摘要： The human visual perception system is very complex, and producing a virtual reality or augmented reality system that facilitates a comfortable, natural-feeling, rich presentation of virtual image elements amongst other virtual or real-world imagery elements is challenging. A particular challenge is in presenting a true sensation of depth and in particular, surface depth. Disclosed is an augmented reality display system for delivering augmented reality content to a user where the system includes an image generating source to provide frames of image data, a light modulator to transmit light associated with the frames of image data, and a diffractive optical element. The diffractive optical element receives light associated with the frames of image data and directs the light to the user’s eyes. The , the diffractive optical element includes a diffraction structure having a waveguide substrate corresponding to a waveguide refractive index, a surface grating, and an underlayer disposed between the waveguide substrate and the surface grating. The waveguide substrate has a waveguide refractive index, and the underlayer has an underlayer diffractive index that is different from the waveguide refractive index.

摘要： Disclosed is a user display device, comprising: a housing frame mountable on a head of a user; a lens mountable on the housing frame; a projection subsystem coupled to the housing frame to determine a location of appearance of a display object in a field of view of the user based at least in part on a prediction of a predicted head movement of the user, and to project the display object to the user based on the determined location of appearance of the display object, wherein the location of appearance of the display object is moved in response to the predicted head movement exceeding a nominal head movement value and the projection subsystem partially compensating for a perceived pixel spreading in response to the predicted head movement by decreasing both a size and an intensity of a first set of pixels in an image frame associated with the display object based at least on respective size and intensity of another set of pixels in the image, wherein the nominal head movement value corresponds to a nominal speed or a nominal acceleration; and a first pair of cameras mountable on the housing frame to capture a field of view image as seen by eyes of the user, wherein the field of view image contains at least one physical object, wherein the captured field of view image is used to gather information regarding movements of the head of the user, wherein the information regarding movements of the head of the user only consists of a center of attention of the user, an orientation of the head of the user, a direction of the head of the user, a speed of movement of the head of the user, an acceleration of the head of the user and a distance of the head of the user in relation to a local environment of the user.

摘要： A wearable display device suitable for use in an augmented reality environment is disclosed. The wearable display device can include a projector configured to project light through diffractive optical elements that then distributed the light to multiple display regions. Each of the display regions can be arranged to project light out of the wearable display device towards an eye of a user. Since each of the display regions are positioned in different locations with respect to an eye of a user, the result is that each display region directs light in a different direction. In this way the apparent field of view for a user of the wearable display can be substantially increased.

摘要： Disclosed is a system for scanning electromagnetic imaging radiation. The system alleviates at least some of the challenges associated with imaging systems such as head mounted displays. These challenges include the pixel density of image sources, which is constrained by the minimum achievable pixel size. The system comprises a drive electronics system configured to generate at least one pixel modulation signal, at least one electromagnetic radiation source configured to modulate light from the at least one electromagnetic radiation source based on the at least one pixel modulation signal, a first waveguide configured to follow a scan pattern and produce a first projected field area, a second waveguide configured to follow a scan pattern and produce a second projected field area, a first scanning actuator operatively coupled to and configured to physically displace the first waveguide, and a second scanning actuator operatively coupled to and configured to physically displace the second waveguide. Each of the first waveguide and the second waveguide is operatively coupled to the at least one electromagnetic radiation source. The drive electronics system is configured to luminance modulate the output of at least one of the first waveguide or the second waveguide concurrent with the first projected field area overlapping with the second projected field area.
