducing processing time. Additionally, by reducing the total area of each display compared to a geometrically simple display, the total number of pixels of the display may be reduced compared to a circular display, for example, while still displaying images at the same very high resolution. 
     Optionally, an obstruction may be inserted into the body to cooperate with the body to simulate the nose. The obstruction may cooperate with the body of the immersive display  200  such that the obstruction is mechanically retained in the immersive display. 
     According to another alternative, the body of the immersive display  200  may be configured to receive obstructions to occlude areas of the display. In this example, a first obstruction is insertable into the body to cooperate with the body to occlude a first area of the first image and a second obstruction is insertable into the body to cooperate with the body to occlude a second area of the second image. The first obstruction and the second obstruction are sized and shaped to simulate a user&#39;s nose when inserted into the display to occlude the areas of the display. 
     A flowchart illustrating another method of providing information for display on a display of an immersive display is shown in  FIG.  4   . The method may be carried out by software executed, for example, by the one or more of the client devices  106 ,  108 ,  110 ,  112 ,  116 , or by the main processor  202  of the immersive display  200 , or by a combination of these devices. Coding of software for carrying out such a method is within the scope of a person of ordinary skill in the art given the present description. The method may contain additional or fewer processes than shown and/or described, and may be performed in a different order. Computer-readable code executable by at least one processor to perform the method may be stored in a computer-readable medium, such as a non-transitory computer-readable medium. 
     When viewing images utilizing the immersive display  200 , a high definition image in the center of the field of view of the user provides a sharper and more realistic image for an improved experience or more realistic experience than a lower definition image. Peripheral areas of vision, however, may be rendered at lower definition or slightly out of focus. In fact, corrective lens eyeglasses generally correct for vision in an area centered on the field of view, for example, in a circle directly in front of the eye. Outside of this area, the eyeglasses may not correct for vision or correction may be reduced such that the areas outside the center of the field of view are out of focus or blurred for the user. Similarly, sunglasses generally reduce the amount of sunlight coming into an area in front of each eye of the user. However, the sunlight may still enter the eye from other areas in the user&#39;s peripheral vision, around the sunglasses and thus, these other areas may appear overexposed. Thus, information outside of the area at the center of the field of view, also referred to as the peripheral area, may be displayed at a lower resolution than the information in the area at the center of the field of view, or at a lower refresh rate. 
     Information is obtained for displaying on the display  208  of the immersive display  200  at  402 . The information includes information or data that is utilized by the display  208  to display the images. The information includes information for displaying the right side image in front of a right eye and the left side image in front of a left eye of a user of the immersive display  200  to provide a virtual 3-D image for the user. The information may be information from an application and is utilized to display a scene from a game, a social network or interaction site, a meeting environment, such as a boardroom or meeting room, a classroom, a conference room or any other room or other scene. 
     Parts of the information utilized to display the images are identified at  404  for displaying different areas at different resolution. Part of the information utilized for displaying the right side image is identified for displaying a peripheral area of the image at a lower resolution compared to the remainder of the image. Part of the information utilized for displaying the right side image is identified for displaying a peripheral area of the image at a lower resolution compared to the remainder of the image. For example, information utilized to display any area that is outside a circular or elliptical area at the center of the field of vision may be identified as the peripheral area. Information utilized to display the peripheral area of the right side image and information utilized to display the peripheral area of the left side image may be identified. 
     To identify the part of the information utilized to display the areas of the image that are outside the area at the center of the field of view, the information utilized to display the area of the image at the center of the field of view in each of the right side image and the left side image may alternatively be identified, thus distinguishing between the information utilized to display the area of the image that is at the center of the field of view and the information that is utilized to display the areas that are outside the center of the field of view. 
     Optionally, the images from the internal camera  216  of the immersive display  200  may be utilized by the main processor  202  to track one or each of the user&#39;s pupils to identify the direction that the user is looking. The field of view may be identified based on the direction that the user is looking. For example, for each of the right side image and the left side image, an area at the center of a field of view may be identified by a circular or elliptical area centered on the direction that the user is looking. The information that is utilized to display the area at the center of the field of view is identified, thus distinguishing between the information utilized to display the area of the image that is at the center of the field of view and the information that is utilized to display the areas that are outside the area at the center of the field of view. 
     Alternatively or additionally, the internal camera  216  may identify or track changes in muscles or muscle motion around at least one of the user&#39;s eyes to identify movement of the eye, or may track changes in shape of a lens of an eye or changes in shape of the lens of each eye to identify a focal distance, facilitating identification of direction and depth of focus of a user. The center of the field of view of each of the right side image and the left side image may be based on such tracking and the size of the area that is identified as the center of the field of view may also vary based on such tracking. For example, a smaller center of the field of view may be identified when the depth of focus is greater as a user is viewing an object perceived to be a greater distance away. 
     According to an alternative embodiment, information that is utilized to display the area at the center of the field of view may be obtained and the information utilized to display parts of the image in the peripheral area may be created. For example, the information utilized to display the pixels in the peripheral area around the area at the center of the field of view may be created at the respective client device or at the immersive display  200 . The information may be created based on attributes of the displayed image in the area at the center of the field of view. Thus, the information to display the area at the center of the field of view is received at the respective client device and immersive display  200  and the information to display the peripheral area is created. 
     Information is provided to the display  208  of the immersive display  200  for displaying different areas utilizing different attributes at  406 . For example, the right side image and the left side image are provided to the display  208  for displaying at  406 . The area of the right side image that is at the center of the field of view is displayed utilizing first display attributes. The peripheral area of the right side image, outside the area at the center of the field of view, is displayed utilizing second display attributes. Similarly, the area of the left side image that is at the center of the field of view is displayed utilizing first display attributes and the peripheral area of the left side image, outside the center of the field of view, is displayed utilizing a second display attribute. 
     For example, the areas outside each area at the center of the field of view in each of the left side image and the right side image may be displayed at a lower resolution and with a lower refresh rate than each respective area at the centers of the field of view. 
     A plurality of parts of the information may be identified at  404  for each image. For example, information to display the area at the center of the field of vision may be identified. Information to display an intermediate area surrounding the area at the center of the field of vision may be identified and information to display an outer peripheral area may be identified. The information may be identified to display the area at the center of the field of vision at the highest resolution while displaying the intermediate area at a relatively lower, intermediate resolution, and displaying the outer peripheral area at a resolution that is lower than the intermediate area. In this example, three areas are identified in each of the right side image and the left side image and each of the areas are displayed utilizing different attributes. Other areas may be identified for displaying utilizing different attributes. 
     The method illustrated in  FIG.  4    is continuous such that the images are continuously updated on the display  208  of the immersive display  200  to display or play virtual reality or augmented reality video on the immersive display  200 . 
     In addition or alternatively, the immersive display  200  may include adjustable corrective lenses positioned to be located in front of the user&#39;s eyes when the immersive display is worn by a user. The adjustable corrective lenses are utilized to adjustably correct the user&#39;s vision while the areas of the images that fall outside the lenses remain unadjusted and therefore blurred to the user who would otherwise wear corrective lens eyeglasses. 
     In one aspect, where resolution, processing power, and/or other elements are insufficient to render a full field, simulated obstructive objects may be placed in the field. For example, in a concert, a person sitting in front of the user may don a large virtual “hat” to obstruct the user&#39;s view and reduce the area of the display for which the image must be rendered. 
     The described embodiments are to be considered as illustrative and not restrictive. The scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole. All changes that come with meaning and range of equivalency of the claims are to be embraced within their scope.
