An opto-electronic device (100) is disclosed. The opto-electronic device (100) comprises at least one sensor (106) configured to obtain head orientation data including information on an orientation of a user's head, a processing unit (112) configured to process the head orientation data so as to obtain self motion data including information on the user's self motion and to provide at least one visual cue (114) based on the obtained self motion data, and a display device (120) configured to display the at least one visual cue (114) at a dis-play (102) at least in a periphery of a visual field of the user. Further, a method for providing visual orientation is disclosed.

A system includes one or more sensors to detect one or more properties for a current user wearing a head-mountable display (HMD), control circuitry to select a user profile from a plurality of stored user profiles in dependence upon one or more of the detected properties, where each stored user profile is associated with a respective user and includes data indicative of one or more reference properties for the respective user, where the selected user profile includes data indicative of at least one reference property that is substantially the same as at least one of the one or more of the detected properties, and processing circuitry to generate at least one of audio and video content for output by the HMD in dependence upon the selected user profile and in response to the selection of the user profile.

An imaging device is presented for use in an imaging system capable of improving the image quality. The imaging device has one or more optical systems defining an effective aperture of the imaging device. The imaging device comprises a lens system having an algebraic representation matrix of a diagonalized form defining a first Condition Number, and a phase encoder utility adapted to effect a second Condition Number of an algebraic representation matrix of the imaging device, smaller than said first Condition Number of the lens system.

A near-eye display for displaying an image to a viewer has enhanced laser efficiency and enhanced eye-safety features. The display includes a laser source which generates one or more laser spots and a scan driver which scans the laser spots across an image field. The electrical energy consumption is minimized by modulating the laser source at 3 power levels —a near-zero level, a near-threshold level, and a lasing level—and by synchronizing the modulation with the scan driver. In another embodiment, the laser module generates two or more laser spots which scan non-overlapping lines on the image field. The scanning is configured to prevent the light intensity at the eye of a viewer from exceeding eye-safety levels, even in the event of a scanning malfunction.

An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. At least one lens among the first to the sixth lenses has positive refractive force. The seventh lens has negative refractive force. The lenses in the optical image capturing system which have refractive power include the first to the seventh lenses. The optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.

An apparatus includes a reflective beam shaper configured to receive an input optical signal having a first energy distribution and generate an output optical signal having a second energy distribution different from the first energy distribution. The reflective beam shaper includes multiple reflective mirrors including a first mirror and a second mirror. The first mirror may include a first aspheric reflector configured to reflect the input optical signal as a first intermediate optical signal having a changing energy distribution. The second mirror may include a second aspheric reflector configured to reflect one of the first intermediate optical signal or a second intermediate optical signal as the output optical signal. A third mirror may include a third aspheric reflector configured to reflect the first intermediate optical signal as the second intermediate optical signal having another changing energy distribution.

Examples are disclosed that relate to computer-based tracking of a process performed by a user. In one example, multi-modal sensor information is received via a plurality of sensors. A world state of a real-world physical environment and a user state in the real-world physical environment are tracked based on the multi-modal sensor information. A process being performed by the user within a working domain is recognized based on the world state and the user state. A current step in the process is detected based on the world state and the user state. Domain-specific instructions directing the user how to perform an expected action are presented via a user interface device. A user action is detected based on the world state and the user state. Based on the user action differing from the expected action, domain-specific guidance to perform the expected action is presented via the user interface device.

An image display apparatus includes a display unit having a screen that displays an image, an image generation unit that generates an image to be displayed on the screen, a Fresnel lens disposed at a predetermined distance from the screen, a specular-reflection preventing device that causes a rear surface of the Fresnel lens to move so as to be tilted at an angle at which incident light from a user side where a user sees the image is not specularly reflected to the user side, and an image correction unit that corrects image distortion caused by the specular-reflection preventing device.

A directional illuminator includes a light source, a pupil-replicating lightguide, and a tiltable reflector coupling the light source to the pupil-replicating lightguide. The exit beam angle of the light outputted by the pupil-replicating lightguide follows the in-coupling angle, and accordingly depends on the tilting angle of the tiltable reflector. The directional illuminator with steered light beam may be used to illuminate a display panel. Steering the illuminating light by the tiltable reflector enables one to steer the exit pupil of the display device to match the user's eye location(s).

A waveguide head-up display (HUD) includes a waveguide that includes a lower surface and an upper surface and is configured to receive an input and project, based on the input, at least one image from the upper surface and into an eyebox, and a prism arranged at least one of on and above the waveguide. The prism includes a lower surface facing the waveguide and configured to receive the at least one image and an upper surface opposite the lower surface configured to project the at least one image received via the lower surface of the prism. The upper surface of the prism is angled relative to the upper surface of the waveguide such that a first normal of the upper surface of the prism is different from a second normal of the upper surface of the waveguide.
